WHEN IS THE BET AWARDS COMING ON

Continous donor site local anaesthetic infusion for the prevention of persistent postoperative pain after iliac crest bone graft harvesting. Including an additional RCT with continuous outcomes in a Bayesian evidence synthesis further strengthens the evidence favouring the intervention Blumenthal Table 5. Continous intravenous local anaesthetic infusion for the prevention of persistent pain after breast cancer surgery.

These two studies are however consistent and of high methodological quality. Pain arising from a surgical intervention and persisting beyond three months is termed persistent postoperative pain PPP Kehlet PPP continues to be frequent and is sometimes severe, but often neglected Bayman ; Gewandter ; Kehlet ; Perkins Young age, the surgical procedure and perioperative pain predict PPP, while genetic risk factors remain unknown Lewis ; Montes PPP may be only mild or it may be severely disabling Kehlet Most clinical studies focus on acute postoperative pain, and few address the preventive effects of regional anaesthesia on PPP MacRae ; MacRae Recent reviews deplored the poor quality of available studies and documented the high event rate after a variety of surgical interventions, from hernia repair to breast surgery MacRae ; MacRae Our current review focuses on the ability of local anaesthetics or regional anaesthesia to reduce the risk of PPP.

Pain pathways, and hence pain perception, can be modulated, sensitized and permanently altered Woolf Before or after surgery, local anaesthetics may be applied locally to interrupt the conduction of pain impulses from the site of injury to the central nervous system.

If local anaesthetics are applied locally at the site of surgery this is called local anaesthesia. If local aesthetics are applied close to nerves, but at a distance from the surgical site, this is called regional anaesthesia. Sometimes, local aesthetics are also applied intravenously.

All three modes of administration of local aesthetics may prevent the central sensitization described in the Description of the condition. Epidural and spinal anaesthesia act at the nerve roots while nerve blocks, plexus anaesthesia and wound infiltration inhibit peripheral nerves. By blocking sympathetic nerves, local anaesthetics may also have desirable effects on bowel motility or unwanted effects on blood pressure.

Systemically for example intravenously administered local anaesthetics might also exert beneficial effects including preventing PPP, hyperalgesia and allodynia Duarte ; Herroeder ; Lavand'homme ; Strichartz ; Vigneault The local and regional anaesthesia techniques described above can be used as an alternative or in addition to conventional pain control. They are administered systemically and, therefore, often cause systemic side effects that limit their use, like the nausea and constipation caused by opioids or kidney damage as a result of use of NSAIDs.

We have provided an explanation of regional anaesthesia and conventional analgesia in Appendix 1. We hypothesize that preventing pain transmission using local or regional anaesthesia during or soon after surgery, or both, reduces the risk of PPP Atchabahian b ; Woolf Local anaesthetics applied close to the nerves will block pain perception and prevent the central sensitization in the spinal cord that leads to hyperalgesia and PPP Kehlet see: Description of the condition. However, systemic toxicity of local anaesthetics is well described Brown , either as a side effect after absorption or when given intravenously Herroeder ; Strichartz The actual mechanism remains elusive Strichartz Our review focused on preventive analgesia.

We defined preventive analgesia as antinociception with local anaesthetics or regional anaesthesia to reduce the risk of PPP regardless of the timing of the intervention in relation to surgery Kissin We did not study if local anaesthetics or regional anaesthesia were more effective if applied before, during or after surgery Bong ; Lavand'homme PPP is frequent and difficult to treat Kehlet Hence prevention of PPP is paramount Gewandter We are interested in investigating whether local anaesthetics or regional anaesthesia prevent PPP several months after surgery.

Clinical trials report conflicting results. For example, epidural anaesthesia may reduce the risk of PPP after thoracotomy Ju ; Lu ; Senturk , but these effects have not been consistently reproduced Ochroch We did not find enough studies to allow us to make inferences for other surgical subgroups. Terkawi a sought to synthesize the evidence on paravertebral block for the prevention of PPP, but found the outcome reporting of available randomized controlled trials RCTs disparate and hence evidence synthesis difficult.

We included studies with a randomized, controlled design. However, blinding of the outcome observer was a prerequisite for inclusion in this review. We included studies in adults and children undergoing elective surgical procedures, encompassing general, thoracic, abdominal, vascular, gynaecological and other surgery.

This included the main groups of surgery with a high event rate of persistent pain after surgery, such as breast surgery, limb amputation and thoracotomy, but also groups with a lower baseline risk but high surgical volume, such as caesarean section. We excluded studies in participants undergoing orthopaedic procedures as they are covered by another Cochrane Review Atchabahian a.

We included studies comparing local anaesthetics or regional anaesthesia versus conventional pain control Appendix 1. We included studies comparing local anaesthetics and regional anaesthesia versus conventional pain control. Our primary outcome was persistent postoperative pain PPP at three or more months after surgery.

We defined PPP as new pain, which did not exist before the operation , but lasting beyond three months after surgery. We defined our primary outcome of interest as a dichotomous contrast, namely the presence versus absence of pain elicited at that clinical encounter. We accepted the dichotomous pain outcomes as reported in the studies, mostly contrasting pain versus no pain, even though definitions varied at times.

Some primary study authors define the presence or absence of pain in their study as pain exceeding a given threshold on a continuous pain scale, analogous to responder analysis. We accepted the thresholds used by the study authors, though they sometimes employed different scales or instruments. This responder analysis Andreae c ; Dworkin a , also employed during our previous version of this review Andreae , counts the number of people with an outcome above a defined threshold.

Responder analysis informed our approach to missing data imputation Andreae b , as detailed below Dealing with missing data. We discussed responder analysis and the heterogeneity of outcome reporting in greater detail in Overall completeness and applicability of evidence. We also assessed differences in scores based on validated pain scales, such as the visual analogue scale VAS ; the verbal rating score; or the McGill pain questionnaire Dworkin b.

Acceptable continuous measures for allodynia or hyperalgesia may, for example, be the area of punctuate allodynia or hyperalgesia measured with von Frey hair Lavand'homme For adverse events we accepted any definition by the authors of the primary studies, who in the previous version of this review Andreae , sparsely reported on adverse events and most anecdotally or in narrative form.

We discuss in Overall completeness and applicability of evidence , that registries are better suited to assess adverse events after regional anaesthesia given their rare occurrences. We performed an electronic search of common databases and handsearched reference lists of relevant studies and conference abstracts. We performed an additional search in December and added the results to Studies awaiting classification to be incorporated into the next update of this review.

