Multicenter Study
Epidemiology of suspected life-threatening perioperative anaphylaxis: a cross-sectional multicentre study in China.
Perioperative anaphylaxis is relatively rare but can be life-threatening. The incidence in China is unknown and may differ from other global geographic regions. This study was therefore designed to understand the incidence of perioperative anaphylaxis in China. ⋯ ChiCTR1900025956.

Randomized Controlled Trial Multicenter Study Comparative Study
Individualised or liberal red blood cell transfusion after cardiac surgery: a randomised controlled trial.
Current practice guidelines for red blood cell (RBC) transfusion in ICUs are based on haemoglobin threshold, without consideration of oxygen delivery or consumption. We aimed to evaluate an individual physiological threshold-guided by central venous oxygen saturation ScvO2. ⋯ NCT02963883.

Multicenter Study Observational Study
Identification of myocardial injury using perioperative troponin surveillance in major noncardiac surgery and net benefit over the Revised Cardiac Risk Index.
Patients with perioperative myocardial injury are at risk of death and major adverse cardiovascular and cerebrovascular events (MACCE). The primary aim of this study was to determine optimal thresholds of preoperative and perioperative changes in high-sensitivity cardiac troponin T (hs-cTnT) to predict MACCE and mortality. ⋯ NCT03436238.
