Clinical Management of North American Snake and Marine Envenomations

Envenomations are the 23rd most common reason for calls to US poison control centers, with over 35,000 incidents reported annually. Snake bites account for over 20% of those calls, while marine envenomations are likely underreported at 3% to 4%.¹ While these types of envenomations may not be encountered on a daily basis for many physicians, the different types of envenomations warrant unique management strategies based on the offending creature and symptom presentation. This text serves as a review of the epidemiology, clinical presentations, and management of endemic North American species of snakes and marine vertebrate and invertebrate envenomations.
