[Effect on the cardiovascular system of a 3.5% gelatin infusion solution Gelafusal in hypertensive women in late pregnancy].

Using the method of quantitative sphygmometry with bloodless graphic recording of the arterial blood pressure and direct electronic timing of the pulse wave velocity the behaviour of the cardiovascular system in 10 hypertensive late pregnant women was examined before, during and after the intravenous infusion of 500 ml of a 3,5% gelatinous infusion solution (Gelafusal) given within 30 minutes. There is a mild and transient expansion of the plasma volume. Arterial blood pressure, stroke volume, cardiac output and total peripheral resistance remain constant nearly. Consequently the employment of Gelafusal in hypertensive late pregnant women is possible without making worse the arterial hypertension.
