Where Does the Aluminum in HPN Come From?
The amount of aluminum contamination in an HPN solution can vary widely depending on the amount and type of additives it contains, as well as the age of the additives. As seen below in the sample HPN formulation for a 68kg patient, the largest contributors to aluminum contamination are potassium acetate (K Ac), calcium gluconate (Ca++), and to a lesser extent, sodium phosphate (NaPO4).
