[Partial and complete correlations of fetal maturity with ultrasonographic and enzymatic measurements]

The computer-aided enzymatic and ultrasonographic method of pregnancy monitoring takes into account ultrasound measurements of fetal parameters (BPD, HC, AC, FL) and oxytocinase (CAP1) and isooxytocinase (CAP2) levels in maternal blood. In this paper we decided to verify which one of this values have the major influence on fetal maturity prediction. 385 pregnancies, after sterility treatment, were studied where ultrasound measurements and enzymes levels were estimated simultaneously as well as current fetal maturity were established using computer-aided method by M. Klimek. There are high sample correlations between current fetal maturity and the number of remaining days to labor (r = -0.8) as well as ultrasound measurements (BPD r = 0.87, HC r = 0.89, AC r = 0.90, FL r = 0.81). Fetal maturity correlations with enzymatic values (CAP1, CAP2) were smaller 0.55, 0.52 respectively. The partial correlation pictures this relations much stronger -0.29, 0.28, 0.22, 0.30, 0.46, -0.06, 0.13 respectively.
