Objective:
To examine brainstem auditory evoked potential (BAEP) in preterm infants after perinatal hypoxia within 3 days and 1 month after birth.
Methods:
BAEP was studied in 42 preterm infants after perinatal hypoxia within 3 days and 1 month after birth, and was compared with those in preterm without any major perinatal problems.
Results:
The latencies of wave V and the interpeak intervals of III-V and I-V in BAEP of hypoxia preterm infants differed significantly from those in the control with 3 days after birth. One month later, the latencies of wave and the interpeak intervals in BAEP of hypoxia infants were improved, and there were no significant differences between two groups.
Conclusion:
Central auditory function in preterm infants will be damaged by perinatal hypoxia, which must be taken into account even the damage could be improved in 1 month after birth.
