Could this be snakebite?

Australian snakes are among the most venomous in the world. Although usually obvious, the occurrence of snakebite is occasionally unrecognised by the patient and/or physician, resulting in delayed or inadequate treatment, or even in death.

This article describes the historical, clinical and pathologic features associated with envenomation by various Australian venomous snakes, and discusses the investigation and management (including first aid) of suspected snakebite.

A high index of suspicion should be maintained, particularly in rural areas and in patients unable to give a history. Investigations including creatine kinase, clotting profile and venom detection kit should be performed in cases of suspected snakebite. The choice of appropriate antivenom and its indications are discussed.
