healing Flashcards
rocess of healing
haemotasis
inflammation
proliferant
remodelling
haemotasis
break in blood vessel
form a blood clot
vasoconstriction
inflammation
vascular dilation
vascular permability
wbc in the site in infection
proliferation
new epithelium growth
fibrin clot is broken down
granulation
angiogenisis
new connective tissue is regrown
clear away dead of necrotic tissue
remoddeling
collagen fibre reallign on the line of where the stress is being applied
reabsorption of water
pagocytic activity decline
scar tissue is produced
keloid
raised and thick scar
excessive collagen
larger than initial trauma
hypertrophic
raised thickened scar
excessive collagen
scar is maintained within wound margins
widend
gaping wound
healing prologned
excess tension on wound edges
stage 1 of bone healing
reactive phase
fracture haematoma forms
swelling and inflamation occurs
stage 2 of bone healing
regenitive
callus forms
- fibrocartlidge forms in gap where break occurred
it then is transformed into spongy bone
stage 3 of bone healing
remodelling
osteoclast smooth callus
compact bone replaces spongy bone
bone healing in elderly
Greater risk of injury
* Balance deficits.
* Impaired healing
* Including complications from other conditions e.g. cardiovascular disease,
diabetes.
* vascular supply to skin.
* immune response.
* inflammation.
RICE
REST
ICE
COMPRESSION
ELEVATION
REST- protects from further injury and reduces pain
Ice
provides short-term pain relief; decreases blood flow to limit swelling
Compression
reduces swelling to decrease pain and loss of function e.g. limit swelling at a joint so joint movement may still occur
Elevation
4
elevation of a limb reduces swelling and increases venous return to the heart
ENDOGENOUS
Poor blood flow
Decreased O₂ and nutrient supply
Decreased waste removal
Poor nutrient delivery
New tissue has increased metabolic demand
Requires increased glucose, proteins, vitamins, minerals
