Comparison of the Effect of Ketorolac and Pethidine on Pain Control after Cesarean Section Surgery

Introduction: There are different approaches for controlling pain in patients after cesarean section, but still there is not enough to relieve the pain and satisfaction of the patients. The aim of this study was to compare the effect of ketorolac and Pethidine on pain control after cesarean section surgery in Birjand in2016-2017. Methods: In this Randomized clinical trial study, 122 pregnant women who were candidates for cesarean section were randomly assigned to two groups of Pethidine and Ketorolac after cesarean section. Four hours later, the faces pain scale and VAS were measured in both groups. The data were analyzed by SPSS software [16] using chi-square and independed sample T-test. P<0.05 was considered as the significance level. Results: 61 patients with a mean age of 29.29 ± 5.88 years in the group of Pethidine and 30.56 ± 5.61years in the ketorolac group participated. The two groups were similar in terms of age, level of education, history of previous cesarean section, and duration of surgery. The mean pain intensity 4 hours after surgery based on VAS criteria in the Pethidine group was 5.47±2.23 and 4.98 ± 2.27 in Ketorolac group [P=0.17] and based on faces pain scale was 3.75±1.20 and 3.05±1.25 [P=0.001], respectively. Conclusions: Average pain severity was lower in the ketorolac group as compared to the Pethidine group. Considering lower side effects and better analgesic effect of ketorolac and constraints of narcotic drugs like Pethidine, ketorolac can be a good alternative to post-cesarean pain control.
