本文检测了15例正常产妇产前、产时及产后血浆地高辛样免疫活性物质(DLIS)的水平。结果产前与非孕期健康对照组相比无显著性差别,产时及产后即刻较临产前明显升高(p<0.01),而产后24小时已降至产前水平。推测产时母体血浆DLIS水平的升高可能与产痛等应激因素有关;产后即刻的高水平可能是产时的延续或/和大量子宫血液进入母体循环使心脏负荷加重有关,提示产时及产后24小时内血浆DLIS水平的监测对了解产妇的应激程度和心脏负荷情况具有一定的指导意义。
In this paper, the levels of plasma digoxin-like immunoreactive substance (DLIS) in 15 normal pregnant women were examined before delivery, during delivery and after delivery. Results There was no significant difference between prenatal and non-pregnant healthy controls. The prenatal and postnatal period were significantly higher than prenatal (p <0.01), and decreased to prenatal level 24 hours after delivery. It is speculated that the rise of maternal plasma DLIS during labor may be related to the stress factors such as labor pain. The immediate postpartum high level may be the continuation of labor hours or / and a large number of uterine blood into the maternal circulation to increase the heart load, The monitoring of plasma DLIS level within 24 hours after delivery is of guiding significance for understanding the degree of stress and heart load of maternal.
