[The use of apressin in patients with pulmonary tuberculosis and functional disorders of the external respiration and hemodynamics].

Effects of apressin, a peripheral vasodilator, on external respiration function and central hemodynamics was studied in 51 patients with pulmonary tuberculosis. The study showed that a single administration of 20 mg apressin in pulmonary tuberculosis patients failed to bring about any changes in both external respiration function and blood gases, only causing a minor shift in the buffer bases. Systolic pressure in the pulmonary artery remained unchanged after a single 20 mg dose of apressin was given. A statistically significant decrease in total pulmonary vascular resistance and an increase of the central hemodynamic values in pulmonary tuberculosis patients with hypokinetic type of circulation are recorded.
