Wounds Flashcards
open wound - define
break in the skin surface
wounds: 2 x clasifications
open & Closed
open - 7 types
avulsion, abraisions, deegloving, incised, lacerations, shear, puncture
possible causes of: avulsions
dog fights, falls, RTA
possible causes of: abrasions
Friction, RTA
possible causes of: Degloving
RTA or animal trap
possible causes of: incised
knife/scalpel, glass, metal
possible causes of: laceration
dog fights, barbed wire, RTA
possible causes of: shear
dog fight, animal trap
possible causes of: puncute
bites, shootings, nails, thorns, teeth
appearance of: avulsions
skin is torn from your body during an accident or other injury
appearance of: abraisions
shallow scrape on the skin surface
appearance of: degloving
extensive section of skin is completely torn off the underlying tissue
appearance of: incised
clean cut through the tissues
appearance of: laceration
produced by the tearing of soft body tissue
appearance of: shear
downward pressure AND friction.
appearance of: puncture
pointed object that pierces or penetrates the skin.
Closed - 3 types
haematoma, contusion, injuries to internal organs
possible causes of: haematoma
head shaking, blunt trauma
possible causes of: contusion
blunt force trauma, blood sampling, surgery
possible causes of: internal injuries
blunt force trauma, dog fights, rta, kick injuries
appearance of: haematoma
abnormal collection of blood outside of a blood vessel
appearance of: contusion
blood vessels are damaged or broken as the result of a blow to the skin
appearance of: internal injury
Disturbance of the different regulating systems in the body
wound healing phases
inflamatory phase, proliferative phase, remodelling phase.
signs of inflammation
PRISH Pain, Redness, Irittation, Swelling, Heat
Define: Acute inflammation
immediate and rapid response to an injury
define: chronic inflammation
inflammatory response which has occured for longer than expected (weeks/months)
3 x outcomes of wound healing
resolutiom, regeneration, organisation
define: resolution
no tissue distruction, inflammatory process is mild, tissue returns to its orginal state before the injury
three examples of why chronic inflammation might occur
persistant infections, prolonged exposure to foreign body, autoimmune disease
define: regeneration
damaged tissue is replaced by proliferation of remaining cells.
when can regeneration occur
when vasculature is still intact to allow blood supply
what types of cells are unable to regenerate
cardiac cells and nuerons
define: organisation (wound outcome)
cells cannot be repaire by regeneration, tissues heals by formation of scar tissue
What is 2 problems with scar tissue
loss of function, more susceptible to recurrent damage
