Abstract
Abstract
Introduction
Pain management after coronary artery bypass graft (CABG) surgery remains challenging.
Objective
This study aimed to compare the effects of Ketorolac and Paracetamol on postoperative CABG pain relief.
Method
This double-blind randomized clinical trial study was conducted in Ahvaz, Iran, from September 2018–December 2019. Two consecutive groups of 60 patients undergoing elective on-pump coronary artery bypass graft surgery.
Intervention
The patients were divided into 0.5 mg/kg of ketorolac mg/dl and 10 mg/kg of Paracetamol after surgery for pain management. Primary outcomes were: visual analog pain scale (VAS) at the time point immediately after extubation (baseline) and at 6, 12, 24 and 48 h and the total dose of morphine consumption. Secondary outcomes included the hemodynamic variables, weaning time, chest tube derange, in-hospital mortality and myocardial infarction.
Statistical analysis: The data were analyzed using SPSS version 22(SPSS, Chicago, IL). The Mann-Whitney U-test was used to compare demographic data, VAS scores, vital signs, and side effects. Repeated measurements were tested within groups using Friedman’s ANOVA and the Wilcoxon rank-sum test. Values were expressed as means ± standard deviations. Statistical significance was defined as a p-value < 0.05.
Results
Compared with baseline scores, there were significant declines in VAS scores in both groups throughout the time sequence (P< 0.05). The statistical VAS score was slightly higher in the Paracetamol group at most time points, except for the time of 6 h. However, at 24 and 48 h, the VAS score in group Paracetamol was significantly higher than in group Ketorolac. There were no significant differences between groups about hemodynamic variables.
Conclusion
The efficacy of ketorolac is comparable to that of Paracetamol in postoperative CABG pain relief.
