Young man bitten by a snake reported 24?h after traditional first aid at the village. He had no features of systemic envenomation. Local examination of the right lower limb revealed a clear delineation mark secondary to tight bands. On washing the limb, fang marks (broad red arrow in figure) with multiple local incisions/pricks/punctures below the knee in the bitten limb and blisters were noticed.
He was given bolus dose of Indian polyvalent antivenin. Patient developed features of septicaemia, muscle spasms, dysphagia after 7?days of the bite and later respiratory weakness requiring a prolonged ventilation. What to do now?
