Abstract

 Background: Effective management strategies for snake envenomation are critical for reducing the morbidity and mortality as treatment gaps, delays, and reliance on traditional healers frequently exacerbate outcomes. This study provides insights into the clinical presentation, management, and outcomes of snakebite envenomation in Bangladesh admitted at an ICU, highlighting key risk factors for mortality and potential interventions.
Methods: This retrospective observational study reviewed data from 14 patients admitted to the intensive care unit (ICU) at Dhaka Medical College Hospital, Bangladesh between January 2023 and July 2024. Variables including demographic details, snakebite characteristics, baseline clinical parameters and patient outcomes were assessed.
Results: The study found snakebite envenomation predominantly affecting  males (92.8%) and urban residents (78.5%). Russell’s viper was responsible for 57.15% of bites followed by cobras and kraits. 42.85% victims consulted traditional healers initially. Cellulitis and gangrene were noted in   57.14% and   7.14% respectively. Neurotoxic effects (50%) included ptosis and respiratory paralysis. Acute kidney injury and ventilator associated pneumonia occurred in 57.14% and 42.85% of cases respectively. Treatment involved polyvalent antivenom, blood transfusions (78.5%), mechanical ventilation (64.29%), and hemodialysis (50%). In-hospital mortality was 35.71%, with an average ICU stay of 4.72 days. Hemodialysis significantly reduced the odds of mortality.
Conclusion: Acute kidney injury and ventilator-associated pneumonia are critical complications driving mortality risk.  Timely hemodialysis is a vital life-saving intervention in severe envenomation cases.  Enhanced public awareness, rapid referral systems and accessible critical care facilities are very much important to reduce snakebite-associated mortality in Bangladesh.