We combined a free text search with a controlled vocabulary search, covering from the inception of the database to the present. We conducted a handsearch of the reference lists of included studies, review articles and other identified relevant studies for additional citations, and in the conference abstracts of the International Anesthesia Research Society IARS and the European Society of Regional Anaesthesia ESRA for through to Because the yield of the handsearch was very low, we did not update this search in We followed links for related articles in Pubmed Central.

The study flow diagram documents the search and selection process. We included 63 studies. We were able to pool data from 39 of the 63 included studies in our inclusive analysis; data from 24 studies were not available or otherwise could not be pooled Appendix To avoid location bias, all articles detected by our search, but not available via online subscription of our institutions were requested through interlibrary loans.

For studies that appeared to be eligible RCTs, we obtained and inspected the full articles to assess their relevance based on the preplanned criteria for inclusion. We noted the reasons for study exclusion and inserted them into the Characteristics of excluded studies table. We recorded details of study design, participant characteristics, interventions and outcome measures.

We performed a pilot run and revised our data sheet accordingly, published as an appendix in our previous review Andreae Where dichotomous data on persistent postoperative pain were not reported, we attempted to obtain these from the study authors.

We extracted the following secondary outcomes, where provided: allodynia and hyperalgesia, use of pain medication. We also extracted the following data: exclusion criteria; comorbidity; regional anaesthesia technique and local anaesthetic used; quality assurance of the intervention; quality of pain control; assessment of hyperalgesia and allodynia; use of adjuvants; and surgery performed. We extracted data on adverse effects and attrition. We contacted study authors for missing information regarding their methods.

We graded study quality in a 'Risk of bias' table on the basis of a checklist of design components. We extracted information on conflicts of interest and funding see: Characteristics of included studies. We achieved consensus by informal discussion. We judged risk of bias to be unclear, high or low Higgins a. In regional anaesthesia interventions, blinding of participants and anaesthesia providers can be difficult and hence this criterion received less weight in the evaluation of performance bias, but not with regard to detection bias.

We listed excluded studies with detailed reasons see: Characteristics of excluded studies. In response to the first version of this review Andreae b , clinicians expressed concern about null bias. Null bias might cause studies to underestimate the benefit of regional anaesthesia for the prevention of persistent pain after surgery, if the regional anaesthesia interventions were not effectively delivered Higgins a ; Woods Indeed, a number of included studies reported no improved pain control in the immediate postoperative period in the experimental regional anaesthesia group, as evidenced by inconsequential differences in pain scores between groups perioperatively, or similar requirements of rescue analgesic medications between groups in the immediate postoperative period Barkhuysen ; Baudry ; Bollag ; Can ; Choi ; Fassoulaki ; Ibarra ; Ju ; Karmakar ; Katz ; Lam ; Lee ; Liu ; Loane ; McKeen ; Micha ; Purwar ; Singh ; Smaldone ; Terkawi b ; Vrooman ; Xu ; Zhou Two review authors therefore extracted information on null bias for each included study and documented their judgement with supporting evidence see: Characteristics of included studies.

As the summary statistic for our dichotomous primary outcome, we chose the odds ratio OR Bland We calculated the number needed to treat for an additional beneficial outcome NNTB for the surgical subgroups, for example, for thoracotomy and breast cancer surgery, but not for the overall effect across all types of surgery Cook The planned integration of dichotomous outcomes with continuous outcomes implied the use of ORs see: Data synthesis.

After this integration turned out to be of marginal importance for our analysis, we decided to stick to our protocol to eliminate any reasonable doubt about a postanalysis decision that might inappropriately influence our results Andreae For the continuous pain scales we calculated the mean difference between groups when all studies in a given subgroup used the same scale, and standardized mean differences SMD between groups when studies being compared used different scales.

Some studies have the surgical site e. For our inclusive evidence synthesis Analysis 1. Comparison 1 Local or regional anaesthesia for the prevention of persistent postoperative pain inclusive analysis , Outcome 1 PPP three to 18 months after thoracotomy. Comparison 1 Local or regional anaesthesia for the prevention of persistent postoperative pain inclusive analysis , Outcome 3 PPP three to twelve months after breast cancer surgery.

Comparison 1 Local or regional anaesthesia for the prevention of persistent postoperative pain inclusive analysis , Outcome 9 PPP three to 12 months after hernia repair.

Comparison 1 Local or regional anaesthesia for the prevention of persistent postoperative pain inclusive analysis , Outcome 10 Pain score three months after prostatectomy. We checked with the study authors for any missing information and reported data inconsistencies in the Characteristics of included studies. We specified in the tables if we were unable to obtain data. We grouped studies in subgroups based on surgical interventions.

We feel these differences argue against pooling or comparing studies across surgical disciplines Deeks We investigated study heterogeneity at the subgroup level using a Chi 2 test and calculation of the I 2 statistic Higgins We followed the thresholds suggested in the Cochrane Handbook for Systematic Reviews of Interventions for the interpretation of I 2 statistic Deeks We contacted study authors to request missing data.

We countered time lag bias by repeating our search just prior to submission of our work. We considered an examination of publication bias using graphical and statistical tests e. We thereby followed Ioannidis , who explicitly proposed Bayesian methods to synthesize heterogeneous studies to overcome disparity in study design and reporting. Frequentist inference, throughout this review, refers to the classical statistical approaches of significance and hypothesis testing proposed by Fisher and Neyman—Pearson, respectively, in contrast to the Bayesian statistical paradigm of updating a prior probability with new data Andreae c ; Andreae ; Gelman For the inclusive evidence synthesis, we did not pool the data across different surgical disciplines.

Instead, we grouped studies in broad surgical categories e. Where we had sufficient studies for a surgical procedure, that is, the inclusive analysis in breast surgery Analysis 1. For example, in Analysis 1. This predictably would lead to smaller bins and hence to more variability in the estimate, including possibly contradicting results when pooling the same studies, but repeatedly at subsequent intervals.

Anticipating that some studies would report only dichotomous outcomes while other studies would report only continuous outcomes Andreae , we had planned to pool the results in one comprehensive Bayesian hierarchical model Andreae a ; Ioannidis We started with a Bayesian hierarchical model for the surgical subgroup of iliac crest bone graft harvesting ICBG. Where dichotomous aggregate data were not available, we estimated the dichotomous data from the continuous data presented for Blumenthal Andreae b.

We then pooled the data in a Bayesian model Andreae b , implemented in the statistical software OpenBugs Lunn , with the model code presented in Appendix 6. We used weak priors for effect estimates. We compared results based on this informative prior with results based on a weak uninformative prior Andreae b ; Andreae ; Gelman In this we considered the argument by Shrier, that observational studies did not differ in their effects of interventions Shrier We assessed convergence looking at trace plots of our simulations.

