In 77 women (phi 41 week, less than 7 days before delivery) we compared the resistance index (RI) in the umbilical artery (UA), descending aorta (DA) and intracranial artery (ICA) with an oxytocin challenge test (OCT) and a non stress test (NST). Proof criterias were asphyxia resulting in operative deliveries and metabolic acidosis. The sensitivity in predicting metabolic acidosis was low in all tests, but a high and comparable specificity could be achieved in both the RI and OCT. In predicting fetal asphyxia the RI in the ICA had a high sensitivity, the RI in the UA and DA had the highest specificity of all tests. Centralisation and increased brain perfusion seem to detect fetal asphyxia as a result of placental insufficiency.
在77名女性(孕41周,分娩前不到7天)中,我们将脐动脉(UA)、降主动脉(DA)和颅内动脉(ICA)的阻力指数(RI)与催产素激惹试验(OCT)和无应激试验(NST)进行了比较。验证标准为导致手术分娩和代谢性酸中毒的窒息。所有测试中预测代谢性酸中毒的敏感性都较低,但RI和OCT都能达到较高且相当的特异性。在预测胎儿窒息方面,ICA中的RI敏感性高,UA和DA中的RI在所有测试中特异性最高。集中化和脑灌注增加似乎能检测出由胎盘功能不全导致的胎儿窒息。
