3 Wound Closure Flashcards
5 wound closure techniques
- Suture
- Staples
- Tissue adhesives
- Adhesive tapes
- Hair apposition
Wound closure technique with greatest tensile strength
Sutures
- also with lowest dehiscence rate
Wound closure technique with lowest infection rates
adhesive tapes
- also least tissue reactive
Wound closure technique with greatest tissue reactivity
Sutures
- also with highest cost and slowest application
Wound closure technique with highest rate of dehiscence
Adhesive tapes
Nonabsorbable sutures retain their tensile strength for
at least 60 days
5 types of nonabsorbable sutures
- Silk
- Nylon
- Polypropylene
- Polyester
- Polybutester
Nonabsorbable suture with least tissue reactivity
polypropylene
Nonabsorbable suture with significant inflammatory reaction
silk
Nonabsorbable suture that’s used for intraoral mucosal surface
silk
Nonabsorbable suture that’s used for tendon repair
polyester
Nonabsorbable suture that’s used for skin approximation
nylon and polypropylene
Nonabsorbable suture that’s used for soft tissue reapproximation
nylon, polypropylene, and polybutester
suture sizes per laceration location
Face: 6-0
Digits: 5-0
Extremities: 4-0
Trunk: 4-0
Scalp: 4-0 or 3-0
The larger the suture size number, the thinner the suture (and the lower the tensile strength)
How to determine the number of square knots to be done
the number of knot ties should correspond to the suture size (i.e., four ties for a 4-0 suture, five ties for a 5-0 suture, etc)
Additional ties do not increase the strength of a properly tied square knot; they only add to its bulk
The extra ties are to increase knot security and prevent unraveling
