ASSESSMENT OF RISK FACTORS AND FOLLOW-UP OUTCOMES FOR HEARING LOSS IN HIGH-RISK NEONATES

Abstract

Objective: Hearing loss in neonates, particularly those in high-risk categories such as NICU graduates, can significantly impede speech, cognitive, and psychosocial development. Early detection and management are pivotal to mitigating these risks. Methods: A prospective observational study was conducted on 425 neonates at SDM Medical College and Hospital, utilizing Otoacoustic Emissions (OAE) for initial auditory screening. This study assessed the incidence of hearing loss in relation to neonatal risk factors, including birth weight, ABO incompatibility, and maternal health conditions. Results: A majority of the neonates (58.82%) were screened within 3-7 d post-birth. Notable risk factors impacting hearing outcomes included low birth weight, with 11.53% of neonates weighing between 1.0 and 1.50 kg. The initial failure rates in OAE screenings were low, with 2.59% failing in the right ear, 1.18% in the left, and 0.94% in both ears. Conclusion: The study underscores the efficacy of early hearing screenings in identifying potential hearing loss in neonates, especially those exposed to multiple risk factors. Continuous and comprehensive monitoring is crucial for these high-risk groups to facilitate timely and effective interventions.
