[Effects on the normalization of amino acids in metabolic support for trauma surgical patients]

Both serum and muscle intracellular amino acids pattern are changed after trauma. The formulation of amino acid solutions is important for the balance of the patient's serum or intracellular amino acids. In 45 gastric cancer patients after total gastrectomy, the efficacy of individualizal amino acid solution (IDAA) was compared with that of other two balance amino acid solutions. The result showed that metabolic support with IDAA could decrease the muscle intracellular phenylalanine level and increase the levels of free neoglycogenic amino acids, arginine and ornithine both in serum and muscle cells. It is beneficial to the early recovery from trauma and normalization of serum or muscle amino acids pattern.
