腹腔镜下先天性巨结肠根治术的麻醉处理

目的：观察全麻复合硬膜外麻对小儿腹腔镜下先天性巨结肠根治术的影响。方法：择期行腹腔镜下先天性巨结肠根治术患儿40例，采用气管内插管静脉复合全麻＋连续硬膜外麻，监测ECG、HR、MAP、SPO2、PET CO2及血气，分别于气腹前、气腹后15及40min、放气后1min、手术结束拔管前记录各监测值。结果：与气腹前比较，HR在气腹后40min、手术结束拔管前增加明显；气腹后气道峰压明显上升，有显著差异；SPO2在气腹后有下降，无明显差异；PH值在气腹后随时间延长逐渐下降，差异显著；PETCO2与PaCO2变化趋势相似，PETCO2在气腹后有非常显著的差异，PaCO2差异显著，在手术结束拔管前均降至基础值。结论：腹腔镜下先天性巨结肠根治术采用全麻复合硬膜外麻，保证患儿完全制动、镇痛完善、肌松满意，对机体生理扰乱小，并发症少。

Management of Anesthesia of Hirschsprung's Disease Radical Operation By Abdominoscope

Objective To investigate the effect of the general anesthesia combined with peridural anesthesia on hirschsprung's radical operation through children abdominoscope. Methods 40 children patients with hirschsperung were elective eradicative operated by using endotrachal intubation complex vein general anesthesia combined with continuons peridural anesthesia.ECG,HR,MAP,SPO 2,P ET CO 2 were monitored, and blood gas were recorded and analyzed before pneumoperitoneum,15 minutes and 40 minutes after pneumoperitoneum,1 minute after deflation,before decannulation at the operation termination.Results Compared with before pneumoperitoneum date,HR inereased obviously 40 minutes after pneumoperitoneum,and before decannulation at the operation termination,peak pressure in airway increased obviously after pneumoperitoneum,the difference was notable,SPO 2 decreased after pneumoperitoneum,the difference was also significant.pH decreased gradually with the time prolongation,there was obviously difference.The trend of P ET CO 2 and PaCO 2 changes were analogous,P ET CO 2 had much notable difference after pneumoperitoneum,PaCO 2 had notable difference at the operation termination,and before decannulation,it was decreased to the basic value.Conlusions Hirschsprung's Disease eradical operation using general anesthesia combined with peridural anesthesia under abdominoscope guide,can immobilize ill children completely,relieve pain perfectly,muscular relaxation satisfactory,the physical interference to body is little and less complication.
