Glutamate-containing parenteral nutrition doubles plasma glutamate: A risk factor in neurosurgical patients with blood-brain barrier damage?

1999

OBJECTIVES: Animal studies have shown that the elevation of plasma glutamate levels increase cerebral edema formation whenever the blood-brain barrier is disturbed. Therefore, changes in plasma glutamate levels as influenced by the administration of a glutamate-containing amino acid solution were investigated in neurosurgical patients. DESIGN: Prospective, descriptive study. SETTING: Eight-bed neurosurgical intensive care unit in a university hospital. PATIENTS: Twenty-three neurosurgical patients requiring parenteral nutrition. INTERVENTIONS: Parenteral nutrition was begun 24 hrs after craniotomy. Patients receiving a glutamate-containing amino acid solution (3.75 g/L glutamate) were compa…
