肛肠手术麻醉方法的选择与研究

The Election and Investigation of Anesthesia Methods during Anorectal Operations

目的观察鞍麻和骶麻、局麻在肛肠手术中的麻醉效果及对血流动力学的影响。方法90例肛肠手术患者分成三组,每组30例,分别采用局麻、鞍麻和骶麻。观察术中的镇痛、肌松效果,监测术前、术中的HR、MAP、SpO2变化。结果鞍麻组麻醉效果满意率明显高于骶麻、局麻组(P<0.05);而在血流动力学方面,鞍麻组和骶麻组术前、术中的HR、MAP、SpO2均无明显改变(P>0.05)。结论鞍麻在肛肠手术有比骶麻、局麻更好的优势,而且其麻醉效果确切,操作简单,局部解剖变异少,是肛肠手术的一种理想的麻醉方法。

Objective To observe the anesthesia effects and influences of hemodynamics between saddle anes-thesia and caudal anesthesia and local anesthesia during anorectal operation. Methods 90 anorectal surgery patients were divided into three groups,each group was 30 cases,undertaking saddle anesthesia and caudal anesthesia and local anesthesia. The effects of analgesia and muscle relaxation were observed. HR,MAP,and SpO2 changes were monitored before and during operating. Results Saddle anesthesia group had significant anesthesia effects than caudal anesthesia and local anesthesia group（P〈0.05）, but before and during operating, there hadn＇t significant changes in hemodynamics between three groups（P〉 0.05）. Conclusion Saddle anesthesia has significant advantages than caudal anesthesia and local anesthesia in anorectal patients,the effect is good,and easy to operate. It has less variation in local anatomical. It is really an ideal anesthesia method in anorectal operations.
