Group:

VC group

Sample size:

干预措施:

采用容量控制通气模式,潮气量(Tidal Volume,VT)设定为6-8 mL/kg(按理想体重计算,理想体重=身高(cm)-105),PEEP=5 cmH2O,吸呼比(I:E)=1:2,RR根据PetCO2水平调整,维持PetCO2在35-45 mmHg,气道峰压上限设置为35 cmH2O,若气道峰压超过上限,及时调整潮气量或呼吸频率

干预措施代码:

Intervention:

Volume-controlled ventilation (VCV) was adopted. The tidal volume (VT) was set at 6–8 mL/kg based on ideal body weight, which was calculated as height (cm) minus 105. PEEP was maintained at 5 cmH2O with an inspiratory-to-expiratory ratio (I:E) of 1:2. The respiratory rate (RR) was adjusted according to end-tidal carbon dioxide (PetCO2) to keep PetCO2 within 35–45 mmHg. The upper limit of peak airway pressure was set at 35 cmH2O; if peak airway pressure exceeded this limit, tidal volume or respiratory rate was adjusted promptly.

干预措施:

采用压力控制通气模式,初始压力控制水平设置为能够获得6-8 mL/kg(理想体重)潮气量的压力(一般为12-18 cmH2O),PEEP=5 cmH2O,吸呼比(I:E)=1:2,术中持续监测潮气量和PetCO2,根据监测结果微调压力控制水平,维持潮气量在6-8 mL/kg、PetCO2在35-45 mmHg,压力控制水平最高不超过30 cmH2O。

干预措施代码:

Intervention:

Pressure-controlled ventilation (PCV) was adopted. The initial pressure control level was set to the pressure that could achieve a tidal volume (VT) of 6–8 mL/kg (based on ideal body weight), generally ranging from 12 to 18 cmH2O. PEEP was set at 5 cmH2O with an inspiratory-to-expiratory ratio (I:E) of 1:2. Tidal volume and end-tidal carbon dioxide (PetCO2) were continuously monitored during the operation. The pressure control level was finely adjusted according to the monitoring results to maintain the tidal volume at 6–8 mL/kg and PetCO2 within 35–45 mmHg, with the maximum pressure control level not exceeding 30 cmH2O.

干预措施:

采用容量控制自动气流模式,设置目标潮气量为6-8 mL/kg(理想体重),PEEP=5 cmH?O,吸呼比(I:E)=1:2,压力控制水平由麻醉机自动调节,以最低气道压力达到目标潮气量,压力上限设置为30 cmH2O,术中根据PetCO2水平调整呼吸频率,维持PetCO2在35-45 mmHg。

干预措施代码:

Intervention:

Volume-controlled automatic flow ventilation (VC-AF) was adopted. The target tidal volume (VT) was set at 6–8 mL/kg based on ideal body weight. PEEP was set at 5 cmH2O with an inspiratory-to-expiratory ratio (I:E) of 1:2. The pressure control level was automatically adjusted by the anesthesia machine to achieve the target tidal volume with the lowest airway pressure, and the upper pressure limit was set at 30 cmH?O. During the operation, the respiratory rate (RR) was adjusted according to the end-tidal carbon dioxide (PetCO2) level to maintain PetCO2 within 35–45 mmHg.
