脐血流S／D值监测与评价

目的应用胎儿脐血流检测仪测定脐血流S／D比值，结合妊娠结局分析其监测胎儿宫内安危的临床价值。方法检测206例孕妇妊娠28～42周的胎儿脐动脉血流频谱，按监测所得S／D比值分为异常组（S／D≥3）96例与正常组（S／D〈3）110例，分析其妊娠母婴结局及分娩方式。结果两组病例的脐带绕颈、羊水过少、妊娠期高血压疾病、胎儿窘迫、新生儿窒息和胎儿生长受限等发生率及分娩方式有统计学意义。结论脐血流S／D值是测定胎儿宫内安危较为灵敏的指标，可指导临床及早采取干预和处理措施，提高围产保健质量。

Umbilical cord blood flow S/D value monitoring and evaluation

Objective To analyze the clinical value of umbilical blood flow monitoring in forecasting the fetal safety in uterus.Methods Umbilical Blood Flow Detector was used to detect the resistance index(RI) and the ratio of S/D of 206 cases 28~42 weeks pregnant women,and then dividing into the abnormal group(S/D≥3) with 96 patients and normal group(S/D<3) with 110 cases;analyzing the pregnant outcome and the mode of delivery in both groups.Results The incidence rates of umbilical cord round the neck,hypamnion,gestational hypertension,fetal distress,neonatal asphyxia,and fetal growth restriction had significant statistically difference between the two groups.Conclusion Umbilical blood flow detection is a safe,reliable,and more sensitive indicators of predicting intrauterine fetal condition,which can guide the clinical early intervention and treatment measures,and improve the perinatal care quality.
