Abstract: Objective To study the estimated value on normal reference ranges of inferior vena cava (IVC) Doppler indices from gestation 16 to 40 weeks of fetus with color ultrasound.Methods Seven hundred and forty-four single birth gravida with gestation 16 to 40 weeks were grouped according to the gestational weeks with 27-35 cases each.The IVC Doppler indices were measured by color ultrasound,including preload index,peak velocity index and pulsatile index.Results All IVC Doppler indices rapidly declined from gestation 16 to 24 weeks,and they were relatively constant or slightly decreased throughout the end of pregnancy.Conclusions To set up the normal reference ranges of IVC Doppler indices for gestation from 16 to 40 weeks means a lot for every pregnant.This normative data may be a useful noninvasive tool for evaluation of fetal cardiac function.
