Popis:	BACKGROUND Moderate to deep sedation is required for an auditory brainstem response test when high-intensity stimulation is used. Chloral hydrate is the most commonly used sedative, whereas intranasal dexmedetomidine is increasingly used in pediatric non-painful procedural sedations. OBJECTIVE The aim of this study was to compare the sedation success rate after oral chloral hydrate at 50 mg kg-1 and intranasal dexmedetomidine at 3 μg kg-1 plus buccal midazolam at 0.1 mg kg-1 for an auditory brainstem response test. METHODS Children who required an auditory brainstem response test were recruited and randomly assigned to receive oral chloral hydrate at 50 mg kg-1 and intranasal placebo, or intranasal dexmedetomidine at 3 μg kg-1 with buccal midazolam 0.1 mg kg-1 . The primary outcome was the rate of successful sedation for auditory brainstem response tests. RESULTS Fifty-seven out of 82 (69.5%) were successfully sedated after chloral hydrate, while 70 out of 78 (89.7%) children were successfully sedated with dexmedetomidine plus midazolam combination, with the odd ratio (95% CI) for successful sedation between dexmedetomidine plus midazolam combination and chloral hydrate estimated to be 3.84 (1.61-9.16), P = 0.002. Dexmedetomidine plus midazolam was associated with quicker onset with median onset time 15 (IQR 11.0-19.8) for dexmedetomidine plus midazolam and 20 (IQR 15.0-27.0) for chloral hydrate respectively, with difference between median (95% CI) of 5 [3-8], P
