High-voltage electrical injury complicated by compartment syndrome and acute kidney injury with successful limb salvage: A case report and review of the literature

INTRODUCTION: Although an uncommon form of admission to a burns centre, the deep, penetrating nature of noxious currents mean that electrical burns have the most catastrophic consequences of all burn injuries. Understanding the physics of electricity is crucial to explaining the mechanisms of tissue damage and organ failure in electrical injuries which necessitate special management above and beyond that of regular thermal burns. PRESENTATION OF CASE: We present a young man who suffered significant occupation-related electrical burns that was complicated by compartment syndrome, rhabdomyolysis and acute kidney injury. He required multiple surgeries (including fasciotomy as well as soft tissue reconstruction), critical care and lengthy rehabilitation. DISCUSSION: Rhabdomyolysis is common sequela of electrical burns and may result in severe and permanent metabolic and renal impairment. High cut-off dialysis membranes have shown great promise in myoglobin removal but further studies are required to determine whether this improves clinical outcomes. Debridement and decompression are the cornerstones of initial surgical intervention and are crucial to minimising infectious complications and preserving vital structures. Free tissue transfer has become increasingly popular, but the ideal timing of microsurgery is still uncertain. Nonetheless, pedicled flaps remain widely used and still have an important role in reconstruction of electrical burns. CONCLUSION: Patients with electrical injuries have several unique acute manifestations that differ from other burns. Prognosticating outcomes is difficult, as the full scale of damage is seldom immediately evident. Multiple organ systems are often affected, which makes the treatment of such patients exceptionally challenging, multi-disciplinary and resource-intensive.
