The effect of Salbupart on the value of placental perfusion pressure in extracorporeal experiment.
The purpose of the study was determination of the perfusion pressure as an expression of the resistance of placental vascular bed after administration of various doses of Salbupart. In a series of 29 experiments with extracorporeal perfusion of the fetal part of the placental from spontaneous labours after physiological pregnancy it was observed that the medicament given in one dose reduced the vascular resistance in the afterbirth. A beneficial spasmolytic effect of Salbupart may be expected in certain cases of pathological pregnancy associated with increased resting tonus of the placental vessels. The pharmacological management for stimulation of placental adenyl cyclase may be treated as supplementation of deficient endogenous catecholamines enhancing the adaptation mechanisms of the fetus and placenta.
