[Suitability of mephentermine for the management of arterial hypotension in pregnancy]

Abstract

10 late pregnant women with hypotension were examined before and after the intravenous injection of 30 mg mephentermin with the method of quantitative sphygmometry, the bloodless graphic registration of the arterial blood pressure and direct electronic timing of pulse wave velocity. Systolic and diastolic blood pressure increase significantly. The cause of this rise in arterial blood pressure is the increase of stroke volume exclusively. Heart rate and total peripheral resistance remain constant. This hemodynamic mode of action is a favourable one in regard to protection of uteroplacental blood flow. Therefore mephentermin is suitable for treatment of hypotension in pregnancy.
