The Role of Cardiotocography in Assessing the Condition of a Fetus in Preeclampsia

What is it about?

The role of cardiotocography (CTG) in preeclampsia is still vaguely defined. The aim of this study was to investigate the possible role of CTG in assessing the condition of the fetus in preeclampsia with and without intrauterine growth retardation (IUGR) and to compare the CTG findings with Doppler parameters and perinatal outcome.

Why is it important?

The prospective study included 30 singleton pregnancies with preeclampsia completed by Caesarean section. The study group was divided into subgroups based on the presence of IUGR in relation to the severity of preeclampsia. The control group consisted of 20 healthy women delivered by elective Caesarean section. In 53.3% of preeclamptic cases, cardiotocographic findings differed from normal (p<0.001) and was a warning or pathological. There were no significant differences in the presence of a pattern deviated from normal based on the severity of preeclampsia, and it was significantly more prevalent in preeclampsia with IUGR (p<0.01) than the one without it. The prevalence of CTG pattern types in the study group is significantly altered by presence of olygoamnion (p<0.05) as well as the parameters of the flow through the uterine arteries, umbilical artery and middle cerebral artery (p<0.05). Apgar score significantly depends on the CTG findings and decreases with the onerous CTG pattern.
