[Electrolyte studies of the amniotic fluid].
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.
