Abstract

Background: The present study aimed at comparing the effect of ketorolac and morphine on the pain control in patients with renal colic.
Materials and Methods: The present clinical trial was performed on 272 patients with renal colic that were divided into two groups. Patients in the first and second groups intravenously received morphine at a dose of 1.0 mg/kg and ketorolac at a dose of 30 mg, respectively. Then, systolic blood pressure, diastolic blood pressure, heart rate, respiration rate (RR), and oxygen saturation percentage (SpO2) as well as patients' pain scores before and 5, 15, 30, 60, and 90 min after the intervention were recorded and evaluated.
Results: The results of this study revealed that the mean pain scores of patients before and after the intervention were not significantly different between the two groups (P > 0.05). However, patients' pain significantly relieved over time in both groups (reduce: Morphine group = 9.4 and ketorolac group = 9.09; P < 0.001). In addition, nausea, dizziness, and a decreased SpO2 in the morphine group were 5.1%, 2.9%, and 1.5%, respectively, and in the ketorolac group only dizziness was 2.2% (P > 0.05).
Conclusion: According to the results of this study, the efficacy of ketorolac in reducing patients' pain was not significantly different from that of morphine. Therefore, considering that the occurrence of complications in the ketorolac group was lower than that of the morphine group, it can be stated that ketorolac is a safer and more reliable drug than morphine in relieving pain in patients with renal colic.
