Effects of intraperitoneal bupivacaine injection in laparoscopic appendectomy in children on post-operative pain: A controlled randomized double-blinded study

Abstract

BACKGROUND: The aim of this study is to determine the effects of local anesthetics administered intraperitoneally in laparoscopic appendectomy. METHODS: Patients who underwent laparoscopic appendectomy due to acute appendicitis were enrolled in the study. The children were divided into two groups. Intraperitoneal bupivacaine injection to appendectomy site and subdiaphragmatic area was performed after resection of appendix and aspirastion of intraperitoneal reactive fluid in Group 1 while Group 2 did not receive this therapy. The children were questioned by a nurse at postoperative 1st, 6th, 12th, and 24th h. Pain scores (PS) (abdominal), abdominal wall incisional pain (IP), shoulder pain (SP), and first need for analgesics were recorded. RESULTS: One hundred and twenty children were enrolled to the study. There was no significant difference in PS values and IP values between the two groups (p>0.05). SP values at 12th and 24th h were significantly lower in Group 1 (p
