Insights
Hearing loss affects infants in neonatal intensive care units. Risk factors like prematurity and low birth weight increase the likelihood of hearing impairment in these vulnerable infants.
Area of Science:
- Neonatal care
- Audiology
- Pediatric neurology
Context:
- Neonatal intensive care units (NICUs) are critical for high-risk infants.
- Hearing impairment is a significant concern in this population.
- Early detection and risk factor analysis are crucial for intervention.
Purpose:
- To estimate hearing function in infants discharged from NICU.
- To identify risk factors associated with hearing loss in these infants.
- To analyze auditory thresholds using Auditory Brainstem Response (ABR).
Summary:
- Auditory Brainstem Response (ABR) testing was conducted on 287 infants (3-6 months post-discharge).
- Elevated auditory thresholds were detected in 48 infants initially, with 27 showing persistent issues.
- Key risk factors identified include gestational age < 33 weeks, birth weight < 1500g, respiratory/cardiovascular issues, and intracranial hemorrhages.
Impact:
- Highlights the prevalence of hearing deficits in NICU graduates.
- Identifies critical risk factors for targeted screening and prevention.
- Informs clinical practice for audiological follow-up in high-risk neonates.
Abstract:
The aim of the study was the estimation of hearing and the analysis of the risk factors for hearing loss in infants treated in neonatal intensive care units. The examinations were performed in 287 infants, who we examined in ENT Department between the ages of three and six months after discharge from neonatal intensive care unit. The infants were investigated with the use of ABR elicited with clicks and tone burst of 500 and 1000 Hz. Elevated auditory thresholds were found in 48 neonates in the first examination and in 27 in the second examination. Among the risk factors we observed the most frequently: gestational age < 33 Hbd, birth weight < 1500 g, respiratory and cardiovascular disorders and intracranial haemorrhages.
