چکیده (انگلیسی):

Hearing loss is the most common sensory disability in the world, hearing loss should be early diagnosed and treated since; it leads to speech and language disorders. Auditory brainstem response (ABR) or Auditory evoked potential (AEP) is a neurologic test done by an audiologist to measure auditory evoke potential. Different types of sedation levels are used during auditory brainstem response test. Therefore, the aim of present study was evaluation of the sedative effect of chloral hydrate during auditory brainstem response (ABR) on children with hearing problems. Randomized selection of 160 children with age ranged between 1-5 years with hearing disorders, they were divided into: Group A: Received 20 mg/Kg chloral hydrate orally. Group B: Received 20 mg/Kg chloral hydrate orally plus 0.5 mg/Kg diazepam rectally. Group C: Received 40 mg/Kg chloral hydrate orally. Group D: Received 40 mg/Kg chloral hydrate orally plus 0.5 mg/Kg diazepam rectally. Regarding ABR testing results, positive ABR test was superior in combined group compared to other groups p=0.005 whereas; negative ABR test was low in combined group compared to other groups p=0.006. At the end of ABR testing 118.52±9.88 of testing children in combined group completed the test compared to other groups p=0.0139 while; 98.21±7.22 of testing children in combined group not completed ABR test compared to other groups p=0.005.In conclusion, combined chloral hydrate plus diazepam give more significant sedative effect than chloral hydrate alone during ABR testing in children with hearing disorders.
