摘　　要：术中机械通气不当会导致气道压力升高,增加肺损伤的发生率,促使术后肺部并发症的发生,以胸科手术患者最为明显。降低肺部并发症的方法较多,压力控制容量保证通气模式(Pressure Control Ventilation-Volume Guaranteed,PCV-VG)以最低压力输送目标潮气量,适合于肺部并发症的高危人群,小潮气量通气策略有助于降低气道压力,但临床试验关于PCV-VG和小潮气量通气策略能否改善预后存在一定差异。本文将对压力控制容量保证联合小潮气量通气在外科手术中的应用作探讨。Improper intraoperative mechanical ventilation will lead to increased airway pressure,increase the incidence of lung injury,and promote the occurrence of postoperative pulmonary complications,especially in patients undergoing chest surgery.Various clinical methods are used to reduce pulmonary complications.Pressure control ventilation-volume guaranteed(PCV-VG)outputs target tidal volume with the lowest pressure,especially suitable for pulmonary complications of high-risk groups.Low tidal volume ventilation strategy helps reduce airway pressure,but whether PCV-VG combined with low tidal volume ventilation strategy can improve prognosis is controversial and this is discussed below.