For studies with several groups using local or regional anaesthesia, albeit with varying use of adjuvants or different timing of the intervention with regards to the surgical procedure, or both, we pooled all groups employing local or regional anaesthesia and compared them against the comparator. Similarly, if there were multiple study groups using different regional anaesthesia, one with and one without an adjuvant analgesic, we pooled the results from both groups and compared them to the control group using conventional analgesic methods.

Where there were enough studies in one group, we calculated the I 2 statistic Higgins We followed the thresholds suggested in the Cochrane Handbook for Systematic Reviews of Interventions for the interpretation of the I 2 statistic Deeks We investigated studies employing adjuvant therapy, using different regional anaesthesia modalities, and studies providing continuous postoperative regional anaesthesia as a subgroup.

We tested the sensitivity of our results to our model assumptions and calculated the effect estimates for our pooled subgroups e. These tables summarize the magnitude of the effects of the interventions examined, the total sum of all available data and their consistency, weighing them against the internal and external validity of the studies, or lack thereof.

We assessed the overall quality of evidence for each outcome. We downgraded the evidence from 'high quality' by one level for serious or by two levels for very serious study limitations risk of bias, e. We reported the effect of local or regional anaesthesia on the prevention of PPP at three months or beyond by surgical subgroups after thoracotomy Table 1 , breast cancer surgery Table 2 ; Table 5 , caesarean section Table 3 , and ICBG Table 4.

The searches for this updated review were undertaken in September to January , again in April , and for a final time in December For the original review, the searches were undertaken in February and March and rerun between February and August and again between April and May Andreae The search and selection process is illustrated in a flow diagram Figure 1.

We added 11 study reports from an updated search in December to Studies awaiting classification. We did not repeat the handsearch for this update. For the first version of this review Andreae , in our handsearch of the conference proceedings, we looked at references. We found references in the reference lists of included studies or review articles, or by following links in PubMed and Google to other relevant studies.

This resulted in a total of references; were duplicates and were excluded as irrelevant or not RCTs. Seven study reports were only available as a conference abstracts. We were able to resolve all disagreements with regard to data extraction, study inclusion and quality assessment by informal discussion. Data extraction and quality assessment for the remaining four studies was resolved with help from the respective study authors Besic ; Choi ; Micha ; Tecirli We identified 63 RCTs studying regional anaesthesia or local anaesthetics for the prevention of PPP in this updated review see: Characteristics of included studies , 40 of these were newly included in this update.

For ease of orientation, Appendix 7 summarizes the surgical operations, type of anaesthesia, timing of intervention, adjuvant therapy and outcomes of the pooled studies. Four included studies reported their results in several published manuscripts Kairaluoma ; Katz ; Katz ; Singh When two manuscripts were published by the same authors and reported the same participant numbers, we judged them to be reporting on just one and the same study; we used this data set only once Kairaluoma ; Katz ; Katz ; Singh We pooled the data of study participants in our inclusive analysis Appendix 8 , with participants after thoracotomy, participants after cardiac surgery, participants after breast cancer surgery, participants after caesarean section, participants after ICBG, participants after prostatectomy, participants after hysterectomy, with outcomes ranging from 3 to 48 months after surgery.

We pooled the data organized by surgery type with outcomes at 3, 6, 12, 20, or 48 months. A breakdown of the number of participants by surgery and time point is provided in Appendix 8. Reflecting the diversity of surgical interventions, the participants' age, sex and comorbidities varied widely and were sparsely reported.

Breast surgery and caesarean section studies included only female participants. Studies on limb amputation included predominantly male participants. We listed the surgical interventions investigated in the pooled studies thoracotomy, breast cancer surgery, hysterectomy, ICBG, caesarean section, prostatectomy in Appendix 7.

We grouped studies in broad categories thoracotomy, cardiac surgery, breast surgery, caesarean section, laparotomy, and prostatectomy with similar characteristics. We summarized the use of regional techniques in Appendix 7. Epidural anaesthesia was used in majority of the thoracotomy studies Can ; Comez ; Ju ; Lu ; Senturk Exceptions included one study using intercostal nerve block Katz , and one employing wound irrigation Liu Wound irrigation and instillation were used in three of the studies on ICBG Blumenthal ; Gundes ; Singh , while local infiltration techniques were used in the others Barkhuysen ; O'Neill For laparotomy surgery, both studies employed epidural anaesthesia Katz ; Lavand'homme , whereas in hysterectomy both studies employed spinal anaesthesia Sprung ; Wodlin The experimental arms in two studies on breast cancer surgery used intravenous lidocaine Grigoras ; Terkawi b.

In thoracotomy, all studies used continuous regional anaesthesia in the perioperative period. In the breast cancer surgery subgroup, only those with topical Fassoulaki ; Fassoulaki , or intravenous administration Grigoras ; Terkawi b , of local anaesthesia used continuous perioperative regional anaesthesia.

In the remaining surgical subgroups, there were only a handful of studies utilizing continuous application of regional anaesthetics Brown ; Chiu ; Gupta ; Lavand'homme ; Pinzur ; Vrooman The latter comparison was not planned in our protocol and hence these data were not presented. As a prerequisite for inclusion, studies had to employ an instrument to subjectively measure patient discomfort Appendix 7.

The study authors primarily used a dichotomous outcome, that is presence or absence of phantom pain. Nine studies did not record pain as a dichotomous outcome but only used continuous pain scales Blumenthal ; Chiu ; Gupta ; McKeen ; O'Neill ; Singh ; Sprung ; Vrooman ; Wodlin One did record pain as a dichotomous outcome but did not report it in the manuscript, and provided the review authors with the data via email Kurmann Nine studies investigated allodynia and hyperalgesia Bell ; Blumenthal ; Bollag ; Grigoras ; Gundes ; Ju ; Kurmann ; Lavand'homme ; Lavand'homme The heterogeneity of surgical interventions precluded any evidence synthesis.

Two RCTs investigated the risk of women in labour developing backache after epidural anaesthesia during labour as primary outcome Howell ; Loughnan , but did not meet the inclusion criteria of the main analysis. The included studies did not elicit or compare the known risk factors for the development of PPP between the experimental and control groups. We are therefore unable to comment on to what degree a difference between the groups may have introduced bias Fassoulaki This may be very different for people undergoing limb amputation; they may have suffered from prolonged and excruciating ischaemic pain prior to surgery.

