Multicenter Study Clinical Trial Observational Study
Predictors for postoperative nausea and vomiting after xenon-based anaesthesia.
The incidence of post-operative nausea and vomiting is about 30% lower following xenon anesthesia compared with traditional volatile anesthesia.

Pandemic influenza presents a major threat to global health and socioeconomic well-being. Future demand for critical care may outstrip supply and force clinicians to triage patients for admission. We evaluated the Simple Triage Scoring System (STSS), Ontario Health Plan for an Influenza Epidemic (OHPIP) and PaO2 /FiO2 (P/F) ratio to determine utility in predicting need for mechanical ventilation. ⋯ The P/F ratio was a better predictor of need for mechanical ventilation than STSS. The P/F ratio is a simple and accepted determinant of hypoxaemia and should be used if secondary triaging becomes necessary during future influenza pandemics.

Wrong-site nerve blocks: 10 yr experience in a large multihospital health-care system.
Although wrong-site surgery has garnered extensive scrutiny, the incidence of wrong-site blocks remains unknown. Our study thus sought to quantify the incidence of wrong-site blocks and examine some of their associated risk factors in our multihospital health-care system. ⋯ Our study provides the first incidence data on wrong-site block in a large patient population and can help hospitals to develop policies based on these data. It is yet to be determined whether active intervention can eliminate this adverse event.

Multicenter Study
Risk scores to facilitate preoperative prediction of transfusion and large volume blood transfusion associated with adult cardiac surgery†.
The aim of this study was to develop two novel risk prediction scores for transfusion and bleeding that would be used to inform treatment decisions, quality assurance, and clinical trial design in cardiac surgery. ⋯ Two new risk scores for any RBC transfusion or LVBT among cardiac surgery patients have excellent discrimination, and could inform clinical decision making.

Multicenter Study
Variability in practice and factors predictive of total crystalloid administration during abdominal surgery: retrospective two-centre analysis.
Variation in clinical practice in the perioperative environment and intensive care unit is a major challenge facing modern medicine. The objective of the present study was to analyse intraoperative crystalloid administration practices at two academic medical centres in the USA. ⋯ Wide variability in crystalloid administration was observed both within and between individual anaesthesia providers, which might contribute to variability in surgical outcomes.
