Case #1Emergency / Burns / Critical care

📋 Case data

High-voltage / abnormal ECG / myoglobinuriaHigh-voltage / abnormal ECG / arrhythmia / myoglobinuria / significant burns

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

Step 1 / 1 · High-voltage / abnormal ECG / myoglobinuria

High-voltage / abnormal ECG / arrhythmia / myoglobinuria?

💡 Current through tissue → arrhythmia (VF/VT/asystole), neurological (loss of consciousness/apnea/seizure), tetanic muscle contraction causing fractures/dislocations, deep tissue necrosis (often worse than the skin appearance), vascular thrombosis → edema → compartment syndrome, rhabdomyolysis → myoglobinuria → AKI; high-voltage (≥1000 V) is severe, lightning is usually superficial. Assess: ECG in everyone; check CK/urine myoglobin/renal function/troponin; check for compartment syndrome/concomitant trauma.
