Review Meta Analysis
Impact of intravenous and topical lidocaine on clinical outcomes in patients receiving propofol for gastrointestinal endoscopic procedures: a meta-analysis of randomised controlled trials.
The efficacy of i.v. or topical lidocaine as an anaesthesia adjunct in improving clinical outcomes in patients receiving gastrointestinal endoscopic procedures under propofol sedation remains unclear. ⋯ This meta-analysis demonstrated that i.v. or topical lidocaine appears safe to use and may be of benefit for improving propofol sedation in patients undergoing gastrointestinal endoscopic procedures. Further large-scale trials are warranted to support our findings.

Randomized Controlled Trial
Intrathecal morphine does not prevent chronic postsurgical pain after elective Caesarean delivery: a randomised controlled trial.
Morphine is frequently added to spinal anaesthesia for Caesarean delivery. We aimed to determine whether intrathecal morphine for spinal anaesthesia decreases the risk of chronic postsurgical pain (CPSP). ⋯ NCT03451695.

Randomized Controlled Trial
Evaluation of intraoperative ketamine on the prevention of severe rebound pain upon cessation of peripheral nerve block: a prospective randomised, double-blind, placebo-controlled study.
Pain after resolution of peripheral nerve block, known as 'rebound pain' (RP), is a major problem in outpatient surgery. The primary objective was to evaluate the benefit of intraoperative ketamine at an anti-hyperalgesic dose on the incidence of rebound pain after upper limb surgery under axillary plexus block in ambulatory patients. The secondary objective was to better understand the rebound pain phenomenon (individual risk factors). ⋯ Ketamine at an anti-hyperalgesic dose showed no benefit on rebound pain development. Although central sensitisation might not be involved, preoperative pain intensity, and catastrophising stand as risk factors. Because rebound pain remains frequent despite adequate procedure-specific postoperative analgesia, future studies should focus on patient-specific pain management.

Clinical practice guidelines are a valuable resource aiding medical decision-making based on scientific evidence. In anaesthesia, guidelines are increasing in both number and scope, influencing individual practice and shaping local departmental policy. The aim of this review is to assess the quality of clinical practice guidelines published in high impact anaesthesia journals over the past 5 yr using the internationally validated Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. ⋯ Most guidelines studied involved international collaboration but emerged from a single professional society. Use of an appraisal tool was stated as high but poorly detailed. The improvement in the overall score of guidelines and rigour of development is promising; however, only seven guidelines met high-quality criteria, suggesting room for improvement for the overall integrity of guidelines in anaesthesia.
