Abstract

Bleeding diathesis is a cardinal feature of viperine bite, which has been thought to last not more than 24 hours. There is scarcity of literature about prolonged bleeding disorder in snake envenomation. Various explanations suggested in the literature include-temporary decrease in antivenin levels, rapid elimination of antivenin from circulation or continuous release of unneutralised venom from the envenomated site. Two children with prolonged coagulopathy lasting for more than a week, correction of which required more than 300 ml of antisnake venom are reported here.

[Aggravation of snake bite in France and their treatment].

VIPERS AT THE ORIGIN OF ENVENOMING: Out of the 4 species of vipers found in France, only two can be responsible for severe envenoming: the aspic viper (Vipera aspis) and the addetr (Vipera berus). CLINICAL GRADING: Since 1992, a grading table published by the Institut Pasteur in Paris helps to assess the severity of the clinical and biological picture. A grade 2 (extensive oedema +/- accompanied by moderate general signs) or notably a grade 3 (giant oedema + severe general signs + biological signs) implies the administration of an antivenom. ANTIVENOM VIPERFAV: Available on the market since 2000, is administered in intravenous infusion, the only route effective. Tolerance to the treatment is good and clinical improvement is rapid after administration of 1 to 4 infusions of antivenom. When confronted with life-threatening envenoming, there is no strong argument to justify the non-use of an antivenom. VIPERINE ENVENOMING: Among the grass snakes, the viperine snake of Montpellier is the only species that is actually venomous. The fangs are posterior in the buccal cavity of the snake, which does not usually permit it to inject its venom in humans. In exceptional circumstances (finger placed in the throat), envenoming has been observed with, in this case, essentially neurological clinical signs: involvement of the cranial nerves, drowsiness. There is no specific treatment for these extremely rare accidents.

Snake bite in Australia: first aid and envenomation management.

Australia is inhabited by a large variety of snakes, including some of the most poisonous in the world. Sightings are regular, and the incidence of snake bite is estimated to be several thousand a year. A bite does not necessarily result in envenomation occurring, however there are at least 300 snakebites a year requiring treatment of envenomation, with between 1 and 4 fatalities every year. The incidence of fatalities from snake bite has increased over recent years. The explanation for this is unclear, but possible reasons include the urban sprawl, and a delay in application of appropriate first aid and definitive treatment for envenomation. Emergency nurses in particular should be aware of the first aid techniques appropriate for Australian snake bite, as well as the recognition and management of envenomation. This article will outline the steps required and rationale for applying first aid techniques considered to be effective in retarding spread and circulation of snake venom. It will also discuss the manifestations that indicate systemic envenomation, and management considered to be responsible for reducing the incidence of death from snake envenomation in Australia.
