Hump-nosed pit viper (<i>Hypnale hypnale</i>) envenoming causes mild coagulopathy with incomplete clotting factor consumption

Abstract

Hump-nosed pit viper bites result in a mild coagulopathy which is usually not detected by a WBCT20. It is characterised by mild elevation of INR, low fibrinogen and Factors V and VIII which may be consistent with the venom containing a thrombin-like enzyme.
