Data is taken from this pathway's reviewed node text. Work through the pathway step by step.

Step 1 / 1 · Is antivenom needed?

After field management, is there local progression or systemic envenomation (antivenom needed)?

💡 Venoms are cytotoxic/hematotoxic (vipers/pit vipers — local necrosis, coagulopathy [VICC], thrombocytopenia, AKI, shock) or neurotoxic (cobras/kraits/sea snakes — mild local, progressive paralysis, respiratory failure). Field care: stay calm, immobilize the limb at heart level, remove rings/constrictors, transport quickly (antivenom timing is the key prognostic factor). Avoid arterial tourniquets, incision, suction, ice, NSAIDs. Pressure immobilization bandage only for neurotoxic snakes, not cytotoxic snakes (worsens necrosis).
