Results:Of the 776 snakebites,665(86%) were unidentified and non-envenomed.Humpnosed viper and Russell’s viper accounted for 55(7%) and 40(5%) bites respectively,of them, incriminated snakes were found in 36(65%) and 19(48%) cases.The cobra bites-5,krait bites-0. The median ages:Russell’s viper bites-41(range 16-66),hump-nosed viper bites-42(range 15- 75).The gender incidence,time of bite(】58%daytime) were similar.In hump-nosed viper bite; upper limb involved in 13(36%),happened at home garden in 22(61%),none in paddy fields.In Russell’s viper bite;6(33%) occurred in paddy fields.Dry bites were similar at 5%.In humpnosed viper bite:local effects 94%,coagulopathy 3%,acute renal failure 3%and one patient died.In Russell’s viper bite;local effects 84%,coagulopathy 53%,neurotoxicity 21%.Abdominal pain occurred only in Russell’s viper bites 10(53%).Conclusions:Overwhelming numbers of unidentified,non-envenomed snakebites are common in the central hills.Some distinctive differences were observed between Russell’s viper and hump-nosed viper bites.展开更多
