The study was carried out on 48 human placentas perfused in vitro. Betamethasone was administered into the arterial system in the following single doses: 0.4 mg, 2 mg, 10 mg. It was found that betamethasone decreases the pressure of perfusion in different ways depending on the dose. A statistically significant decrease in perfusion pressure was observed in 30th minute of the experiment after administering 2 mg while a dose of 10 mg induced a significant perfusion pressure in 30th and 60th minute of the experiment. The relaxation of the blood vessels of the placenta under the influence of betamethasone was attributed to the action of dopamine on the dopaminergic receptors of the vessels and glucocorticoids modifying this action. The results of the experiments point to a positive action of betamethasone on the blood vessels of human placenta.
