What is Sao Paulo Lancehead Snake Bite? (Definition/Background Information)

  • The Sao Paulo lancehead (Bothrops itapetiningae) is a venomous snake that ranges in size from a foot to 1.5 feet or more in length. The snake belongs to the subspecies of pit vipers, family Viperidae. Pit vipers are termed so, due to the presence of certain heat-sensing organs located in a recess/notch between their eyes and nostrils
  • This reptile is found at elevations of about 4,900 feet (1,500 m) in the tropical savanna ecoregion (Cerrado) and cultivated lands of Brazil and Paraguay in the South American continent. It is a nocturnal snake that hunts at night, preying mainly on small mammals, birds, lizards, and frogs
  • The Sao Paulo lancehead snake has a medium to stout body. The head of the snake is broad and shaped like a lance (spear) and distinct from its neck. The snake color is normally pale or dark brown with red, pink, or orange shades, and presenting dark and narrow, oval blotches with white-edges
  • Sao Paulo Lancehead Snake Bites involving humans are very uncommon. Even though infrequent, a bite from a fully-grown snake has the potential to result in severe envenomation (venom injection) with significant symptoms, in the absence of adequate treatment. The snake venom is a potent mix of hemotoxins and can cause hypovolemic shock and renal failure
  • In general, the signs and symptoms of Sao Paulo Lancehead Snake Bite may include moderate to severe pain at the bite site and local swelling with bruising, blistering, and tissue necrosis. In case of systemic symptoms, the bite can result in headache, nausea and vomiting, abdominal pain, diarrhea, seizures, and collapse
  • Early administration of suitable antivenom (or antivenin) is the mainstay of treatment. Apart from this, symptomatic treatment is necessary, which may include the use of pain medication, wound care, blood transfusion, and breathing support, if needed. The prognosis of Sao Paulo Lancehead Snake Bite with prompt and effective therapy is usually good; fatalities are generally not reported but can take place occasionally
