[Cardiovascular and metabolic effects in nebulizer therapy of bronchial asthma]. / Kardiovaskuliatornye i metabolicheskie éffekty pri nebulaizernoi terapii bol'nykh bronkhial'noi astmoi.

The aim of the study was examination of cardiovascular effects of nebulizer salbutamol (ventolin) therapy of bronchial asthma (BA). The efficiency of the drug was assessed in 38 BA patients by changes in clinical symptoms and rise of peak volume expiration rate. Before and after ventolin treatment (2.5-5 mg), measurements were made of central hemodynamics, microhemodynamics, cardiac arrhythmia, plasma electrolytes. The results of the tests indicate that nebulizer treatment with ventolin effectively and safely eliminates bronchoobstructive syndrome in BA patients. Systolic and diastolic arterial pressure, left ventricular end diastolic pressure, ventricular extrasystole declined, supraventricular extrasystole rose. Microcirculatory effects were both positive and negative. Plasma concentration of potassium ions reduced insignificantly.
