A CTG (cardiotocography) is a method of monitoring the fetal heart rate and uterine contractions during pregnancy and birth.
There are two main types of CTGs: analog CTGs and digital CTGs. Here are the differences between the two:
Analog CTG (paper CTG):
In our specialist practice for prenatal medicine, we set the highest standards of fetal monitoring! We use our experience in Doppler sonography and the very best CTG equipment with STV (Short Time Variations) analysis and software, known as Oxford CTGs.
The Oxford CTG is also known as the Dawes-Redman analysis. She has CTG software that should provide more objective data to prevent prenatal misinterpretation of CTGs. The development period was over 35 years at Oxford University. The method is based on the technology with the world’s largest CTGS database and its outcomes. A so-called 100K algorithm contains over 100,000 CTG recordings and their outcomes. We regularly put this worldwide objective computer analysis filtered through our years of clinical experience into practice.
High-risk pregnancies such as those with growth restriction or pre-eclampsia benefit most from this.
Each Oxford CTG is classified as inconspicuous after meeting all the criteria. The following Dawes and Redman analysis criteria apply to all fetuses:
The short-term variation (STV) is the most significant and important parameter in the Oxford CTG. The mini-changes that cannot be identified by the human eye are analyzed. The oscillation is determined over a very short period of time (up to 10 heartbeats). The short-term variations provide information about the blood flow to the fetal brain and thus about the child’s well-being. This value is so reliable that it has been classified as the most important parameter for fatal monitoring in high-risk cases.
A Cochrane Review has already shown a significant reduction in perinatal mortality rates when using a digital Oxford CTG compared to traditional CTG interpretation (Grivell et al., 2015). At the same time, no increased caesarean section rate was recorded thanks to the Oxford CTG.
By using the latest technology, we can provide much better support for our youngest patients and reassure their parents.
