Effects of clinical application of free anterolateral thigh perforator lobulated flap in repair of electrical burn wounds on head based on the concept of donor site protection / 中华烧伤杂志

Objective: To explore the effects of clinical application of free anterolateral thigh perforator lobulated flap in repair of electrical burn wounds on head based on the concept of donor site protection. Methods: A retrospective observational study was conducted. Eight patients with electrical burns with huge scalp defects and exposed skulls were admitted to the First Affiliated Hospital of Zhengzhou University, from May 2017 to December 2019, who were all males, aged 21-57 (39±13) years, sustaining multiple deep partial thickness to full-thickness electrical burns to 5%-14% total body surface area. Among the scalp burn sites of the patients, 1 case was posterior occipital, 2 cases were parietal occipital, 4 cases were parietal temporal, and 1 case was frontotemporal. After debridement, the defect area was 10 cm×9 cm-16 cm×14 cm. The incision area of the free anterolateral thigh perforator lobulated flap was 22 cm×6 cm-30 cm×9 cm. The artery and vein of flap were anastomosed with superficial temporal artery and vein or facial artery and vein, and the other vein of skin flap was anastomosed with superficial vein of recipient area. The donor site of skin flap was closed by layer interrupted tension-reducing suture. After the operation, the survival of flop, donor site wound healing and complications were observed. The flap appearance, wound healing of donor sites, long-term complications and functional recovery of donor sites were observed on follow-up. Results: After the operation, the flaps of 8 patients survived completely without vascular crisis. The donor sites of flaps in all the patients healed well with no osteofascial compartment syndrome. Seven patients were followed up for 3 to 12 months, and 1 case was lost to follow up. During follow-up, the flaps of the patients' heads were in good appearance but with alopecia. The donor sites showed linear scars, which were well hidden. There were no significant differences in sensory and motor functions between the two sides, and no complications were found such as muscle hernia. Conclusions: Free anterolateral thigh perforator lobulated flap has a good clinical effect in the early repair of electrical burn wounds with huge scalp defect and skull exposure on head, and the donor wounds can be directly closed and sutured, greatly reducing the damage to the donor area.

Clinical effects of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns / 中华烧伤杂志

Objective: To explore the clinical effects of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns. Methods: A retrospective observational study was conducted. From May 2018 to April 2021, 12 male patients with thumb destructive defects caused by electrical burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 27 to 58 years, including 10 cases with degree Ⅲ thumb defect and 2 cases with degree Ⅳ thumb defect after thorough debridement. The thumb was reconstructed with free hallux-nail flap combined with composite tissue flap of the second phalangeal bone, joint, and tendon with skin island. The donor site of hallux-nail flap was covered with artificial dermis in the first stage and performed with continuous vacuum sealing drainage, and covered with medium-thickness skin graft from the groin site in the second stage. The donor site in the second toe was filled and fixed with iliac bone strips. The survival of reconstructed thumb was observed 1 week after the reconstruction surgery, the survival of skin graft in the donor site of hallux-nail flap was observed 2 weeks after skin grafting, and the callus formation of the reconstructed thumb phalanx and the second toe of the donor foot was observed by X-ray 6 weeks after the reconstruction surgery. During the follow-up, the shape of reconstructed thumb was observed and the sensory function was evaluated; the function of reconstructed thumb was evaluated with trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; whether the interphalangeal joints of the hallux and the second toe were stiff, the scar hyperplasia of the foot donor site, and whether the walking and standing functions of the donor feet were limited were observed. Results: One week after the reconstruction surgery, all the reconstructed thumbs of the patients survived. Two weeks after skin grafting, the skin grafts in the donor site of hallux-nail flap of 11 patients survived, while the skin graft in the donor site of hallux-nail flap of 1 patient was partially necrotic, which was healed completely after 10 days' dressing change. Six weeks after the reconstruction surgery, callus formation was observed in the reconstructed thumb and the second toe of the donor foot of 10 patients, the Kirschner wires were removed; while callus formation of the reconstructed thumb was poor in 2 patients, and the Kirschner wires were removed after 2 weeks of delay. During the follow-up of 6 to 24 months, the shape of reconstructed thumb was similar to that of the healthy thumb, the discrimination distance between the two points of the reconstructed thumb was 7 to 11 mm, and the functional evaluation results were excellent in 4 cases, good in 6 cases, and fair in 2 cases. The interphalangeal joints of the hallux and the second toe of the donor foot were stiff, mild scar hyperplasia was left in the donor site of foot, and the standing and walking functions of the donor foot were not significantly limited. Conclusions: The application of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns adopts the concept of reconstruction instead of repair to close the wound. It can restore the shape and function of the damaged thumb without causing great damage to the donor foot.

