[Cardiotocography in intrauterine growth retardation]

Fifty seven cases of intrauterine growth retardation were analyzed at the Department of Perinatal Medicine, "Luis Castelazo Ayala" Hospital, IMSS. The main purpose of the study was to establish the usefulness of cardiotocography in the decision of pregnancy interruption. The patients were divided in three groups in relation to the last non stress test made before delivery (reactive, non reactive, non reactive, non reactive with declarations). It is concluded that cardiotocography is a useful procedure for the surveillance of these fetuses and it was found a good correlation between progressively ominous traces and fetal condition at birth.
