Topical Calcium channel blockers for effective post operative analgesia for hemorrhoidectomy patients; A Randomized Control Trial at a Tertiary Care Hospital.

Objective: To compare the mean pain scores after hemorrhoidectomy in patients given topical calcium channel blocker and patients being given routine post-operative treatment only. Study Design: Randomized Controlled Trial. Setting: Surgical Department of Holy Family Hospital. Period: 7th January 2022 to 7th July 2022. Material & Methods: Patients fulfilling the inclusion criteria were divided into two groups. Group A patients will receive topical calcium channel blockers whole group B will receive conventional analgesic medications. Patients in both groups underwent open hemorrhoidectomy under saddle block anesthesia. At the end of procedure, a lignocaine gel-soaked pack was placed in rectum which was removed after 6 hours. The post-operative treatment of test group was similar in all regards except that they were given 2% diltiazem ointment to apply to perianal region twice a day. Oral stool softeners were started after NPO duration. The patients were advised to start warm sitz bath and application of 2% lignocaine gel to perianal region 12 hourly after removal of pack. The patients in both groups were compared for the degree of pain on the second post-operative day using visual analogue scale. Results: In this study, on comparison of mean pain scores after hemorrhoidectomy in patients given topical calcium channel blocker and patients being given routine post-operative treatment only shows that pain in Group-A was 5.89+0.80 and in Group-B 3.60+0.77, p value was 0.0001. Conclusion: Topical Calcium Channel Blockers are effective in managing post hemorrhoidectomy pain.
