PRINCIPLES OF WOUND CARE Flashcards
Name some basic components of aseptic technique
hygiene use of PPE use of sterile feild opening and introducing packets w/out contamination not touching non sterile items
3 components of a well managed wound
well vascularized (not dead or foreign stuff)-debrided
clean (sterile fluid)-irrigation
moist- dressed w/ impregnated layer, then dry layer
define a clean wound and its TX
Uninfected, operative wound, no infl., no Resp/GI/GU. Primarily closed, no abx.
define a clean-contaminated wound and its TX
Operative wound Rsp/GI/GU inv. in cntrld cndtns, debride, irrig, 1rst clos, Cefazolin/Cefotetan
define a contaminated wound and its TX
Trauma (exp. To FB), GI spillage, infl. Encountered. Debride, irrig, 2nd clos. Cefazolin/ofloxacin
define a dirty-infected wound
Old traumatic wounds, active infection. Debride, irrig, 2nd clos, Augmentin.
when is primary closure indicated?
• Primary: clean wound, deep enough to leave excess scar if not closed, suture->hairline scar
When is secondary closure indicated?
gaping, irregular wound, dirty >18hrs-
When is tertiary closure indicated?
wound that is greater than 18 hours. This is a judgement call for wounds that may be infected, but would ideally be closed for cosmetic or functional purposes. clean and debride, allow granulation and reassess in 4-5 days.
When is closure contraindicated
never close infected wounds: FB, contam, puncture, crush, abscess, sig. delay
