Neonatal acoustic reflex -Relationship to birth weight, postnatal age
Arthroplasty, Replacement, Hip
Range of Motion, Articular
Ipsilateral acoustic reflex was tested in 75 normal neonates using a 220 H2 probe tone. The age of the neonates ranged from 24 hours to 192 hours and the birth weight from 2.5 kg to 3.8 kg. It was observed that the reflex is detectable in all neonates more than 4 days old and has a significant relationship with the birth weight. We feel that this test should be utilized routinely as one of the investigative procedures in all neonatal auditory screening programmes. © 1993 Association of Otolaryngologists of India.