We excluded 79 studies, a summary of which can be found in the Characteristics of excluded studies table. No study was excluded exclusively for lack of observer blinding. One study da Costa , also failed other inclusion criteria. As reported on 22 January , SS Reuben was accused of publishing fraudulent data. Up to 22 papers have been, or will be, retracted by the journals in which they have been published, as detailed in the retraction notice in Anesthesia and Analgesia , 20 February Shafer It appears that Reuben is not among the list of retracted manuscripts, however we have placed it in the classification pending section on the advice of Cochrane Anaesthesia, Critical and Emergency Care.

Further, 11 studies from an updated search in December are currently awaiting classification see Characteristics of studies awaiting classification. These seven studies will be assessed when they have been completed. A summary of the studies can be found in the Characteristics of ongoing studies table. The risk of bias is detailed in the risk of bias tables Characteristics of included studies , the risk of bias graph Figure 2 , and is summarized in the methodological quality summary Figure 3.

Risk of bias graph: review authors' judgements about each risk of bias item presented as percentages across all included studies. Methodological quality summary: review authors' judgements about each methodological quality item for each included study.

Study authors' responses provided additional unpublished information for some studies Can ; Fassoulaki ; Fassoulaki ; Gacio ; Gundes ; Ibarra ; Lavand'homme ; Purwar ; Senturk A general finding was that the most recently published articles overall provided much more detail on this process in their study manuscripts.

The majority of studies utilized adequate concealment of allocation, using sealed, opaque envelopes opened just prior to the regional anaesthesia intervention. We did not exclude any studies for detection bias, and only outcome assessment blinding was a prerequisite for inclusion. Some study authors reported difficulties in keeping the participants and providers blinded due to the need to adjust dosing or preoperative pain control prior to limb amputation Nikolajsen , or the obvious immediate clinical effects of regional anaesthesia, that is numbness of the affected body part Lavand'homme ; Senturk Most participants will note the obvious effects of regional anaesthesia, like motor weakness and sensory loss, and guess their allocation.

This made effective blinding of participants and practitioners almost impossible. Some reported double blinding but did not provide details Bell ; Comez ; Paxton ; Pinzur Obviously, performance bias may weaken the conclusions of our review. Our conclusions are considerably weakened by shortcomings in allocation concealment, considerable attrition and incomplete outcome data.

Six studies employed adjuvants Bollag ; Brown ; Fassoulaki ; Gacio ; Lavand'homme ; Sprung , only in the experimental group, potentially introducing bias, but this did not affect the results for the breast cancer surgery subgroup and was not pertinent for the thoracotomy subgroup. This potentially introduces bias. In four studies, there was no attrition at all Comez ; Grigoras ; ; ; Weber ; Xu This graph plots attrition versus effect size log odds ratio for studies investigating regional anaesthesia for the prevention of persistent pain after thoracotomy blue , breast surgery pink and caesarean section green.

Symbol size decreases with attrition. We contacted the authors of 37 included studies during this update, and 23 in the original systematic review for clarification of study methodology or to obtain further unpublished data.

Selective reporting was a concern regarding adverse effects. Several studies reported adverse effects as 'none', but did not detail, if patients were asked about any side effects and if so which. Where reported, information on adverse effects in the included studies was mostly anecdotal and not reported separately by group Can ; Kairaluoma ; Katz ; Lavand'homme ; Paxton ; Singh ; Weber The studies were mostly supported by funds from the department or the institution.

For those studies that described support by outside funding, we did not find any undue influence by the sponsors. A number of included studies report insufficient pain control in the immediate postoperative period, as evidenced by inconsequential differences in pain scores between groups perioperatively, or similar requirements of rescue analgesic medications between groups in the immediate postoperative period Barkhuysen ; Baudry ; Bollag ; Can ; Choi ; Fassoulaki ; Ibarra ; Ju ; Karmakar ; Katz ; Lam ; Lee ; Liu ; Loane ; McKeen ; Micha ; Purwar ; Singh ; Smaldone ; Terkawi b ; Vrooman ; Xu ; Zhou These studies are at high risk of null bias as the intervention was possibly not applied correctly or at high enough dosages for a true treatment effect in the immediate postoperative period.

This likely blunted the treatment effect at three or more months postoperatively, because poor pain control in the postoperative period is probably an important driver of persistent pain after surgery Lewis ; Gottschalk The small numbers of studies found in each subgroup precluded a formal study of publication bias by graphical analysis or the test proposed by Egger in most subgroups.

We present a funnel plot for the breast surgery subgroup Figure 5 , which is inconclusive, especially considering that it is based on only 11 studies and includes several repeated observations for some among them. We acknowledge some degree of publication bias. Some studies, which failed to demonstrate substantial benefit beyond three months, could not be included because published aggregate data were insufficient for inclusion.

In some studies we could not get the individual participant data Blumenthal ; Burney ; Chiu ; McKeen ; Pinzur , even though this did not affect any inferences we made. In spite of considerable efforts outcome data were not available for some studies, as detailed also in the table Characteristics of included studies , this potentially introduced bias in our review and may reflect underlying publication bias. There are risk factors for the development of PPP Kehlet The severe ischaemic pain prior to limb amputation may be a predictor for PPP after amputation Karanikolas Most studies did not assess risk factors or baseline pain.

A census of included participants grouped according to surgery is in Appendix 8. We presented the data in 'Summary of findings' tables Table 1 ; Table 2 ; Table 3 ; Table 4 ; Table 5 , for persistent pain after thoracotomy, breast cancer surgery, caesarean section subgroups, intravenous local anaesthetic infusion and for local infiltration to reduce the risk of persistent pain at the donor site after iliac crest bone graft harvesting.

Comparison 2 Local or regional anaesthesia for the prevention of persistent postoperative pain classical analysis , Outcome 8 PPP after hysterectomy. This analysis included a total participants from seven studies Can ; Comez ; Ju ; Katz ; Liu ; Lu ; Senturk and found an overall effect clearly favouring regional anaesthesia, with an OR of 0. Limiting the analysis only to those five studies Can ; Comez ; Ju ; Lu ; Senturk that had employed epidural anaesthesia favoured regional anaesthesia even more OR 0.

High risk of bias from missing data across a number of included studies reduced our confidence in the findings. However, the risk of detection bias was low in the included studies on PPP after thoracotomy. Cryotherapy can arguably cause neuropathy Ju ; Mustola , and is clinically different from conventional pain therapy. Liu , used continuous wound infiltration instead of the epidural analgesia employed in all the other included studies.

