The obstetrician does not pay attention to electrolytes in the amniotic fluid inspite of its great significance in the fetal homeostasis since its disturbance causes quick death of the fetus. In the presented article we aimed not only to describe reference values of sodium potassium, chloride and calcium but to examine their changes in prepathological and pathological states. 135 women with changes in the course of pregnancy of various character were investigated as well as 200 control women with normally progressing pregnancy. The results showed that there was steady state in the concentration of the indicated electrolytes during the whole pregnancy. There were no statistically significant changes in electrolyte concentrations neither in preterm or prolonged pregnancy, nor in acute or chronic fetal asphyxia, in meconial and hematinic mexures samples as well as in oxytocin infusions with a medium of saline. There was only highly significant lowering of the amount of calcium ions in the amniotic fluid of women with pre-eclampsia. Analysis of the results show that the kidney, finding itself in functional correlation with the placenta, is reliable regulator of the internal and external homeostasis of the fetus.
尽管羊水电解质对胎儿内环境稳定具有重要意义，因为其紊乱会导致胎儿迅速死亡，但产科医生却并不关注羊水电解质情况。在本文中，我们不仅旨在描述钠、钾、氯和钙的参考值，还旨在研究它们在病理前期和病理状态下的变化。我们对135名孕期过程有各种变化的女性以及200名孕期正常进展的对照女性进行了调查。结果显示，在整个孕期中，所提及的电解质浓度处于稳定状态。在早产或过期妊娠、急性或慢性胎儿窒息、胎粪和血性羊水样本以及生理盐水介质的催产素输注中，电解质浓度均无统计学上的显著变化。只有子痫前期女性羊水中钙离子含量有极显著降低。结果分析表明，与胎盘存在功能关联的肾脏是胎儿内外环境稳定的可靠调节者。
