Summary The erector spinae plane block is a new regional anaesthesia technique that provides truncal anaesthesia for breast surgery. This systematic review and meta‐analysis was undertaken to determine if the erector spinae plane block is effective at reducing pain scores and opioid consumption after breast surgery. This study also evaluated the outcomes of erector spinae plane blocks compared with other regional blocks. PubMed, Embase, Scopus, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were searched. We included randomised controlled trials reporting the use of the erector spinae plane block in adult breast surgery. Risk of bias was assessed with the revised Cochrane risk‐of‐bias tool. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess trial quality. Thirteen randomised controlled trials (861 patients; 418 erector spinae plane block, 215 no blocks, 228 other blocks) were included. Erector spinae plane block reduced postoperative pain compared with no block: at 0‐2 hours (mean difference (95% CI) −1.63 (−2.97 to −0.29), 6 studies, 329 patients, high‐quality evidence, I2 = 98%, p = 0.02); at 6 hours (mean difference (95% CI) −0.90 (−1.49 to −0.30), 5 studies, 250 patients, high‐quality evidence, I2 = 91%, p = 0.003); at 12 hours (mean difference (95% CI) −0.46 (−0.67 to −0.25), 5 studies, 250 patients, high‐quality evidence, I2 = 58%, p < 0.0001); and at 24 hours (mean difference (95% CI) −0.50 (−0.70 to −0.30), 6 studies, 329 patients, high‐quality evidence, I2 = 76%, p < 0.00001). Compared with no block, erector spinae plane block also showed significantly lower postoperative oral morphine equivalent requirements (mean difference (95% CI) −21.55mg (−32.57 to −10.52), 7 studies, 429 patients, high‐quality evidence, I2 = 99%, p = 0.0001). Separate analysis of studies comparing erector spinae plane block with pectoralis nerve block and paravertebral block showed that its analgesic efficacy was inferior to pectoralis nerve block and similar to paravertebral block. The incidence of pneumothorax was 2.6% in the paravertebral block group; there were no reports of complications of the other blocks. This review has shown that the erector spinae plane block is more effective at reducing postoperative opioid consumption and pain scores up to 24 hours compared with general anaesthesia alone. However, it was inferior to the pectoralis nerve block and its efficacy was similar to paravertebral block. Further evidence, preferably from properly blinded trials, is required to confirm these findings.
During the coronavirus disease 2019 (COVID-19) pandemic, Singapore implemented large-scale institutional isolation facilities to contain outbreaks among migrant workers who contracted COVID-19 but did not have the ability to self-isolate. In this article, the authors share their experience operating one of the largest of these facilities.
A systematic review of the recent scientific literature was conducted with attention to new therapies along with reports of general consensus that were analyzed. Pain research continues to be difficult and though numerous guidelines have been developed, adequate powered studies are not common. Good practice would suggest a comprehensive approach to cancer pain management taking into account the many options available and treating each patient with a personalized therapeutic program. Though there is a very low number of randomized control trials, this probably reflects the difficulty in conducting these studies in heterogeneous cancer pain patient populations in sufficient numbers to yield credible study power.
IntroductionFrail patients have decreased physiological reserves and consequently, they are unable to recover as quickly from surgery. Frailty, as an entity, is a risk factor of increased morbidity and mortality. It is also associated with a longer time to discharge. This trial is undertaken to determine if a novel prehabilitation protocol (10-day bundle of interventions—physiotherapy, nutritional supplementation and cognitive training) can reduce the postoperative length of stay of frail patients who are undergoing elective abdominal surgery, compared with standard care.Methods and analysisThis is a prospective, single-centre, randomised controlled trial with two parallel arms. 62 patients who are frail and undergoing elective abdominal surgery will be recruited and randomised to receive either a novel prehabilitation protocol or standard care. Participants will receive telephone reminders preoperatively to encourage protocol compliance. Data will be collected for up to 30 days postoperatively. The primary outcome of the trial will be the postoperative length of stay and the secondary outcomes are the postoperative complications and functional recovery during the hospital admission.Ethics and disseminationThis study has been approved by the Singapore General Hospital Institutional Review Board (CIRB Ref: 2016/2584). The study is also listed on ClinicalTrials.gov (Trial number: NCT02921932). All participants will sign an informed consent form before randomisation and translators will be made available to non-English speaking patients. The results of this study will be published in peer-reviewed journals as well as national and international conferences. The data collected will also be made available in a public data repository.Trial registration numberNCT02921932 (ClinicalTrials.gov)
