Placental blood flow is reduced in pregnancies complicated by hypertension, intrauterine growth retardation, maternal smoking, or diabetes. Umbilical-placental production of the potent vasodilator prostacyclin is also reduced in these pathologic states and this deficiency may contribute to an associated increase in the incidence of low infant birthweight by affecting a reduction in placental nutrient transfer. We have studied the effects of the prostacyclin analogue carbacyclin on diffusional transfer in the human placenta perfused in vitro. We have found that carbacyclin crosses the human placenta and can significantly increase diffusional transfer in placenta from pregnancies complicated by hypertension or maternal smoking and in the normal term placenta in which prostacyclin production has first been reduced through the administration of ibuprofen. Carbacyclin had no effect, however, in untreated placenta from normal pregnancies or in placenta from diabetic pregnancies. These results suggest that the prostacyclin-deficient perfused placenta may serve as a model for several placental insufficiency syndromes and that the possibility that prostacyclin analogues may improve deficient nutrient transfer in some pathologic pregnancies warrants further investigation.
