Immediate radical fang mark ablation may allow treatment of japanese viper bite without antivenom

Administration of antivenom is currently the standard treatment for snake envenomation. However, it can sometimes cause anaphylactic reactions including urticaria, bronchospasm and hypotension. Furthermore, it may also provoke life-threatening complications, even though the mortality rate is less than 1 percent. In this study, we present a new treatment - immediate radical fang mark ablation - that was successfully performed on five victims of Japanese viper bites without antivenom use. In these five victims of venomous snakebites, surgical debridement was immediately performed. Two patients received a free-skin graft to resurface their wounds while three of them healed conservatively (i.e. by ointment treatment without surgery). After treatment, all patients could return to work. Immediate radical ablation is a recommended procedure that can reduce the amount of venom in tissues, which consequently decreases inflammatory reactions and reduces the necessity for antivenom.(AU)

Victimologic study of snakebite envenomation.

Snakebite is of grave concern in most parts of India. Being a tropical country with an extensive coastline, India is home to a variety of snakes both poisonous and non-poisonous. This is a retrospective research study conducted at Kasturba Hospital, Manipal, which is a tertiary care teaching hospital situated in Coastal Karnataka, South India. During a three-year period starting from 1st January 2001 to 31st December 2003, one hundred and twenty six cases of snakebites that were admitted at Kasturba Hospital, Manipal were studied. The commonest age group affected was 21-30 years with a male preponderance (66.7%). The victims were agriculturists in 54 cases. Most of the bites occurred during summer. Bites occurred when the victim was outdoors in 72.2% of the cases. Lower limb was commonly involved. Double fang mark was seen in 47.6% of the cases. Non-poisonous snakebite was seen in 38.1% of the cases. One hundred and twenty patients survived, and 6 persons died, representing a mortality of 4.8%.
