Comparison of Post Operative Analgesia with Preoperative Topical Lidocaine Gel and Lubricant gel in Hemorrhoidectomy Operation

Because of too sever pain accompanying a hemorrhoidectomy operation; this double blind clinical trial study was done for comparison of post operative analgesia in patients which used preoperative topical lidocaine jel with those that used preoprative lubricant gel.

Two group 45 patients were candidated for elective hemorrhoidectomy under general anesthesia, and they were randomly divided into two groups, one group received preoprative topical lidocaine jel and second group received preoperative lubricant gel. Then gathered data was analyzed with Chi-square and Mann-Whitney U and T-Student test by SPSS 13 software. The results were evaluated as the mean ± SD and considered statistically significant for P<0.05.

The two groups showed similar results for demographic parameters such as age, weight and sex (P>0.05). In the preoperative lidocaine jel group severity of postoperative pain was lower (P<0.05) similarly, the time of free pain period in the preoperative lidocaine jel group was longer (P<0.05).

The use of preoperative lidocaine jel in hemorrhoidectomy operation can decrease the severity of pain and can cause longer postoperative free pain period in patients.
