“…Studies by Sharma et al, Agrawal et al, Deorari et al, Gupta et al [4,[6][7][8], also found statistically significant correlation of BERA changes with Serum Bilirubin [25 mg. Indicating that higher the level of bilirubin there is increased risk of bilirubin toxicity but with active intervention, it is possible to reverse the changes.…”

(1) To study the BERA changes in neonates with unconjugated hyperbilirubinemia. (2) To compare the BERA changes in the neonates with unconjugated hyperbilirubinemia before and after therapy. Thirty consecutive term appropriate for gestational age (AGA) neonates presenting to NICU with total serum bilirubin requiring intervention (using the American Academy of Pediatrics guidelines) were included in the study as cases and thirty normal term AGA neonates with uneventful peri-natal period and a maximum measured serum bilirubin \12 mg/ dl in case of term baby were included as controls after obtaining informed consent. Initial BERA was done within 3-24 h of hospitalization after obtaining informed consent from parents, at the time of discharge and at 3 month followup. Machine used for recording BERA was intelligent hearing system version 3.3. In our study out of the 30 cases 10 (33.3 %) cases were found to have BERA changes in the form of absent wave forms, raised threshold, prolonged latencies or prolonged inter peak latencies. In our study, it was observed that there was statistically significant correlation (p value \ 0.005) between increasing bilirubin level and BERA changes. Correlation of the findings of this study with previous few studies indicates that BERA can be used as a useful non invasive tool to determine auditory functions in the neonate especially changes of early bilirubin toxicity.

“…However, the included studies were not population based, and hearing loss was determined on the basis of auditory brainstem responses, which frequently normalize when TSB levels decline. 11,17,18 In addition, it is difficult to compare studies that evaluated hearing loss in infants versus studies like ours, which evaluated hearing loss in childhood.…”

“…This study shows that in moderate hyper bilirubinemia (10-20mg/dl), neurotoxicity is uncommon, and did not have strong correlation with BERA abnormality. Other studies with higher bilirubin level were conducted by Jiang 10 (>20mg/dl), Sharma 11 and Agarwal, 12 also Gupta 13 (>30mg/dl), showed strong relation between the bilirubin level and BERA abnormality. Dorothy et al 14 found the sensitivity of BAEP as a screening test to be 100%, specificity of the test is 86%.…”

OBJECTIVE: Jaundice is a common finding in neonates affecting 70% of term and 80% of preterm neonates during the first week of life. So the objective of this study is to evaluate auditory and brainstem responses in hyper bilirubinemic infants and to see if there is any statistically significant increase in latencies of wave I and V waves. To initiate rehabilitative procedure as early in life as possible a screening method to detect auditory disabilities in hyper bilirubinemic infants is of great importance. So the present study is done to know the incidence of hearing loss in hyper bilirubinemic infants & to evaluate the waves I and V in those subjects. METHODS: 45 Infants with hyper bilirubinemia>12mg% & with no other risk factor who visited pediatric OPD of Bapuji Child Health Centre were evaluated using RMS EMG. EP MARK -II machine. Latencies of Waves I and V and interpeak latency of I-V were recorded. RESULTS: On one sample t-test, latency of wave I and IPL I-V were significantly increased (p-value <0.001), latency of V was prolonged which was statistically significant (p-value <0.01). Hearing impairment in the affected infants and complete deafness where none of the waves were recorded signify that it is a risk factor for deafness. CONCLUSION: Since hyper bilirubinemia is a risk factor for hearing impairment, their hearing screening by BERA at the earliest will help in their earliest initiation of rehabilitation when the brain is sensitive to the development of speech & language.
