[Continuous monitoring of mixed venous oxygen saturation during mechanical circulatory support of the left ventricle in heart surgery patients. Pathophysiologic principles and personal experience].
The clinical use of mechanical supports for cardiocirculatory function assistance has permitted to treat a higher number of low output syndromes insensitive to pharmacological therapy. One of the most important problems arising during mechanical circulatory assistance, is the ability to know if the performance of the artificial device is adequate to match metabolic tissues demands. Continuous monitoring of mixed venous O2 saturation (MSvO2) has been proposed as the most complete and reliable tool to verify this correlation. The Authors analyse the problems connected with this kind of monitoring during left ventricular assistance with centrifugal pump in cardiosurgical patients and present 6 cases taken from their clinical experience.
