IM21.1-3 | Snake Bite Foundations and Field Care — Summary & Reflection

KEY TAKEAWAYS

The big four medically significant Indian snakes: Russell's viper (stout, dark blotches with pale borders, haematotoxic — VICC + AKI), saw-scaled viper (small, rough keeled scales, rasping sound, haematotoxic — coagulopathy + thrombocytopenia), Indian cobra (hood, spectacle mark, post-synaptic neurotoxic + cytotoxic — ptosis→paralysis + local necrosis), common krait (shiny, white crossbands, pre-synaptic neurotoxic — painless nocturnal bite, descending paralysis difficult to reverse).

Field first aid — DO: immobilise the limb, reassure and keep still, remove constricting items, apply PIB only for confirmed neurotoxic elapid bite, transfer immediately.

Field first aid — DO NOT: apply tourniquet, perform incision-suction, give herbal medicines, apply electric shock.

Hospital stabilisation: ABCDE approach — airway and respiratory monitoring are priority for neurotoxic bites (ptosis = imminent danger); two IV lines, IV fluids for shock; 20WBCT + coagulation studies + renal function; 24-hour observation minimum. Gradually release any existing tourniquet over 5–10 min with antivenom ready.

REFLECT

Reflect on the opening scenario: the first responders applied a tourniquet and performed incisions — two interventions actively contraindicated by the evidence. These interventions are culturally embedded and widely taught by word of mouth in rural communities. As a physician posted to a primary health centre, you will be the person who can change this practice — not only by managing the acute case correctly, but by educating community health workers, ASHAs, and the patient's family on correct first aid. How would you explain, in language a village panchayat member can understand, why the tourniquet should NOT be used? What single message about snakebite first aid would you leave behind after a health camp in a high-risk agricultural village?