To perform a sensitivity analysis, we excluded Ju or Liu , or both; while this reduced I 2 , the statistical heterogeneity observed, the exclusions did not alter the inferences. In other words, the resulting change in confidence intervals are not clinically relevant.

We compared this with a classical frequentist analysis and pooled five studies on regional anaesthesia for the prevention of PPP after thoracotomy in participants with dichotomous outcomes at three months after thoracotomy Analysis 2.

This resulted in an OR 0. Excluding Liu , the only study employing wound infiltration instead of epidural analgesia, resulted in similar inferences OR 0. We pooled these same four studies Can ; Comez ; Ju ; Lu plus one more Senturk , with dichotomous pain outcomes at six months after thoracotomy including data from participants Analysis 2. This resulted in OR 0. Similarly, only one small study Katz reported outcomes at 20 months in 23 participants, showing no benefit for the intervention with an OR 1.

Chiu employed a continuous wound infusion, parasternal blocks were utilized in Dogan , while Vrooman used lidocaine patches. In our inclusive analysis of overall effect Analysis 1. The inferences were not affected whether or not we included the study on plastic surgery of the breast Bell , or the study investigating intravenous infusions of local anaesthetics Terkawi b.

As an aside, Bell randomized participants to receive local anaesthetic infiltration of one breast, while the other side was infiltrated with placebo. Absorbed systemic lidocaine might have attenuated the development of PPP on the untreated side, leading to a diminished signal. This review was not planned as a comparison of different regional anaesthesia modalities and it is problematic to make inference by a crude subgroup stratification as in Analysis 1.

Their evidence synthesis OR 0. Similarly, we pooled nine studies on regional anaesthesia for breast surgery with dichotomous pain outcomes at six months postoperatively Bell ; Fassoulaki ; Gacio ; Ibarra ; Kairaluoma ; Karmakar ; Lam ; Micha ; Terkawi b , including a total of participants Analysis 2. The result strongly favoured regional anaesthesia OR 0. For a more conservative estimate, we had included the only one of the seven studies that investigated plastic surgery of the breast Bell , which has a different pathologic mechanism of persistent pain after breast cancer surgery, and the study investigating intravenous infusion of local anaesthetics Terkawi b ; however, the inferences were the same with or without inclusion of these studies OR 0.

Finally, we present the pooled results of two studies on regional anaesthesia with dichotomous pain outcomes at 12 months after breast cancer surgery Baudry ; Kairaluoma , including participants in total Analysis 2. In Baudry , the experimental treatment failed to reduce the severity of immediate postoperative pain and the results at 12 months did not favour regional anaesthesia, with an OR of 2.

Kairaluoma , with improved immediate pain control in the experimental group, however, did strongly favour the experimental intervention, with an OR of 0. In an inclusive analysis Analysis 1. The results strongly favoured the use of regional anaesthesia for the prevention of PPP after caesarean section, with an OR of 0.

We performed an inclusive analysis Analysis 1. Neither study demonstrated a clear improvement in immediate postoperative pain control or a reduction of the risk of persistent postoperative pain. We again compared the results of our inclusive analysis with a conservative stratified analysis, where we pooled two studies after caesarean section Pfannenstiel incision , including participants with dichotomous pain outcomes at three months postoperatively Bollag ; Loane but excluding O'Neill , which had zero events in both arms Deeks Analysis 2.

Evidence synthesis resulted in an OR of 1. We did not pool one study in this analysis O'Neill , as there were no events in either arm making the OR undeterminable. We pooled three studies after caesarean section Pfannenstiel incision , including participants Bollag ; Lavand'homme ; Shahin , with dichotomous pain outcomes at six months postoperatively Analysis 2.

Their analysis resulted in an OR of 0. The interventions were clinically heterogeneous, and one must be cautious when interpreting this evidence synthesis. However, all three studies individually favoured regional anaesthesia. We decided not to include two studies in our analysis above Bamigboye ; Kindberg , because they studied chronic pelvic pain Bamigboye and dyspareunia Kindberg as their outcomes after postpartum surgical repair. These conditions are materially different from persistent postoperative pain, our primary outcome.

However, a sensitivity analysis including those two studies did not alter the inferences. We performed the inclusive analysis Analysis 1. This analysis could not include Blumenthal , which reported only continuous outcomes. The overall OR for the effect was 0. We were able to include one additional study Blumenthal , in a Bayesian analysis Appendix 6.

We could not include one study reporting no pain outcome O'Neill We described the approach separately Andreae b. We pooled four RCTs with participants with continuous Blumenthal , or dichotomous Barkhuysen ; Gundes ; Singh , pain outcomes at 3, 6 and 12 months after iliac crest bone graft harvesting in our Bayesian evidence synthesis.

Results favoured continuous infusion of the donor site with local anaesthetic after iliac crest bone graft harvesting with an OR 0. Clinical inferences were unaffected by the minor changes in effect estimates OR 0. No classical frequentist analysis was possible for the effects of local anaesthesia on PPP following iliac crest bone graft, as there were only three studies that met our inclusion criteria, one with available data at three months Gundes , one with data at 12 months Barkhuysen , and one other study with available data at 55 months postoperatively Singh Two additional studies in the iliac crest bone graft surgical subcategory met the inclusion criteria, but reported only continuous pain data Blumenthal or no pain outcome O'Neill The study at three months Gundes , included a total of 45 participants and found that perioperative wound instillation of bupivacaine decreased postoperative pain, with an OR of 0.

At almost four years postoperatively, one study with 20 participants Singh also found that wound irrigation with local anaesthetic reduced chronic pain after iliac crest bone graft, with an OR 0. However, local infiltration of bupivacaine showed no clear reduction in persistent postoperative pain in another study at 12 months Barkhuysen PPP may be different from phantom limb pain and timing of nociception may be much more important for the latter Karanikolas We did not pool these studies in Analysis 1.

We did not pool data from two studies with data at six months on laparotomy participants Analysis 1. The study on epidural anaesthesia for laparotomy for major gynaecological surgery Katz , provided insufficient evidence to reject the null hypothesis of no effect with an OR of 0.

Alternatively, differences in surgical specialties may explain this heterogeneity. We did not pool data for our inclusive analysis Analysis 1. We did not pool two studies after inguinal hernia repair, including hernias Kurmann ; Mounir , with outcome data at three months postoperatively Analysis 2.

