Prognostic value of cardiotocographic acoustic test in post-term pregnancies.

The aim of the study was to evaluate the prognostic value of the acoustic test in post-term pregnancies. 80 acoustic tests were done (alkaline phosphatase and oxytocinase). In 12 cases, the cardiotocographic recordings of the acoustic test were described as incorrect, 11 neonates of this were born in asphyxia. In the group of neonates responding to the stimulus correctly, all neonates were born in a generally good state. The results show that the acoustic test is characterized by high prognostic value and a correct test result can predict a good fetal state.
