Brief Summary:
The purpose of this trial is to investigate whether sigh ventilation strategy, combining sigh breaths, low tidal volume, and moderate PEEP levels, protects against major pulmonary complications within the first 7 postoperative days after cardiac surgery, as compared with conventional ventilation strategy with low tidal volume, and moderate PEEP levels.
Detailed Description:
Preventing postoperative pulmonary complications with the use of low tidal volume ventilation is now an established consensus. However, low tidal volume promote alveolar collapse in poorly ventilated, dependent regions of the lung.
Recruitment maneuvers, typically delivered at specific intraoperative timepoints, aimed to counteract alveolar collapse promoted by low tidal volume, was found to yield transient physiological benefits. And the PROVECS trial failed to show extra benefit of recruitment maneuvers in cardiac surgery patients in terms of pulmonary complications within the first 7 postoperative days, as compared with low tidal volume ventilation.
Sigh breaths, which involves cyclic deep inflations to re-expand alveoli, potentially providing sustained benefits. The purpose of this trial is to investigate the specific role of sigh breaths for reducing pulmonary complications in cardiac surgery patients already receiving protective ventilation with low tidal volume and moderate PEEP levels.
