研究组 & 干预措施
conventional
Two-lung ventilation: tidal volume = 10 ml/kg, no PEEP. One-lung ventilation: tidal volume = 10 ml/kg, no PEEP
Protective
Two-lung ventilation: tidal volume 8 ml/kg, PEEP of 5 cmH2O. One-lung ventilation: tidal volume 6 ml/kg, PEEP of 5 cmH2O.
干预措施: protective ventilation (Procedure)
Recruitment
Two-lung ventilation: tidal volume 8 ml/kg, PEEP of 5 cmH2O. One-lung ventilation: tidal volume 6 ml/kg, PEEP of 5 cmH2O. Recruitment maneuver will be applied during one-lung ventilation.
干预措施: Recruitment maneuver combined with protective ventilation (Procedure)
结局指标
主要结局
Levels of IL-8, TNFa in the bronchoalveolar lavage
时间窗: up to 20 minutes, after reexpansion of the non-dependent lung at the end of surgery
次要结局
- plasmatic concentration of inflammatory mediators IL-1, IL-6, IL-8, IL-10, TNFa(up to 20 minutes, after reexpansion of the non-dependent lung at the end of surgery)
- oxygenation(1 hour after extubation)
- Levels of IL-1, IL-6, IL-10 in the bronchoalveolar lavage(up to 20 minutes, after reexpansion of the non-dependent lung at the end of surgery)
- Chest-X ray(7 days after surgery)
