The maximum concentrations of phosphate that will remain soluble in a parenteral nutrient solution containing various concentrations of calcium chloride or calcium gluconate were determined. Various concentrations of sodium phosphate were mixed with FreAmine II (McGaw Laboratories), and the resulting solutions were mixed with 50% dextrose solutions(More)
The visual compatibility of 30 drug additives with total parenteral nutrient (TPN) solutions (4.25% amino acids, 25% dextrose injection) was studied. For each drug additive, three TPN solutions were mixed; two were stored for 22 hours at 4 C then allowed to equilibrate to room temperature for two hours. Two 25-ml samples from each TPN solution were examined(More)
Titration curves for total parenteral nutrient (TPN) products were developed and used to determine the amount of alkali needed to make various pH changes. Equations and graphs for determining the titratable acidities of TPN solutions are presented. Samples of five crystalline amino acid products and of 1:1 mixtures of the products with 50% dextrose(More)
A method for quantitating color measurements in dextrose solutions by using a color difference meter is described. This method was shown to correlate well with standard American Public Health Association (APHA) color measurements. A mathematical relationship was developed relating yellowness index values to APHA numbers as described in the USP for dextrose(More)
