Cardiotocography versus Doppler

Randomised controlled trial of cardiotocography versus Doppler auscultation of fetal heart at admission in labour in low risk obstetric population.

OBJECTIVE To compare the effect of admission cardiotocography and Doppler auscultation of the fetal heart on neonatal outcome and levels of obstetric intervention in a low risk obstetric population. DESIGN Randomised controlled trial. SETTING Obstetric unit of teaching hospital PARTICIPANTS Pregnant women who had no obstetric complications that warranted continuous monitoring of fetal hea...

Cardiotocography only versus cardiotocography plus ST analysis of fetal electrocardiogram for intrapartum fetal monitoring: a Swedish randomised controlled trial.

BACKGROUND Previous studies indicate that analysis of the ST waveform of the fetal electrocardiogram provides information on the fetal response to hypoxia. We did a multicentre randomised controlled trial to test the hypothesis that intrapartum monitoring with cardiotocography combined with automatic ST-waveform analysis results in an improved perinatal outcome compared with cardiotocography al...

Cardiotocography during labour.

The importance of antepartum cardiotocography.

The significance of antepartum cardiotocography was examined on patients at the University of Cologne in the years 1982 and 1983. We analyzed 13,310 cardiotocograms of 1,463 women and correlated their pregnancies and deliveries with the status of their newborns. There were only 66 suspect/prepathologic fetal heart rate recordings in 50 patients. All these patients had severe complications durin...

A randomised clinical trial on cardiotocography plus fetal blood sampling versus cardiotocography plus ST-analysis of the fetal electrocardiogram (STAN®) for intrapartum monitoring

BACKGROUND Cardiotocography (CTG) is worldwide the method for fetal surveillance during labour. However, CTG alone shows many false positive test results and without fetal blood sampling (FBS), it results in an increase in operative deliveries without improvement of fetal outcome. FBS requires additional expertise, is invasive and has often to be repeated during labour. Two clinical trials have...
