Abstract Background Local tissue damage caused by electrical burns is often deep and severe. High-voltage electrical burns are common in the head, neck and torso areas. These are mostly caused by direct contact with the power supply and are often accompanied by deep injuries of the nerve, blood vessel, muscle, tendon, and bone. We must pay great attention to the clinical treatment of these parts injured by electrical burn. Case presentation The first case involved a migrant worker who touched a 6-kV high-tension wire when welding steel; this electric shock caused burns in many places. Deep electrical burn wounds were mainly located on the left shoulder and back, characterized by widespread skin and soft tissue defect and bone necrosis. We utilized a lower trapezius myocutaneous flap to repair these wounds in the neck and back caused by deep electrical burns. The flap survived completely and the wound was effectively repaired. The function and shape of the shoulder and back after the restoration were satisfactory. The second case involved a 29-year-old who accidentally touched a high-voltage wire while working and was burned by a 30,000-V electric shock. His wounds were mainly located on the left head, neck, back and left upper limbs. We designed a 30 cm × 12 cm right trapezius myocutaneous flap which completely covered the wound surface; the electrical burn wounds on the neck and back were effectively repaired. After the electrical burn wound was repaired, the neck function returned to normal with a satisfactory shape. Conclusion The authors report two cases of patients who were burned by high voltage. We used lower trapezius myocutaneous flaps to repair their wounds, which achieved satisfactory clinical results. This study has provided a reliable surgical method for the clinical treatment of deep electrical burn wounds in the neck, shoulders and back.

Minimal Information

Hearing loss associated with high-voltage electric shock is a rare entity and minimal information is available in the current literature about this condition. To our knowledge, this article represents the first case report in the literature of improvement in sensorineural hearing loss sustained due to a high-voltage electric shock.A case report of a patient who incurred various otologic problems, including hearing loss and tinnitus, is presented. An improvement in hearing loss and tinnitus was observed in the subsequent follow up after one month. Audiological findings and possible pathophysiology of hearing loss are discussed.We recommend that further studies be done to investigate the incidence, severity and pathophysiology of hearing loss in such cases.

First Case

Introduction. We described the first case of oversensing due to electric shock in Serbia, in a 54-year-old man who had implantable cardioverter-defibrillator (ICD). Case Outline. In July 2002, the patient had acute anteroseptal myocardial infarction and ventricular fibrillation (VF) which was terminated with six defibrillation shocks of 360 J. Coronary angiography revealed 30% stenosis of circumflex artery, the left anterior descending coronary artery was recanalized and the right coronary artery was without stenosis. Left ventricular ejection fraction was 20%. In December 2003, an electrophysiology study was performed and ventricular tachycardia (VT) was induced and terminated with 200 J defibrillation shock. Single chamber ICD Medtronic Gem III VR was implanted in January 2004 and defibrillation threshold was 12 J. The patient was followed up during three years every three months and there were no VT/VF episodes and VT/VF therapies. In December 2007, the patient experienced electric shock through the fork while he was making barbecue on the electric grill. ICD recognized this event in VF zone (oversensing) and delivered defibrillation shock of 18 J. The electrogram of the episode showed ventricular sensing - intrinsic sinus rhythm with electric shock potentials which were misidentified as VF. After charge time of 3.16 seconds, ICD delivered defibrillation shock and sinus rhythm was still present. Conclusion. Oversensing of ICD has different aetiology and the most common cause is supraventricular tachyarrhythmia.

Liver Injuries

Liver injuries caused by high voltage electricity are rare and result in high mortality and morbidity. They are produced by the resistance to the passage of electrical current through the tissue, which creates heat that leads to coagulation necrosis and rupture of the cell membrane. We present a case of an electrical injury to the liver, diagnosed by ultrasound and CT in a 39-year-old man who presented with skin burns on his right hand and right hemiabdomen. Injuries occurred after the contact with 220 kV high voltage electricity.

Electrical Burns

Abstract Introduction The art of pyrography, creating designs in wood with a thermal heat source, dates back to prehistory. Risks include cutaneous burns and airway injury. Fractal woodburning is a niche method of pyrography utilizing a high-voltage electrical source to burn branched designs – Lichtenberg patterns – into the surface of wood. While this technique has grown in popularity, the associated risks are not well described. Methods We describe a patient who presented to our burn center after sustaining high-voltage electrical burns from a homemade high-voltage device constructed for fractal woodburning. We also evaluated publicly reported cases of death or injury due to this technique. Results An otherwise healthy 17-year-old male was admitted to our burn center with injuries sustained while making fractal wood art. The patient improvised a high-voltage transformer from a discarded microwave, generating 2000 volts from household current. While using this device to burn Lichtenberg patterns in wood, he contacted the electrodes and sustained full-thickness electrical burns to the neck, chest, and bilateral upper extremities. Bilateral upper extremity fasciotomies were required on admission. Multiple subsequent operative procedures culminated with autografting to the majority of the wounds and ongoing complex reconstruction of the left thumb. In evaluating online news reports, we found 21 unique individuals with death or injury attributed to fractal woodburning. Four sustained substantial injuries, while 17 reportedly died. The first reported incident occurred in July 2016 and the most recent report was from July 2019. Ages ranged from 17 years old to the 60s. Eighteen individuals were younger than 50 years old. All of the mortalities and 3 of the 4 injuries occurred in males. Of the survivors, 3 sustained significant upper extremity injuries and 2 suffered cardiac arrest at the time of injury. The devices used in 4 incidents were microwave transformers and generated 2000 volts. Device characteristics were not identified in the remainder of cases. Conclusions Fractal woodburning is associated with devastating high-voltage electrical injuries and death. Prevention efforts should be focused on the potential risks of this art form. Applicability of Research to Practice News reports likely underestimate the actual incidence of injury and death due to fractal woodburning, however, even this limited data suggests an emerging public health problem requiring further study and public education.
