[Non-respiratory cyanosis in the newborn].

Four term babies, three boys and one girl, became cyanotic shortly after birth. In two cases the cause was maternal use of drugs: methemoglobinaemia due to use of a chromate and depression of the nervous system due to clomipramine. They recovered. A third child suffered cerebral infarction and was left with decreased left-arm function. The fourth child had a hypoplastic left heart and died. Central cyanosis in a newborn should be cause for concern. A thorough case history should be taken and extensive physical examination carried out. In case of doubt additional diagnostic tests should be performed.
