[Heroin abuse and methadone substitution in pregnancy].

The pre- and postnatal data of 20 pregnant heroin addicts and their neonates are described. 16 women were treated with methadone to prevent withdrawal symptoms. A relatively stabile prenatal condition with a decrease of complications was achieved. On the other hand, the neonates suffered from severe withdrawal symptoms including seizures in spite of intensive paediatric care and prophylactic treatment with barbiturates. After a mean follow-up of one to two years a relatively good neurological development of the children was observed.
