Computerassistierte Analyse von intrapartalen Kardiotokogrammen

Adequate quantification of only three variables of FHR using a score leads to fairly good correlations with parameters of the fetal acid-base balance. Thus actual pH (UA) can be predicted in reasonable clinical limits. Still present variability in prediction of pH seems to be, in part, of maternal origin. The maternal influence could be eliminated by continuous (transcutaneous) monitoring of maternal pCO(2). Along these lines the quantitative electronic monitoring of FHR will be realized and instrumented (off-line and on-line) by nexus/gmt, Frankfurt, a.M., Germany.

“…Diese Erkenntnis musste Anlass sein, die Herzfrequenzphänomene des Feten völlig zu ¹computerisierenª, d. h. ihre Bewertung ganz einem Rechner zu überlassen, der irrtums-und ermüdungsfrei diese Aufgabe ± auch im Echtzeit-Betrieb ± wahrnehmen kann. Dieser Schritt war groû und alles andere als einfach [8,10].…”

“…Due to clinical habits baseline FHR is separated mentally from decelerations because usually the mean frequency niveau during a dip is not determined. Dip-area and its duration as well as its amplitude ('Lost beats' [ 15 ] ) are more predictive parameters [ 16 ] . Computer analysis of the FHR off ers the opportunity to separate baseline FHR from deceleration patterns using appropriate MATLAB-algorithms rearranging and sequencing all baseline partitions (or all decelerations) to a new fi le.…”

Quantitative CTG-Bewertung sub partu mit einem neuen CTG-Score: Wie gut sind die Korrelationen mit den Parametern des fetalen Säure-Basen-Haushaltes im Nabelschnurblut?

2003

The good correlations of the variables of the fetal acid-base balance with the CTG phenomena registered with the score can be used for clinical purposes. However, analysis of the CTG with the naked eye is not practically feasible for the obstetricians; it must therefore be done per computer. Quantitative CTG analysis has created the perspective of a promising new method for fetal monitoring sub partu.
