[Antepartum and intrapartum cardiotocographic changes in pregnant women with diabetes mellitus].

In 69 insulin-dependent diabetic patients antepartal as well as intrapartal CTG's were evaluated retrospectively according to Fischer and Hammacher scores, revealing a marked decrease or a lack of decelerations together with a limitation of the oscillation amplitudes in the antepartal CTG. These show a marked increase during the last weeks of pregnancy. Intrapartal decelerations similar to variable dips are far more frequent. The same alterations, though less marked, are in part also found in latent diabetics. Owing to the small number of patients, and to a lack of literature in this field, no definitive conclusion can be drawn yet. Thus, prospective studies will still have to be carried out on a larger scale.
