摘要
目的探究彩色多普勒超声对脐带绕颈胎儿血流及宫内窘迫的诊断效能。方法回顾性分析2021年1月至2022年8月于赣州市人民医院接受产检的192例孕妇及其胎儿的临床资料,根据彩色多普勒超声检查显示是否存在脐带缠绕分为A组(无脐带缠绕,n=82)和B组(有脐带缠绕,n=110)。并根据B组胎儿是否发生宫内窘迫分为B1组(发生宫内窘迫,n=38)与B2组(未发生宫内窘迫,n=72)。比较各组脐动脉、大脑中动脉脐动脉收缩末期与舒张末期血流速度比值(S/D)、阻力指数(RI)水平,分析彩色多普勒超声经脐动脉、大脑中动脉对胎儿宫内窘迫的诊断效能。结果B组脐动脉S/D、RI水平均高于A组,大脑中动脉S/D、RI水平均低于A组,差异有统计学意义(P<0.05)。B1组脐动脉S/D、RI水平均高于B2组,大脑中动脉S/D、RI水平均低于B2组,差异有统计学意义(P<0.05)。联合诊断对胎儿宫内窘迫诊断的准确度高于脐动脉、大脑中动脉单独诊断,灵敏度、特异度均高于脐动脉单独诊断,差异有统计学意义(P<0.05)。结论彩色多普勒超声对脐带缠绕患儿发生宫内窘迫的诊断效能良好,脐动脉、大脑中动脉联合诊断可提升诊断效能。
Objective To explore the diagnostic efficacy of color Doppler ultrasound in fetal blood flow and intrauterine distress with umbilical cord around the neck.Methods The clinical data of 192 pregnant women and their fetuses who received antenatal examination in Ganzhou People's Hospital from January 2021 to August 2022 were retrospectively analyzed,they were divided into the group A(without umbilical cord entangling,n=82)and the group B(with umbilical cord entangling,n=110)according to the presence or absence of umbilical cord entangling by color Doppler ultrasound.They were divided into the group B1(intrauterine distress occurred,n=38)and the group B2(no intrauterine distress occurred,n=72)according to whether fetuses in the group B developed intrauterine distress.The levels of ratio of end-systolic to end-diastolic blood flow velocity(S/D),resistance index(RI)of umbilical artery and middle cerebral artery in each group were compared,and the diagnostic efficacy of color Doppler ultrasound through umbilical artery and middle cerebral artery in fetal distress was analyzed.Results The levels of umbilical artery S/D and RI in the group B were higher than those in the group A,and the levels of S/D and RI in middle cerebral artery were lower than those in the group A,and the differences were statistically significant(P<0.05).The levels of umbilical artery S/D and RI in the group B1 were higher than those in the group B2,and the levels of S/D and RI in middle cerebral artery were lower than those in the group B2,and the differences were statistically significant(P<0.05).The accuracy of combined diagnosis in the diagnosis of fetal distress was higher than that of single diagnosis of umbilical artery and middle cerebral artery,and the sensitivity and specificity were higher than those of single diagnosis of umbilical artery,and the differences were statistically significant(P<0.05).Conclusion Color Doppler ultrasound is effective in the diagnosis of intrauterine distress in children with umbilical cord entanglement,and the
