摘要
Background: Aluminum contamination of parenteral nutrition solutions has been documented for 3 decades. It can result in elevated blood, bone, and whole body aluminum levels associated with neurotoxicity, reduced bone mass and mineral content, and perhaps hepatotoxicity. The primary aluminum source among parenteral nutrition components is glass-packaged calcium gluconate, in which aluminum concentration in the past 3 decades has averaged approximately 4000 mu g/L, compared with <200 mu g/L in plastic container-packaged calcium gluconate. A concern about plastic Packaging is leaching of plasticizers, including phthalates, winch have the potential to cause endocrine (male reproductive system) disruption and neurotoxicity. Methods: Aluminum was quantified in samples collected periodically for more than 2 years from 3 calcium gluconate sources used to prepare parenteral nutrition solutions; 2 packaged in glass (from France and the United States) and 1 in plastic (from Germany); in a recently released plastic-packaged solution (from the United States); and in the 2 glass containers. Phthalate concentration was determined in selected samples of each product and leachate of the plastic containers. Results: The initial aluminum concentration was approximately 5000 mu g/L in the 2 glass-packaged products and approximately 20 mu g/L in the plastic packaged product, and increased approximately 30%, 50%, and 100% in 2 years, respectively. The aluminum concentration in a recently released Calcium Gluconate Injection USP was approximately 320 mu g/L. Phthalates were not detected in any calcium gluconate solutions or leachates. Conclusions: Plastic packaging greatly reduces the contribution of aluminum to parenteral nutrition solutions from calcium gluconate compared with the glass-packaged product.
