EDGE24 Module 12 : Envenomation: Snake and Spider Bite

Latest Course Update: January 2024

In this module we will explore the assessment and management of patients presenting with red back spider bite and snake bite.

Although suspected snakebite is a relatively common ED presentation during the spring and summer months, it is only rarely is associated with the clinical findings of severe envenomation. Management is time critical and begins with appropriate first aid of the snakebite followed by clinical and laboratory assessment of the patient for features indicative of envenomation.

While Red Back Spider bite is the most common cause of significant envenomation presenting to emergency care, in contrast to snake bite the venom can be slow acting and does not cause life threatening envenomation. Considerable controversy exists with respect to the use of antivenom in red back spider bite with an evolving change in clinical practice.
