监测胎儿脐血流对预测胎儿宫内缺氧及胎儿预后的观察

目的通过监测胎儿脐动脉血流速度与阻力，观察胎儿宫内缺氧及胎儿预后情况。方法随机选择300例孕妇，150例异常妊娠的作为实验组，150例正常妊娠的作为对照组，采用彩色多普勒超声监测脐动脉阻力指标，观察胎儿宫内缺氧及胎儿预后。结果实验组血流动力指标异常，对照组正常。实验组67例出现宫内缺氧，对照组16例出现宫内缺氧，比例分别为44．7％和10．7％，差异有极显著性（P〈0．01）；胎儿出现畸形、IUGR、宫内窘迫等预后不良的比例，实验组均高于对照组，差异有极显著性（P〈0．01）。结论产前监测胎儿脐血流各参数指标，能有效预防胎儿宫内缺氧及预后不良，提高新生儿质量。

Observation on monitoring fetal umbilical blood flow in predicting fetal hypoxia and fetal prognosis

Objective To monitor fetal umbilical artery blood flow velocity and resistance, predicting fe- tal hypoxia and fetal prognosis. Methods 300 pregnant women were randomly selected, with 150 cases of ab- normal pregnancy as the experimental group, and 150 cases of normal as the control group, color Doppler ultra- sound was used in monitoring umbilical artery resistance index and fetal hypoxia and fetal prognosis were ob- served. Results Abnormal hemodynamic indicators found in experimental group and the normal in control group. Of the experimental group, 67 patients had intrauterine hypoxia, 16 patienL~ in control group had in- trauterine hypoxia, with the proportion of 44.7% and 10.7%, resulting in a significant difference （P〈0.01）. Fetal malformations, intrauterine growth （IUGR）, fetal distress and the proportion of poor prognosis in the experimental group were higher, showing a result of a significant difference （P〈0.01）. Conclusions Prenatal monitoring fetal umbilical blood flow parameters indicators can effectively prevent fetal hypoxia and poor prognosis, improve neonatal quality.
