妇科腹腔镜手术中气腹与体位对肥胖患者呼吸循环功能的影响

目的：探讨妇科腹腔镜手术中气腹和体位对肥胖患者呼吸循环功能的影响。方法：将择期行妇科腹腔镜手术者60例分为正常[体质量指数（BMI）19.1-22.9]组30例，肥胖（BMI30.0-33.8）组30例。分别在全麻气管插管后气腹前（T0）、气腹后体位（特伦德伦伯格卧位）改变前（T1）、体位改变后15min（T2）、体位改变后30min（T3）、术毕气管导管拔出后10min（T4）时点监测平均动脉压（MAP）、心率（HR）、血氧饱和度（SpO2）、肺胸顺应性（Comp）、气道阻力（Raw）、气道峰压（Pmax）、呼气末二氧化碳分压（PETCO2）。结果：两组T1、T2、T3与T0比较，MAP、HR、Raw、PETCO2、Pmax明显升高，Comp降低，差异均有统计学意义（P〈0.05，P〈0.01）；T1时肥胖组Comp低于正常组，Raw、Pmax明显高于正常组，差异有统计学意义（P〈0.05）；T2、T3时肥胖组与正常组比较，MAP、Raw、PETCO2、Pmax明显升高，Comp降低，差异均有统计学意义（P〈0.05，P〈0.01）；T4时肥胖组MAP、HR、PETCO2明显高于T0时，且明显高于正常组（P〈0.05）。结论：气腹与体位改变均使妇科腹腔镜手术患者呼吸循环功能发生改变，肥胖患者气腹后取特伦德伦伯格卧位通气功能下降更为明显。

The Influences of the Position and Pneumoperitoneum on Respiratory and Circulatory Function of the Obesity During Laparoscopic Gynecologic Surgery

Objective:To evaluate the influences of the position and pneumoperitoneum on respiratory and circulatory function of the obesity during laparoscopic gynecologic surgery.Methods:60 patients after laparoscogic gynecologic surgery were divided into 2 groups;control group:BMI<25(n=30) and obesity group:BMI>30(n=30).MAP,HR,SpO2,Comp,Raw,Pmax,PETCO2 were measured before pneumoperitoneum(PP),after PP and before changing position(conventional trendelenburg position) at 15,30 min,after PP and changing position 10 mi...
