目的 探讨二氧化碳气腹对小婴儿血流动力学改变及对血气的影响。方法 用监测仪观察 10例小婴儿气腹前、气腹后 15分钟、拔管后 3 0分钟的血流动力学与血气改变。结果 气腹后血压、二氧化碳分压显著升高 ,血液 pH值显著降低 ,6例心率增快 ,拔管后 3 0分钟观察数据基本恢复正常。动脉血氧饱和度及经皮血氧饱和度在各时间点无显著差异。结论 小婴儿能耐受二氧化碳气腹进行腹腔镜手术。
Objective To investigate the effects of carbon dioxide pneumoperitoneum on hemodynamics and blood gas in infants. Methods The monitor was used to observe the changes of hemodynamics and blood gas in 10 infants before pneumoperitoneum, 15 minutes after pneumoperitoneum and 30 minutes after extubation. Results After pneumoperitoneum, blood pressure, carbon dioxide partial pressure were significantly increased, blood pH was significantly reduced, 6 cases of heart rate increased, 30 minutes after extubation observed data returned to normal. Arterial oxygen saturation and percutaneous oxygen saturation at each time point no significant difference. Conclusion Small infants can tolerate carbon dioxide pneumoperitoneum for laparoscopic surgery.
