Brief summary
ST-analysis of the foetal ECG (STAN®) is another second line technique for intrapartum foetal monitoring. Combining ST-analysis with standard CTG interpretation aims to identify hypoxic foetuses more accurately than CTG alone. The STAN® method identifies changes in the ST-interval of the foetal ECG that occur in the presence of foetalcentral hypoxia The aim of this studie is to investigate if the foetal lactate blood sampling is still useful when STAN® monitoring is already being used as a second line technique for intrapartum foetal monitoring if the fetal heart rate is abnormal without a significant ST event Nowadays in the Montpellier hospital's protocol, the investigators have to check the value of lactate sampling in case of le STAN doesn't detect an ST event. So this studie can change the Montpellier hospital's protocol and avoid useless fetal blood sampling
