Heatstroke Flashcards
Which dogs are most predisposed to heat stroke?
Obese and brachycephalics
What is the primary heat dissipation method for dogs?
Panting
What does heat stroke lead to?
DIC, SIRS, organ dysfunction, cardiovascular collapse
When does heat stroke occur?
When body’s ability to dissipate heat is exceeded by the heat load
What results from hyperthermia?
Protein denaturation, apoptosis, activation of heat shock proteins
What is the heat critical temperature of dogs?
106*F
What are clinical signs of heat stroke?
Panting, staggering, collapse, altered mentation
Does a heat stroke patient always present with hyperthermia?
No, depends on timeline
How do you cool a hyperthermic animal?
Soak fur w/tepid water and fanning
At what temperature should you stop cooling methods and why?
103*F to avoid peripheral vasoconstriction
What are the ABCs of emergency treatment?
Airway, breathing, circulation
What IVFT should be given to a heat stroke patient?
1-2 large bore catheters for rapid infusion of crystalloids (or colloids)
How do you treat acute renal failure assoc. w/heat stroke?
Mannitol, furosemide
In cases of rhabdomyolysis, what urine pH might prevent myoglobin precipitation in kidneys?
pH=8 (alkalinization)
What GI protectants can you use in heat stroke patients?
Famotidine and sucralfate
