Randomized Controlled Trial
Intrathecal morphine and sleep apnoea severity in patients undergoing hip arthroplasty: a randomised, controlled, triple-blinded trial.
Intrathecal morphine 100mcg did not increase obstructive sleep apnea severity in those undergoing hip arthroplasty under spinal anesthesia.

Randomized Controlled Trial Comparative Study
Effects of anaesthesia method and tourniquet use on recovery following total knee arthroplasty: a randomised controlled study.
Recovery after total knee arthroplasty was similar for spinal and general anaesthesia across broad post-operative indicators.

Observational Study
MicroRNA signatures of perioperative myocardial injury after elective noncardiac surgery: prospective observational mechanistic cohort study.
Elevated plasma or serum troponin, indicating perioperative myocardial injury (PMI), is common after noncardiac surgery. However, underlying mechanisms remain unclear. Acute coronary syndrome (ACS) is associated with the early appearance of circulating microRNAs, which regulate post-translational gene expression. We hypothesised that if PMI and ACS share pathophysiological mechanisms, common microRNA signatures should be evident. ⋯ Circulating microRNAs associated with cardiac ischaemia were universally elevated in patients after surgery, independent of development of myocardial injury.

We compared anaesthetists' ability to identify haemoglobin oxygen saturation (SpO2) levels using two auditory displays: one based on a standard pulse oximeter display (varying pitch plus alarm) and the other enhanced with additional sound properties (varying pitch plus tremolo and acoustic brightness) to differentiate SpO2 ranges. ⋯ The enhanced auditory display helps anaesthetists judge SpO2 levels more effectively than current auditory displays and may facilitate 'eyes-free' monitoring.
