[Comparison of transcutaneous oxygen pressure measurement with computer automatic CTG analysis sub partu].

514 labors from 20 tcpO2-cardiotocograms with about 10 000 events were computerized. By means of tcpO2-measurement we found a higher correlation between the fetal condition basing on a discriminant function (DF) than to the quantitative solitary parameters (residual-bradycardia, fetal heart frequency, dip area, lag time and bradycardia-index). The boundary ranges from the quantitative CTG-interpretation: "normal", "praepathological" (warning signs) and "pathological" (hypoxie signs) were confirmed for practice. The tcpO2-curve basing on quantitative analysis of their parameters (base line, slope of pO2 referring to labors and the delay time) is good adapted for examination of solitary CTG-parameters in relation to clinical practice.
