wounds and fracture managment Flashcards
where is the stage were veterinarians can intervene
debridement! macrophages are naturally in this stage
what are the three stages of skin healing
inflammation
proliferation
maturation and remodeling
what are the cells involved in the inflammation stage
neutrophils and macrophages
what cell is incharge of the proliferation stage
fibroblasts lay down matrix and collagen
why is proud flesh bad
epithelization cant occur
when does the maturation and remodelling phase occur
around 14 days
what is the difference between clean contaminated vs contaminated
clean contaminated- enter a luminal organ and no spillage
contaminated- fresh trauma or spillage from a luminal organ
you find a wound. what do you do? (steps)
wear latex gloves, clip the hair, clean the wound, explore the wound (sterile if near joints), lavage, debride
proper debridement is done how
with sharp excision of the entire wound.
why is dead space bad
increases risk of infection and prevents apposition of tissue = healing
what is the difference between delayed primary and secondary closure
delayed primary is done after days of lavage BEFORE granulation tissue
secondary is closed AFTER granulation tissue
sheep with discolored wool, ADR, wool falling out
fly strike. myiasis
treatment for fly strike
clip all fiber around area, catron to kill the maggots, clean, systemic antibiotics, pain meds catron daily until healed
can you use triple antibiotic on food animals
yes but they are not approved in systemic food animal so keep them from licking
the majority of food animal wounds are
iatrogenic
what is the advantage of surgical dehorning over disbudding
it has shorter healing times and there is no open wound
when is the age range for disbudding calves and goats
calves: less than 4 weeks
goats: less than 2 weeks
disbudding
local block, hold for <5 seconds
ALUSPRAY
what is something to remember about fracture healing in a ruminant
great bone healing potential. get bones in the same zip code and they will heal.
two toes split the load so its better than horse healing
what three things decrease prognosis for a fracture
sepsis, nerve damage, and vascular trauma
what type of fractures lead to a poor prognosis
proximal fractures in adults, open fractures, and articular fractures
you want to fix a fracture with an internal fixation plate. what do you need to remember
can NEVER go to slaughter
casting a bovine. what are main things to take away
change bandage often in growing animals, more layers if adults, okay to encase the hoof
