改良骶管麻醉与局部麻醉在肛门病手术中的应用比较

Modified Caudal Anesthesia vs Local Anesthesia in Anal Disease Surgery

为探讨改良骶管麻醉与局部麻醉两种麻醉方式在肛门病手术中的应用效果，将80例手术患者随机分为第一组和第二组各40例，第一组采用改良骶管麻醉，第二组采用局部麻醉。将两组术中疼痛程度、肛门括约肌松弛度、麻醉持续时间、术后尿潴留情况进行比较。结果显示，第一组在术中疼痛程度、肛门括约肌松弛度、麻醉持续时间上优于第二组，第二组在尿潴留发生率上低于第一组。结果表明，改良骶管麻醉与局部麻醉相比，在止痛效果，肛门括约肌松弛度，止痛时间上具有优越性，但尿潴留发生率高，适合肛门部疾病复杂且操作时间长的手术。局部麻醉简便易行，尿潴留发生率低，适合肛门部疾病简单，操作时间短的手术。

In order to discuss the clinical efficacy of modified caudal anesthesia and local anesthesia in anal disease surgery,80 surgical patients were randomly divided into two groups, 40 patients for each. Group I received modified caudal anesthesia and group II local anesthesia. Both groups were compared for severity of pain,anal sphincter laxity,duration of anesthesia and urinary retention. The results showed that group I was superior to group II in severity of pain,anal sphincter laxity and duration of anesthesia,group II had a lower incidence of urinary retention than group I. It is concluded that compared with local anesthesia,modi- fied caudal anesthesia is superior in analgesic effects, anal sphincter laxity, duration of analgesia, but has a higher incidence of urinary retention, therefore, it is suitable for complicated anal surgery with long opera- tive time; local anesthesia is simple to operate and has a lower incidence of urinary retention,which is used for simple anal disease surgery with short operative time.
