    Study Notes

    Suturing Essentials

    • To suture, we need a needle and thread

    Needle Anatomy

    • The anatomy of a suture needle consists of an eye, body/shaft, and point

    Classifications of Needles

    • According to eye: threadable/eyed or swaged/unthreadable
    • According to body/shaft: varying shapes and sizes
    • According to needle point: various types

    Correct Suture Needle Loading

    • Important for efficient suturing

    Suturing Threads

    • Properties of an "ideal" suture material:
      • Easy for the surgeon to handle
      • Provide appropriate strength and secure knots
      • Can tolerate wound changes like swelling and recoil
      • Minimal drag: frictionless along the surface to glide through tissue
      • Complete breakdown with no residue
      • Inert: cause minimal tissue reaction, inflammation or infection risk
      • Easily visible
      • Relatively inexpensive
    • Note: There is no ideal suture material

    Considerations for Choosing Sutures

    • Tensile strength
    • Tissue reactivity
    • Drag
    • Capillarity
    • Knot security
    • Memory
    • Plasticity
    • Elasticity

    Classifications of Suture Materials

    • Absorbability:
      • Absorbable
      • Non-absorbable
    • Origin of material:
      • Natural/Organic
      • Synthetic
    • Structure of material fibers:
      • Monofilament
      • Multifilament
        • Braided
        • Twisted

    Absorbable Sutures

    • Broken down and absorbed by enzymatic degradation, phagocytosis, and hydrolysis
    • Lose majority of tensile strength within 60 days

    Non-Absorbable Sutures

    • Remain intact
    • Tissue response is encapsulation and fibrous engulfment
    • Retain tensile strength
