Intraoperative mortality is now rare. In contrast, 30-day postoperative mortality remains common, with most deaths occurring during the initial hospitalisation. The legacy of anaesthesiology will be determined by our success in dealing with postoperative mortality, which is currently the major problem in perioperative medicine. Carpe diem!

There is widespread variation in how anaesthesia is provided to individual patients even for the same types of surgery. This variation exists within departments, between hospitals, and between countries. ⋯ Local and national norms, guidance, and standards, and the positive or negative roles of key opinion leaders likely all play a part. Although clinicians may disagree where the line falls between warranted and unwarranted variations, at least some of this variation is down to anaesthetist preference, not individualised patient care.

Buprenorphine is a partial agonist at the mu opioid receptor. Due to its relatively low maximum effect on respiratory depression it is considered by some to be a safe opioid. But it can produce serious respiratory depression, particularly when combined with sedatives such as benzodiazepines.

Days alive and out of hospital (DAOH) is a composite, patient-centred outcome measure describing a patient's postoperative recovery, encompassing hospitalisation and mortality. DAOH is the number of days not in hospital over a defined postoperative period; patients who die have DAOH of zero. The Standardising Endpoints in Perioperative Medicine (StEP) group recommended DAOH as a perioperative outcome. However, DAOH has never been validated in patients undergoing emergency laparotomy. Here, we validate DAOH after emergency laparotomy and establish the optimal duration of observation. ⋯ DAOH is a valid, patient-centred outcome after emergency laparotomy. We recommend its use in clinical trials, quality assurance, and quality improvement, measured at 30 days as mortality heavily skews DAOH measured at 90 days and beyond.
