Evaluation of fetal hypoxia during the 1st stage of labor, based on the combination of Cardiotocography, Fetal Pulse Oximetry and Fetal Doppler Velocimetry, using self-organising…

Aim: The aim of this study is the early and objective diagnosis of fetal hypoxia during labour, based on the simultaneous application and analysis of cardiotocography (CTG), fetal pulse oximetry (FPO) tracings and Fetal Doppler Velocimetry indices. Materials and Methods: Our study included 142 primigravidas in term, with uncomplicated singleton pregnancies. In every case CTG and FPO was used during labour. The Doppler index (PI) was recorded for the descenting aorta (AOR–ΡΙ) and renal artery (RA–ΡΙ) of the fetus. The acid-base balance of the fetus was evaluated with pH and base deficit-Bdecf of the umbilical art…
