Pre-Hospital and Hospital Management Practices and Circumstances behind Venomous Snakebite in Northwestern Part of Bangladesh

Background: Snakebite is the most important cause of envenomation in South Asia particularly in Bangladesh, though there is lack of data from the rural part of the country. About 82 species of snakes (28 venomous) exist in Bangladesh. In this study, demographic characteristics of the victim, circumstances behind the bite along with pre-hospital and hospital managements and outcomes were evaluated. Methods: It was a cross-sectional study during January 2010 to June 2012 at Rangpur Medical College Hospital. Only venomous snakebite cases were included and diagnosis was made on clinical syndrome. Descriptive statistics were presented using percentage and proportion. Results: Out of 28 patients (mean age: 31.7 years), 20 (71.4%) were males with a significant male-female ratio (2.5:1). Majority were farmers (46.4%) and most (50%) of the bites happened during household activities. Lag period between bite and hospitalization was ≤5 hours in 50% patients; 6 to 10 hours in 39.2% and >10 hours in 10.7% cases. 82.1% patients received ligature as pre-hospital first aid. Total 21 patients received anti-snake venom (ASV) in different dose regimens. 15 (53.5%) patients recovered while 13 (46.4%) died. Among 13 patients who died, 53.8% died within 2 hours, 15.3% within 3-24 hours and 30.7% after 24 hours post-bite. Conclusion: Snakebite has a significant impact on human health and economy through treatment-related expenditures and loss of productivity. Policy makers of Bangladesh should prioritize the issue to reduce future mortality and morbidity. Keywords: Poisoning, Snakebite, Bangladesh, Envenomation, Management
