Lower trapezius myocutaneous flap repairs adjacent deep electrical burn wounds

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.

Changing Tendencies of Patients with Electrical Burns in Lithuania from 2016 to 2020

“…Aukštos įtampos elektros sukeltos nudegimo traumos, susijusios su elektros srove, tekėjusia per visą žmogaus kūną, -tai dideli sužalojimai (neretai kelių organų sistemų), lemiantys širdies aritmiją ir gilias raumeninio audinio nekrozes [5,8,10]. Priklausomai nuo elektros srovės įtampos dydžio, trauminių nudegimų sukeltas vietinis audinių pažeidimas dažnai yra gilus ir sunkus, pažeidžiantis sausgysles, nervus, svarbias kraujagysles, kaulus ir sąnarius, todėl žaizdų gydymas yra sudėtingas [11]. Elektros sukelti nudegimai gali lemti didžiulę skeleto raumenų nekrozę -rabdomiolizę (skersaruožių skeleto raumenų ląstelių irimas), taip pat inkstų nepakankamumą (pasireiškė 12,7 proc.…”

Uso De Retalhos Microcirúrgicos Em Pacientes Queimados

“…No entanto, algumas complicações também podem estar presentes na confecção de tais retalhos, como trombose venosa do retalho, infecção, epidermólise, disestesia, deiscência parcial de sutura e necrose parcial do retalho (FANTINI et al, 2014). Algumas técnicas específicas de uso de retalhos miocutâneos podem auxiliar em um melhor prognóstico como evitar exceder à necessidade de corte do músculo, garantir que o suprimento de sangue do retalho atenda às necessidades de reparação da ferida, e reparar o local doador com pele de espessura média (MENG et al, 2020).…”

“…Por isso, deve ocorrer uma seleção específica para os pacientes que podem ser submetidos a esse procedimento. Como por exemplo, a estabilidade clínica e a passagem por exames regulares no local do ferimento (MENG et al, 2020).…”
