Vaginal Progesterone to Prevent Preterm Delivery in Women With Preterm Labor (4P)

June 5, 2012 updated by: begoña Martinez de Tejada, Begona Martinez de Tejada

Prevention of Preterm Delivery With Vaginal Progesterone in Women With Preterm Labor

The administration of vaginal progesterone, in addition to standard tocolysis, will decrease the risk of delivering prematurely and of recurrent preterm labor. We also hypothesize that the reduction in preterm delivery will be associated with a decrease in infant mortality and morbidity.

Detailed Description

The principal aim is to demonstrate that progesterone reduces preterm birth before 37 weeks of gestation.
