Abstract

|
|
Recent interest in the examination of the constituents of amniotic fluid has led to the evaluation of creatinine concentration as a possible index of fetal maturity
This paper reports the results of investigating electrolytes, creatinine, urea, NPN concentration of the.amniotic fluid and maternal serum in normal pregnancy and preeclamsia and eclampsia.
The results were as follows:
1) The mean creatinine concentration of the amniotic fluid of full. term pregnancy was increased significantly but the mean urea and NPN concentration is not significant differences.
2) In pre-eclampsia. and eclampsia, levels of creatinine in the amniotic fluid. were significantly greater than normal valuses, at corresponding periods of gestation. 3) The liquor creatinine concentration always exceed the maternal serum creatinine concentration both in normal and in toxemias of pregnancy.
4) In normal pregnancy sodium concentration of amniotic fluid was decreased at term pregnancy.
5) In pre-eclampsia and eclampsia, the levels of sodium concentration in the amniotic fluid were significantly lower than the levels of sodium of the serum, but the mean cocentration o f potassium and chloride were not significant differnces.
