二氧化碳气腹对小儿呼吸和循环的影响

Effect of carbon dioxide pneumoperitomeum on children's respiration and circulation

目的 :探讨小儿腹腔镜手术时二氧化碳气腹对其呼吸和循环的影响。方法 :选择小儿腹腔镜手术的患儿分成婴儿组 (A组 )和幼儿组 (B组 ) ,选择开腹手术患儿作为对照组 (C组 ) ,连续监测记录围手术期心率 (HR)、血氧饱和度 (SpO2 )、血压 (SBP/DBP)、血气分析结果 (pH、PaCO2、PaO2 、SpO2 )。结果 :A组、B组气腹后 2 0minSBP/DBP、PaCO2 明显高于气腹前 ,(P <0 0 5 ) ,气腹后 6 0minpH值明显高于气腹前 (P <0 0 5 )。A组气腹后 2 0min与C组插管后 4 5min相比SBP/DBP、PaCO2 、pH值差异均有统计学意义 (P <0 0 5 )。结论

Objective:To investigate the effect of carbon dioxide pneumoperitoneum on respiration and circulation during pediatric laparoscopy.Methods:According to the age,24children with pediatric laparoscopy were divided into grope A(0～1 years) and group B(1～3 years),meanwhile 12 children with laparotomy as control group.The HR,SBP/DBP and SpO 2 were recoreded continuously in each patient and the arterial blood gas analysis was performed at planned period.Results:20 minutes after the establishment of pneumoperitoneum,the SBP/DBP and PaCO 2 of group A and group B were increased significantly than the pre-pneumoperitoneum(P<0.05).20 minutes after the establishment of pneumoperitoneum,the SBP/DBP,PaCO 2 and pH of group A were different significantly with 45 minutes after intracheal intubation in group C(P<0.05).Conclusion:Carbon dioxide pneumoperitoneum has different effect on children's respiration and circulation.
