The outcome of pregnancies complicated by narcotic drug addiction.

Abstract

The incidence of known narcotic drug addiction at 2 Maternity Hospitals in Melbourne was 0.06% (45 of 80,950 confinements). The obstetric results of these 45 pregnancies were unexpectedly favourable, the main complications being fetal growth retardation (27%) and premature birth before 37 weeks (27%). There were no fetal malformations and only 1 perinatal death. Follow-up information is necessary to ascertain if the main hazard to these infants lies in the environment to which they return.
