Cardiac arrest and atrial fibrillation in a patient after hump-nosed pit viper (Hypnale hypnale) bite

A 42-year-old previously healthy male patient died 16 days after a proven hump-nosed pit viper (Hypnale hypnale) envenoming due to multi-organ failure. On admission he had cardiac arrest that recovered from cardiopulmonary resuscitation then developed atrial fibrillation which was reverted to normal rhythm by application of synchronized electrical cardioversion. He also had persistent coagulopathy and thrombotic microangiopathy comprising the triad of microangiopathic haemolysis, acute kidney injury and thrombocytopenia. This is the second reported case with cardiac complications following hump-nosed pit viper bites in Sri Lanka.

Ischemic brain infarcts and intracranial haemorrhages following Russell's viper (Daboia russelii) bite in Sri Lanka

Snakebite is an important medical problem in Sri Lanka. Of the deadly venomous snakes, Russell's viper (Daboia russelii) is widely distributed and responsible for most of the fatalities of snakebite in the country. It is not uncommon to see atypical manifestations in Russell's viper bite. We report the events of intracranial haemorrhages and multiple ischemic brain infarcts following Russell's viper (Daboia russelii) bite of a previously healthy 43-years-old male who succumbed to envenoming.
