Skin Closure Techniques & Controlling Bleeding Flashcards
Intraoperative Procedures
4 Goals of Suturing
- Stop bleeding
- Close any dead space
- Approximate the wound edges
- Minimize Scar Formation
Peritoneum would need what type of suture material to close it?
3-0 monocryl (some don’t close this layer)
Fascia may need what type of suture material to close it?
large absorbable suture - 0- vicryl
Deep space (deep dermal) may need what type of suture material to close it?
smaller absorbable - 3-0 vicryl
Skin can be closed by what materials?
subcutaneous suture, staples, or glue
For superficial wounds and delicate tissues (e.g., facial lacerations, mucosal surfaces), use what type of suture?
absorbable sutures - polyglactin (e.g., Vicryl) or polyglycolic acid (e.g., Dexon).
For deeper tissues and those requiring prolonged support, what type of suture do you use?
non-absorbable sutures like nylon (e.g., Ethilon) or polypropylene (e.g., Prolene) are often used.
If the wound is expected to heal rapidly and not require long-term support, what type of suture may be preferred?
absorbable
_____ sutures are used when prolonged support is necessary, such as in cardiovascular or orthopedic surgeries.
Non-absorbable
the Selection of Suture Material and Size depends on what 7 factors?
1) Type of Tissue
2) Healing Characteristics
3) Location of the Wound
4) expected tension
5) size of suture
6) biocompatibility and allergy considerations
7) cost and availability
- If the wound is expected to heal rapidly and not require long-term support, _____ sutures may be preferred.
- _____ sutures are used when prolonged support is necessary, such as in cardiovascular or orthopedic surgeries.
- absorbable
- Non-absorbable
what sutures are preferred in contaminated areas because they are less likely to harbor bacteria?
monofilament sutures - nylon or polypropylene
what sutures may be used in areas where a more flexible suture is needed, such as the scalp?
multifilament
difference between the sutures used for high-tension areas vs lower-tension areas?
- High-tension - stronger; braided polyester (e.g., Ethibond)
- Lower-tension - finer material; polyglactin like Vicryl.
what is the correlation to the number to the diameter size of the suture?
smaller = larger diameter
types of suture allergies
- silk
- catgut
- chromic gut
- nickel
- other metal components - titanium, alloys
- adhesives
Chromic gut sutures are treated with ____ _____ to delay absorption and prolong their tensile strength.
chromium salts
Some sutures, particularly those made of ?, may contain traces of nickel.
stainless steel
Selecting the style of closure is based on:
- Wound size
- Location
- Amount of stress/tension the wound will undergo while healing
Most Common type and easiest to perform suturing technique
simple interrupted
characteristics of simple interrupted suturing
- individually placed and tied
- Allows for eversion of edges
- ONLY for in Low Tension
- ensure every stitch is of equal - helps healing; less scarring
Most commonly used material in simple interrupted?
Nonabsorbable - Nylon or Prolene
benefit of rule of halves for simple interrupted?
Ensures tension is evenly distributed along the wound edges
- better wound healing
- less risk of tissue ischemia or necrosis
- Aesthetically pleasing outcome
- Place sutures again and again without tying each individual suture.
- Easier of the wound is very clean
- Best to help stop bleeding from skin edge - Ex) scalp laceration
