Continuous Base Excess Monitoring in the Human Fetus
At present, monitoring of the human fetus during labour is performed either by discontinuous monitoring of the fetal heart rate or by cardiotocography supplemented by discontinuous fetal blood analyses of the acid base state if the technique is available. Although these techniques have been available for more than two decades it has not been possible to improve the low specificity of the methods very much. This have caused many discussions and at present there are a wide scale of recommendations concerning fetal monitoring during labour, a scale running from recommending only auscultation through the recommendation of cardiotocography without fetal blood analysis ending up with some centres recommending routine cardiotocography of all parturients combined with fetal blood analysis in 20–30 per cent of all deliveries.
