[Can cardiotocography provide information regarding fetal death in utero? Casuistic (author's transl)].

A case of fetal death in utero is discussed in which fetal heart tones were picked up with the cardiotocograph via direct leads from the scalp electrode during labor induction, i.e., during the course of labor. After delivery, however, it was apparent that the fetus had been dead for some time (third grade maceration). Technical errors originating in the instrument itself could be excluded since the instrument was used successfully for other deliveries before and after this particular birth. A defect caused by the scalp electrode was also not possible since the electrode was changed three times.
