Chunk One Flashcards
WH: inflammatory phase:
initial stage of wound healing that includes:
- clot formation
- blood vessel dilation allowing neutrophils and monocytes to initiate debridement and attack bacteria
- changes in skin color, temperature, pan, swelling and function
WH: proliferation phase:
second stage of wound healing that begins by day three after injury:
- wound revasculariation
- scab formation
- wound re-epithialization (new skin layer)
- fibroblasts initiating contraction
- erythema and beginning of scar formation
WH: Maturation phase:
final phase of wound healing that may continue for months or years that includes:
- collagen remodeling
- scar softens while its tensile strength increases
erythema lessons
debridement
a procedure performed to facilitate wound helaing and involves removal of damaged or nonviable tissue
types of debridement include:
surgical
mechanical chemical
autolytic
surgical debridement
a type of debridemet that involves surgically removing damaged or nonviable tissue with a sharp instrument
mechanical debridement
a type of debridemtnt that involves actively removing damaged or nonviable tissue
types of mechanical debridement include:
hydrotherapy
wet-to-dry dressings
- wound irrigation followed by suction
chemical debridement
type of debridement that uses fast acting enzymes to slough nonviable tissue form a wound
autolytic debridement
type of debridement that uses the body’s own enzymes to breakdown nonviable tissue
alginate dressing
primary wound care dressing that can absorb large quantities of exudate
transparent film dressing
semi-occlusive wound care dressing that can be used as a primary or secondary dressing and act as a waterproof barrier
hydrogel sheet dressing
wound care dressing that hydrates the wound and promotes autoytic debridement
scar management
technique best used six to 12 weeks after wound closure to minimize the risk of adhesions, contracture, hypertrophy or hypersensitivity
scare management interventiosn include:
mobilization orthoses ie applying submaximal stretch
massage: graded bivration , manual
compression ie: gloves tublar gauze
densitization: graded touching, textures
ROM : active and passive
thermal modalities : ultrasound moist heat
conduction
transfer of energy between two connected surfaces of contrasting temperatures
examples of conduction include:
paraffin wax
cryotherapy
hot pack
convection
transfer of energy from a circulating source in contact with a body part:
ie: fluidotherapy
whirlpool
evaporation
physiological response resulting from the topical applicaitn of a vapocoolant
ie:
cold spray
cooling cream
electrotherapeutic physical agent modalities
PAM that require esential knowledge of electrical principles electrode selctiona and placement indications and contraindications,
