Snakebites are common in India and the most common neurotoxic snakebites in India are due to Common krait (Bungarus caeruleus) and cobra (Naja naja). Severe envenomation may mimic brain death or a locked-in state with flaccid paralysis in a descending manner and total ophthalmoplegia. Usually, patients who receive timely antivenom and ventilator support recover completely without any sequalae. We are reporting two cases of krait bite with an unusually long period of flaccid paralysis, which required prolong ventilation. While case 1 required 10 days of mechanical ventilation followed by 5 days of non-invasive ventilation, case 2 required 11 days of mechanical ventilation followed by 5 days of non-invasive ventilation. Both the cases had delayed recovery and residual weakness at 3-month follow up. These case reports suggest that krait bite may cause prolong neuromuscular weakness in children, which has implications for both acute and chronic management. Copyright © 2021 Elsevier Ltd.
