Anaesthesia was induced with equipotent doses of either thiopentone or methohexitone in 127 women undergoing Caesarean section. They divided into three groups: those having normal placental function, those with an undefinable degree of placental insufficiency, and emergencies. There was no clinical or biochemical difference in the neonates following induction of anaesthesia with either thiopentone or methohexitone. The clinical condition of neonates born of mothers with normal placental function was superior to the other two groups.
