Comparison of the Analgesic Efficacy of Dexketoprofen Trometamol, Meperidine, and Paracetamol in Renal Colic

This study aimed to compare the effectiveness of intravenous (IV) dexketoprofen trometamol, IV meperidine, and IV paracetamol as analgesics for renal colic in patients at the Emergency Department of Erciyes University Medical School. The double-blind, randomized trial included 90 patients aged 18-65 years. Patients were divided into three groups of 30, receiving 50 mg IV dexketoprofen trometamol, 50 mg IV meperidine, or 1000 mg IV paracetamol, administered in 250 mL of saline over 15 minutes. Pain intensity was measured at 15, 30, and 60 minutes post-administration using a 100-mm visual analog scale (VAS) and a 4-point verbal rating scale (VRS). Successful treatment was defined as a 50% or greater reduction in VAS score at 30 minutes. Patients with a VAS score of 40 mm or higher at the 30th minute were given fentanyl (1 mcg/kg, intravenously) as a rescue drug.
