  • Title: [A study on factors influencing the stability of total nutrient admixture].
    Author: Zhang LH.
    Journal: Zhonghua Wai Ke Za Zhi; 1991 Jun; 29(6):353-6, 396. PubMed ID: 1935432.
    Abstract:
    To study the stability of total nutrient admixture, glucose, amino acid, fat emulsion, electrolyte, and other nutrients in different combinations and concentrations were admixed and infused into 16 3-liter polyvinyl chloride bags, which at last were stored at 4 degrees C, 22-25 degrees C, 32 degrees C, respectively. Samples were inspected at 0, 12, 24 and 48 hours. The results showed that the admixture was stable when total concentration of mono cation was lower than 150 mmol/L, Mg2+ less than 3.4 mmol/L, and Ca2+ less than 1.7 mmol/L, stored at 4 degrees C for 48 hours, or at 22-25 degrees C for 24 hours. We conclude that PVC 3L container is safe for storage of TNA at least within 24 hours.
