[Mechanisms of enteral correction of posthemorrhagic hypovolemia]

It has been demonstrated in chronic experiments that after hemorrhage liquid absorption from the small intestine does not interfere with the process of its supply from the interstice. Totally both these processes considerably enhance the degree of autohemodilution. Infusion of the electrolyte monomer solution to the duodenum of the dogs which suffered hemorrhage (20-50 ml/kg bw) ensure, during the preserving of absorption function, a rapid and stable growth of the circulating plasma volume, proteins, sodium and potassium, being an effective means of steady replenishment of posthemorrhagic hypovolemia. Reduction of water-retaining plasma components discovered in the experiments attests to the participation of the digestive organs in formation of the basic volemia substrate water-protein-electrolyte in volemic homeostasis maintenance.
