Oral Analgesics Utilization for Children With Musculoskeletal Injury (OUCH Trial): An RCT.

BACKGROUND

Musculoskeletal injuries (MSK-Is) are a common and painful condition among children that remains poorly treated in the emergency department (ED). We aimed to test the efficacy of a combination of an anti-inflammatory drug with an opioid for pain management of MSK-I in children presenting to the ED.

METHODS

In this randomized, double-blinded, placebo-controlled trial, we enrolled children between 6 and 17 years presenting to the ED with an MSK-I and a pain score >29 mm on the visual analog scale (VAS). Participants were randomly assigned to oral morphine (0.2 mg/kg) + ibuprofen (10 mg/kg) (morphine + ibuprofen) or morphine (0.2 mg/kg) + placebo of ibuprofen or ibuprofen (10 mg/kg) + placebo of morphine. Primary outcome was children with VAS pain score <30 mm at 60 minutes postmedication administration.

RESULTS

A total of 501 participants were enrolled and 456 were included in primary analyses (morphine + ibuprofen = 177; morphine = 188; ibuprofen = 91). Only 29.9% (morphine + ibuprofen), 29.3% (morphine), and 33.0% (ibuprofen) of participants achieved the primary outcome ( = .81). Mean VAS pain reduction at 60 minutes were -18.7 (95% confidence interval [CI]: -21.9 to -16.6) (morphine + ibuprofen), -17.0 (95% CI: -20.0 to -13.9) (morphine), -18.6 (95% CI: -22.9 to -14.2) (ibuprofen) ( = .69). Children in the morphine + ibuprofen group ( < .001) and in the morphine group ( < .001) experienced more side effects than those in the ibuprofen group. No serious adverse event was reported.

CONCLUSIONS

Combination of morphine with ibuprofen did not provide adequate pain relief for children with MSK-I in the ED. None of the study medication provided an optimal pain management because most of children did not reach a mild pain score (NCT02064894).