However, Mounir used spinal anaesthesia, whereas Kurmann employed either spinal or general anaesthesia, at the request of the participant. The OR for Mounir , using spinal anaesthesia with wound infiltration was 0. In contrast, the OR of 2. Notably, Kurmann could not show a clear and precise improvement in pain in the immediate postoperative period, while pain was improved immediately postoperatively in Mounir We pooled two studies after prostatectomy that utilized regional anaesthesia with pain outcomes at three months postoperatively Brown ; Gupta , including a total of participants.

The pooled standard mean difference was inconclusive with a SMD of 0. Both studies reported outcomes at the same time point, three months after surgery , thus approach and results are the same using the inclusive or the classical analysis. We performed an inclusive analysis on the effect of the intervention on PPP in hysterectomy, pooling participants from three studies Purwar ; Sprung ; Wodlin performed across the above named time points Analysis 1.

The results remained inconclusive, with an overall mean difference of 1. We performed classical analysis Analysis 2. There were participants included in the analysis, which yielded a mean difference of 1. We performed an additional analysis of the effect of intravenous local anaesthesia on persistent pain after breast surgery Table 5 ; breast cancer surgery was the only surgical subgroup which has been studied thus far Analysis 1.

Two studies, one with outcomes at three months Grigoras , and one with outcomes at six months Terkawi b , and a total of 97 participants, were included in this evidence synthesis, demonstrating a meaningful benefit of the use of intravenous local anaesthetics in preventing persistent postsurgical pain in breast surgery OR 0.

One study on the use of regional anaesthesia for the prevention of pain after repair of pectus excavatum in children and young adults met the inclusion criteria for our review, but we were unable to include it in the primary analysis as it was the only study of its surgical subgroup Weber Due to the rare incidence of pain in this study, the effect of epidural anaesthesia on PPP was inconclusive at both three months OR 0.

We also report on a single study Paxton , that favoured local injection of bupivacaine to the vas deferens for pain after vasectomy, with an OR 0. Finally, we report on one study performed on plastic surgery of the breast Bell , excluded from the rest of the breast surgery subgroup as the nature of plastic surgery and the population studied are likely quite different. The results of this small study Bell , did not show a benefit to local infiltration of the wound in this subgroup at six months, with an OR 1.

While we explored the influence of anaesthesia modality on risk reduction afforded by regional anaesthesia in sensitivity analysis, the small number of studies precluded a formal subgroup analysis of anaesthesia technique. Only epidural anaesthesia was used for thoracotomy, limb amputation and laparotomy. For other surgical interventions, studies investigated a variety of regional anaesthesia techniques Appendix 7 , with the marked diversity especially in breast surgery possibly explaining the observed heterogeneity of effect.

We examined studies employing adjuvant therapy. Because they investigated surgeries of different body parts Fassoulaki ; Lavand'homme , we did not pool the data Data synthesis. Details are listed in Appendix Of the 63 studies identified, we pooled the data from 41 studies, enrolling a total of participants in our inclusive analysis.

Including participants in seven studies Can ; Comez ; Ju ; Katz ; Liu ; Lu ; Senturk , with outcomes between 3 and 18 months, results favoured regional anaesthesia for thoracotomy with an OR of OR of 0. For caesarean section Analysis 1. The results strongly favoured the use of regional anaesthesia for the prevention of PPP after caesarean section with an OR of 0.

The inclusive analysis of two studies Brown ; Gupta , reporting continuous outcomes for prostatectomy were inconclusive, with a SMD of 0. A subgroup comparison pooling two studies Grigoras ; Terkawi b , with 97 participants showed a statistically meaningful benefit of intravenous local anaesthetics in reducing the risk of persistent postsurgical pain after breast surgery with an OR of 0.

We included only one RCT in children and adolescents undergoing pectus excavatum repair; this study was inconclusive Weber A single study favoured local injection of bupivacaine to the vas deferens for pain after vasectomy, with an OR 0.

The results of one small study on local infiltration of the breast for plastic surgery did not show a benefit to local infiltration of the wound in this subgroup at six months, with an OR 1. For thoracotomy, evidence synthesis at three months of data from five studies Can ; Comez ; Ju ; Liu ; Lu , with a total of participants favoured epidural anaesthesia with an OR 0. Likewise, in the breast cancer surgery subgroup, statistical and clinical heterogeneity was notable for the outcomes observed at three months after surgery, but much less for outcomes observed six months after surgery, with both comparisons clearly favouring regional anaesthesia.

In the most conservative analysis limiting our analysis only to the two studies Ibarra ; Kairaluoma , using paravertebral block for breast cancer surgery at six months, evidence synthesis favoured the intervention OR 0. Also, for example after caesarean section Analysis 2. However, pooling data from three studies reporting outcomes at three months after caesarean section did not favour regional anaesthesia OR 1.

The same was true to a lesser extent after thoracotomy Analysis 2. As in our first review Andreae , we noted a pattern at the study level, in that if pain control was not improved in the immediate postoperative period, persistent postoperative pain was less likely to be improved at three, six or twelve months e. On the other hand, 'null bias' may simply reflect the clinical reality that providers with different training and skill levels provide regional anaesthesia of variable quality.

On one hand, especially in the breast surgery subgroup, as illustrated by Figure 6 , ordered by regional anaesthesia modality , local infiltration consistently failed to reduce the risk of persistent postoperative pain Baudry ; Bell , and as mentioned often failed to have an effect in the immediate postoperative period.

At first sight, this seems to contradict the finding that intravenous administration of lidocaine did reduce the risk of persistent postoperative pain in two studies Grigoras ; Terkawi b , and evidence synthesis of their data favoured intravenous lidocaine over control OR 0. We had planned to include studies that administered local anaesthetics systemically in our initial protocol Andreae , because we felt there is a physiological rationale for effect several months later Strichartz Surgical and anaesthetic complications were too sparsely and inconsistently reported for any conclusions to be drawn from the data included in this review.

Most included studies were performed in university settings. Other than this limitation, the inclusion and exclusion criteria did not limit the applicability of the results to people in the community. We deplore the dearth of paediatric studies Weber On a cautionary note, there is still insufficient evidence to extrapolate the effect of one regional anaesthesia technique to another.

For example, with our data on epidural anaesthesia for thoracotomy and on paravertebral block for breast cancer surgery, we cannot conclude that paravertebral blocks prevent PPP after thoracotomy. When we limited our evidence synthesis to almost identical regional techniques for very similar surgical interventions epidural anaesthesia for thoracotomy or paravertebral blocks for breast cancer surgery data shown in the previous version of this review Andreae , heterogeneity of effect measures was clearly reduced Figure 6.

