title: [Creatinine during pregnancy (author's transl)].
abstract: Determination of the creatinine concentration of the amniotic fluid was undertaken between the 25th and 40th week of gestation in 114 patients. The normal serum creatinine level was simultaneously determined in 43 of these patients. The aim of this study was to examine whether this parameter of fetal renal function allows a conclusion to be drawn with respect to fetal maturity and the length of gestation. With increasing length of gestation a marked increase in the amniotic fluid and the maternal serum creatinine concentration was observed (p less than 0.01). The large scatter of the values made it impossible to relate any particular creatinine concentration to a certain week of gestation. However, if the concentration of creatinine in the amniotic fluid has reached a value of 2 mg% or more, a mature baby can be predicted in most cases. A tendency to raised levels of creatinine was seen in cases of EPH gestosis and latent diabetes mellitus. The determination of creatinine in the amniotic fluid can be recommended with certain reservations as an additional method to assess fetal maturity.
