Artificial gut for total parenteral nutrition through the peritoneal cavity

Total parenteral nutrition was attempted by using the peritoneal route. In this way it was possible to convey to the patients all elemental nutrients used in hyperalimentation. Three patients were studied while treated for an episode of catabolic stress in the course of acute or chronic uremia. Adequacy of treatment was controlled by measuring urea generation rates, plasma concentrations of 3-methyl-histidine, glucose disappearance from dialysate and kinetics of lipid particles removal from plasma. The data collected demonstrate that peritoneal hyperalimentation is is feasible for adequate for clinical purposes.
