NCT04631627

Brief Summary

This study intends to adopt the method of multi-center prospective randomized controlled study. The aim of this study is to obtain localized excision values through a preeclampsia screening model established in early pregnancy, and to evaluate the efficacy of low-dose aspirin intervention for preeclampsia prevention in pregnant women at high risk of screening.

Outcome Measures

Primary Outcomes (6)

  • the rate of preeclampsia

    Hypertensive onset after 20 weeks of gestation is accompanied by proteinuria,or with thrombocytopenia, impaired liver function, renal insufficiency,pulmonary edema,headache without other explanation and so on.

    through study completion, an average of 1 year

  • the rate of hypertensive disorder during pregnancy

    gestational hypertension, preeclampsia, chronic hypertension with preeclampsia, eclampsia, HELLP syndrome

    through study completion, an average of 1 year

  • the rate of placenta abruption

    After 20 weeks of pregnancy, the placenta in its normal position is completely or partially removed from the uterine wall before delivery of the fetus

    through study completion, an average of 1 year

  • the rate of fetal growth restriction

    The birth weight of the fetus is below two standard deviations of the average weight for the same gestational age or below the 10th percentile of normal weight for the same age

    through study completion, an average of 1 year

  • the rate of postpartum hemorrhage

    Within 24 hours after the delivery of the fetus, the bleeding volume of vaginal delivery ≥500ml, cesarean delivery ≥1000ml

    within 24 hours after the delivery

  • the time and type of delivery

    gestational week, vaginal delivery and cesarean section

    within 24 hours after the delivery

Secondary Outcomes (3)

  • birth weight of newborn

    delivery time

  • Apgar score for newborns

    delivery time

  • the rate of Neonatal NICU occupancy rate

    through study completion, an average of 1 year

Study Arms (2)

aspirin group

ACTIVE COMPARATOR

aspirin,tablet,100/150mg per day,(BMI\<30 100mg/d,BMI≥30 150mg/d),from pregnancy weeks\<16 to 35 weeks or the day of delivery.

Drug: Aspirin

control group

SHAM COMPARATOR

with no intervention

Drug: Aspirin

Interventions

With the result of risk assessment for high risk and the risk of pregnant women, with each research center stratified random aspirin drug intervention, for each center screening high-risk and accord with the standard drug intervention study phase into eliminate pregnant women by using stochastic indicator 1:1 randomly into low-dose aspirin to prevent group and observation group, for each center in screening for risk and comply with the drug intervention study phase into the exclusion standard 1:1 by random indicator method pregnant women randomly into low-dose aspirin to prevent group and observation group.
