Therapeutic approach to electric burn with platelet rich plasma, grafts and hyperbaric oxygenation / Enfoque terapéutico de quemadura eléctrica con plasma rico en plaquetas, injertos y oxigenación hiperbárica

Abstract Contact electrical burns are more severe than other forms of contact burn injury. Moreover, treatment of hand burns is an important therapeutic challenge. We present a 17 year-old female of low voltage electric hand injury, admitted 5 days after injury. The patient was treated with autologous platelet rich plasma, porcine dermis heterograft and partial autologous skin graft, all of them with hyperbaric oxygen therapy (HBOT) at 1.45 ATA ≈100% O2 like adjuvant therapy. Good evolution and acceptable aesthetic results were reported. Although more studies are required, we suggest that multi-therapeutic approach could be effective in treatment for electric burns in hands.

Resumen Las quemaduras eléctricas por contacto son más graves que otras formas de quemaduras. Además, el tratamiento de las mismas en las manos es un importante desafío terapéutico. Presentamos el caso de una mujer de 17 años de edad con lesión en la mano por quemadura por electricidad de baja tensión. Fue ingresada 5 días después de la lesión y tratada con plasma rico en plaquetas autólogo, heteroinjerto de dermis porcina e injerto de piel autólogo parcial, todo con oxigenoterapia hiperbárica (TOHB) a 1.45 ATA ≈100% O2 como terapia adyuvante. Tuvo buena evolución y resultados estéticos aceptables. Aunque se requieren más estudios, sugerimos que el enfoque multi-terapéutico podría ser eficaz en el tratamiento de las quemaduras eléctricas en las manos.

Management of Critical Burn Injuries: Recent Developments / 대한중환자의학회지

BACKGROUND: Burn injury and its subsequent multisystem effects are commonly encountered by acute care practitioners. Resuscitation is the major component of initial burn care and must be managed to restore and preserve vital organ function. Later complications of burn injury are dominated by infection. Burn centers are often called to manage problems related to thermal injury, including lightning and electrical injuries. METHODS: A selected review is provided of key management concepts as well as of recent reports published by the American Burn Association. RESULTS: The burn-injured patient is easily and frequently over resuscitated, with ensuing complications that include delayed wound healing and respiratory compromise. A feedback protocol designed to limit the occurrence of excessive resuscitation has been proposed, but no new “gold standard” for resuscitation has replaced the venerated Parkland formula. While new medical therapies have been proposed for patients sustaining inhalation injury, a paradigm-shifting standard of medical therapy has not emerged. Renal failure as a specific contributor to adverse outcome in burns has been reinforced by recent data. Of special problems addressed in burn centers, electrical injuries pose multisystem physiologic challenges and do not fit typical scoring systems. CONCLUSION: Recent reports emphasize the dangers of over resuscitation in the setting of burn injury. No new medical therapy for inhalation injury has been generally adopted, but new standards for description of burn-related infections have been presented. The value of the burn center in care of the problems of electrical exposure, both manmade and natural, is demonstrated in recent reports.

A Case of Paroxysmal Atrial Fibrillation after Electric Injury / 대한내과학회지

Electrical injuries can cause cardiac abnormalities, ranging from dysrhythmias to myocardial infarction. Atrial fibrillation after electrical injury is extremely rare. The mechanisms underlying electrical current-induced arrhythmias are unclear. However, due to differences in electrical resistance, current travels preferentially along blood vessels and nerves, making the heart the most susceptible organ to electrical injury. Cardiac arrhythmias may occur at the time of electrical injury or later, but most occur within the first day of injury. Almost all patients described in previous reports with atrial fibrillation developed the condition after high voltage injuries (> 1,000 V). In our case, however, atrial fibrillation developed after a low voltage injury (220 V). Atrial fibrillation was detected and the rate was controlled with intravenous digoxin infusion. A normal sinus rhythm was restored 21 h after the electrical injury.

Reconstruction of Hand Using Peroneal Perforator Free Flap in High-Voltage Electrical Burn Patients

PURPOSE: The hand is frequently affected area in high voltage electrical burn injury as an input or output sites. Electrical burn affecting the hand may produce full thickness necrosis of the skin and damage deep structures beneath the eschar, affecting the tendon, nerve, vessel, even bone which result in serious dysfunction of the hand. As promising methods for the reconstruction of the hand defects in electrical burn patients, we have used the peroneal perforator free flaps. METHODS: From March 2005 to June 2006, we applied peroneal perforator free flap to five patients with high tension electrical burn in the hand. Vascular pedicle ranged from 4cm to 5cm and flap size was from 4x2.5cm to 7x4cm. Donor site was closed primarily. RESULTS: All flaps survived completely. There was no need to sacrifice any main artery in the lower leg, and there was minimal morbidity at donor site. During the follow-ups, we got satisfactory results both in hand function and in aesthetic aspects. CONCLUSION: The peroneal perforator flap is a very thin, pliable flap with minimal donor site morbidity and is suitable for the reconstruction of small and medium sized wound defect, especially hand with electrical burn injury.
