Aminosyn-PF 7%

Aminosyn-PF 7%, Sulfite-Free, (an amino acid injection — pediatric formula) is indicated for the nutritional support of infants (including those of low birth weight) and young children requiring TPN via either central or peripheral infusion routes. Parenteral nutrition with Aminosyn-PF 7% is indicated to prevent nitrogen and weight loss or treat negative nitrogen balance in infants and young children where (1) the alimentary tract by the oral gastrostomy, or jejunostomy route, cannot or should not be used or adequate protein intake is not feasible by these routes, (2) gastrointestinal absorption of protein is impaired; or (3) protein requirements are substantially increased as with extensive burns.

Dosage, route of administration, and concomitant infusion of non-protein calories are dependent on various factors, such as nutritional and metabolic status of the patient, anticipated duration of parenteral nutrition support, and vein tolerance. See DOSAGE AND ADMINISTRATION for additional information. Central Venous Infusion Central venous infusion should be considered when amino acid solutions are to be admixed with hypertonic dextrose to promote protein synthesis in hypercatabolic or severely depleted infants or those requiring long-term parenteral nutrition.

Peripheral Parenteral Nutrition For moderately catabolic or depleted patients in whom the central venous route is not indicated, diluted amino acid solutions mixed with 5 to 10% dextrose solutions may be infused by peripheral vein, supplemented, if desired, with fat emulsion.

Aminosyn-PF 7%, Sulfite-Free, (an amino acid injection — pediatric formula) is contraindicated in patients with untreated anuria, hepatic coma, inborn errors of amino acid metabolism (including those involving branched chain amino acid metabolism such as maple syrup urine disease and isovaleric acidemia), or hypersensitivity to one or more amino acids present in the solution.

Safe, effective use of parenteral nutrition requires a knowledge of nutrition as well as clinical expertise in recognition and treatment of the complications which can occur. FREQUENT EVALUATION AND LABORATORY DETERMINATIONS ARE NECESSARY FOR PROPER MONITORING OF PARENTERAL NUTRITION. Studies should include blood sugar, serum proteins, kidney and liver function tests, electrolytes, hemogram, carbon dioxide content, serum osmolalities, blood cultures, and blood ammonia levels.

Administration of amino acids in the presence of impaired renal function or gastrointestinal bleeding may augment an already elevated blood urea nitrogen. Patients with azotemia from any cause should not be infused with amino acids without regard to total nitrogen intake. Administration of intravenous solutions can cause fluid and/or solute overload resulting in dilution of serum electrolyte concentrations, overhydration, congested states, or pulmonary edema.
