Multicenter Study Observational Study
Effect of perioperative blood transfusion on preoperative haemoglobin levels as a risk factor for long-term outcomes in patients undergoing major noncardiac surgery: a prospective multicentre observational study.
Preoperative anaemia and red blood cell (RBC) transfusions are associated with poorer clinical outcomes. It is unknown whether perioperative RBC transfusions mediate the relationship between preoperative haemoglobin levels and postoperative outcomes. ⋯ Preoperative haemoglobin levels were significantly associated with 1-yr MACCEs and all-cause mortality. This effect was not mediated by perioperative RBC transfusions. Further research is needed to confirm these findings.

Helping clinicians debrief themselves: a simple how-to guide.
The operating theatre is a dynamic and challenging environment where effective teamwork is essential. Routine clinical debriefings, which involve brief reflections on collaboration to identify successes and areas for improvement, have proved to enhance teamwork, particularly in the operating theatre. However, barriers such as time constraints, conflicting priorities, and a lack of standardised debriefing processes hinder their regular use. Implementation of TALK©, a voluntary self-debriefing method, showed significant improvements in debriefing performance and integration of debriefing into routine practice, although long-term consistency remains a challenge.

Environmental and financial impacts of perioperative paracetamol use: a multicentre international life-cycle analysis.
Pharmaceuticals account for 19-32% of healthcare greenhouse gas (GHG) emissions. Paracetamol is a common perioperative analgesic agent. We estimated GHG emissions associated with i.v. and oral formulations of paracetamol used in the perioperative period. ⋯ Intravenous paracetamol has 12-fold greater life-cycle carbon emissions than the oral tablet form. Glass vials have higher greenhouse gas emissions than plastic vials. Intravenous administration should be reserved for cases in which oral formulations are not feasible.

Anaesthesiologists overwhelmingly favour pulse wave analysis techniques as their primary method to monitor cardiac output during high-risk noncardiac surgery. In patients with a radial arterial catheter in place, pulse wave analysis techniques have the advantage of instantly providing non-operator-dependent and continuous haemodynamic monitoring information. ⋯ They have the advantage of minimising plastic waste and related carbon dioxide emissions, and also significantly reducing hospital costs. The future integration of pulse wave analysis algorithms into multivariable bedside monitors, obviating the need for standalone haemodynamic monitors, could lead to wider use of haemodynamic monitoring solutions by further reducing their cost and carbon footprint.
