A recent systematic review and meta-analysis by Wang and colleagues in the British Journal of Anaesthesia calls into question the concept that perioperative benzodiazepine administration is associated with development of postoperative delirium in older individuals after anaesthesia and surgery. This editorial focuses on potential bias within the systematic review and addresses major concerns surrounding benzodiazepine use in the older perioperative population.

Use of sodium-glucose transporter-2 (SGLT2) inhibitors has dramatically increased over the past decade. This medication class predisposes patients to euglycaemic diabetic ketoacidosis, particularly during times of physiologic stress, including fasting and surgery. Beyond case reports and series, a systematic description of perioperative metabolic effects of SGLT2 inhibitors is lacking. ⋯ These findings provide the first evidence that an anion gap acidosis, likely from ketoacids, develops in all patients who do not hold SGLT2 inhibitors before surgery rather than in an idiosyncratic few. If an SGLT2 inhibitor is unable to be stopped, postoperative monitoring of anion gap and serum ketones can help detect clinically significant euglycaemic diabetic ketoacidosis, particularly in those undergoing emergency surgery.

The first modern intensive care unit was established in Copenhagen 70 yr ago. This cornerstone of anaesthesia was largely based on experience gained using positive pressure ventilation to save hundreds of patients during the polio epidemic in 1952. Ventilation approaches, monitoring techniques, and pharmacological innovations have developed to such an extent that cuirass ventilation, which proved inadequate during the polio epidemic, might now have novel applications for both anaesthesia and treatment of the critically ill.
