Unknown Snake: Signs and Symptoms
| 1. Neurotoxicity. There appears to be little or no neurotoxicity or else neurological involvement is not a major clinical feature of the envenomation. Return to this step. |
| 2. Rhabdomyolysis. There is no evidence that rhabdomyolysis is a feature of the envenomation. Myalgia or myoglobinuria are not present. Return to this step. |
| 3. Coagulopathy. The INR is extended, and the fibrinogen level is significantly below the reference range, indicating procoagulant activity. Return to this step. |
Likely species:
Eastern Brown Snake. Eastern brown snake bites are very common. The prominent feature of eastern brown snake envenomation is coagulopathy caused by procoagulant venom components. Infrequently, the neurotoxic effects of the venom are of clinical significance, although not usually. Myolytic activity is unknown.
Gwardar. The gwardar, or western brown snake, causes a clinical picture similar to the eastern brown snake. The amount of of venom delivered in a typical bite is thought to considerably exceed that of eastern brown snakes.
Dugite. Envenomation by dugites causes a clinical picture similar to the eastern brown snake.
