干预措施:

Interventions:

组别:

个体化 PEEP 组(D组)

样本量:

49

Group:

Individualized PEEP group (Group D)

Sample size:

干预措施:

在 CO2气腹稳定后,进行压力肺复张方法,在PCV模式下保持吸气压不变,每30秒递增PEEP 5cmH2O,直到PEEP达20cmH2O,持续30秒,完成肺复张。在两组中,如果平台压达到30 cmH2O则停止肺复张以避免气压伤。完成肺复张之后逐渐下调PEEP值,D组:使用递减法,下调PEEP过程中从20㎝H2O开始,将 PEEP 按照 20、18、16、14、12、10、8、6、4cmH2O 呈阶梯式依次递减,每个 PEEP 水平维持 10 次呼吸循环,记录最后一次呼吸循环对应的驱动压,选择最低驱动压对应的 PEEP 值,直至拔管。

干预措施代码:

Intervention:

After the CO2 pneumoperitoneum is stabilized, perform the pressure recruitment maneuver. In PCV mode, maintain the inspiratory pressure constant and incrementally increase PEEP by 5 cmH2O every 30 seconds until PEEP reaches 20 cmH2O, sustaining it for 30 seconds to complete the recruitment. In both groups, if the plateau pressure reaches 30 cmH2O, stop the recruitment maneuver to avoid barotrauma. After completing the recruitment, gradually reduce the PEEP level. For Group D: Use the decremental method, starting from 20 cmH2O and stepwise reducing PEEP in the following sequence: 20, 18, 16, 14, 12, 10, 8, 6, and 4 cmH2O. Maintain each PEEP level for 10 respiratory cycles, record the driving pressure corresponding to the last respiratory cycle, and select the PEEP value associated with the lowest driving pressure, which is maintained until extubation.

随机方法(请说明由何人用什么方法产生随机序列):

通过计算机生成的随机对照表,将研究对象分成 2 组别,比例为 1:1。随机分组信息放入信封中,该信封被密封并且不透明,并对信封进行编码。一位未参与研究的主治麻醉医生在麻醉前打开了密封的信封,并根据分组对研究对象设定指定的呼吸机模式。

Randomization Procedure (please state who generates the random number sequence and by what method):

Using a computer-generated randomization table, the study subjects were divided into two groups with a 1:1 ratio. The randomization information was placed into sealed, opaque envelopes, and each envelope was coded. A senior anesthesiologist not involved in the study opened the sealed envelope before anesthesia and set the designated ventilator mode for the subjects based on the group assignment.
