组别:

个性化PEEP组

样本量:

79

Group:

iPEEP

Sample size:

干预措施:

采用压力控制通气-容量模式,Vt=6ml/PBW(predicted body weight, PBW), 呼吸比为1:2。在特伦德伦堡体位和气腹建立后,以PEEP=20cmH2O开始,然后以2cmH2O递减,在每个滴定PEEP水平下进行五个呼吸周期,找出驱动压最小的PEEP水平,以此PEEP水平完成整个手术。手术开始后每小时进行一次肺RM,手术结束后再行一次肺RM。

干预措施代码:

Intervention:

Pressure-controlled ventilation in volume mode was utilized, with a tidal volume (Vt) set at 6 ml/kg of predicted body weight (PBW), and a respiratory ratio of 1:2. Following the establishment of the Trendelenburg position and pneumoperitoneum, we initiated positive end-expiratory pressure (PEEP) titration starting at 20 cmH2O, decrementing by 2 cmH2O at each step. At each PEEP level, five breathing cycles were conducted to identify the PEEP level associated with the lowest driving pressure. The procedure was completed at this optimal PEEP level. Postoperatively, recruitment maneuvers (RM) for the lungs were performed hourly and again after surgery completion.

干预措施:

用压力控制通气-容量模式,Vt=6ml/PBW(predicted body weight, PBW), 呼吸比为1:2。气管插管后,以PEEP=5cmH2O直至手术结束,手术开始后每小时进行一次肺RM,手术结束时再进行一次肺RM。

干预措施代码:

Intervention:

Pressure-controlled ventilation in volume mode was employed, with a tidal volume (Vt) of 6 ml/kg predicted body weight (PBW) and a respiratory ratio of 1:2. Following endotracheal intubation, positive end-expiratory pressure (PEEP) was set at 5 cmH2O and maintained throughout the procedure. Recruitment maneuvers (RM) for the lungs were performed hourly postoperatively and again upon completion of the surgery.

随机方法(请说明由何人用什么方法产生随机序列):

随机分配序列由未参与研究的麻醉医生使用SPSS生成的随机化表,按照入院顺序分配随机序号。根据患者入院时间分配干预措施。

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

Random allocation sequences were assigned random serial numbers in the order of admission by an anaesthetist not involved in the study using a randomisation table generated by SPSS. Interventions were assigned according to the time of admission of the patient.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

该研究采用部分盲法,患者及数据处理者不知道患者的干预措施,但麻醉医生知道该患者的干预措施。麻醉机呼吸参数的调整由一名经验丰富的临床麻醉医生负责。数据收集由一名项目组成员不清楚分组情况下收集。研究者只有在完成所有临床观察并完成数据记录工作后才能揭盲。

Blinding:

The study employed a partially blinded design, wherein the patients and the data processors were unaware of the intervention allocation, while the anesthesiologists were informed. An experienced clinical anesthesiologist adjusted the respiratory parameters of the anesthesia machine. Data collection was performed by a project team member who was blinded to the group assignments. Unblinding occurred only after all clinical observations and data recordings were completed.
