摘　　要：目的:探讨彩色多普勒超声应用于宫内发育迟缓胎儿静脉血流频谱检测中的应用价值。方法:选取北京航天总医院2019年8月—2021年10月接收的64例宫内发育迟缓胎儿患者作为试验组;另选取同一时间段接收的60名健康孕妇作为对照组,两组对象均行彩色多普勒超声检查,比较并分析两组对象的检测结果。结果:试验组对象的脐动脉搏动指数(PI)、脐动脉阻力指数(RI)和脐动脉收缩期峰值与舒张期末期的流速比值(S/D)三项指标均高于对照组,组间差异有统计学意义(P<0.05);脑动脉的三项指标均显著低于对照组(P<0.05);试验组肾动脉RI显著高于对照组(P<0.05),PI、S/D与对照组比较差异无统计学意义(P>0.05)。脐静脉导管及脐静脉血流参数各指标比较,试验组下腔静脉反流分数、脐静脉导管血流量QDV、脐静脉导管分流率高于对照组,脐静脉血流量QUV低于对照组,组间差异均有统计学意义(P<0.05)。结论:在宫内发育迟缓胎儿静脉血流频谱的监测中彩色多普勒超声可起到理想的应用价值,值得在临床实践中借鉴并予以推广。Objective To investigate the application value of color Doppler ultrasound in the detection of venous blood flow spectrum in fetuses with intrauterine growth retardation.Methods A total of 64 patients with intrauterine developmental delay admitted to Beijing Aerospace General Hospital from August 2019 to October 2021 were selected as the experimental group.In addition,60 healthy pregnant women received in the same time were selected as the control group.Both groups underwent color Doppler ultrasound examination,and the detection results of the two groups were compared and analyzed.Results Object of trial umbilical artery pulsation index(PI),resistance index(RI) and umbilical artery systolic peak and late diastolic velocity ratio(S/D) three indicators were higher than those in the control group;The difference between groups was statistically significant(P<0.05).The three indicators of cerebral artery were significantly lower than those in the control group(P<0.05).Renal artery RI in experimental group was significantly higher than that in control group(P <0.05),while PI and S/D were not significantly different from those in control group(P> 0.05).Comparison of umbilical vein catheter and umbilical vein blood flow parameters showed that inferior vena cava reflux fraction,umbilical vein catheter blood flow QDV and umbilical vein catheter diversion rate in experimental group were higher than those in control group,while umbilical vein blood flow QUV was lower than that in control group,with statistical significance(P <0.05).Conclusion Color Doppler ultrasonograhy plays an ideal role in the monitoring of venous blood flow spectrum of fetus with intrauterine growth retardation,which is worthy of reference and promotion in clinical practice.
