[Relations between the oxytocin test and morphometry of the placenta].
We have studied placental morphometry after delivery in 23 cases in which the oxytocin challenge test was carried out towards the end of the pregnancy. Thus we have been able to compare the results of the two and establish details of placental measurement that have the greatest influence on its function. The following parameters seem to have the most direct influence, by statistical relationship, with placental insufficiency: the total surface of the villi, the concentration of villi per unit sectioned, the surface of fetal capillaries and the mean diameter of these capillaries. On the other hand the mean diameter of the villi and the number of capillaries per villus do not seem to have any relationship to function. These results bring further proof to our old ideas as to the value of placental morphometry and confirm the value of the oxytocin challenge test.
