Abstract
The hemodynamics in blood purification (BP) patients with multiple organ failure after surgery was measured 150 times. The 8 patinets in intermittent hemodialysis (group I) and the 6 patients in continuous hemofiltration (group C) were studied and both groups were classified into group I (+) or I (-) and group C (+) or C (-) according to the procedure with or without hypotension during BP. The results were as follows 1) During BP left ventricular stroke work index (LVSWI) and total peripheral vascular resistance index (TPRI) were significantly lowere in group I (+) than in group I (-), LVSWI was significantly lower in group C (+) than group C (-), and TPRI was significantly higher in group C (+) than in group I (+). 2) In group I (-) and I (+) LVSWI was significantly lower during BP than before BP. 3) During BP right ventricular storoke work index (RVSWI) was significantly higher in group C (-) than group I (-). 4) In group I (-) LVSWI was significantly lower after BP than before BP. In conclusion, during BPthe blood pressure was primarily related to left ventricular function and peripheral vascular resistance, the left·right ventricular function and compensatory vasoconstriction were better maintained during BP in group C than in gorup I, and continuous hemofiltration was safer and more useful than intermittent hemodialysis.
