研究目的:

①比较试验组和对照组术后并发症发生有无差异。 ②通过EIT实时监测比较两组患者在经过手术和不同肺保护性通气操作后,局部肺通气情况有无差异以及记录试验组在术后再次发生肺不张的时间。 ③探究两组通气数据在经EIT处理后得到的指标“静默肺”区域(SSDs)和通气中心(COV)有无区别,是否能用于肺保护性通气的指标之一。  

Objectives of Study:

① Compare the incidence of postoperative complications between the experimental group and the control group. ② Real time monitoring of EIT was used to compare the differences in local lung ventilation between two groups of patients after surgery and different lung protective ventilation procedures, and to record the time when the experimental group experienced atelectasis again after surgery. ③ Exploring whether there is a difference in the indicators of Silent Pulmonary Regions (SSDs) and Ventilation Centers (COVs) obtained from two sets of ventilation data after EIT processing, and whether they can be used as one of the indicators for lung protective ventilation.

干预措施:

术前一天使用EIT测量仰卧位,左侧卧位,右侧卧位的通气情况,时长各1min。麻醉诱导后15min内进行术中体位下的PEEP滴定,从PEEP=12cmH2O开始,依次递减2cmH20,每个PEEP值维持2min,并在手术过程中使用滴定所得到的最佳PEEP值。手术结束到出PACU前使用EIT实时监测,若发现双肺通气不良则短暂增加VT和PEEP三次,以达到30-35 cm H2O的平台压力,肥胖者平台压达到40-50 cm H2O。在术后24-48小时内使用EIT进行随访,观察患者术后EIT通气图像,统计术后肺部并发症的发病率。

干预措施代码:

Intervention:

The day before surgery, EIT was used to measure the ventilation status in supine position, left lateral position, and right lateral position, with a duration of 1 minute each. Within 15 minutes after anesthesia induction, perform PEEP titration in the intraoperative position, starting from PEEP=12cmH2O and gradually decreasing by 2cmH2O. Each PEEP value is maintained for 2 minutes, and the optimal PEEP value obtained from titration is used during the surgery. Real time monitoring of EIT is used from the end of the surgery to the exit of the PACU. If poor ventilation is found in both lungs, VT and PEEP are briefly increased three times to achieve a plateau pressure of 30-35 cm H2O, and in obese individuals, the plateau pressure reaches 40-50 cm H2O. Follow up with EIT within 24-48 hours after surgery, observe the EIT ventilation image of patients after surgery, and count the incidence rate of postoperative pulmonary complications.

随机方法(请说明由何人用什么方法产生随机序列):

指定研究员采用电脑生成120个随机数的随机数表,研究对象按照纳入顺序依次获取一个随机数字,将随机数字从小到大排列,若研究对象对应的随机数字位于前60位,则被分到试验组,对应的随机数字位于后60位,则被分到对照组。

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

The designated researcher uses a computer-generated random number table of 120 random numbers, and the research subjects obtain a random number in order of inclusion. The random numbers are arranged in ascending order. If the corresponding random number of the research subjects is in the top 60 positions, they are assigned to the experimental group, and if the corresponding random number is in the bottom 60 positions, they are assigned to the control group.
