Investigating the effect of alveolar recruitment on the incidence of postoperative pulmonary complication in patients who undergo laparoscopic surgery

Comparing ventilation with PEEP (positive end expiratory pressure) to ventilation with PEEP and alveolar recruitment, we expect that alveolar recruitment will reduce the incidence of pulmonary complication in patients undergo laparoscopic surgery. Ventilation with only PEEP is generally not enough to reduce postoperative pulmonary complication effectively.

Inclusion Criteria:

Exclusion Criteria:

• Chronic lung disease
• Cardiovascular disease
• ASA class ≥ III
• Receiving ventilation therapy or received within 6 months
• Refusal of participation in study or failure in informed consent
