[Personal observations of dobutamine effectiveness after surgery with extracorporeal circulation]. / Wlasne spostrzezenia w stosowaniu dobutaminy po operacjach w krazeniu pozaustrojowym.

This report describes the use of dobutamine in patients presenting a low output syndrome after cardiosurgical operations i EEC. Of 565 patients operated on valvular heart defects and coronary artery disease in 89 patients (15.7%) a low output syndrome was diagnosed and treated. Dobutamine proved to be effective in patients with moderate impairment of the left ventricular contractility. In those with severe left ventricular dysfunction, dobutamine was ineffective and other catecholamines ought to be used. The authors support the view that combined administration of dobutamine (or other catecholamines) and nitroglycerin in patients with low output syndrome proves to be superior to the effect of each single drug.
