Study Notes
Sutures and their Applications
- Sutures are materials used for tissue repair and wound healing, also known as ligatures when specifically occluding vessels.
- Historically, sutures were threaded through needles by scrub nurses; now, most are swaged, reducing the risk of sharps injuries.
- Key factors affecting suture selection include tissue type, operation specifics, patient condition, infection risk, and surgeon preference.
Suture Characteristics
- Preferred sutures are sterile, versatile, minimally traumatic, handle easily, secure well when knotted, possess high tensile strength, exhibit favorable absorption profiles, and resist infection.
- Suture size, measured as diameter or gauge, is visible on packaging alongside expiry dates (typically five years from manufacturing).
Types of Suture Materials
-
Absorbable Sutures:
- Flexible strands derived from collagen or synthetic polymers, absorbed by the body.
- Common types: Surgical gut (Chromic), Vicryl (Ethicon), Polysorb (Covidien), Dexon.
-
Non-absorbable Sutures:
- Material resists enzymatic digestion and is not metabolized by the body.
- Common types: Silk (Sofsilk), Nylon (Monosof), Polypropylene (Prolene), stainless steel.
Absorbable Suture Details
- Surgical gut can be natural (bovine-based, requires immediate use upon opening).
- Synthetic types include Vicryl (braided, good knot security) and Monocryl (monofilament, excellent tissue passage).
Non-absorbable Suture Details
- Silk is high-reactivity not for infected areas; stainless steel provides extreme strength with poor tissue passage.
- Non-absorbable sutures are ideal for skin closure and long-term tissue repair due to higher healing time.
Suture Needles
- Understanding needle anatomy is crucial: point (sharp end), swage (connection of suture and needle), body (shaft).
- Types of needles include eyed, French eyed, and swaged (most common).
- Needle points vary: taper (rounded), cutting (sharp edges for tough tissue), and blunt (safe for delicate organs).
Threading and Loading Sutures
- Free needles can be threaded manually; swaged needles require no threading.
- Check needles and sutures for completeness and functionality prior to use.
- Manual straightening of certain suture types is necessary before needle loading to prevent fraying.
Safety and Best Practices
- Always guard the return of needles and pass forceps to the surgeon's non-dominant hand during suturing to minimize injury risks.
- Prepare straight mayo scissors for suture cutting post-knotting to maintain a smooth surgical workflow.
