  • Title: The impact of antenatal cocaine use on maternal characteristics and neonatal outcomes.
    Author: Ogunyemi D, Hernández-Loera GE.
    Journal: J Matern Fetal Neonatal Med; 2004 Apr; 15(4):253-9. PubMed ID: 15280134.
    Abstract:
    OBJECTIVE: To determine the risk factors and evaluate maternal and neonatal outcomes associated with antenatal cocaine use. METHODS: This was a retrospective case-control study of 200 cocaine-exposed maternal-neonatal pairs and 200 controls from 1991 to 2000. RESULTS: Cocaine-using mothers tended to be older, African American, multiparous and incarcerated and they utilized less prenatal care. However, 79% of Hispanics abusing cocaine were primarily English speaking. Cocaine use correlated with syphilis (36 vs. 1%, p = 0.000) and premature rupture of membranes (23 vs. 0%, p = 0.000), fetal demise (5 vs. 0%, p = 0.004), preterm delivery (40 vs. 6%, p = 0.000). Cocaine-exposed infants delivered earlier (36 vs. 39 weeks, p = 0.000), had lower birth weights (2660 vs. 3305 g, p = 0.000), more respiratory distress syndrome (14 vs. 4%, p = 0.001), congenital syphilis (12 vs. 1%, p = 0.000) and longer hospital stays (10 vs. 3 days, p = 0.000); 75% were placed in foster care or adoption and 37.5% had neonatal withdrawal syndrome. There was a stronger positive correlation between neonatal withdrawal and maternal urine toxicology (rho = 0.443, p = 0.000) than with neonatal urine screen (rho = 0.278, p = 0.003). CONCLUSION: Cocaine use in pregnancy is associated with acculturation, lack of prenatal care, and significant social and obstetric complications resulting in increased neonatal morbidity secondary to prematurity, congenital infection and withdrawal syndrome.
