Use of nerve conduction velocity to determine gestational age in infants at risk and in very-low-birth-weight infants.
Nerve conduction velocity was used to measure gestational age in at risk and very-low-birth-weight neonates. The method gave highly significant correlations with gestational estimates by the Dubowitz score and with confirmed maternal dates; 86% of the estimates agreed within two weeks with confirmed maternal dates. The method is valid in babies 30 weeks old or younger and is reproducible after the first postnatal week. There was no difference in babies small for gestational age. The technique was estimated to predict gestation with a standard deviation of +/- 1.14 weeks.
