Computerized fetal heart rate monitoring subpartum as a predictor for extreme fetal outcome

Objective: We investigated to what extent subpartum computerized fetal heart rate analysis according to the FIGO criteria can predict fetal outcome. Additionally, we aimed at identifying factors which might be able to explain extreme differences between CTG classification and the actual fetal condition at delivery. Methods: We screened all 3.380 births from 2000–2002 for extreme good and extreme poor outcomes defined by umbilical artery pH, base deficit and the apgar-score. General boundery conditions for both groups were single fetuses of ≥37 weeks gestational age, vaginal delivery and a CTG record of ≥30min du…
