Emory Wounds and Lacerations Quizzes with Answers
Verified 100% Correct
what are the 4 phases of wound healing?
1. Hemostasis
2. Inflammation
3. Proliferation
4. Maturation (aka remodeling)
the inflammatory phase focuses on?
destroying bacteria and removing debris (WBC/ neutrophils 24-48 hrs/then macrophages for
several days)
what phase of wound healing is described:
- preparation of the wound bed for the growth of new tissue
- ~4-6 days in duration, associated with edema, erythema (reddening of the skin), heat and
pain
- destryoing bacteria and removing debris
inflammatory phase
what is the focus of the proliferative phase?
fill and cover the wound
what are the three stages of the proliferative phase?
1) filling the wound
2) contraction of the wound margins
3) covering the wound (epithelialization)
the maturation phase lasts from ____ up to _____?
, from 21 days up to two years!; most of the time the way it looks after a year is pretty much it,
predict the worst case scenario.
what phase of wound healing is described:
- new tissue slowly gains strength and flexibility
- collagen fibers reorganize, tissue remodels and matures
- increase in tensile strength
maturation phase (aka remodeling)
what 6 factors affect wound healing?
1) type of wound (linear vs. crush)
2) location; high tension = long heal time
3) extent of wound; depth, nerves, vascular
4) level of contamination
5) estimated length before repair; best within 8 hrs
6) general health status; smoking, DM. age, steroids, etc...
what are the 4 goals in laceration repair?
1) preserve normal fxn
2) achieve best cosmetic outcome
3) least painful approach
4) avoid infection and complications (risk is 1-12% with proper wound care)
Langer's lines
Natural skin lines of minimal tensions;
Incisions perpendicular to them result in larger scars than those parallel to the lines
true or false: pain receptors in skin have no myelin sheath
