[Correlation of antenatal cardiotocogram and amnioscopy in the management of pregnant women with prolonged pregnancy].

In 125 women whose pregnancy continued for more than the calculated date of delivery 171 CTG were written and the parameters were analysed quantitatively. The lead of the CTG involved an amnioscopy in each case. The findings were compared with each other and with the condition of the newborn. The results show: 1. The normal value for the density of fluctuation-types (given by Rüttgers [15]) exceed in our cases. 2. A significant increase of density for the silent fluctuation-type was demonstrated well overdue of the calculated date. 3. There is no close correlation between the findings of the amniotic fluid and the characteristerics of CTG in excess of the fixed birthdate, even if the newborns show symptoms of overmaturity. The combined application of amnioscopy and prenatal CTG are considered as valuable methods to recognise the fetal risk early in post-term birth.
