【摘要】目的 探讨彩色多普勒超声检测胎儿脐动脉(UA)、大脑中动脉(MCA)及静脉导管(DV)的血流动力学参数对预测胎儿窘迫的临床价值.方法 回顾性分析2015年5月至2016年9月于辽宁中医药大学附属医院产科病房足月分娩的孕妇120例,根据胎心率、羊水粪染及1min Apgar评分分成两组,正常孕妇75例,胎儿窘迫孕妇45例.应用彩色多普勒超声于妊娠35 ～41周检测两组胎儿的UA、MCA、DV的搏动指数(PI)、阻力指数(RI)、收缩期与舒张期流速比(S/D)及计算静脉导管分流率,并记录血流动力学参数.结果 脐动脉、大脑中动脉及静脉导管血流动力学参数变化诊断胎儿窘迫的灵敏度、特异度分别为84.44％、82.22％(UA),88.89％、77.78％(MCA),84.44％、86.67％(DV),三者联合检测的敏感度、特异度分别为95.56％、93.33％,差异具有统计学意义(P＜0.05).结论 通过检测孕晚期胎儿主要血管的血流动力学参数,有助于早期预测胎儿窘迫,可了解胎儿宫内血供情况及妊娠的可能结局,可以为提高胎儿的围产期质量提供量化而可靠的检查手段.%Objective Study on detection of fetal umbilical artery with color Doppler ultrasound (UA),middle cerebral artery (MCA)and venous catheter (DV)hemodynamic parameters,the results of clinical significance in predicting fetal distress.Methods A retrospective analysis from May 2015 to September 2016 in the Affiliated Hospital of
Liaoning University of Traditional Chinese Medicine obstetric wards of full-term pregnant women in 120 cases,according to the fetal heart rate,meconium

score(Apgar)were divided into two groups,75 cases of normal pregnant women,45 pregnant women with fetal distress,and the application of color Doppler ultrasound in 35 to 41 weeks of pregnancy in two groups were detected in fetal UA,MCA,DV pulsatility index (PI),resistance index (RI),systolic and diastolic flow velocity (S/D)and venous shunt rate calculation,and record the blood flow Mechanical parameters.Results Changes in the hemodynamic parameters of the umbilical artery,the middle cerebral artery and the venous catheter in sensitivity and specificity for diagnosis of fetal distress is 84.44％、82.22％ (UA),88.89％、77.78％ (MCA),84.44％、86.67％ (DV),the sensitivity of the three combined tests was 95.56％ and 93.33％,respectively,and the difference was statistically significant (P＜0.05).Conelusion The hemodynamic parameters of major vascular detection of late pregnancy fetal,help in early prediction of fetal distress,fetal outcome may understand the blood supply and pregnancy,the fetus can improve the quality of perinatal period to provide quantitative and reliable means of checking. 【总页数】4页(110-113)
