Sedation for children 2 to 5 years of age undergoing auditory brainstem response and auditory steady state responses recordings

Abstract

Objective: To evaluate the feasibility, the duration and results of sedation by intrarectal pentobarbital and oral alimemazine for auditory brain stem responses (ABR) and auditory steady-state responses (ASSR) recordings in children aged 2 to 5 years. Design: Prospective study. Study sample: 180 consecutive children aged 2 to 5 years, referred for language retardation and/or behavioral problems, who could not be tested by behavioral methods, underwent ABR and ASSR recordings. The children who did not spontaneously nap were sedated by intrarectal pentobarbital eventually potentiated by oral alimemazine. Results: A spontaneous nap was obtained in only 23 cases, 72 children received only pentobarbital, and 85 received both pentobarbital and alimemazine. Even so, recording was impossible in 16 cases, and interrupted before completion of the ASSR recordings in 45 cases. Children went to sleep in average 64 min +/− 40. The average recording time for the ABR was 20 minutes, and for the ASSR 25 minutes. Conclusion: Sedation by pentobarbital, eventually completed by oral alimemazine, allows ABR and/or ASSR recordings in 89.8% of the children who did not nap in the recording room, and is therefore a good alternative to general anesthesia in these children.