Colgajos de pedículo perforante en hélice para reconstrucción dearticulaciones mayores en secuelas de quemaduras / Perforator pedicled propeller flaps for big joins reconstruction in burns sequelaeperspective

Introducción: Las secuelas de quemadura juegan un papel fundamental en la recuperación del paciente quemado, ya que tiene una repercusión funcional y estética; para decidir el tratamiento de las contracturas cicatriciales, se necesita una evaluación cuidadosa y una clasificación de las contracturas por sitio, se debe explorar las articulaciones afectadas y notar los rangos de movilidad y las deformidades resaltando cualquier contractura cicatrizal y una vez que se establezca adecua-damente el tipo de secuela se tomara decisiones para orientar a un óptimo tratamiento. Los avances en el conocimiento de la anatomía vascular, en conjunto con el método de disección de colgajos "estilo libre", han permitido el desarrollo de los colgajos en hélice (propeller flap). Presentación de casos: Durante el período de un año (2018-2019) se presentaron seis casos de secuelas de quemaduras que comprometieron articulaciones mayores y que fueron tratadas con colgajo de pedículo perforante en hélice. La edad de los pacientes se ubicó entre 5 a 60 años con una mediana de 29 años con secuelas de quemaduras. Un caso con infección de sitio quirúrgico y seis sin complicaciones. El tiempo quirúrgico entre 120 a 170 min, la estancia hospitalaria tuvo una me-diana de 19 días (rango 6 a 55días). El diámetro del colgajo fue entre 24cm2 y 84cm2, con diferentes diseños lobulado (un caso), bilobulado (tres casos), tetralobulado (dos casos); permitiendo que el defecto secundario se cierre de forma directa en cinco de ellos y en un caso se colocara injerto de piel. Discusión: La literatura científica provee evidencia de las ventajas al utilizar colgajos en hélice por la capacidad de recons-trucción del tejido en un procedimiento de una sola etapa, logrando obtener resultados similares que ofrecen los colgajos libres microvascularizados.Conclusiones: El colgajo en hélice mejora las retracciones en las articulaciones mayores devolviendo el rango de movili-dad, preserva el músculo subyacente, proporciona una menor morbilidad del sitio donante.

Introduction: The sequelae of burns play a fundamental role in the recovery of the burned patient, since they have a func-tional and aesthetic impact; To decide on the treatment of scar contractures, a careful evaluation and classification of the contractures by site is needed, the affected joints should be explored and ranges of motion and deformities noted highli-ghting any scar contractures and once the type of sequel, decisions will be made to guide a better treatment. Advances in the knowledge of vascular anatomy, together with the "freestyle" flap dissection method, have allowed the development of propeller flaps. Case presentation: During a one-year period (2018-2019), there were six cases of burn sequelae that compromised major joints and that were treated with a pedicled propeller flaps. The age of the patients ranged from 5 to 60 years with a median of 29 years with burn sequelae. One case with surgical site infection and six without complications. The surgery time between 120 and 170 min, the hospital stay had a median of 19 days (range 6 to 55 days). The diameter of the flap was between 24cm2and 84cm2, with different designs: lobed (one case), bilobed (three cases), tetralobed (two cases); considering that the secon-dary defect is closed directly in five of them and in one case a skin graft is placed. Discussion: The scientific literature provides evidence of the advantages of using pedicled propeller flaps due to the ability to reconstruct the tissue in a single-stage procedure, achieving similar results as those offered by microvascularized free flaps.Conclusions: The pedicled propeller flaps improves retractions in major joints, restoring the range of motion, preserving the underlying muscle, and providing less donor site morbidity.

Retalho interósseo posterior reverso do antebraço para o tratamento cirúrgico do trauma elétrico da mão: relato de caso / Reverse posterior interosseous flap of the forearm for the surgical treatment of electric hand trauma: Case report

Introdução: Lesões que acometem as mãos com importante perda cutânea frequentemente requerem retalhos para cobertura precoce, visto que permitem melhor reabilitação. Dentre as opções, o retalho interósseo posterior reverso do antebraço é o mais utilizado para defeitos no dorso da mão e punho, com baixas taxas de complicações. Normalmente, esse retalho não é utilizado para a reconstrução de defeitos em região palmar, já que geralmente não alcança esse local. Relato de caso: Apresentamos o caso de um paciente com queimadura elétrica de terceiro grau, em palma da mão direita, cuja reconstrução foi realizada com o uso do retalho interósseo posterior reverso do antebraço, após debridamentos conservadores, no 14o dia após a queimadura. O paciente apresentou boa evolução pós-operatória, sem complicações ou sequelas funcionais a longo prazo. Conclusão: O retalho interósseo posterior reverso do antebraço permite cobertura adequada de lesões em palma da mão, preservando sua funcionalidade.

