It remains controversial whether general anaesthetic drugs contribute to perioperative neurocognitive disorders in adult patients. Preclinical studies have generated conflicting results, likely because of differing animal models, study protocols, and measured outcomes. This scoping review of preclinical studies addressed the question: 'Do general anaesthetic drugs cause cognitive deficits in adult animals that persist after the drugs have been eliminated from the brain?' ⋯ Most studies reported cognitive deficits after general anaesthesia, with age, use of volatile anaesthetic drugs, and duration of anaesthesia as risk factors. Recommendations to improve study design and guide future research are presented.

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).

International consensus recommendations support neuraxial anesthesia as the preferred anesthetic technique for total hip arthroplasty. We hypothesized that an institutional initiative to promote spinal anesthesia within a clinical pathway would result in increased use of this technique. ⋯ Implementation of a clinical pathway change to promote spinal anesthesia for total hip arthroplasty may not have been associated with increased use of spinal anesthesia, but utilization rates can vary widely. Baseline spinal anesthesia usage at our institution was higher than the USA national average, and many factors may influence choice of anesthesia technique. Patients who receive spinal anesthesia have decreased opioid requirements and pain scores postoperatively.

ReviewWhat Is New in Obstetric Anesthesia: The 2021 Gerard W. Ostheimer Lecture.
The Gerard W. Ostheimer lecture is given annually to members of the Society for Obstetric Anesthesia and Perinatology. This lecture summarizes new and emerging literature that informs the clinical practice of obstetric anesthesiologists. ⋯ Themes include maternal mortality; disparities and social determinants of health; cognitive function, mental health, and recovery; quality and safety; operations, value, and economics; clinical controversies and dogmas; epidemics and pandemics; fetal-neonatal and child health; general clinical care; basic and translational science; and the future of peripartum anesthetic care. Practice-changing evidence is presented and evaluated. A priority list for clinical updates, systems, and quality improvement initiatives is presented.

Meta AnalysisUsefulness of Analgesia Nociception Index for guiding intraoperative opioid administration: a systematic review and meta-analysis.
This study primarily aimed at investigating the efficacy of Analgesia Nociception Index (ANI) for guiding intraoperative opioid administration in patients receiving surgery under general anesthesia. ⋯ Analgesia nociception index-guided analgesia was unable to reduce intraoperative opioid administration compared to monitoring using conventional clinical parameters. Further studies are required to support our findings.
