Summary. Forty‐two primigravidae with unripe cervices (modified Bishop score ≤5) were pretreated with 8 mg of oral salbutamol 30 min before vaginal administration of 5 mg of PGE 2 . The proportion of patients in established labour after treatment (19%) was markedly less than results reported previously and cervical improvement occurred in 86% of the non‐labouring patients. The improved outcome of labour associated with the prior administration of PGE 2 when the cervix is unripe, including reduced induction‐to‐delivery intervals and higher rates of vaginal delivery was maintained. Apart from some minor side‐effects, there were no adverse effects noted as a direct consequence of the tocolytic; blood loss was not increased, although one patient suffered an intrapartum abruption. This approach allows a greater control of induced uterine activity and timing of delivery which may be of particular importance in women with suspected placental insufficiency.
