[Increased sensitivity of the bronchial system of hypertensive pregnant patients to beta-adrenergic stimulation].

Airway resistance at term pregnancy was evaluated by oscillation technique in 15 hypertensive and 15 normotensive late pregnant women, and in 10 non-pregnant women. The recordings were obtained before and 1, 3, 6 and 12 min after administration of 0.6 mg Fenoterol by dose aerosol. - The Fenoterol-induced decrease of airway resistance was twice as large in pregnant women with hypertension as in the other two groups.
