Study population: Adult patients undergoing mechanical ventilation for general anesthesia for surgery.

Brief summary: Aiming to understand the isolated impact of high PEEP in patients undergoing mechanical ventilation for general anesthesia for surgery, three appropriately sized international multicentre randomized controlled trials have been performed over recent years: the 'PROtective Ventilation using HIgh versus LOw PEEP trial (PROVHILO), the 'individualized PeRioperative Open-lung Ventilation trial' (iPROVE), and the 'Protective intraoperative ventilation with higher versus lower levels of positive end-expiratory pressure in obese patients trial' (PROBESE). These three trials had several similarities in key areas of their study protocols, inclusion and exclusion criteria, and collected data, and even the primary and secondary outcomes. Of note, the three trials combined high PEEP with recruitment manoeuvres. This allows an individual patient data meta-analysis.


Eligibility criteria: Inclusion Criteria:

- Enrolled into one of the three studies (PROVHILO, iPROVE or PROBESE) to either high PEEP or low PEEP

Primary outcomes:
measure: Incidence of postoperative pulmonary complications
timeFrame: Until day seven or hospital discharge, whichever comes first

measure: Incidence of severe postoperative pulmonary complications
timeFrame: Until day seven or hospital discharge, whichever comes first
measure: Incidence of extrapulmonary pulmonary complications
timeFrame: Until day seven or hospital discharge, whichever comes first
measure: Incidence of intraoperative complications
timeFrame: Intraoperatively
measure: Incidence of intensive care unit admission
timeFrame: Until hospital discharge, death or 100 days, whichever comes first
measure: Hospital length of stay
