Sensitivity, specificity, receiver-operating characteristic (ROC) curves and likelihood ratios for electronic foetal heart rate monitoring using new evaluation techniques.
Hypoxia and acidosis adversely influence many foetal organ functions. We wanted to know how foetal heart rate (FHR) patterns are mirrored by the fetal acid-base status and if they could serve for predicting the actual pH in umbilical artery (UA) blood. For this purpose we condensed the FHR phenomena into one figure which was to be used as a testing variable and to analyse the performance of the new testing procedure. ⋯ Computer-aided evaluation of FHR patterns leads to a novel index (WAS score) which predicts foetal acidaemia with a high level of accuracy. Therefore online WAS scoring is proposed as an ancillary test procedure for future evaluation of FHR patterns. The conventional EFM remains untouched.
