One of the drawbacks of its bites is that it potentially causes acute renal failure. The venom destroys the kidneys, with kidney failure often claiming the lives of people who survive the initial bite, and hemorrhaging occurs throughout the body including in the pituitary gland. Full recovery from bites from a Russel's Viper is rare, as … The Russell’s Pit Viper is far more dangerous than most poisonous snakes because it harms you even if you survive the initial bite. A study in The Lancet showed that out of a sample of people bitten by D. russelii who survived, 29% of them suffered severe damage to their pituitary glands, which … This snake accounts for the majority of snakebites in southeast Asia. The Russel's Viper or Daboia russelii is responsible for a high morbidity (symptoms indicating Russel's viper bite) and fatalities. In the dRVVT assay, low, rate-limiting concentrations of both Russell's viper venom and phospholipid are used to give a standard clotting time of 30 to 40 seconds. Death from septicaemia or kidney, respiratory, or cardiac failure may occur 1 to 14 days after the bite or even later. However, it is essentially a nocturnal snake and numerous bites occur at dusk and in the early hours of the night, usually on foot paths, roads and home gardens (Kularatne, 2003). (7) This makes the test sensitive to the presence of lupus anticoagulants, because these antibodies interfere with the clot-promoting role of phospholipid in vitro, and their presence results in a prolonged clotting time. This is a dangerous snake, as it can strike with great force and speed, and deliver greater than the lethal dose in humans. Most Russell’s viper bites (63%) occur in the day time, between 6 am and 6 pm (Silva et al, 2016b). Russell's Viper (Vipera russelli pulchella & Vipera russelli siamensis) This person has received a bite and probable envenomation from a Vipera russelli.
