Physical Features Of Newborns Exposed During Pregnancy To Anticonvulsant Medication And Developmental Monitoring

Background Antiepileptic drug (AED) use during pregnancy can affect the physical features, intelligence, and behavior in the exposed infants and children. Identifying these AED-related effects early makes intervention in childhood possible. To examine the accuracy of the identification of AED effects on the physical features of newborn infants, the written findings in routine physical examinations in medical records can be evaluated.Methods Documentation of AED exposure and the physical findings recorded was obtained from the hospital medical records of 207 infants at a large birthing hospital. Comparison was made of the findings in these infants by private pediatricians and two study pediatricians who were unaware of infant exposure status. The comparisons of the findings were analyzed using the Kappa statistic.Results The level of agreement in the assessment of the presence of facial features characteristic of midface hypoplasia by private pediatricians and the study pediatricians was poor (Kappa = 0.04; 95 CI-0.07 to 0.01); for microcephaly was fair (Kappa = 0.39; CI-0.14 to 0.93); and for growth restriction was fair (Kappa-0.22; CI-0.18 to 0.63).Conclusions Findings recorded by hospital pediatricians in medical records during routine medical care showed that most (74%) of the pediatricians were aware of the infant's exposure to AED during pregnancy. Pediatricians did not do well in identifying the physical signs of midface or digit hypoplasia or microcephaly or growth restriction. Better early identification of the physical effects from AED exposure would make it possible for infants to benefit from developmental monitoring.
