目的:探讨小儿腹腔镜下疝内环结扎术的麻醉处理。方法:拟行腹腔镜下疝内环结扎术的患儿50例,ASAⅠ-Ⅱ级;采用安定-氯胺酮麻醉,于气腹前、气腹后5min、15min,放气腹后5min,分别测定MAP(平均动脉压)、HR、SpO_2(脉搏血氧饱和度)及动脉血气等参数的变化。结果:与气腹前相比,气腹后5min,患儿血pH、PaO_2、SaO_2、SpO_2稍有下降,而PaCO_2、MAP、HR上升(p＜0.05),至气腹后15min但尚属正常范围,放气腹后5min上述所有参数基本恢复至气腹前水平,无需任何处理。结论:小儿腹腔镜下疝内环结扎术应用安定-氯胺酮麻醉是安全可行的。
Objective: To investigate the anesthesia of pediatric laparoscopic hernia ligation. Methods: Fifty ASAⅠ-Ⅱ children undergoing laparoscopic ligation of hernia were treated with diazepam and ketamine anesthesia. Before MAP, 5 min and 15 min after pneumoperitoneum and 5 min after deflation, MAP (Mean arterial pressure), HR, SpO2 (arterial blood gas) and arterial blood gas parameters. Results: After 5 minutes of pneumoperitoneum, the blood pH, PaO_2, SaO_2, SpO_2 slightly decreased while PaCO_2, MAP, HR increased (p <0.05) and remained normal 15 minutes after pneumoperitoneum Range, 5min after deflation abdomen All the above parameters returned to the level before pneumoperitoneum, without any treatment. Conclusion: Pediatric laparoscopic hernia ligation with diazepam and ketamine anesthesia is safe and feasible.
