ObjectiveAuditory brainstem response (ABR) testing is the gold-standard procedure for hearing evaluation in pediatric patients who cannot complete a behavioral hearing test. The amount of audiological information obtained depends on the quality of the patient's sleep during the test. In this retrospective database review, we aimed to assess the amount and the characteristics of the audiological information obtained in ABR testing in pediatric patients with age-appropriate sedation.MethodsA retrospective chart review was conducted on 501 consecutive ABR sedation sessions performed between January 2014 and June 2016 at the Tel Aviv Medical Center. Oral triclofos was used for the sedation of younger patients (3–24 months) and intravenous propofol for older patients (>24 months). The dataset included 370 triclofos sessions (in 337 patients) and 131 propofol sessions (in 126 patients).ResultsNone of the children developed complications, and all were discharged on the same day of the evaluation. Among the hearing-impaired children, a mean of 10 (1.8 SD) ABR threshold measurements was obtained from propofol-sedated patients and 9.4 (2.8 SD) measurements from those sedated with triclofos (P = 0.039). The major characteristics of the hearing loss, including its degree, type, and configuration, were obtained from all propofol-sedated patients and from 95% of those sedated with triclofos.ConclusionsA comprehensive evaluation of hearing status can be obtained in ABR testing with age-appropriate sedation. An average number of ∼10 threshold measurements were obtained during ABR testing with age-appropriate sedation, thus allowing for the evaluation of the degree, type and configuration of the hearing loss.
