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
