Clinical Trial Summary

The aim of this study is to evaluate the effectiveness of ultrasonographic parameters (cervical length, placental thickness and distance placental edge from internal os of the cervix) in predicting the risk of antepartum hemorrhage and emergency cesarean delivery in asymptomatic women with placenta previa.

Description:

The incidence of placenta previa is 3-5 per 1000 pregnancies worldwide and is still rising because of increased maternal age, parity, cesarean section rates, assisted reproductive technology, maternal smoking with the widespread use of transvaginal ultrasound. antepartum hemorrhage is an important cause of maternal and neonatal morbidity and mortality in pregnant women with placenta previa. However, the epidemiological characteristics are not completely understood. this study aims at evaluating the sonographic findings in asymptomatic women with placenta previa as cervical length, placenta thickness and distance from cervix to placental edge to recommend management for in-patients versus out-patient antenatal care and early planned hospital admission and delivery for women at high risk of antepartum hemorrhage and preterm cesarean section and hysterectomy for life threatening antepartum hemorrhage.

Eligibility

Inclusion Criteria:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	maternal bleeding rate	number of attacks of antepartum hemorrhage	till delivery
Secondary	Blood transfusion	number of PRBCs	till delivery 36 to 37 weeks
Secondary	Emergency Cesarean section	severe antepartum hemorrhage requiring delivery	till delivery 36 to 37 weeks
Secondary	Premature delivery	before the planned delivery date (before 37 weeks' gestation)	37 week's gestation
Secondary	Need for cesarean hysterectomy	cesarean hysterectomy due to bleeding or placenta accreta spectrum	during cesarean section
Secondary	Postpartum hemorrhage	severity of attacks and required further management or blood transfusion	Within 2 hours of delivery
