硬膜外麻醉复合全麻在直肠癌手术中的麻醉效果观察

Observation on the Efficacy of Compound Epidurai-General Anesthesia in Rectal Cancer Surgery

为探讨硬膜外麻醉复合全麻对直肠癌手术患者的麻醉效果和不良反应，将65例低位直肠癌患者按照麻醉方式的不同分为观察组35例和对照组30例，对照组采用气管插管全麻，观察组采用气管插管全麻联合硬膜外麻醉，比较两组的麻醉效果、血液动力学指标变化及不良反应。结果显示，与对照组相比，观察组在麻醉诱导后、插管后即刻、切皮时、拔气管导管时的心率（HR）慢、收缩压（SBP）和舒张压（DBP）低，两组差异有统计学意义（P〈0．05）。观察组的术毕清醒时间、拔管时间、麻醉药用量、对肛门松弛的满意度显著优于对照组（P〈0．05）。观察组的不良反应发生率显著低于对照组（P〈0．05）。结果表明，硬膜外麻醉复合全麻用于直肠癌手术效果满意，患者血液动力学稳定，不良反应少。

This study was to discuss the efficacy of compound epidural-general anesthesia in patients with rectal cancer surgery and its adverse reactions. Sixty-five patients with low rectal cancer were divided into observation group （ n =35） and control group （ n =30） according to their anesthesia patterns. The control group received general anesthesia with endotracheal intubation, the observation group received compound epidural-general anesthesia on the basis of control group. Both groups were compared for anesthetic effica- cy, hemodynamic changes and adverse reactions. The results showed that compared with the control group, the observation group had a slow heart rate,SBP and DBP at the time after induction,as soon as endotra- cheal intubation finished, skin incision and tracheal extubation, and significant difference was found between the two groups（ P〈0. 05）. The observation group was superior to the control group in awakening time after surgery, extubation time, anesthetic dosage, and the satisfaction of anal relaxation （ P 〈 0.05）. The observation group has a lower incidence of adverse reaction than the control group（ P 〈0.05）. It is concluded that compound epiduraleneral anesthesia has a better efficacy in rectal cancer surgery,the patients are of stable hemodynamics and less adverse reactions
