Animal Emergencies Flashcards
tx of marine toxicity
detoxify venom (rinse with saline, freshwater may activate)
pain and symptom relief
activation and removal of attached nematocysts
infection likely in marine environments
aeromonas
vibrio
pseudomonas
erysipelothrix
3 major groups of venomous snakes
viperidae (vipers)
elapidae (coral snakes)
hydrophiinae (sea snakes)
North American venomous snake bites involve
pit vibers (crotalinae viperidae) coral snakes and cobra snakes
first aid for all snake bite victims
- retreat
- limited movement to decrease venom absorption
- ensure prompt transport to ER
- contstriction bands
- IV access in another limb, O2
crotaline envenomation patho
systemic vascular damage, hemolysis, fibrinolysis, neuromuscular dysfunction
altered permeability = loss of plasma and blood
consumption of fibrinogen and platelets
some species NM dysfunction in crotaline invocation
cranial nerve weakness
respiratory failure
altered sensorium
clinical features of crotaline envenomation
presence of one or more fangs, localized pain, progressive edema from bite site
nausea, vomiting, weakness, oral numbness/tingling, dizziness, muscle fasciculation
progressive ecchymosis (leakage of blood), within minutes or hours
systemic effects of crotaline envenomation
TACHYPNEA, TACHYCARDIA, HOTN, ALTERED CONCIOUSNESS
crotaline envenomation tx
constriction irrigate wounds obtain labs analgesia update tetanus ANTIVENIN
DO NOT suck and incise
who does not get antivenin crotaline envenomation
pts without progression of signs and symptoms bc likely a dry bite
antivenin crotaline envenomation
given to all progressive crotalid bites
platelets <100,000 are considered threshold
antivenin crotaline envenomation
CroFab
neutralizes toxin when given early
do not give to coral snakes
immediate crotaline envenomation complications
local necrosis shock coagulopahty rhabdo compartment syndrome neurotoxicity
delayed crotaline envenomation complications
renal failure compartment syndrome antivenin rebound serum sickness delayed thrombocytopenia
