American rattlesnake (Crotalus durissus terrificus) bite accidents in dogs in Argentina
The symptomatology and treatment of two dogs bitten by Crotalus durissus terrificus are described. Neurological signs were present few minutes after the accident with local anesthesia and ataxia of the affected limb and neurotoxic fascia. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine kinase (CK), lactate dehydrogenase (LDH) and calcium were evaluated in an attempt to investigate muscle damage. Renal failure was not observed but some alterations were detected in urine. Urine density was low and the urinary sediment contained granular clumps and small round cells. Muscle samples were obtained from both legs for histopathological study, showing edema and isolated necrotic fibers. Both dogs received treatment within four hours after the accident by intravenous route. The antivenom was administered diluted in 250ml of Ringer solution in a dose enough to inactivate more than 8mg of venom. Dexamethasone was applied previously to the antivenom. Clinical evolution was good and both patients were in good health condition on the second day after the accident.
