Anaesthetic procedures are complex and subject to human error. Interventions to alleviate medication errors include organised syringe storage trays, but no standardised methods for drug storage have yet been widely implemented. ⋯ Colour-coded compartmentalisation enhanced visual search efficacy of pre-loaded trays. Reduced fixations and fixation times for the loaded tray were shown for colour-coded compartmentalised trays, indicating a reduction in cognitive load. Overall, colour-coded compartmentalised trays were associated with significant performance improvements when compared with conventional trays.

Closing the gap: artificial intelligence applied to ultrasound-guided regional anaesthesia.
The role of artificial intelligence in ultrasound-guided regional anaesthesia is explored in a recent study by Bowness and colleagues, published in the British Journal of Anaesthesia. The investigators showed that non-expert ability to identify key sono-anatomical structures was improved with the assistance of proprietary artificial intelligence software. Whether such software could increase learning efficiency, and thereby patient access, to regional anaesthesia, will require further study.

Advancing our understanding of postoperative cognitive trajectories in older adults.
The use of large amounts of uniform electronic data over long periods provides a step toward understanding and ultimately shaping the perioperative cognitive trajectory of older patients. With the improvements in the quality, uniformity, and amount of data contained within the electronic health record, along with developments in machine learning and big data analysis, we can look forward to enhanced studies that will help advance clinical practice and scientific understanding of perioperative brain health, including the severe and debilitating risk of dementia.

Exosomes as perioperative therapeutics to limit organ injury.
Perioperative organ injury is a frequent and major complication for the ∼240 million people undergoing surgery worldwide annually. Ischaemic preconditioning is a powerful technique that reduces organ injury in experimental models of heart, lung, gut, brain, and kidney ischaemia-reperfusion injury. ⋯ We describe how utilising isolated pre-conditioned exosomes (secreted vesicles containing many cell-survival mediators), some of the translational hurdles of ischaemic preconditioning can be overcome. Delivery of exosomes in the perioperative period could become a promising new therapeutic strategy to prevent perioperative organ injury.
