【摘要】 目的 比较全麻与全麻复合硬膜外麻醉对腹腔镜气腹后血流动力学和脉搏氧饱和度(SpO2)的影响。方法 选择60例ASAⅠ～Ⅱ级，下腹部腹腔镜手术的患者，随机分为硬膜外+全麻组(A组，30例)和全麻组(B组，30例)。记录气膜前后收缩压(SBP)、舒张压(DBP)、心率(HR)和SpO2的变化。结果 A组气腹前后各指标无显著性变化；B组SBP、DBP、HR气腹后比气腹前显著升高，SpO2显著降低，且与A组相比各指标差异有显著性。结论 全麻复合硬膜外麻醉用于腹腔镜手术比单纯全麻可提供更稳定的血流动力学和呼吸功能。

    【Abstract】 Objective To compare the influences of general anesthesia and general anesthesia combined with epidural block on hemodynamics and sphygmus oxygen saturation (SpO2) during laparoscopic operation. Methods 60 patients, ASAⅠ～Ⅱ, scheduled for laparoscopic operation, were randomly divided into general anesthesia group(A group, n=30) and general anesthesia combined with epidural block group(B group, n=30). The blood pressure (BP), heart rate (HR)and sphygmos oxygen saturation (SpO2)were recorded before and 0, 10min after pneumoperitoneum as well as 15min after deflation abdomen. Results In A group, there were no significant differences in all the items before and after pneumoperitoneum(P>0.05). In B group, the SBP, DBP, HR increased significantly and the SpO2 decreased significantly after pneumoperitoneum compared to those before pneumoperitoneum(P<0.05). Also,there were significant differences between the two groups in the items after pneumoperitoneum(P<0.05). Conclusion The combination of general and epidural anesthesia achieve more stable hemodynamics and respiratory function than general anesthesia during laparoscopic operation. ......
