Place du rythme cardiaque fœtal et de son analyse informatisée dans la surveillance de la grossesse prolongée

In the case of fetal surveillance in prolonged pregnancies without risks associated, evidence is lacking to attest that the use of visual and computerized CTG analysis improves perinatal prognosis. CTG plays all the same a dominating role in surveillance programs and remains used in the first intention. The contraction stress test and the fetal vibroacoustic stimulation test have not demonstrated their usefulness in this indication.
