Sponsor's own description
Objective:To explore the study of Doppler ultrasound in first trimester pregnancies to measure the change of uterine artery blood flow in normal pregnancies and the prediction on abortion, which provides a certain reference for the change trend of uterine artery blood flow in normal first trimester pregnancies and the prediction of Doppler ultrasound measurement in abortion. Method:Pregnant women who underwent natural conception and single birth prenatal examination in the Obstetrics Department of the Second Affiliated Hospital of Wenzhou Medical University from October 1, 2023 to December 31, 2025 were selected as the study population. Eligible women were preliminarily screened according to the inclusion conditions of the study objects, and basic information of women in each group was compared: Maternal age, gestational time, birth time, gestational week, abortion history, maternal BMI, maternal MAP, smoking status, serum HCG, subchorionic hematoma, fetal bradycardia, left and right uterine aorta pulse index (PI), resistance index (RI) and systolic/diastolic ratio (S/D), etc. To investigate the effect of Doppler ultrasonography on the measurement of uterine artery blood flow in normal pregnancy and the prediction of abortion.
