Abstract
As phencyclidine hydrochloride (PCP) has become one of the more frequently abused drugs in the United States, there has been increasing interest in its effect on the fetus and neonate of the pregnant abuser. Two groups of women enrolled in a comprehensive perinatal addiction program were studied: 7 women abused PCP prior to and during pregnancy, and these women were compared to a group of 27 drug-free women. No differences between the two groups were seen in maternal age, gravidity, gestational age or Apgar scores. At birth, there was no difference in birth weight, length, or head circumference between the two groups of neonates. The most characteristic features of the PCP- exposed infants were the sudden outbursts of agitation and rapid changes in level of consciousness, similar to responses described in adults intoxicated with PCP. Scores on the Brazelton Neonatal Behavioral Assessment Scale revealed a significant increase in lability of states and poor consolability in PCP-exposed infants. 3-month scores on the Bayley Scales of Infant Development revealed no significant difference between the two groups of infants.
