The aluminum content of parenteral solutions: current status.
Aluminum contaminates several chemical compounds that are administered intravenously to patients. The most highly contaminated are calcium and phosphate salts, followed by albumin and heparin. Parenteral administration of aluminum bypasses the gastrointestinal tract, which serves as a protective barrier to aluminum entry into the blood. In the past, parenteral administration of aluminum as a contaminant of water used in hemodialysis and of casein hydrolysate, the former source of protein in parenteral nutrition solutions, was associated with a low-turnover osteomalacic bone disease and, in the case of uremic patients, encephalopathy. Groups currently at risk for aluminum accumulation in tissue resulting from parenteral administration include premature infants receiving long-term parenteral nutrition and patients receiving plasmapheresis therapy with albumin. Both groups may develop metabolic bone disease; the pathogenesis may involve aluminum. The Food and Drug Administration is currently considering regulation of aluminum in fluids used for parenteral nutrition. No changes are presently proposed with regard to albumin.
