The incidence of silent brain infarction (SBI) and perioperative neurocognitive disorders (PND) is higher in cardiac surgery. However, standard preventive strategies remain unknown due to limited evidence.
This multicentre, prospective, randomised controlled clinical trial with a 1-year follow-up includes patients undergoing elective cardiac surgery with cardiopulmonary bypass (CPB). 912 participants are randomly assigned 1:1 into either the intervention group with neuroprotective anaesthesia targets (mean arterial pressure 65–90 mm Hg, bispectral index 40–60, bilateral regional cerebral oxygen saturation ≥60%, arterial inflow temperature
The trial was approved by the Institutional Review Board/Independent Ethics Committee of Fuwai Hospital (Approval No. 2024-2445) and all participating centres. We will disseminate the trial findings in peer-reviewed journals and present the results at national or international conferences.

Sternal surgical site infections after cardiac surgery can lead to significant morbidity, mortality, and cost. The effects of negative pressure wound management and adding vancomycin as perioperative antimicrobial prophylaxis are unknown. The PICS-PREVENA pilot/vanguard trial, a 2x2 factorial, open label, cluster-randomized crossover trial with 4 periods, was conducted at two major cardiac surgery hospitals in Ontario, Canada. Sites were randomized to one of eight sequences of the four study arms (Cefazolin or Cefazolin + Vancomycin (not analyzed) and standard wound dressing or a negative pressure 3M Prevena incision management system (Prevena). Only diabetic or obese patients were eligible for the latter comparison. This trial investigated feasability including adherence to protocol of each intervention (goal: > 90% each) and loss to follow-up (goal:
