To assess deafness in term infant with birth asphyxia by otoacoustic emission and brain stem evoked response audiometry. A Prospective observational study was done at Tertiary care government hospital from 15/02/2021 to 15/10/2022.Total 130 patients were included in the study by consecutive sampling method. All the patients fulfilling the inclusion criteria during the study period were included. After explaining the aims, objectives and methods of study, written informed consent was obtained from the parents to undergo Otoacoustic Emission (OAE) and Brain Stem Evoked Response Audiometry Test (BERA). Data was entered in case record form. Collected data was analysed by appropriate statistical methods. Hearing impairment was present in eight (6.15%) asphyxiated term infants. A mild degree of hearing loss was seen in three (37.5%), a moderate degree of hearing loss was seen in four (50%), severe degree of hearing loss was seen in one (12.5%) asphyxiated term infant. In asphyxiated term infants, no significant difference in hearing loss was seen with respect to gender, Obstetrics history, and type of delivery. Significant difference in hearing loss was seen in antenatal Diabetes mellitus, hypertension, family history of SNHL and APGAR Score less than 6. Severe degree of hearing loss was seen in prolonged labour and HTN mother. Significant difference in hearing loss was seen in antenatal Diabetes mellitus, hypertension, family history of SNHL and APGAR Score less than 4 and 6 in one and five minutes respectively. Severe degree of hearing loss was seen in prolonged labour and HTN mother.
