Abstract
Background:Pain reactions are common, especially during the insertion of colonoscope through the sigmoid colon. However, the techniques of anesthesia for colonoscopy have not been established. The aim of this study is to assess the safety and efficacy of caudal anesthesia in patients undergoing colonoscopy. Methods:In a prospective, randomized trial, 192 patients received either caudal anesthesia or non-anesthesia (Control group). Caudal anesthesia was achieved by infusion or 10ml of 1 mepivacaine (1%-10ml group) or 15ml of 0.50% mepivacain (0.5%-15ml group)5 minutes before colonoscopy. Results:A significant difference was not seen in average age, sex ratio, time reaching the cecum and examination time on colonoscopy between the groups. Anesthesia level was produced from S5 to S3. Pain score in the anesthesia groups were showed a low value in significance for the control group. There were no complications of respiratory and circulatory system during and after the examination.
