Forty-eight patients was applied on the study. The hemodynamic parameters were measured with the thermodilution technique. The mean arterial pressure (MAP), the pulse (F), the cardiac output (CO), the pulmonary wedge pressure (PCWP), the systemic vascular resistance (SVR), the left and right ventricule work-index (LVSWI, RVSWI) were measured, The oxygen delivery and consumption (DO2, VO2), the serum lactate level were estimated. The inflammatory parameters - C-reactive protein, procalcitonin, white blood cell - were controlled daily. The laboratory tests of fluid balance and inonogram (Na, K in the urine), the clinical signs (temperature, consciousness, APACHE II score) were assessed daily.
