Abstract
Back ground: Permanent hearing loss is a common neonatal health problem,
which can lead to deleterious effects on language and speech development and
academic outcome. Its prevalence especially the sensory neural type is much
higher in newborns that needed neonatal intensive care unit admission.
Methods: This cross-sectional study included 314 neonates admitted at neonatal
intensive care unit of Cairo university hospital between 1st of August 2019 and
31st of July 2021 with any risk factor of hearing impairment, as defined by the
joint committee on infant hearing. All the included neonates subjected to
detailed history taking and clinical evaluation. They were all evaluated by
transient evoked otoacoustic emission (TEOAE). Automated auditory brainstem
response (AABR) was done at three months of age for those neonates who failed
the TEOAE screening.
Results: Out of the 314 neonates, 4.5 % of cases were diagnosed with
permanent hearing loss. No statistical significance was detected between hearing
loss and gender (P value 0.610), prematurity (P value 0.529), birth weight (P
value 0.076). The most common risk factor detected was receiving ototoxic
drugs, with aminoglycosides being the most frequent ones. There was a
significant P value between ototoxic medications and hearing loss (P value
0.018). The highest percentage of cases with hearing loss was detected among
neonates who received both aminoglycosides and vancomycin.
Conclusion: The prevalence of permanent hearing loss among admitted
neonates at risk is high so screening is essential for early detection of cases and
hence early management. Use of ototoxic medications especially
aminoglycosides and vancomycin is a major risk factor for hearing loss.
Duration of ototoxic drug therapy as well as that of oxygen therapy is of
significant association with hearing loss.
