Abstract：Objective To investigate the hemodynamic difference of uterine artery between parturient and primipara during full-term pregnancy by color Doppler ultrasonography. Methods The clinical and ultrasound data of 185 pregnant women with late pregnancy in the Affiliated Jiangyin Hospital of Southeast University Medical College and Jiangyin Hospital Affiliated to Nanjing University of Chinese Medicine from January 2016 to April 2020 were retrospectively analyzed. The 185 pregnant women were aged between 23 and 41 [29 (28,32)] years and were 37.1–41.9(39.6±1.1) weeks in gestational age before delivery. A total of 81 cases of multiparous women were classified as the multiparous women group, and 104 cases of primiparous women were classified as the primiparous women group. The baseline datas of age, gestational age, height, weight, body mass index (BMI) and incidence of hypertensive disorders, diabetes, and anemia during pregnancy were observed and compared between the two groups. The occurrence rate of uterine artery early diastolic notch and hemodynamic parameters such as pulsatile index (PI), resistance index (RI), and peak systolic velocity/end diastolic velocity (S/D) were compared between the two groups. Results (1) No significant differences were observed in age, gestational age, height, weight, BMI and the incidence of hypertensive disorders, diabetes, and anemia during pregnancy between the multiparous women group and the primiparous women group (all P values >0.05). (2) The occurrence rate of early diastolic incision of uterine artery was 6.17% (5/81) and 6.73% (7/104) in the parturient and primipara groups, respectively, with no statistical significance (χ2=0.02, P=0.879). The RI values were 0.51 (0.45, 0.55) and 0.50 (0.46, 0.52), the PI values were 0.82 (0.69, 0.92) and 0.79 (0.68, 0.88), and the S/D values were 2.01 (1.84, 2.25) and 2.00 (1.85, 2.10) in the multiparous women group and the primiparous women group, respectively. No statistical significances were observed in both groups (Z=0.98, 0.73, 1.05, all P values >0.05). Conclusion sNo differences were observed in the hemodynamic parameters of uterine artery by ultrasonography between the multiparous women and primiparous women during full-term pregnancy.
