Comparison of post-operative pain score with Transversus abdominis plane (TAP) block versus placebo in open appendectomy

Aim: to compare the efficacy of tap (transversus abdominis plane) block regarding pain control in patient undergoing open appendectomy. study design: randomized control trial. methods: 200 patients undergoing for open appendectomy were included and divided into two equal groups a and b by using random number table. each group comprised of 100 patients. in group a unilateral tap block was applied on the side of surgery and 20 ml.5% bupivacaine given. in group b 20 ml normal saline was given during tap block in the triangle of petit with 16g tuohy's needle. results: mean age of patients was 32.29±9.24 years with minimum and maximum age of 18 and 50 years respectively. the male to female ratio was 2.4:1. the mean nrs score 2.64±1.48 after 24 hours. the mean nrs score of placebo group patients was 3.36±1.41 and in tap group it was 1.93±1.18.
