Summary

Infants with persistent fetal circulation have a high risk of hearing loss. Early and serial hearing tests are crucial for detecting sensorineural hearing impairment in these vulnerable infants.

Area of Science:

  • Neonatology
  • Audiology
  • Pediatric Medicine

Background:

  • Persistent fetal circulation (PFC) is a critical condition in neonates.
  • Hearing impairment is a potential complication in infants with PFC.
  • Early identification of hearing loss is vital for infant development.

Purpose of the Study:

  • To evaluate the incidence of hearing loss in infants diagnosed with persistent fetal circulation.
  • To identify perinatal factors associated with hearing impairment in this population.
  • To recommend audiological follow-up strategies for affected infants.

Main Methods:

  • Retrospective and prospective evaluation of infants with PFC.
  • Formal audiologic testing including serial evaluations.
  • Comparison of perinatal factors between infants with and without hearing loss.

Main Results:

  • Over 40 infants evaluated, 52.5% (21/40) had hearing impairment; 14 required hearing aids.
  • Parental concern was noted in 82% of hearing-impaired infants requiring hearing aids.
  • Progressive hearing loss was diagnosed 6-8 months post-NICU discharge in some prospectively followed infants.
  • Factors associated with hearing loss included alkalosis, ventilation duration, and furosemide use.

Conclusions:

  • Infants with persistent fetal circulation exhibit a very high incidence of sensorineural hearing loss.
  • Serial formal audiologic evaluations are recommended for early detection.
  • Identifying associated perinatal factors can inform management and prevention strategies.
