Observational Study
EEG biomarkers from anesthesia induction to identify vulnerable patients at risk for postoperative delirium.
Postoperative delirium is a common complication in elderly patients undergoing anesthesia. Even though it is increasingly recognized as an important health issue, the early detection of patients at risk for postoperative delirium remains a challenge. This study aims to identify predictors of postoperative delirium by analyzing frontal electroencephalogram at propofol-induced loss of consciousness. ⋯ The findings suggest that electroencephalogram markers obtained during loss of consciousness at anesthesia induction may serve as electroencephalogram-based biomarkers to identify at an early time patients at risk of developing postoperative delirium.

Randomized Controlled Trial Multicenter Study
Association of mechanical energy and power with postoperative pulmonary complications in lung resection surgery: A post hoc analysis of randomized clinical trial data.
Mechanical power (MP), the rate of mechanical energy (ME) delivery, is a recently introduced unifying ventilator parameter consisting of tidal volume, airway pressures, and respiratory rates, which predicts pulmonary complications in several clinical contexts. However, ME has not been previously studied in the perioperative context, and neither parameter has been studied in the context of thoracic surgery utilizing one-lung ventilation. ⋯ ME and, in cases requiring longer periods of mechanical ventilation, MP were independently associated with postoperative pulmonary complications in thoracic surgery.

Ultrasound-guided pericapsular nerve group (PENG) block is an emerging regional anesthesia technique that may provide analgesia for patients undergoing total hip arthroplasties (THA). There are clinical studies comparing this fascial plane block to other established methods; however, evidence on the actual efficacy of this block for THA continues to evolve. ⋯ Our systematic review and meta-analysis suggest that PENG block provides better analgesia, measured as MME use, in the first 24 hours after THA, with no real impact on postoperative VAS scores. Despite statistical significance, the high heterogeneity across RCTs implies that PENG's benefits may not surpass the minimal clinically important difference threshold for us to recommend PENG as best practice in THA.
