[The role of an objective assessment of the heart right vientricle function for the anesthesiological maintenance and intensive therapy of surgical patients].

Latent dysfunction of the heart right ventricle and hypovolemia were assessed in 50 patients divided into 4 groups, operated on the heart, abdominal aorta and lungs. It was found that after revascularization of the myocardium the diastolic disorders prevailed. In patients operated for the heart valve (mitral and aortal) diseases prevailing were the systolic and pump dysfunction of the right ventricle. Insufficiency of the right ventricle in these groups was 13% and 22% respectively. After operations on the abdominal aorta a combination of the systolic and diastolic impairments of the right ventricle were observed. After extended resections of the lungs there was a characteristic combination of systolic, diastolic and pump dysfunctions. When the operation was followed by a decreased minute volume of circulation, its cause was hypovolemia in 29% of cases in the examined surgical patients. The investigation of the right ventricle functions with the help of pulmonary arterial volumetry can reveal their latent dysfunctions as well as hypovolemia in a considerable part of surgical patients.
