Reducing post operative pain is a common issue in surgeries. This study was to evaluate the efficacy of wound infiltration with local anesthetics in reducing postoperative pain after appendectomy. This is a double-blind, placebo-controlled, randomized clinical trial on 40 patients with non-complicated acute appendicitis. Cases received a combination of lidocaine hydrochloride and bupivacaine hydrochloride after appendectomy and before closing the wound. Controls received the same volume of saline solution. Injections were done both under the fascia of external oblique muscle and intradermal. Pain assessment was done by two pain measuring scales, VAS and NRS, in 4, 8, 12 and 24 hours after the operation. Cases and controls were the same in age, sex, and history of opium addiction. Pain peaked in the 8th hour after operation in both groups and reduced afterwards. Pain assessments showed the same pattern using the NRS and VAS measuring scales. T-test showed the pain to be significantly less in cases comparing with the controls in all time points. No significant difference was seen in the time of receiving the first analgesic after the operation but the frequency of analgesic consumption was significantly lower in controls. This study showed local anesthetic infiltration to be effective in reducing the postoperative pain in patients undergoing appendectomy which is in contrast with the previous studies. This may be due to a different infiltration technique or pain assessment in the first 24 hours after the operation.
