腹腔镜胆囊切除术中硬膜外双管阻滞应用的探讨

目的:探讨围手术期硬膜外双管阻滞对氧分压(PO2)、二氧化碳分压(PaCO2)、血氧饱和度(SpO2)、应激反应及并发症的影响。方法:将择期慢性结石性胆囊炎患者随机分为实验组和对照组,每组30例,实验组T8-9+T12-L1连续硬膜外阻滞下施行腹腔镜胆囊切除术(LC);对照组静吸复合气管插管全麻下施行LC,分别于术前、术中、术后观察血气的变化,应激反应程度,并发症发生率等。结果:两组患者术前、术中血气变化参数比较差异无统计学意义(P>0.05)。两组患者术后血气变化参数比较、术后应激反应程度及并发症发生率差异有统计学意义(P<0.05)。结论:双管硬膜外阻滞能达到手术要求且经济安全。

Epidural block with double conduit in laparoscopic cholecystectomy

Objective:To investigate the effects of epidural block with double conduit on PO_2,PaCO_2,SpO_2,stress reaction and complication in laparoscopic cholecystectomy.Methods:Sixty patients with chronic cholecystetis undergoing LC were randomly divided into experiment groups(30 patients under went T_(8-9) and T_(12)-L_1 epidural block with double conduitin and the other 30 patients of the control group underwent general anesthesia).Changes of gas blood analysis,stress reaction and complication were recorded before,during and after operation.Results:There was no difference in gas blood between the two groups before and during the operation(P>0.05),while there existed prominent difference between the two growps after the operation(P<0.05).Furthermore the stress reaction and complications were significantly different between the two groups during and after the operation(P<0.05).Conclusions:Epidural block with double conduit is efficient,safe and with lower cost.
