Sachin Jain

Background: It is found that hearing loss (HL) in the early stages of life may guide to emotional, cognitive and social disorders. The present study was conducted to do electrophysiological evaluation of hearing loss in neonates. Materials & Methods: The present study was conducted on 86 infants with risk of hearing loss of both genders. The auditory brainstem response (ABR) testing was performed using the Integrity V500 equipment. Response thus obtained was recorded. Results: Out of 86 patients, boys were 46 and girls were 40. Age group 1-3 months had 36 subjects, 4-6 months had 22, 7-9 months had 20 and 10-12 months had 8 subjects. The difference was significant (P< 0.05). Risk index for hearing impairment such as family’s perception for hearing loss in 8, length of stay in NICU more than 5 days in 5, mechanical ventilation in 4, postnatal infection such as meningitis in 2, gestational events such as drug abuse in 1, use of ototoxic medication in 7, hearing loss in the family in 2, craniofacial anomalies in 1, hearing loss-associated syndrome in 5, failed the newborn hearing screening in 10 subjects. Conclusion: Authors found that hearing loss in infants is quite common among those admitted to NICU. Implementation of auditory brainstem response (ABR) testing is required. Key words: Auditory brainstem response, Children, Hearing.
