Insulin kinetics in hyperalimentation solution and routine intravenous therapy.

J T Tate, G S Cowan

    The American Surgeon
    |December 1, 1977
    PubMed
    Summary

    Albumin is not needed in parenteral nutrition solutions for stable insulin delivery. A new method ensures predictable insulin infusion, and albumin does not prevent insulin adsorption to surfaces.

    Area of Science:

    • Parenteral nutrition
    • Endocrinology
    • Biochemistry

    Background:

    • Insulin adsorption to containers can affect parenteral nutrition efficacy.
    • Understanding insulin stability in intravenous solutions is crucial for patient care.

    Purpose of the Study:

    • To investigate insulin adsorption in parenteral nutrition solutions.
    • To determine the role of albumin in preventing insulin adsorption.
    • To describe a method for predictable insulin delivery.

    Main Methods:

    • Studied insulin kinetics in protein hydrolysate solutions using double radioisotope tags.
    • Compared solutions with and without albumin.
    • Utilized intravenous saline as a control.

    Main Results:

    • Albumin is not a necessary additive for stable insulin delivery in these solutions.
    • A technique for constant, predictable insulin delivery was established.
    • Albumin does not prevent insulin adsorption to plastic or glass surfaces via protective coating.

    Conclusions:

    • The protective mechanism of albumin against insulin adsorption is not surface coating.
    • Alternative mechanisms should be explored to explain increased insulin concentrations in albumin-containing solutions.
    • The described technique ensures reliable insulin administration in parenteral nutrition.
