经产妇与初产妇足月妊娠时超声检测子宫动脉血流动力学参数的比较

目的 探讨彩色多普勒超声检测经产妇与初产妇足月妊娠时子宫动脉血流动力学参数的差异。方法 回顾性分析2016年1月—2020年4月东南大学医学院附属江阴医院及南京中医药大学江阴附属医院185例晚期妊娠孕妇临床及超声资料。185例孕妇年龄23~4129（28,32）]岁,孕周37.1~41.9（39.6±1.1）周。经产妇81例为经产妇组,初产妇104例为初产妇组,观察比较2组孕妇年龄、孕周、身高、体质量、体质量指数（BMI）以及妊娠期高血压疾病、糖尿病、贫血的发生率有无差异;比较2组孕妇子宫动脉舒张早期切迹的发生率及子宫动脉血流动力学参数搏动指数（PI）、阻力指数（RI）及收缩期峰值最高流速/舒张末期流速（S/D）值的差异。结果 （1）经产妇组与初产妇组年龄、孕周、身高、体质量、BMI以及妊娠期合并高血压疾病、糖尿病、贫血的发生率差异均无统计学意义（P值均>0.05）。（2）经产妇组与初产妇组的子宫动脉舒张早期切迹发生率分别为6.17%（5/81）、6.73%（7/104）,差异无统计学意义（χ²=0.02,P=0.879）;子宫动脉血流动力学参数RI分别为0.51（0.45,0.55）、0.50（0.46,0.52）,PI分别为0.82（0.69,0.92）、0.79（0.68,0.88）,S/D值分别为2.01（1.84,2.25）、2.00（1.85,2.10）,2组间比较差异均无统计学意义（Z=0.98、0.73、1.05,P值均>0.05）。结论 经产妇与初产妇足月妊娠时,超声检测子宫动脉的血流动力学参数无差异。

Comparision of uterine arterial hemodynamic parameters between parturient and primipara during full-term pregnancy by color Doppler ultrasonography

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.
