اثر بلوک پری‌آنال با بوپیواکائین بر درد پس از هموروئیدکتومی

Aim and Background: One of the most common surgical procedures is hemorrhoidectomy and pain is a common problem in patients after this surgery. Therefore postoperative pain control could have a significant impact on reducing complications and increasing patients' satisfaction. In this study, the effect of perianal block with bupivacaine on declining pain after hemorrhoidectomy has been studied. Methods and Materials: This study is a double-blind clinical trial in which, patients undergoing hemorrhoidectomy were randomly divided into two groups. The study group received perianal block with bupivacaine 0/25% after surgery and the control group did not recieve any block. In order to assess postoperative pain and nausea-vomiting , VAS and VDS scales were used, respectively. In the meanwhile, the duration of postoperative analgesia and patient satisfaction were evaluated. Findings: The two groups were sigificantly different considering the mean change in pain score (based on VAS ), the average amount of pethidine recieved, the rate of post-operative nausea and vomiting (VDS) and the percentage of patient satisfaction after the surgery. (P=0.0001). Conclusions: Perianal block with bupivacaine in elective surgical hemorrhoidectomy effectively reduces postoperative pain.
