Abstract

Background: Snake bite is one of the most neglected diseases in South East Asian region. Common Krait (CK) (Bungarus caeruleus) is the deadliest snake found in the dry zones of India. With the polyvalent anti-venom serum (AVS) remaining the cornerstone of treatment of neurotoxic snake envenomation, there is no universally accepted treatment for CK envenomation-associated neuroparalysis, except supportive measures.

Aims and Objectives: Our study was conducted to describe the epidemiology, define clinical features, study outcome, and apparent efficacy of calcium gluconate in preventing or reversing neuromuscular paralysis with respiratory failure in CK bite patients.

Materials and Methods: This study is a prospective observational study done on 52 CK bite patients. Patients were enrolled according to inclusion and exclusion criteria and were treated with AVS and calcium gluconate infusion according to National Standard Guideline, 2016. Patients developing severe respiratory muscle paralysis were offered mechanical ventilation.

Results: Patients developed ptosis and dysphagia, pain abdomen, cyanosis, paralysis of jaw and tongue, perioral numbness, altered sensorium, dysphonia, ophthalmoplegia, and paradoxical breathing. 21.15% of patients developed respiratory failure and needed ventilator support with average critical care unit stay of 3 days and average stay on a ventilator of 2 days. 3 patients expired (case fatality rate 5.77%). The average hospital stay was 3.33 days.

Conclusion: Our study shows that early intervention in patients of CK bite with neurotoxic envenomation, with calcium gluconate infusion, leads to less mortality and morbidity compared to other relevant studies. Further large-scale studies are required for better understanding and implementation.
