[Incidence of hearing abnormality in neonate hospitalized in neonate intensive care unit]

ABSTRACT

Risk factors including asphyxia, meningitis, form of delivery, etc may cause hearing loss in neonates results in speech and language deprivation, emotional and educational problems. The aim of this study was to determine the prevalence of hearing loss and its relationship with risk factors among neonates hospitalized in neonate intensive care unit [NICU]. It was a cross-sectional study on 234 NICU hospitalized neonates in Ghaem and Imam-Reza hospitals of Mashhad. Epidemiologic and pathologic information were obtained. Otoacoustic emissions were done in all of neonates. Patients referred to the second otoacoustic emissions [OAEs] and patients failed in the second test controlled by auditory brainstem response [ABR]. Hearing abnormality was found in 11 neonates [4.7%] including 2 girls and 9 boys. [1 neonate with mild, 2 with mild to moderate, 2 with moderate to severe, 1 with sever to profound hearing loss and 4 with auditory neuropathy]. Hearing abnormality has a significant greater incidence in group with apgar patients with icterus [in need with transfusion]. Incidence of hearing loss in NICU hospitalized neonates is greater in comparison with general population. It has a greater incidence in group with icterus [in need with transfusion] and apgar > 5, so, a comprehensive hearing screening program must be applied for early identification and intervention
