胎儿脐动脉血流动力学与围产儿缺氧的相关性

Correlation between fetal umbilical artery blood flow dynamics and perinatal anoxia

目的评价胎儿脐动脉(UA)血流动力学与围产儿缺氧的相关性。方法将本院2000-2005年期间,孕龄36～40周,胎儿UA血流频谱异常者29例为实验组,随机抽取同期孕龄胎儿UA血流频谱正常者29例做为对照组。观察参数:UA收缩期血流速度/舒张期血流速度(S/D)及分娩后新生儿阿普加评分。结果实验组新生儿0～3分1例,4～7分5例,8～10分23例,对照组新生儿0～3分0例,4～7分1例,8～10分28例,实验组新生儿缺氧情况与对照组相比具有显著差异(P<0.05)。结论胎儿脐动脉血流检测是预测胎儿宫内缺氧状况的一种安全、有效的检测方法。

Objective To assess the correlation between hemodynamics of fetal umbilical artery and the perinatal anoxia. Methods To observe 29 fetuses whose gestational age range from 36 to 40, and who have abnormal fetal umbilical artery blood flow spectrum from 2000 to 2005 in our hospital as the experimental group. 29 fetuses randomly selected who have the same gestational age and have normal fetal umbilical artery blood flow spectrum as control group. Parameters systolic flow velocity/diastolic flow velocity（S/D） in fetal umbilical artery and total score of Apgar of newborn after delivery. Results Newborn of the experimental group ： 1 Apagar score 0-3,5Apagar score 4-7,23 Apagar score 8-10. Newborn of the control group ：0 Apagar score 0-3,1 Apagar score 4-7,28 Apagar score 8-10. To compare the experimental group with the control group about anaerobic condition, the difference is significant （ P 〈 0. 05 ）. Conclusion Detection the blood stream of umbilic artery is a safe and effective method to predict fetal hypoxic condition in utero.
