Naja species Bite Injury- Pathophysiology of Envenomation and Multidisciplinary Approach in Management

Abstract

Cobra bite envenomation is one of the commonest causes of snake related injuries in Malaysia. Local tissue injury following a cobra bite is a complex sequalae of envenomation that is attributed to various peptides and enzymes including cytotoxin, metalloproteases, phospholipase A2 and hyaluronidase. This case involves a young construction worker who was bitten by an unidentified snake on the dorsum of his left foot. He presented with typical features of local and systemic envenomation of a Naja species. Remote Envenomation Consultancy Services was consulted and the appropriate antivenom was administered. The patient underwent wound debridement and subsequent skin grafting. Follow up at outpatient clinic showed good skin graft uptake and recovery. Managing a significant Naja species bite envenomation can be a lengthy process requiring expertise from various subspecialties. Timely and seamless multidisciplinary approach in managing a Naja species envenomation ensures a favorable outcome with minimal complication.
