【摘要】 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。更多还原

【Abstract】 Objective:To investigate the effects of epidural block with double conduit on PO₂,PaCO₂,SpO₂,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 T₁₂-L₁ 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.更多还原
