Pain management is one of the essentials of emergency care. Renal colic secondary to urinary stone disease forms one of the most intense pain types. The present study aimed to compare the effect of intravenous ibuprofen to paracetamol in ceasing renal colic. This randomised double-blind study was composed of two intervention arms, intravenous paracetamol and intravenous ibuprofen. Study subjects were randomised to receive a single dose of either paracetamol, 1 g in 100 ml normal saline, or ibuprofen (800 mg in 100 ml normal saline) in a blinded fashion. Subjects reported pain intensity on a visual analogue scale with lines intersection multiples of ten just before the drug administration, 15 and 30 min after the study drug administration. Two hundred patients were randomised to either of two study arms: however, 97 patients in ibuprofen group and 99 patients in paracetamol groups were included into 30 minute analysis. Differences of pain improvements between two groups was 9.5 (5.4-13.7) at 15 min (p = 0.000) and 17.1 (11.9-22.5) at 30 min, those both favouring ibuprofen over paracetamol (p = 0.000). Although ten (10.1%) patients in paracetamol group needed rescue drug, there were only two (2%) patients in ibuprofen group (difference: 8%; 95% CI 0.7-16%, p = 0.02). Intravenous 800 mg ibuprofen is more effective than IV paracetamol in ceasing renal colic at 30 min. |
