Indian common krait envenomation presenting as coma and hypertension: A case report and literature review

Abstract

Neuroparalytic snake bite is a common emergency situation encountered in India. Common krait (Bungarus caeruleus) and cobra (Naja naja) are important snakes causing neuroparalysis in North India. Despite severe neuroparalysis, patients who receive antivenin and ventilator support in time recover completely. Autonomic disturbances resulting in resting tachycardia, labile hypertension and sweating have been described in common krait envenomation. We present a case of common krait (B. caeruleus) envenomation presenting in the locked-in state and severe hypertension that remained in such a state for over 96 h before a gradual and sustained recovery.