Some may take the stance that pooling studies using different techniques, different adjuvants, even different local anaesthetic agents is never appropriate. Others may argue that such evidence synthesis is warranted and this type of clinical heterogeneity is immaterial and that effective pain control in the immediate postoperative period would be a better criterion to include or exclude studies.

We were not comfortable to base our decision to pool or not solely on the observed statistical heterogeneity, not least because lack of evidence for heterogeneity obviously constitutes no proof for homogeneity. Results of our evidence synthesis were indifferent to choosing a classical or more inclusive approach and suggested that regional anaesthesia reduces persistent postoperative pain after breast surgery, thoracotomy, caesarean section and iliac crest bone graft harvesting.

Our review compared local and regional anaesthesia to conventional pain control Appendix 1. Only one study Lavand'homme compared the effects of the localized for example wound infiltration versus the systemic for example intravenous administration of local anaesthetics on PPP Strichartz There is insufficient evidence to support or refute the notion that systemically administered local anaesthetics are equally effective in reducing the risk of persistent pain after surgery Lavand'homme ; Strichartz ; Vigneault , but there is evidence that intravenous local anaesthetics are also effective in reducing the risk of persistent pain after breast cancer surgery Analysis 1.

Outcomes were reported at three, six and 12 months, and beyond. Dichotomous outcomes were reported by most studies. While neither optimal nor comprehensive, dichotomous outcomes are meaningful and easy to understand for people, physicians, payers, politicians and the public alike; in other words, the media, congress aides and insurance administrators will find it easier to comprehend the benefit of regional anaesthesia when outcomes are expressed simply as a 'pain versus no pain' alternative.

We acknowledge that the dichotomous outcomes used in our review fall short of a comprehensive assessment of the full impact of PPP on peoples' quality of life Turk The summary statistics extracted from the included studies did not provide the detail required to differentiate between mild and severe disabling PPP six months after surgery Gewandter Mild versus severely disabling PPP may make an important difference Kehlet for the individual.

However, persistent pain after thoracotomy can decrease function even at low levels of pain Gottschalk Considering the impact of even minor pain on quality of life Gottschalk ; MacRae , we feel that the prevention of minor PPP after thoracotomy or breast cancer surgery is clinically meaningful; this is even more so after minor or benign elective interventions like caesarean section, vasectomy, lumpectomy or iliac bone graft harvesting. Similar to responder analysis, the state of the art for the evaluation of interventions for chronic pain Dworkin a , our dichotomous effect measure is also appropriate to investigate if regional anaesthesia reduces the risk of PPP.

The risk of regional anaesthesia is deemed very low Brown ; Jeng ; Neal ; Schnabel An overall assessment of the clinical usefulness of regional anaesthesia should probably be reserved for a Cochrane Review overview.

The 'Risk of bias' graph gives an overview of risk of bias in the included studies Figure 2 , detailed in the methodological quality summary Figure 3. We noted several important limitations in the quality of the evidence. The nature of the interventions made participant blinding effectively impossible.

Hence, performance bias may weaken the conclusions of our review. Several studies employed adjuvants only in the experimental group, potentially introducing bias, although this did not affect the pooled results for the breast cancer surgery subgroup and was not pertinent for the thoracotomy subgroup. Our conclusions are considerably weakened by high risk of bias due to incomplete outcome data, high risk of selection bias due to lack of allocation concealment and high risk of performance bias due to incomplete participant blinding across a number of the included studies Hewitt By pooling studies with disparate outcome reporting, we greatly increased our power, because more studies and more data are available for inferences.

Several reasons for a biased estimate are conceivable. Attrition might have a similar effect of biasing the effect estimates towards the null, simply by decreasing the sample size of available observed outcomes. This increased probability to keep people with pain in the study and to loose people who no longer have persistent pain , could lead to a spurious increase in the observed prevalence of persistent pain in the control or the treatment group and hence to false estimates of effect, even when the intervention is not as effective.

We also compared our analysis with a Bayesian hierarchical model and described the results elsewhere in more detail Andreae While we obtained similar inferences in our Bayesian model, we found the estimates of the credible intervals for the OR to change substantially with our modelling choices.

Not all outcome data were available for inclusion Figure 1 ; Results of the search ; Assessment of reporting biases ; Appendix This potentially introduced bias in our review and may reflect publication bias. A formal analysis of publication bias by using a funnel plot or the test proposed by Egger was precluded by the small numbers of studies found in most subgroups and their similar sizes.

Even though we feel that the funnel plot for breast surgery Figure 5 is inconclusive for publication bias, we acknowledge the possibility of underlying publication bias, as we were clearly unable to include data of all identified studies as detailed in Other potential sources of bias.

Our results were robust in different models used in the analysis, but are undeniably contingent on model assumptions. For several subgroups study design and reporting disparity were deemed clinically too heterogeneous for classical evidence synthesis. Additionally, though we attempted to conduct a comprehensive search, the 12 studies currently awaiting classification may be a source of potential bias.

Two previous narrative reviews were rather sceptical as to the potential of regional anaesthesia for the prevention of PPP Kehlet ; MacRae , but did not quote all the evidence analysed in this review. We are only aware of one new attempt to synthesize the evidence on regional anaesthesia for the prevention of chronic pain after surgery Terkawi a. He investigated the prevention of persistent postoperative pain after breast cancer surgery but only pooled studies employing paravertebral block.

The three available RCTs reported outcomes at disparate endpoints. The effects of intravenous lidocaine several months after surgery are remarkable and match findings from another excluded study in spine surgery Farag Another Cochrane Review on pharmacotherapy to prevent PPP in adults was published before the second included study Terkawi b became available and hence did attempt an evidence synthesis for this outcome Analysis 1.

Epidural anaesthesia should be considered for people undergoing open thoracotomy, and paravertebral block should be considered for women undergoing breast cancer surgery to reduce their risk of persistent postoperative pain PPP beyond three months after surgery.

Women in labour may benefit from regional anaesthesia e. Continous infusion of local anaesthetics after iliac crest bone graft harvesting may reduce the risk of PPP beyond three months.

Termine: Januar und 2. Februar , Beginn jeweils 19 Uhr im Neuhaussaal. Von Gabriele Ingenthron. Bach vertonte 30 der 37 Lieder Luthers. Ist Bach ohne Luther denkbar? War Bach ein Lutheraner? Already in , Johann Christoph Bach was appointed organist at St.

George's in Eisenach. The family first rented rooms in a half-timbered house in the Rittergasse 11 directly south of today's museum garden , and owned at the time by the city's forests administrator Balthasar Schneider. George's Church. He spent the first 10 years of his life at Eisenach. The family's musical tradition brought him into close contact with music and the musical profession.

