title: Multiple systems organ failure: II. The effect of infusion of amino acids and glucose.
abstract: Amino acids and dextrose infusion were given for short periods of time to a young man whose basal state is characterized in the previous paper in this series, and their effects were documented in terms of plasma concentrations and splanchnic extraction. The basal state measurements show in the acute trauma state and its subsequent starvation state a largely balanced splanchnic extraction of amino acids but at a decreasing rate. Amino acid (FreAmine) infusion at low rates on this background produced a large increase in extraction of a largely balanced mixture of amino acids but a minimal change in glucose release. The septic state is characterized in both the basal and amino acid infusion state by splanchnic extraction of an unbalanced mixture of amino acids which is deficient in branched-chain amino acids and in relative excess of glucogenic amino acids with increased glucose release and increased utilization of amino acids for gluconeogenesis. In early sepsis this state can largely be repaired by exogenous amino acid infusion but in late sepsis can only be partially repaired. The data suggest that the patient in late sepsis should have a branched-chain rich amino acid mixture and that the hepatic failure of sepsis is strongly associated with peripheral release of an unbalanced mixture of amino acids secondary to enhanced branched-chain catabolism. Infused glucose produces a large increase in the plasma glucose but also improves the balance of the splanchnic amino acids extracted. The statistical validity of the preceding statements are examined in detail in the manuscript.
