Serum immunoglobulins after surgical operations

Y K Chitkara, A B Noronha

    International Surgery
    |March 1, 1977
    PubMed
    Summary

    Longer surgeries significantly decrease immunoglobulin G (IgG) and increase immunoglobulin M (IgM) levels, correlating with higher infection risk. Anesthetic exposure duration may impact these immune changes more than surgical trauma.

    Area of Science:

    • Immunology
    • Surgical Pathology
    • Anesthesiology

    Background:

    • Serum immunoglobulin levels (IgG, IgM, IgA) are crucial for immune function.
    • Surgical procedures and anesthesia can potentially modulate immune responses.
    • Understanding these modulations is vital for managing postoperative outcomes.

    Purpose of the Study:

    • To investigate the impact of surgical duration on serum immunoglobulin concentrations.
    • To explore the relationship between postoperative immunoglobulin levels and surgical infection risk.
    • To identify potential factors influencing immunoglobulins during surgical procedures.

    Main Methods:

    • Serum samples were collected from 38 patients pre- and post-surgery.
    • Patients were grouped based on anesthesia duration (< 2.5 hours vs. > 2.5 hours).
    • Concentrations of IgG, IgM, and IgA were measured and analyzed.

    Main Results:

    • Patients with longer surgeries (> 2.5 hours) showed significant IgG decrease and IgM increase postoperatively.
    • Shorter surgeries (< 2.5 hours) resulted in a slight IgG decrease.
    • A higher incidence of surgical infection was noted in patients with longer operations, correlating with IgG and IgM levels.

    Conclusions:

    • Surgical duration, particularly anesthetic exposure, significantly alters serum IgG and IgM levels.
    • These alterations are associated with an increased risk of postoperative surgical infection.
    • Anesthetic exposure duration appears to be a key factor in immunoglobulin changes, potentially more so than surgical trauma severity.
