Summary
Premature twins showed prolonged brainstem auditory evoked response (BAER) central conduction time compared to non-twins. This finding suggests intra-uterine growth retardation may impact auditory pathway development in twins.
Area of Science:
- Neuroscience
- Developmental Pediatrics
Background:
- Premature birth poses risks to neurodevelopment.
- Twin pregnancies often experience intra-uterine growth retardation.
Purpose of the Study:
- To investigate auditory pathway development in premature twins versus non-twins.
- To assess if intra-uterine growth retardation affects brainstem auditory evoked response (BAER) in premature infants.
Main Methods:
- Brainstem Auditory Evoked Response (BAER) recordings were obtained.
- 20 premature twins and 20 premature non-twins were studied.
- Groups were matched for conceptional age, gestational age, birthweight, and other factors.
Main Results:
- A significant prolongation of central conduction time (I-V interval) was observed in premature twins.
- This prolongation indicates delayed auditory pathway maturation.
Conclusions:
- Premature twins exhibit delayed central auditory conduction.
- Intra-uterine growth retardation in twins may be a contributing factor to altered neurodevelopmental outcomes.
