Intraoperative Mechanical Ventilation and Postoperative Pulmonary Complications After On-pump Cardiac Surgery in High-risk Patients (VACARM)
May 19, 2023 updated by: Rennes University Hospital
Effect of IntraoperatiVe High Positive End-ExpirAtory Pressure (PEEP) With ReCruitment MAneuveRs vs Low PEEP on Major Postoperative Pulmonary Complications and Death After On-pump Cardiac Surgery in High-risk Patients: the VACARM Study
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

Detailed Description
In this randomized controlled trial, cardiac surgery patients at risk of postoperative pulmonary complications will be assigned to intraoperative ventilation with high PEEP and RM or intraoperative mechanical ventilation with low PEEP and without RM.
The primary endpoint will be a composite endpoint including major postoperative complications within the first postoperative week and death within the 28 days after surgery
