Brief Summary:

The purpose of this international, multicentre, double-blinded randomized controlled trial is to determine if the "open lung approach" providing recruitment maneuvers and PEEP(Positive End Expiratory Pressure) during general anesthesia reduces atelectasis formation and improves respiratory function in the immediate post-operative period after major abdominal surgery.

Participating centres throughout the world will include a total of 900 adult patients undergoing general anesthesia for open abdominal surgery with high or intermediate risk for post-operative pulmonary complications. Patients are randomized and intra-operatively ventilated with either a lung protective strategy (PEEP at 12 cmH2O with recruitment maneuvers) or a conventional strategy (PEEP at maximum 2 cmH2O without recruitment maneuvers). Patients will be assessed on the first 5 post-operative days, on day of discharge and on day 90 post-operative. Primary endpoint is any post-operative pulmonary complication (see below). Secondary endpoints are post-operative extra-pulmonary complications, intra-operative mechanical ventilation related complications, unscheduled ICU (Intensive Care Unit) (re-) admission, and length of hospital stay.

Arm Intervention/treatment
Experimental: Lung protective strategy ventilation
Lung protective strategy ventilation: PEEP at 12 cmH2O, Recruitment maneuvers (after intubation, after any disconnection from the mechanical ventilator, directly before detubation)
Procedure: Lung protective strategy ventilation
Patients are randomized and intra-operatively ventilated with a lung protective strategy (PEEP at 12 cmH2O with recruitment maneuvers)
No Intervention: Conventional Strategy
  • PEEP at maximum 2 cmH2O, if possible 0 cmH2O
  • No recruitment maneuvers Patients are randomized and intra-operatively ventilated with conventional strategy (PEEP at maximum 2 cmH2O without recruitment maneuvers).



Primary Outcome Measures :
  1. Post-operative pulmonary complications (PPCs) [ Time Frame: first 5 days post-operative and on the day of discharge a final assessment is performed scoring endpoints occuring on day 6 and up. ]
    Mild respiratory failure Severe respiratory failure ALI/ARDS (Acute Lung Injury and Acute Respiratory Distress Syndrome) Suspected pulmonary infection Pulmonary infiltrate Pleural effusion Atelectasis Pneumothorax Bronchospasm Aspiration pneumonitis Cardiopulmonary edema


Secondary Outcome Measures :
  1. Post-operative extra-pulmonary complications [ Time Frame: first 5 days post-operative and on the day of discharge a final assessment is performed scoring endpoints occuring on day 6 and up ]
  2. Intra-operative mechanical ventilation related complications [ Time Frame: during the length of anesthesia, which will be an estimated 2 to 5 hours ]
  3. Unscheduled Intensive Care Unit (ICU) (re-) admission [ Time Frame: first 5 days post-operative and on the day of discharge a final assessment is performed scoring endpoints occuring on day 6 and up ]
  4. Length of hospital stay on day 90 [ Time Frame: until day 90 post-operative ]
