Ascorbic acid requirements in postoperative patients.

T T Irvin, D K Chattopadhyay, A Smythe

    Surgery, Gynecology & Obstetrics

    Summary

    Surgical patients show reduced ascorbic acid (vitamin C) levels post-operation. This study suggests increased vitamin C needs and supports supplementation, though its role in wound repair is uncertain.

    Area of Science:

    • Biochemistry
    • Surgical Nutrition
    • Clinical Medicine

    Background:

    • Ascorbic acid (vitamin C) is vital for numerous physiological processes.
    • Surgical stress may impact nutrient requirements, including vitamin C.

    Purpose of the Study:

    • To assess postoperative ascorbic acid requirements in surgical patients.
    • To investigate factors influencing changes in ascorbic acid levels after surgery.

    Main Methods:

    • Measured buffy layer leukocyte ascorbic acid and leukocyte ascorbic acid content in 63 surgical patients.
    • Analyzed correlations between ascorbic acid levels, surgical trauma, blood transfusion volume, and white blood cell counts.

    Main Results:

    • A significant reduction in ascorbic acid levels was observed post-operation.
    • Postoperative changes correlated with white blood cell counts, suggesting leukocytosis influences measurements.
    • Ascorbic acid requirements authentically increased, with a 42% reduction in leukocyte levels by day three.

    Conclusions:

    • Surgical patients exhibit increased ascorbic acid requirements post-operation.
    • Supplementation with ascorbic acid may be beneficial for surgical patients.
    • Postoperative changes in leukocyte ascorbic acid are unlikely to be pathologically significant for wound repair.
