patient management Flashcards
phases of wound healing
Phase of inflammation (2-3 days)
phase of profileration (3days-3weeks)
phase of remodelling (3wk - 2yrs)
Granulation
eventually new epithelium will be able to grow across the defect
W.B.P
Wound bed preparation
purpose of W.B.P
identify and remove barriers to healing
focused on managing the wound healing processes of wound extudate, bioburden and devatilised tissue
wound healing can be classified by
Tissue integrity aetiology (how) time since the trauma degree of contamination these will influence the choice made with regards to how a wound will be treated
Tissue integrity
open wound
closed wound
Aetiology
Abrasion/graze avulsion/degloving incision laceration puncture burns
Class 1 0-6 hour
minimal contamination
class 2 6-12 hours
significant contamination
class 3 12+ hours
gross contamination
Factors affecting wound healing
vascular supply and haemostasis
dead space
systemic or physiological factors
healing method (1st 2nd 3rd intention wound heraling
surgical techinique
infection foreign material/necrotic tissue
mechanical stress
primary healing (first intention)
clean incised wound or surgical wound
more epitelial regeneration then fibrosis
wound heals
rapidly with complete closure
secondary healing ( second intention)
occurs in a wound with extensive soft tissue loss
heals slowly with fibrosis
it leads into a wide scar, often hypertrophed and contracted
healing by third intention
these occur in wounds that are left open for debridement
after debridement and control of infection, wound is closed with sutures.
primary closure
immediate closure
clean or clean contaminated wounds
