Mechanical Ventilation Complication, Thoracic Surgery, Inflammation
Conditions
Brief summary
The purpose of this study is to determine if a recruitment maneuver combined with protective ventilatory strategy could reduce the pulmonary and systemic inflammatory responses to one-lung ventilation during thoracic surgery.
