Hearing screening failure rate in newborn infants with hypoxic ischemic encephalopathy

Area of Science:

• Neonatal care
• Auditory health
• Neurology

Background:

• Hypoxic ischemic encephalopathy (HIE) is a serious birth complication.
• Hearing impairment is a potential consequence of HIE.
• Early identification of hearing issues is vital for infant development.

Purpose of the Study:

• To determine the incidence of hearing screening failure in newborns across all stages of HIE.
• To analyze hearing screening failure rates based on HIE severity and therapeutic hypothermia.
• To highlight the need for careful management and follow-up for hearing loss in HIE infants.

Main Methods:

• Retrospective cohort study in a tertiary neonatal intensive care unit.
• Analysis of medical records and hearing screening results for 177 infants with HIE over two years.
• Comparison of hearing screening failure rates across HIE stages and treatment groups.

Main Results:

• Overall hearing screening failure rate was 19% (35 out of 177 infants).
• Failure rates were similar across HIE stages (19% for Stage 1, 19% for Stage 2, 23% for Stage 3).
• Therapeutic hypothermia did not significantly impact hearing screening failure rates (20% vs 19%).

Conclusions:

• Hearing screening failure is common in HIE infants, including those with Stage 1 HIE.
• Increased risk of hearing loss necessitates careful management and strict long-term follow-up for all HIE stages.
• Early audiological monitoring should be a standard part of care for infants with HIE.
