Pulmonary Complication, Thoracic Surgery, Inflammation
Conditions
Brief summary
The investigator will evaluate the influence of lung protective ventilation on postoperative clinical outcome in patients undergoing one-lung ventilation for pulmonary lobectomy.
Detailed description
The hypothesis is that application of low tidal volume, moderate inspired oxygen fraction (FiO2) ,intermittent alveolar recruitment and positive end-expiratory pressure (PEEP) would be more beneficial than conventional ventilation in patients.
Interventions
High tidal volume, moderate inspired oygen fraction (FiO2).
High tidal volume, high inspired oygen fraction (FiO2).
Low tidal volume, PEEP, moderate inspired oygen fraction (FiO2) and recruitment maneuver.
Low tidal volume, PEEP, High inspired oygen fraction (FiO2) and recruitment maneuver.
