Randomized Controlled Trial Multicenter Study
A pilot multicentre randomised controlled trial of lidocaine infusion in women undergoing breast cancer surgery.
Chronic postoperative pain is common after breast cancer surgery. Peri-operative lidocaine infusion may prevent the development of chronic postoperative pain, but a large-scale trial is required to test this hypothesis. It is unclear whether a pragmatic, multicentre trial design that is consistent with expert guidance, addresses the limitations of previous studies, and overcomes existing translational barriers is safe, effective and feasible. ⋯ Annualised enrolment approximated 50 patients per site per year, with high levels of protocol adherence and ≥ 99% capture of outcomes at 3 and 6 months. The adjusted odds ratio (95%CI) for postoperative pain at 6 months in the lidocaine arm was 0.790 (0.370-1.684). We conclude that this trial, as designed, is safe, effective and feasible in patients undergoing breast cancer surgery, and a larger-scale trial is planned.

Review Meta AnalysisEffects of Erector Spinae Plane Block on Postoperative Pain in Children Undergoing Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled trials.
The erector spinae plane block is a novel regional anesthetic technique that is gaining popularity in pediatrics. However, the efficacy of erector spinae plane block in children is unclear. The aim of the systematic review and meta-analysis was to investigate effects of erector spinae plane block on postoperative pain relief in children. ⋯ This review provides low-quality evidence that erector spinae plane block exhibits superior analgesia compared to no block in children. Due to the limited data, evidence regarding the comparison with other regional blocks remains unclear. Future large-sized and well-designed randomized controlled trials are needed.

Randomized Controlled Trial Multicenter StudyImmediate Effects of a Continuous Peripheral Nerve Block on Postamputation Phantom and Residual Limb Pain: Secondary Outcomes From a Multicenter Randomized Controlled Clinical Trial.
We recently reported that a 6-day continuous peripheral nerve block reduced established postamputation phantom pain 3 weeks after treatment ended. However, the immediate effects of perineural infusion (secondary outcomes) have yet to be reported. ⋯ This secondary analysis suggests that a continuous peripheral nerve block decreases phantom and residual limb pain during the infusion, although few improvements were again detected until day 28, 3 weeks following catheter removal.

Multicenter Study Observational Study
Opioid prescription at postoperative discharge: a retrospective observational cohort study.
Opioid misuse is now considered a major public health epidemic in North America, with substantial social and financial consequences. As well as socio-economic and commercial drivers, modifiable risk-factors that have resulted in this crisis have been identified. The purpose of this study was to identify whether, within England, modifiable drivers for persistent postoperative opioid use were present. ⋯ However, 72.9% (78/107) had no written deprescribing advice on discharge. Similarly, of patients prescribed 'when required' opioids, 59.6% (93/156) had a specified duration of their prescription and 33.3% (52/156) were given written deprescribing advice. This study has identified a pattern of poor prescribing practices, a lack of guidance and formal training at individual institutions and highlights opportunities for improvement in opioid-prescribing practices within England.
