ABSTRACT
Birth asphyxia is an insult to the fetus or newborn due to lack of oxygen and/or inadequate perfusion to the various organ, especially to the brain. The most important and serious complication of the asphyxia is the hypoxic ischemic encephalopathy. It has been postulated that the auditory brainstem responses(ABR) might be helpful to evaluate the severity of the brainstem lesions by the birth asphyxia.
In this study ABR were performed in the 67 full term neonates who had birth asphyxia with Apgar scores 5 or less and 26 normal control neonates. And the latencies,inter-peak latencies, and amplitudes were compared.
The results were as follows:
There were no statistically significant difference in ABR latencies at 90 dB HL between the neonates with the birth asphyxia and the control group(p>0.05).
The latencies of wave V at 30, 45, 60 and 90 dB HL were tended to delay in the asphyxia group compare to the control group although there was no statistical significance (p>0.05).
There were statistically significant dimunution of amplitudes of wave V at 30, 45, 60, 90 dB HL and the amplitude of wave I at 90 dB HL in the asphyxia group(p>0.05).
