Objective: To study the hearing screening of newborn
at Newborn Intensive Care Unit.
Methods: This was a retrospective study, all data
were retrieved from medical records of 729 cases at
Newborn Intensive Care Unit, Roi Et Hospital during
October 1, 2013 to July 31, 2019. The hearing loss
screenings were used Distortion-product otoacoustic
emissions (DPOAEs) by audiologist took time for 1-2
minutes per ear. The sound used for examination was
loudness approximately level 60-70 decibels which
was not harmful to ears and hearing of infant. The
echo measurement was performed by audiologist by
insert probe to outer ear canal of infant. Then released
sound to stimulate and record the response of the
inner ear. The machine will automatically process and
reported the results that Pass or Refer. The statistics
used for data analysis were descriptive statistics, Chisquare
test and Fisher’s Exact test. The statistical
significance was set at p <0.05.
Results: Of 729 infants most of them were male
59.67%, preterm birth 42.25%, birth weight < 1,500
gram 15.09%, hearing screening Pass both ear 90.53%,
Refer both ear 4.66%. Right ear Refer 1.23%, Left ear
Refer 0.27%. The factors associated with hearing loss
of infants in Newborn Intensive Care Unit were Craniofacial
anomalies (p=0.001), Ototoxic medication
(p=0.019), Low apgar score (p=0.036), On mechanical
ventilator (≥7 days) (p=0.011) and Stigmata associated syndrome to include Stigmata associated syndrome
to include sensorineural hearing loss 1 conductive
hearing loss (p=0.026). Rate of hearing screening was
97.07%, referral rate was 4.66% and follow up rate
was 47.05%. Of 6 infants has diagnosed for hearing
loss (0.83 %), received hearing aid 5 cases, and loss
follow up 1 case.
Conclusion: This study revealed that the hearing loss
screening of newborns in high risk group at the Neonatal
Intensive Care Unit that very important. It was
found out that the risk factors of hearing loss of
newborn had several factors. The newborns at risks
should be monitored and continuously to treated, if
abnormalities were found the treatment and recovery
should promptly performed.
