Retrospective Comparison of Intranasal Dexmedetomidine and Oral Chloral Hydrate for Sedated Auditory Brainstem Response Exams.
Satisfactory conditions for auditory brainstem responses (ABR) screening tests for pediatric hearing loss are usually achieved with oral chloral hydrate (CH) sedation. When the US manufacture of this drug was discontinued for business reasons, we developed an alternative sedation regimen using intranasal dexmedetomidine (IN DEX) 4 μg/kg. This institutional review board-approved retrospective study compared the efficacy and adverse effect profiles of these 2 sedative regimens. ⋯ This retrospective study found that IN DEX provides effective sedation for ABR examinations, with the benefits of an ability to begin the test sooner and complete the examination with a single dose, in addition to a decreased incidence of hypoxemia. A randomized controlled trial should test the hypothesis that the IN DEX technique is superior to the well-established standard oral CH regimen.
