Prenatal management of twin gestation. Experience with a new protocol.

: We carried out a prospective cohort study to evaluate the usefulness of a specific protocol of prenatal management of twin pregnancy to decrease the incidence of prematurity in the population. The protocol particularly stressed the importance of early recognition of uterine contractile activity and early work leave (from 28 weeks' gestation). The outcome of 39 consecutive twin pregnancies that used the protocol over a five-year period was compared with the outcome of 76 twin pregnancies followed by private practitioners and delivered at our department. The two groups were comparable with respect to maternal age, parity, gestational age at diagnosis, socioeconomic level and educational level. The incidence of preterm delivery was significantly lower in the study group than in the control group. Even more significant was the difference in the incidence of severe prematurity (less than 34 weeks' gestation) between the two groups. The use of a protocol like ours, which does not include prolonged hospitalization, home bed rest or tocolytic treatment, is recommended.
