The appropriate level of postoperative critical care for patients undergoing emergency surgery is unknown. We aimed to assess the outcomes of postoperative patients treated in the intensive care unit (ICU) and high dependency care unit (HDU) after emergency surgery. ⋯ In this national registry study, postoperative critical care in ICU was associated with lower in-hospital mortality than in HDU for patients undergoing medium-risk and high-risk emergency surgery. Further research is needed to understand the role of critical care for surgical patients.

Editorial Comment
The 'long shadow' of perioperative complications: association with increased risk of death up to 1 year after surgery.
Thirty-day mortality is widely used in medical and surgical outcomes research as a quality indicator, and as an endpoint in perioperative clinical trials. However, the validity of this metric has recently been questioned. In this issue of the British Journal of Anaesthesia, Fowler and colleagues quantify, update, and put into perspective the looming suspicion that perioperative adverse events cast a 'long shadow' of increased mortality, far beyond the 30-day time frame. Their work not only raises important questions on how we should think about, analyse, and report 'perioperative' complications and mortality, but also stresses anaesthesiologist and surgeon roles as key stakeholders in patient long-term survival.

Hypoxaemia during general anaesthesia can cause harm. Apnoeic oxygenation extends safe apnoea time, reducing risk during airway management. We hypothesised that low-flow nasal oxygenation (LFNO) would extend safe apnoea time similarly to high-flow nasal oxygenation (HFNO), whilst allowing face-mask preoxygenation and rescue. ⋯ There is likely to be clinical benefit to using LFNO, given that LFNO and HFNO extend safe apnoea time similarly, particularly when BMI ≥40 kg m-2. Additional benefits to LFNO include the facilitation of rescue face-mask ventilation and ability to monitor FE'O2 during preoxygenation.
