Vaginal Progesterone in Twin With Short Cervix

Preterm Birth Clinical Trial

Official title: Evaluation of the Role of Vaginal Progesterone in Prevention of Preterm Labor in Twin Gestation With Short Cervix: Randomised Controlled Trial

Status Completed

Clinical Trial Summary

Aim of the work The aim of this study is to assess the efficacy of the use of vaginal progesterone as a method of prevention of preterm labour in twin gestations with short cervix .

Study Design:

The study is designed as randomized ,placebo-controlled, clinical trial . All women with dichorionic diamniotic twin pregnancy will be followed up in the antenatal care at the out patient clinic. Randomization of cases will be done by computer method . 156 women with dichorionic diamniotic twin pregnancy and cervical length 10mm to 25mm detected on transvaginal sonogram between 20w to 24w gestational age were enrolled in the study and were distributed in two groups:group P (cases ) and group N (controls) . The randomization allocation was 1 : 1 (vaginal progesterone capsule : placebo).
