Step 1 / 1 · High suspicion?

High clinical suspicion of necrotizing fasciitis (red flags)?

💡 Surgical emergency with high mortality, a clinical diagnosis. Red flags: pain out of proportion to findings, rapidly spreading erythema/swelling, woody induration extending beyond the visible area, systemic toxicity, skin necrosis/bullae/hemorrhagic blisters/crepitus, no response to antibiotics at 24–48 h. LRINEC (Na/glucose/creatinine/CRP/WBC/Hb) ≤5 low, 6–7 intermediate, ≥8 high — poor sensitivity, cannot exclude, only adjunctive; do not delay surgery.
