Fluid therapy is an integral component of perioperative management. In light of emerging evidence in this area, the Perioperative Quality Initiative (POQI) convened an international multiprofessional expert meeting to generate evidence-based consensus recommendations for fluid management in patients undergoing surgery. This article provides a summary of the recommendations for perioperative fluid management of surgical patients from the preoperative period until hospital discharge and for all types of elective and emergency surgery, apart from burn injuries and head and neck surgery. ⋯ There are ongoing gaps in knowledge resulting in variation in practice and some disagreement with our consensus recommendations. Perioperative fluid management should be individualised, taking into account the type of surgery and important patient factors, including intravascular volume status and acute and chronic comorbidities. Recommendations are made for further research in perioperative fluid management to address important gaps.

Previous meta-analyses of intravenous iron supplementation for reducing red blood cell (RBC) transfusion risk after cardiac surgery were inconclusive because of limited data. This updated meta-analysis incorporates recent evidence. ⋯ CRD42024542206 (PROSPERO).

Procedural sedation is practised by a heterogeneous group of practitioners working in a wide array of settings. However, there are currently no accepted standards for the competencies a sedation practitioner should have, the content of sedation training programmes, and guidelines for credentialing. The multidisciplinary International Committee for the Advancement of Procedural Sedation sought to develop a consensus statement on the following: which competencies should medical or dental practitioners have for procedural sedation and how are they obtained, assessed, maintained, and privileged. ⋯ Following an iterative Delphi review method, final consensus was reached. Using multispeciality consensus, we defined procedural sedation competence by identifying a set of core competencies in the domains of knowledge, skills, and attitudes across physical safety, effectiveness, psychological safety, and deliberate practice. In addition, we present a standardised framework for competency-based training and credentialing of procedural sedation practitioners.

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.
