Abstract

OBJECTIVE: To evaluate the safety and efficacy of intranasal diamorphine as an analgesic for use in children in accident and emergency (A&E). METHODS: A prospective, randomised clinical trial with consecutive recruitment of patients aged between 3 and 16 years with clinically suspected limb fractures. One group received 0.1 mg/kg intranasal diamorphine, and the other group received 0.2 mg/kg intramuscular morphine. At 0, 5, 10, 20, and 30 minutes pain scores, Glasgow coma score, and peripheral oxygen saturations were recorded; parental acceptability was assessed at 30 minutes. RESULTS: 58 children were recruited, with complete data collection in 51 (88%); the median summed decrease in pain score was better for intranasal diamorphine than intramuscular morphine (9 v 8), though this was not significant (P = 0.4, Mann-Whitney U test). The episode was recorded as "acceptable" in all parents whose child received intranasal diamorphine, compared with only 55% of parents in the intramuscular morphine group (P < 0.0001, Fisher's exact test). There was no incidence of decreased peripheral oxygen saturation or depression in the level of consciousness in any patient. CONCLUSIONS: Intranasal diamorphine is an effective, safe, and acceptable method of analgesia for children requiring opiates in the A & E department.
