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.

Randomized Controlled Trial Observational Study
Validation of three nociception indices to predict immediate postoperative pain before emergence from general anaesthesia: a prospective double-blind, observational study.
Nociception monitoring devices are designed to estimate nociception during general anaesthesia. We evaluated the predictive accuracy of heart rate and three nociception indices to predict postoperative pain before emergence from general anaesthesia. ⋯ NCT05063227.

Randomized Controlled Trial
Effect of transauricular nerve stimulation on perioperative pain: a single-blind, analyser-masked, randomised controlled trial.
Activation of central autonomic pathways, including those regulating the arterial baroreflex, might reduce acute pain. We tested the hypothesis that transcutaneous auricular nerve stimulation (TAN) reduces pain after orthopaedic trauma surgery through autonomic modulation. ⋯ Bilateral TAN reduces perioperative pain through autonomic modulation. These proof-of-concept data support a non-pharmacological, generalisable approach to improve perioperative analgesia.
