[Effect of total parenteral nutrition with different nitrogen burden on organ function and protein metabolism in multiple organ failure rabbits].
Rabbits with MOF induced by intraabdominal sepsis were used to observe the effect of TPN with different amount of amino acid nitrogen on organ function, nitrogen balance and urine 3-MH excretion. The results showed that TPN support could improve the impaired organ function and reverse negative nitrogen balance. Low nitrogen burden was helpful to the lung, while high nitrogen appeared to be beneficial to the liver. Low nitrogen was more effective in increasing nitrogen balance and decreasing the urine 3-MH excretion. We conclude that excessive nitrogen burden results in significant thermic effect and an elevation of stress level, just as excessive glucose does.
