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

Methods: To retrospectively analyze the 841 cases of serpentine bites in our hospital from January 2006 to July 2017;127 cases of patients with rhabdomyolysis syndrome were screened out, and their clinical manifestations, laboratory results, related treatment and prognosis were analyzed. Results: 127 cases patients were rhabdomyolysis out of 841 cases, 28 cases patients developed acute renal failure;treatment measures included local wound treatment, application of tetanus antitoxin, anti-snake venom serum, anti-infection, fluid “hydration” and diuretic, alkaline urine and hybrid renal replacement therapy. 112 cases were cured, improved conditions in 9 cases, 3 cases of death, 3 cases uncured. The improvement rate of is 95.26% after treatment. Conclusion: The rhabdomyolysis had a high incidence in snake bite patients, severe cases often developed acute renal failure. Serum myopsin and related biochemical blood tests could be used to diagnose rhabdomyolysis quickly. Combined treatment methods are the main measure to increase the cured rate and decrease the death rate.展开更多

It can lead to a poor outcome in both the mother and the fetus. We describe our approach to envenomation in pregnancy based on the currently available evidence. Case: We reported two case of snakebite in the third trimester of pregnancy having caused placental abruption with expelling a fresh still born baby and a live baby. In both cases, consumption coagulopathy occurred. managed by polyvalent anti-snake and blood transfusion. Their investigations became normal and they were discharged of hospitalization. Conclusion: Snakebite envenomation in pregnant is a maternal and fetal emergency. Treatment must be quick and well adapted.展开更多

Tropical and subtropical countries are most effected, Bangladesh being one of them. There is scarcity of countries’ epidemiological situation in relation to snakebite poisoning. This study has looked at the epidemiological status of snakebite poisoning from national representative survey findings. Methods: A nationwide cross-sectional survey was conducted in 12 randomly selected districts of Bangladesh in 2003. A total of 171,366 households were surveyed and information was collected from 819,429 populations by face to face interview. Multi-stage cluster sampling methods were used in this survey and covered urban, rural and slum populations. Results: Annually an estimated 15,372 (10.98/100,000) individuals were bitten by snakes and of them 1709 (1.22/100,000) died every year. Males were found to be most vulnerable with a risk of 1.51 times higher than female. Rural populations were also 10.54 times higher at risk than the populations living in the urban areas. Among the victims 94% were from the poor socio economic conditions. Around 43.9% of the incidences occurred during evening to midnight. Home was found the most common area for snake bite (33.6%), and the Leg was found to be the most common site for biting (63.1%). A total of 96.6% victims sought treatment, of them 61% sought immediate treatment from traditional healing methods. Conclusions: Present incidence of snakebite in Bangladesh has clearly shown that there is emerging public health needs for intervention that can reduce the mortality and burden of the disease in the country.展开更多

None of the patients that had coagulopathy developed renal failure.Contamination of the sample by mildly venomous species of Hypnale may have contributed to the low incidence of systemic complications.Conclusions:It is likely that early hydration with normal saline or FFP can prevent acute renal failure.FFP showed a tendency for early correction of coagulopathy.Role of FFP in hump nosed viper envenomation is worth studying in randomized double blind controlled clinical trials.展开更多
