Extracorporeal Hemoperfusion as an Adjunctive Therapy in Neurotoxic Snakebite Envenomation: A Case Report

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Snakebite envenomation is a medical emergency with potentially fatal systemic complications. We report a case of a 32-year-old male patient who presented to the Emergency Department with a complaint of a snakebite on his right ear. On arrival, he didn’t have signs of bleeding, fever, or swelling. Two hours after admission, the patient developed cardiac arrest and required mechanical ventilation. Although resuscitation was successful, the patient’s condition deteriorated, with progressive neurological and motor deficits, despite unremarkable findings on head CT scans and chest X-rays. Given progressive neurological and motoric deficits, hemoperfusion was initiated six hours post-envenomation as an adjunctive therapy. The procedure lasted six hours using a standard hemoperfusion cartridge. The patient demonstrated significant neurological recovery within 22 hours post-procedure, and he was successfully extubated on day 4. This case highlights the potential role of hemoperfusion as an adjuvant treatment in managing venomous snakebite envenomation, especially in places with limited species-specific antivenom availability. Early recognition of systemic complications and timely initiation of hemoperfusion may improve neurological outcomes in critically envenomed patients.