His father early taught him to play string and wind instruments. George's, Bach could witness his cousin Johann Christoph Bach playing the organ, later his favourite instrument. The historical Bach House is one of the oldest residential buildings in Eisenach. It originally consisted of two buildings, of which the eastern part was built in and the western part in At around , both were joined.

In the first floor of the building, a Renaissance glass window frame and the timber panelling of the living room now decorated as Composing Studio still bear witness of the citizen status of the house's former occupants. In the wake of the 19th century's Bach renaissance instigated by Felix Mendelssohn Bartholdy and Robert Schumann , among others, devotees went on a search for memorabilia and also for the birthplace of the composer. An error in the local oral tradition which Bitter encountered can perhaps be attributed to the fact that members of the Bach family did indeed live in this house once, but only at a time long after Bach's birth.

When the Leipzig-based Bach-Gesellschaft , founded by Robert Schumann and others in for the sole purpose of editing all of Bach's works, had completed this task in , its members decided it should be reconstituted as Neue Bachgesellschaft New Bach Society to now further the popularity and practice of Bach's music.

Three 'eternal' projects were approved: the annual edition of a Bach-Jahrbuch Bach yearbook , biannual today: annual Bachfeste Bach festivals , and finally the founding of a Bach museum. As the desired location of the society's museum the School of St. Thomas at Leipzig was chosen, where Bach had lived with his family and served as cantor and music teacher for 27 years.

However, the magistrate of Leipzig decided to demolish the building in , thus thwarting the society's plans. When news reached the society's members that Bach's still undisputed birth house at Eisenach was also under threat by demolition plans, the New Bach Society decided to acquire the building on May 15, , and to open the world's first Bach museum at this site. The choir of St. Thomas, Leipzig under Cantor of St.

In , when the Eisenach hobby historian Fritz Rollberg undertook a research into the city's tax records and discovered that Johann Ambrosius Bach had paid taxes from until his death in for a different building in Eisenach, the Bach House was long established as a Bach memorial site throughout the world. Since visitors kept believing to be visiting Bach's birthplace even without the plate, it was decided in to restore it as an essential part of the building's history. Today, the historical error is explained in the museum, where one of the tax files discovered by Rollberg is on display.

An air raid on 23 November and artillery fire by the approaching U. Knut Hansston, ordered the museum to be repaired immediately, and one year later, on 22 June , the Soviet Military Administration ordered the Johann Sebastian Bach museums in Arnstadt and Eisenach to be re-opened and confirmed the appointment of Bach House Director Conrad Freyse to the post in which he had been working since Already in , the museum had expanded into the adjacent building Frauenplan From to , the buildings to the west of the Bach House were replaced by a new museum building, the historical building again underwent restoration, and the exhibition was completely modernized.

The project was financed by the Free State of Thuringia , the government of the Federal Republic of Germany and the European Union , with a grant totalling 4. A new, smaller building to the back of the Bach House garden had already been put up in , it contains a study hall for school classes and a library. The demolition of the 19th century buildings to the west of the Bach House in and was subject of heavy debate among the Eisenach citizens.

Penkhues' design had won first prize among twelve submissions in an architectural design contest to which the New Bach Society had invited in On 17 May , the museum was re-opened at the start of a festival period lasting until 27 May, the day of the th anniversary of the opening of the Bach House. At the day of the re-opening, the choir of St. Thomas at the time. Since the Bach House has been showing its exhibitions also at Berlin Cathedral. The collection of baroque musical instruments started with a gift of four instruments by the Dutch collector Paul de Wit in , and a gift of instruments by the heirs of musicologist and conductor Aloys Obrist who had killed both himself and his former lover, the opera singer Anna Sutter , in Since , five baroque keyboard instruments are demonstrated in a music performance every hour.

Since inspecting the dukedom's organs belonged to the court organist's duties, the museum conjectures that Bach must have known and played this instrument, even though there is no record of it. The exhibits include the so-called Bach spectacles long believed to have been worn by Bach, [57] and the Bach Goblet. It is still an unsolved riddle who may have been the donor of the goblet, and on what occasion Bach received it. Their furnishing is virtually unchanged since the rooms were first decorated by the Weimar Court Antiquary in with local items from around including door handles and fittings.

Since a room in between the historical living quarters and cladded in black hosts the exhibition space Bach's inner world. Thomas with his choir. Thirty-nine original prints, arranged in 'families', depict how our picture of Bach has changed through the centuries. An original Bach autograph, giving the history from its first discovery to its inclusion in the Neue Bach-Ausgabe , is on display.

It is, like most hand-written instrumental parts for Bach's cycles of cantatas, a collaborative work: the right hand side of the sheet on display chorus, recitative was written by Bach's student and nephew Johann Heinrich Bach the son of Bach's older brother Johann Christoph Bach from Ohrdruf , the upper left hand side air was written by Bach's wife Anna Magdalena Bach , and the music of the final chorale, along with all titles, subtitles, and some corrections up to the word Fine , are in the hand of Johann Sebastian Bach.

To the museum belongs a library which is open to the public during general opening hours. It has about 5, volumes, mostly on Bach and his contemporaries, musical instruments, and on musical history in general. Books can be searched by an OPAC. As the first and — for a long time — only Bach museum, the museum's mandate by the New Bach Society was to "collect everything that concerns Johann Sebastian Bach, his life and works, and his reception.

Eighty percent of all known Bach autographs were and still are in the possession of the Berlin State Library , [72] and already at the time, private collectors willing to part with what was left were demanding prices far exceeding the means of a private society. Subsequently, the collection grew by donations, notably those of Oskar von Hase and the Leipzig music publishers C. Apart from the items on display, the following are particularly noteworthy: a Thuringian Harpsichord from , [75] a harpsichord by Jacob Hartmann ca.

All real property and the collections are owned by the New Bach Society. The majority of public funds comes from the Thuringian government. Donations go into restorations and acquisitions for the museum's collection. Since the opening of the Bach House in there have been the following museum directors: [82]. There are about 60, visitors to the Bach House per year, [83] making it one of Germany's most frequented music museums and second to the Beethoven House in Bonn.

It was the first to show the composer figuratively in the form of a full statue. Its first location was on the market place in front of the portal of St. The monument was moved to its present location in front of the Bach House when the Frauenplan was redecorated in The monument's base was substantially shortened when it was moved. A relief plate depicting Saint Cecilia , the patron of church music, which was originally attached to the base, can now be seen on the stone wall behind the monument.
