Review Meta Analysis
Effects of melatonin on postoperative sleep quality: a systematic review, meta-analysis, and trial sequential analysis.
Postoperative sleep disturbances are common. Although several studies have examined the effect of melatonin on postoperative sleep disturbances, the results have not reached any definitive conclusion. We sought to conduct a systematic review to compare the effects of melatonin and melatonin agonists on postoperative sleep quality with those of placebo or no treatment in adult patients who underwent surgery under general or regional anesthesia. ⋯ PROSPERO (CRD42020180167); registered 27 October 2022.

Editorial Comment Meta Analysis
There is (probably) no (meaningful) difference in (most) outcomes between 'spinal' and 'general' anaesthesia for hip fracture surgery: time to move forward.
A meta-analysis influenced by two recent large randomised controlled trials (REGAIN and RAGA) concluded that little, if any, difference in commonly measured outcomes exists between patients administered spinal or general anaesthesia for their hip fracture surgery. We explore whether there is genuinely no difference, or what the methodological problems in research might be that prevent any real difference from being observed. We also discuss the need for greater nuance in future research to determine how anaesthetists might deliver perioperative care towards improving postoperative recovery trajectories in patients following hip fracture.

It is important to reduce the hemodynamic response during tracheal intubation. We performed a systematic review and meta-analysis of the Airway Scope and Macintosh laryngoscope to determine whether they reduce the hemodynamic responses of heart rate (HR) and mean blood pressure (MBP) after tracheal intubation under general anesthesia. ⋯ Our finding suggested that the Airway Scope attenuated hemodynamic responses at 60 seconds after tracheal intubation in comparison with that of the Macintosh laryngoscope. However, the MBP sample size is small and further research is needed.

Review Meta Analysis
Depth of anaesthesia and mortality after cardiac or noncardiac surgery: a systematic review and meta-analysis of randomised controlled trials.
Recent randomised controlled trials have failed to show a benefit in mortality by using processed electroencephalography (pEEG) to guide lighter anaesthesia. We performed a meta-analysis of mortality data from randomised trials of pEEG monitoring to assess the evidence of any protective effect of pEEG-guided light anaesthesia compared with deep anaesthesia in adults aged ≥18 yr. ⋯ CRD42022285195 (PROSPERO).
