Systems, safety, and anaesthesia outside the operating room.
An increasing number of patients are receiving sedation or anaesthesia in locations outside of the operating room. Compared with the operating room, anaesthesia providers working in a non-operating room anaesthesia (NORA) location report significantly lower perceived levels of safety, and higher levels of anxiety, stress, and workload. These results are likely to affect the well-being of staff in NORA locations and are clinically relevant in terms of patient safety.

A recent ex vivo study found that post-cardiopulmonary bypass platelet defects can be restored with supplemental fibrinogen, but the clinical significance of this finding will require further study. We propose that the best management strategy for achieving haemostasis in bleeding surgical patients is to identify individualised coagulation defects and then use a targeted therapeutic approach that addresses each identified defect systematically.

Shaw and colleagues, who are medical historians, have published a detailed review of the social history of the British Journal of Anaesthesia (BJA) to celebrate its first 100 years. In this editorial, we note some additional contributions and financial details that are relevant to the development of the BJA into the international high-impact journal it is today.

Sleep loss and its associated conditions (e.g. cognitive deficits) represent a large societal burden, but the underlying mechanisms of these cognitive deficits remain unknown. This study assessed the effect of dexmedetomidine (DEX) on cognitive decline induced by sleep loss. ⋯ The results demonstrate that complement pathway activation associated with synapse elimination contributes to sleep loss-related cognitive deficits and that dexmedetomidine protects against sleep deprivation-induced complement activation. Dexmedetomidine holds potential for preventing cognitive deficits associated with sleep loss, which warrants further study.

Effects of propofol and sevoflurane on social and anxiety-related behaviours in sleep-deprived rats.
Sleep disorders can profoundly affect neurological function. We investigated changes in social and anxiety-related brain functional connectivity induced by sleep deprivation, and the potential therapeutic effects of the general anaesthetics propofol and sevoflurane in rats. ⋯ Unlike sevoflurane, propofol reduced sleep deprivation-induced social and anxiety-related behaviours. Propofol might be superior to sevoflurane for patients with sleep disorders who receive anaesthesia, which should be studied in clinical studies.
