摘　　要：目的:探讨孕晚期超声大脑中动脉、脐动脉、子宫动脉超声参数与胎儿宫内窘迫的发生。方法:收集本院2020年1-12月收治的孕妇临床资料,按照是否存在宫内窘迫分为观察组和对照组各60例。比较两组孕妇子宫动脉(UtA)及胎儿大脑中动脉(MCA)、脐动脉(UmA)超声血流动力学参数及新生儿结局,胎儿宫内窘迫发生情况。结果:从超声血流动力学参数阻力指数(RI)、搏动指数(PI)、脐动脉收缩期最大血流速度比舒张期血流速度(S/D)进行组间比较,孕妇UtA观察组高于对照组(P<0.05);胎儿MCA、UmA的PI、S/D观察组与对照组存在差异(P<0.05),RI两组无差异(P>0.05)。新生儿Apgar评分8~10分观察组(66.7%)低于对照组(90.0%),新生儿体重(2675.5±27.6g)低于对照组(3117.5±31.2g);观察组剖宫产率(70.0%)高于对照组(11.7%),早产率(40.0%)高于对照组(10.0%),胎儿窘迫、新生儿生长受限和新生儿窒息发生率均高于对照组(均P<0.05)。结论:胎儿宫内窘迫孕妇孕晚期胎儿MCA、UmA和孕妇UtA血流动力学发生异常,提示临床予以关注,加强监测为临床干预提供指导。Objective:To study the correlation between the ultrasound parameters values of the fetal middle cerebral ar-tery(MCA)and the umbilical artery(UmA)of fetuses and the pregnant women uterine artery(UtA)and the risk as-sessment of the fetal intrauterine distress.Methods:The clinical data of 120 pregnant women from January 2020 to De-cember 2020 were collected.These women were divided into observation group and control group(60 cases in each group)according to the occurrence of the fetal intrauterine distress.The values of UtA and fetal MCA and UmA,the outcomes of newborns,and the situation of fetal intrauterine distress were compared between the two groups.Results:The values of ultrasonic hemodynamic parameters,such as resistance index(RI)and pulsation index(PI),the value of maximum systolic blood velocity ratio to diastolic blood velocity(S/D)of UtAof the women in the observation group were significantly higher than those of the women in the control group(P<0.05).The values of PI and S/D of fetal MCA and UmA in the observation group were significantly different from those of the fetuses in the observation group(P<0.05),but the RI values of MCA and UmA of the fetuses had no significant differences between the two groups(P>0.05).The rate of neonatal Apgar score of 8-10 points(66.7%)and the neonatal body weight(2675.5±27.6g)in.the observation group were significantly lower than those(90.0%and 3117.5±31.2g)in the control group,but the rates of cesarean section(70.0%)and the premature delivery(40.0%)of the women in the observation group were significantly higher than those(11.7%and 10.0%)of the women in the control group.The incidences of fetal distress,neonatal growth restriction,and neonatal asphyxia of the women in the observation group were significantly higher than those of the women in the control group(all P<0.05).Conclusion:The hemodynamics of fetal MCA and UmA,and UtA of the pregnant women with fetal distress during the third trimester of pregnancy are abnormal,which should be paid attention in clinic and the
