Peri-intubation oxygenation for Caesarean delivery: is there an optimal technique?
Peri-intubation oxygen administration to the pregnant patient during induction of general anaesthesia is critical to avoiding hypoxaemia and harm to the mother and fetus. Recent modelling comparing low-flow with high-flow nasal oxygen in simulated term pregnant women of varying body habitus, taken together with previous work, suggests that face mask preoxygenation with the use of low-flow or high-flow nasal oxygen during the period of apnoea prolongs the safe apnoea period, with the benefit varying by body habitus. Low-flow compared with high-flow nasal oxygen may be easier to combine with face mask preoxygenation and is readily available in all operating theatres, although future improvements in high-flow nasal oxygen delivery systems may improve ease of use for this indication.

End the confusion: general anaesthesia improves patient outcomes in endovascular thrombectomy.
Expert physiological and pharmacological care by anaesthetists is required in all stroke endovascular thrombectomy cases. RCTs show clinical benefits in recanalisation rates and functional recovery after endovascular thrombectomy with general anaesthesia compared with sedation. Many stroke centres will require wholesale reorganisation of stroke pathways to ensure anaesthesia services are available for all cases. Anaesthetists have an integral role in improving clinical outcomes in large vessel occlusion stroke.

In the last decades, several new and modern techniques have been developed for the continuous monitoring of vitals for patients undergoing surgery under general anesthesia. These complex methods are meant to come as an adjunct to classical monitoring protocols used in general anesthesia to increase patient safety. The main objectives of multimodal monitoring are avoiding the over- or underdosing of anesthetic drugs, adapting the concentration for the substances in use, reducing post-anesthetic complications, and increasing patient comfort. Recent studies have shown a series of benefits with significant clinical impact such as a reduced incidence of nausea and vomiting, shorter reversal times, a reduction in opioid consumption, shorter hospital stays, and an increase in patient satisfaction.
