With crewed deep space exploration on the horizon, preparation for potential astronaut health crises in space missions has become vital. Administration of anaesthesia and analgesia presents many challenges owing to constraints specific to space (physiologic and ergonomic challenges associated with microgravity) and nonspecific factors (isolation and lack of supplies). Regional anaesthesia can be the safest option; however, we hypothesised that the ergonomics of microgravity would compromise ease and accuracy of nerve blocks. ⋯ Regional anaesthesia appears feasible for experts in simulated microgravity despite the ergonomic challenges. Although our model has limitations and might not fully capture the complexities of actual space conditions, it provides a foundation for future research into anaesthesia and analgesia during deep space missions.

We lack evidence on the cumulative effectiveness of machine learning (ML)-driven interventions in perioperative settings. Therefore, we conducted a systematic review to appraise the evidence on the impact of ML-driven interventions on perioperative outcomes. ⋯ CRD42023433163 (PROSPERO).

Mitigating the systemic loss of nitrous oxide: a narrative review and data-driven practice analysis.
Given the negative health impacts of climate change, clinicians have a fundamental responsibility to take an active role in mitigating the environmental impact of their practices. Inhaled anaesthetics are potent greenhouse gases, including nitrous oxide (N2O), with their long atmospheric lifetime, high global warming potential, and ozone-depleting properties. However, few clinicians realise that losses from central N2O supply systems account for the vast majority of overall N2O consumption in healthcare. ⋯ To date, this mitigation initiative has been successfully implemented at over 25 hospitals in our system. Raising awareness of this considerable source of healthcare-specific N2O emissions empowers clinicians to spearhead facility-level engagement and action. As healthcare leaders, clinicians should advocate for decarbonisation of clinical practices and systems while ensuring high-quality patient care.
