Single Versus Repeat Betamethasone in Twin Pregnancies

Twin; Complicating Pregnancy Clinical Trial

Official title: Repeat Versus Single Course of Betamethasone in Twin Pregnancies

Status Not yet recruiting

Clinical Trial Summary

Thus far no robust data exist as to the effect of repeted course of antenatal corticosteroids in twin pregnancies. The investigators hypothesized that repeat course of betamethasone would further reduce neonatal morbidity in twins born before 34 weeks' gestation when compared with single dose.

Clinical Trial Description

Observational data suggest benefits in multiple gestations exposed to antenatal corticosteroids, although these studies have not consistently reported a statistical benefit or the benefits achieved in singletons. Nevertheless, based on the improved outcomes reported in singleton gestations, one course of antenatal corticosteroids is administered to all patients who are between 24 weeks and 34 weeks of gestation and at risk of delivery within 7 days, irrespective of the fetal number. Moreover, "a repeat course" of antenatal corticosteroids should also be considered in women who are less than 34 weeks of gestation who have an imminent risk of preterm delivery within the next 7 days, and whose prior course of antenatal corticosteroids was administered more than 14 days previously, again, irrespective of the fetal number.

The objective of the current study is to evaluate fetal outcomes in twin pregnancies following repeat betamethasone administration during pregnancy. ;
