“…In this study, we found that most of the newborns (52.37%) were males. The findings were similar to that of Ohl et al, 10 Mishra et al, 11 Kulkarni et al, 12 Rozario et al, 13 Boo et al 14 and Chaudhari et al 15 where male predominance was observed.…”

Introduction The present study was devised to estimate the prevalence of neonatal hearing loss and document the importance of using DPOAE as a screening tool for identifying hearing loss in newborns. Materials and Methods This hospital based descriptive study was conducted from August 2018 to August 2019. A total of 928 newborn babies were included in the study. These newborn babies were subjected to hearing screening by distortion product otoacoustic emissions (DPOAE) at 24-72 hrs after birth. For pass cases, no further testing was done. For refer cases, repeat testing with DPOAE was done within 15-30 days. Newborns with refer result on repeat DPOAE testing were subjected to Brainstem evoked response audiometry (BERA) within 3 months to confirm hearing loss. Results Nine hundred and twenty eight newborn babies were screened by DPOAE. 851 newborns passed the first DPOAE hearing screening and 77 newborns gave refer result. 21 newborns were lost to follow-up. 56 newborns underwent repeat DPOAE testing and 5 newborns were referred for BERA. Amongst the 5 newborns who underwent BERA testing, one newborn was diagnosed with bilateral profound hearing loss. Hence, the prevalence of hearing loss of 1.08 per thousand newborn babies was estimated in this study. Conclusion Hearing screening of newborns using DPOAE followed by BERA in refer cases to confirm hearing loss is useful for early detection followed by timely intervention and rehabilitation.

“…Mishra et al showed that among various neonatal factors, only stages of HIE and duration of neurological symptoms more than 5 days were significantly associated with auditory evoked response abnormalities. 15 But in our study, various neonatal factors related to HIE and BERA abnormalities did not show any statistically significant difference. This may be due to small sample size.…”

“…This may be due to small sample size. Mishra et al 15 concluded that BERA abnormalities in asphyxiated neonates were transient and revert back to normal at 3 months of age. BERA does not appear to be a useful tool for early detection of neurological handicaps in asphyxiated neonates.…”

Aim: To determine risk factors of hearing impairment in high risk neonatal intensive care unit (NICU) graduates. Methods and Material:This hospital-based prospective observational study was conducted in the NICU graduates of a tertiary center of eastern India from June 2014 to May 2015. Our study population included 130 infants of which 65 were with high-risk factors (hypoxic-ischemic encephalopathy stage II and III, neonatal hyperbilirubinemia, neonatal sepsis/meningitis, and prematurity) and another 65 normal term infants, who had no adverse perinatal clinical events. Brainstem Evoked Response Audiometry (BERA) was performed by Auditory Evoked Potential Machine before one month of age. Those infants who failed to pass the test were asked for repeat testing after 3 weeks of their initial testing. Follow up of the high-risk babies was done at 1 month, 3 months, 6 months, 9 months and at one year. Factors such as birth weight, gender, days of neonatal intensive care unit (NICU) stay and effects on BERA were analyzed.Results: Out of 65 cases, 15 (23.07%) had birth asphyxia, 20 (30.76%) had hyperbilirubinemia, 10 (15.38%) cases were neonatal sepsis/ meningitis and 20 (30.76%) were of gestational age <37 weeks. On initial BERA screening, 8 (53.33%) cases of birth asphyxia, 9 (45%) cases of hyperbilirubinemia, 2 (20%) cases of sepsis/meningitis and 6 (30%) premature babies had abnormal BERA results of which 3 (4.61%) cases had persistent BERA abnormality after a period of 1 year of follow up of which 3 (4.61%) cases had persistent BERA abnormality after a period of 1 year of follow up. Out of those 3 babies, 2 had severe birth asphyxia with encephalopathy and one had gestational age <37 weeks with other risk factors. Out of 65 controls, no BERA abnormality was detected. In patients with hyperbilirubinemia who had received only one exchange transfusion, abnormal BERA was seen in 3 (23%) on initial screening whereas those who had received 2 exchange transfusion, abnormal BERA was seen in 6 (85.7%) (p=0.03). Similarly, in 15 premature babies with associated risk factors (apnea, hypoglycemia, hypocalcemia, prolonged oxygen use), abnormal BERA was seen in 5 (33.33%) and in 5 premature babies without other risk factors,1 (20%) had abnormal BERA (p=0.001) on initial screening. Conclusion:Neonates with high-risk factors should have their hearing screening done by the age of one month and confirmation by 3 months and intervention by 6 months of age.

“…The multiple screening as seen in this study reduces the likelihood of false failed screening as demonstrated by Mishra (27). Multiple screening also allows resolution of clinical conditions such as perinatal asphyxia, prematurity, hyperbilirubinaemia and presumed neonatal sepsis (28).…”

Prevalence of Hearing Impairment Among High-Risk Newborns in Ibadan, Nigeria

The burden of severe hearing impairment is increasing with two-thirds of these hearing impaired people residing in developing countries. Newborn hearing screening helps to identify early, babies who need intervention in order to prevent future disability. Neither universal nor targeted hearing screening programme is available in Nigeria.Objectives: This study was carried out to assess the prevalence of hearing impairment among high-risk newborns in UCH and the associated risk factors.Materials and Methods: Two hundred one newborns in the neonatal unit of UCH with risk factors for hearing impairment had hearing screening done using automated auditory brainstem response (AABR) at 30, 45, and 70 dB at admission and discharge, and those that failed screening at discharge were rescreened at 6 weeks post-discharge.Results: Eighty-three (41.3%) and 32 (15.9%) high-risk newborns failed at admission and discharge screening respectively, and 19 (9.5%) still failed at follow up screening. The majority of hearing loss at follow up was bilateral (94.7%) and severe (52.6%). The risk factors associated with persistent hearing loss at follow up were acute bilirubin encephalopathy (RR = 11.2, CI: 1.4–90.6), IVH (RR = 8.8, CI: 1.1–71.8), meningitis (RR = 4.8, CI: 1.01–29), recurrent apnoea (RR = 2.7, CI: 1.01–7.3), severe perinatal asphyxia NNE III (RR = 7, CI: 2.4–20.2).Conclusion: Severe and bilateral hearing impairment is a common complication among high risk newborns in UCH persisting till 6 weeks post-neonatal care. Severe perinatal asphyxia with NNE III, ABE, IVH, meningitis and administration of amikacin for more than 5 days were significant risk factors. We recommend that SCBU graduates with these risk factors should have mandatory audiologic evaluation at discharge.
