Suture resistance to infection

W V Sharp, T A Belden, P H King

    Surgery
    |January 1, 1982
    PubMed
    Summary

    Synthetic sutures, particularly monofilament types, demonstrated superior resistance to gram-positive and gram-negative infections compared to natural sutures in a mouse model. Lubricating coatings did not impact infectibility.

    Area of Science:

    • Surgical Materials Science
    • Infectious Disease Research
    • Biomaterials Engineering

    Background:

    • Suture materials have evolved significantly with the introduction of synthetic absorbable and nonabsorbable options.
    • Assessing the infectibility of various suture materials is crucial for wound management and infection prevention.

    Purpose of the Study:

    • To evaluate the comparative resistance of 16 natural and synthetic suture materials against gram-positive and gram-negative bacterial infections.
    • To determine the influence of suture type (natural vs. synthetic, monofilament vs. multifilament) and coatings on infectibility.

    Main Methods:

    • A total of 420 suture implants were performed in the Edlich mouse model.
    • Sixteen different suture materials were tested against gram-positive and gram-negative infections, with comparisons to appropriate controls.
    • Infectibility was graded to assess the performance of each suture type.

    Main Results:

    • Synthetic suture materials exhibited superior performance in resisting infection compared to natural sutures across all tested categories.
    • Monofilament synthetic sutures demonstrated better resistance to infection than multifilament synthetic sutures.
    • Lubricating coatings applied to sutures showed no discernible effect on their infectibility.

    Conclusions:

    • Synthetic sutures are recommended over natural sutures for use in wounds with a potential for infection due to their superior antimicrobial resistance.
    • Monofilament synthetic sutures represent a favorable choice for minimizing infection risk in surgical wound closure.
