胎儿窘迫的脐静脉血乳酸测定

Determination of Umbilical Venous Blood Lactate Level in Fetal Distress

本文测定了有胎儿窘迫的27例非妊高征及8例妊高征产妇的脐静脉血乳酸水平,发现非妊高征产妇在胎儿窘迫时,脐静脉血乳酸水平明显增高,妊高征产妇脐静脉血乳酸变化不显。结果表明:妊高征胎儿由于厌氧糖酵解途径障碍,降低了胎儿对缺氧的耐受力。非妊高征产妇在产程不同时期取胎儿头皮血观察乳酸水平变化可作为了解胎儿宫内缺氧的一项生化指标。

Umbilical venous blood lactate level in fetal distress was determined in 8 cases of pregnancy induced hypertension (PIH) and 27 cases without PIH It was found the blood lactate level in fetal distress was significantly higher in the cases without PIH, whereas there was no marked change in the cases of PIH, The results indicate that the commutative power of hypoxia is lower in the fetus of PIH gravidae because of inhibited glycolytic pathway;and that the blood lactate determination by tetal scalp sampling is a good monitoring method for evaluating the presence and severity of fetal distress during labor.
