title: Induction of labour and scheduled cesarean deliveries in twin pregnancies at the Port-Royal Maternity Hospital in Paris France.
abstract: The study is a critical analysis of the decisions to induce labour or schedule cesareans in the practice of a third level referral centre, with as outcome criterion the reduction of fetal death. 783 women pregnant with twins were included from 1.1.1993 to 31.12.1998, in three groups: originally booked, referred for care during pregnancy, or transferred from another institution. The results show that an important proportion of preterm deliveries result from a medical decision to induce labour or from a scheduled cesarean in the originally booked group with even higher proportions in groups of referred and transferred women. These results are discussed in relation to fetal death rates and causes. Deaths related to fetal growth restriction were not observed in women originally booked for care. The hospital bias has been discussed. The conclusion is that decisions to minimize fetal deaths in twin pregnancies increased preterm deliveries by medical decision.
