This study will address whether a lung-protective mechanical ventilation strategy protects against post-operative pulmonary and extra-pulmonary complications, and shortens length of hospital stay.
Inclusion criteria:
- High or intermediate risk for postoperative pulmonary complications following abdominal surgery, according to the ARISCAT risk score (higher or equal than 26)
Exclusion criteria:
- Age < 18 years
- Body mass index > 40 kg/m2
- Laparoscopic surgery
- Previous lung surgery (any)
- Persistent hemodynamic instability, intractable shock (considered hemodynamic unsuitable for the study by the patient's managing physician)
- History of previous severe chronic obstructive pulmonary disease (COPD) (non- invasive ventilation and/or oxygen therapy at home, repeated systemic corticosteroid therapy for acute exacerbations of COPD)
- Recent immunosuppressive medication (receiving chemotherapy or radiation therapy within last 2 months)
- Severe cardiac disease (New York Heart Association class III or IV, or acute coronary syndrome, or persistent ventricular tachyarrhythmia's)
- Mechanical ventilation > than 30 minutes (e.g., in cases of general anesthesia because of surgery) within last 30 days
- Pregnancy (excluded by laboratory analysis)
- Acute lung injury or acute respiratory distress syndrome expected to require prolonged postoperative mechanical ventilation
- Neuromuscular disease (any)
- Consented for another interventional study or refusal to participate in the study
