Intraoperative Mechanical Ventilation and Postoperative Pulmonary Complications After On-pump Cardiac Surgery in High-risk Patients
Sponsor: Rennes University Hospital
Summary
Controversies remain concerning the best intraoperative mechanical ventilation regimen for major cardiac surgery. While the use of intra operative low tidal volumes is now standard practice, the optimal level of positive end-expiratory pressure (PEEP) and the use of recruitment maneuvers (RM) remain controversial. The aim of this study is to compare two regimens of intraoperative mechanical ventilation on postoperative outcomes in cardiac surgery patients at risk of postoperative pulmonary complications

Conditions
Interventions
Intervention group_MRA
Tidal Volume (Vt) =6-8 mL/kg of predicted body weight (PBW), Peep=8 cmH2O, recruitment maneuvers=30cm H2O every 30 min after intubation (except during CPB), after any disconnection and at the admission in ICU. Recruitment maneuvers are performed in accordance with the surgical team an if SAP≥90 mmHg or MAP≥65 mmHg. Ventilation is maintained during CPB Vt=2.5 mL/kg, Peep= 5 cmH2O
Control group
Vt=6-8 mL/kg of PBW, Peep=5 cmH2O , No recruitment maneuvers. Ventilation maintained during CPB Vt=2.5 mL/kg, Peep= 5 cmH2O.
