Early coverage of upper extremity electrical injury wounds

Early Application of Microsurgical Flaps in the Electric Burns of Extremities: A Two Institutional Case Series

Some groups have avoided early microsurgical flaps in electrical burns under the pretext of injury to the microvasculature, which could increase vascular thrombosis. However, this option frequently results in amputation of the extremity. This study aims to evaluate the early application of microsurgical flaps for the treatment of electrical burns of extremities. A case series was retrospectively evaluated including patients with electrical trauma in extremities undergoing early microsurgical reconstruction. Data were obtained from medical charts, including age, trauma location, flap type and microvascular anastomosis, the need for other procedures, postoperative complications, the length of hospital stay after the flap surgery, and patient outcomes. Five microsurgical flaps were performed in less than 30 days to trauma, one anterolateral thigh flap to cover skin failure in upper limb, and four radial forearm flaps to cover failure in feet. The patient ages had a mean of 25.8 years (from 12 to 42 years). The microsurgical procedure occurred from 21 to 27 days after the burn, with a mean of 24.2 days. Hospital discharge had a mean of 26.6 days (from 19 to 35 days after the surgery). Only one patient required reintervention for re-anastomosis. All patients had a good flap viability, avoiding amputation of the affected extremity and with a proper preservation of function. The early application of microsurgical flaps for patients with electrical burns of extremities may provide adequate, sturdy, and stable skin coverage, contributing to the treatment of noble structures exposed and avoiding amputation of the extremities.
