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
delayed primary closure
closure 2-3 days post trauma
allows elimination of exudate +/- contamination
identification of non viable tissues
clean contaminated or contaminated wounds
Factors affecting wound closure decision
wound classification timing of injury -/+ 6 hours foreign body contamination bacterial contamination cause of injury viability of tissues (blood supply) availabilty of tissue location of wound - potential of tension cost
common household poisons
Chocolate, panadol, rat posion, alcohol, grapes, pesticides, insecticides.
Purpose of first aid
to help in an emergency situation And immediate treatment of injured animals.
limitations of first aid
noone is allowed to practice veterinary surgery unless they are registered in the veterinary surgeons register
arterial vs venous bleeding
arterial bleeding occurs in the arteries. (carries blood from heart to body) venous bleeding happens in the vein which carries blood back to heart
first aid procedure for haemorrhage
stop the bleeding apply pressure with the palm of your hand to the wound until bleeding stops.
Heatstroke
Apply or spray tepid cool water not cold onto their fur and skin. put animal into a cool shaded area.
Road traffic accident
move animal to safety if you can, but make sure no broken bones first. check for bleeding or signs of wounds. keep warm with blankets. venitlation if having trouble breathing
Class 1 emergencies
Catastrophic, life threatening. requires immediate attention, respiratory failure, heart failure,
Class 2
Very severe, requires attention within minutes to an hour, multiple injuries, shock and bleeding
class 3
Serious urgent, requires attention within a few hours,
Class 4
less serious but still requires attention within 24 hours
bandaging considerations
possibly keeping animal in clinic especially if the owner is not able to change regularly being older, if chews can use ecollar or pool noodle, or a baby onesie to keep it clean.
layers of bandaging
absorbant pad, soft ban, compression bandage, vet wrap elastoplast
layers of bandaging
absorbant pad, p soft ban, offers cushioning and protection to help with healing process, compression bandage, to help prevent swelling. vet wrap, elastoplast provide stability for dressings to stay in correct position
idiopathic
unknown origin
ascite
excess abdominal swelling
jaundice
yellowing of mucous membranes (liver)
Hyper/Hypothermia
temperature is too high, temp is too low
Hyper/hypo tension
high or low blood pressure
