[Biophysical activity of the fetus during labor in EPH-gestosis].

Fetal respiratory and motor activities were studied in 105 parturients with EPH gestosis of varying severity and in 25 reference ones. The results evidence that, in contrast to the antenatal period, normal fetal condition in labor is associated with biophysical inertness, this fact confirming the known viewpoint on the intranatal fetal hibernation. Active management of labor in parturients with doubtful and abnormal biophysical parameters on the eve of delivery impairs the natural mechanisms of fetal defense in labor. Respiratory or motor activity of the fetus should be regarded as a prognostically unfavorable sign in respect of hypoxic involvement of the CNS and the newborn aspiration syndrome.
