High or low- a trial of low dose anti snake venom in the treatment of poisonous snakebites.

To demonstrate that use of lower doses of anti-snake venom is as effective as high doses and is associated with less complications and lower mortality especially in the wake of rising cost of medical treatment, the people most affected by snakebites being the poor farmers.
A prospective descriptive study consisting of 54 snakebite patients fulfilling the inclusion criteria who were admitted to Bangalore Baptist Hospital, Bengaluru, between November 2006 and November 2008 and were treated with a low dose ASV regime. The patients were initially given 2 vials of ASV followed later with 1 vial at a time according to clotting time. Any other supportive measures were undertaken as necessary.
In this study the average dose of ASV required was only 6.70 +/- 3.24 vials. The complications--12.9% patients had ARF, and another 12.9% patients had neuropraralysis severe enough to require ventilatory support. There were 2 deaths (mortality of 3.7%) in the study.
Low dose ASV regime in poisonous snakebites along with supportive treatment as necessary is as good as high dose regime, and has lesser adverse effects while reducing the cost of treatment too. Hence low dose regime can be used with beneficial results in poisonous snakebites.