Introduction: Lesions affecting the hands with significant skin loss often require flaps for early coverage, as these permit faster healing. Among the various options, the reverse posterior interosseous flap of the forearm is most commonly used for defects involving the back of the hand and wrist due to low complication rates. Normally, this flap is not used for the reconstruction of defects in the palmar region since its distal reach is insufficient. Case report: We present the case of a male patient with third-degree electrical burns on his right palm, whose reconstruction was performed on the 14th day postinjury using the reverse posterior interosseous flap of the forearm after conservative debridement. The patient presented good postoperative evolution, without long-term complications or functional sequelae. Conclusion: The reverse posterior interosseous flap of the forearm permits adequate coverage of palm injuries, preserving its functionality.

Reconstrucción plantar con matriz de regeneración dérmica (Integra®) en paciente quemado eléctrico: presentación de un caso y revisión de la literatura / Plantar reconstruction with matrix of dermal regeneration (Integra®) in an electric burned patient: case report and literature review

Resumen Introducción: Las lesiones complejas de la cara plantar del pie son de difícil manejo desde el punto de vista reconstructivo. En la literatura el tratamiento de elección es la cobertura mediante colgajos libres. Nuestro objetivo es presentar el caso de un paciente con una lesión plantar compleja, exitosamente resuelta con el uso de matriz de regeneración dérmica (Integra®) e injerto dermoepidérmico. Caso clínico: Hombre de 35 años, que sufre quemadura eléctrica de alta tensión con lesión compleja plantar bilateral. Se manejó con escarectomías sucesivas hasta delimitar el daño tisular, y posterior cobertura con Integra® e injerto con resultado estético y funcional óptimo. Discusión: Aunque los colgajos libres son la elección en el tratamiento de esta zona anatómica, infrecuentemente son la única alternativa de reconstrucción en el paciente quemado. No hay mayor evidencia en la literatura en el uso de matrices dérmicas para la cobertura de este tipo de lesiones. Conclusión: Los autores consideran que el manejo de lesiones plantares complejas mediante el uso de matrices de regeneración dérmica es una alternativa válida a considerar en situaciones en que, por diversos motivos, no se puede ofrecer un colgajo libre.

Abstract Introduction: Complex wounds of the plantar aspect of the foot are difficult to manage in the reconstructive point of view. The standard of treatment is covering the defect with free flaps. Our goal is to present the case of a patient successfully treated with the use of matrix dermal regenaration Integra® and dermoepidermal graft for a complex plantar lesion. Clinical case: Thirty-five year old man, who suffers from high voltage electrical burn with bilateral plantar complex injury. It was handled with successive escharectomies to delimit tissue damage and subsequent coverage with Integra® and grafting with optimal aesthetic and functional results. Discussion: Although free flaps are the choice in the treatment of this anatomical area, they are infrequently the only reconstructive option in burned patients. There is no greater evidence in the literature on the use of dermal matrices to cover such injuries. Conclusion: The authors believe that the management of complex footpad lesions using dermal regeneration matrices are a valid alternative to consider in situations where for various reasons, free flaps can't be offered.

Queimaduras elétricas por alta voltagem: cinco anos de análise epidemiológica e tratamento cirúrgico atualizado / High-voltage electrical burns: five-year epidemiological analysis and updated surgical treatment

INTRODUÇÃO: Avaliar cinco anos de análise epidemiológica e tratamento cirúrgico atualizado das queimaduras elétricas por alta voltagem. MÉTODOS: Foi realizado um estudo descritivo, retrospectivo de corte transversal, no Centro de Terapia de Queimados Dr. Oscar Plaisant, do Hospital Federal do Andaraí, Rio de Janeiro, Brasil, no período de janeiro de 2009 a dezembro de 2014. Foi aplicado um formulário nos prontuários dos 38 pacientes incluídos no estudo, a fim de avaliar as variáveis definidas. RESULTADOS: Foram analisados 38 pacientes por queimadura elétrica de alta voltagem, sendo 95% dos casos do sexo masculino, com faixa etária entre 21-42 anos. O local de ocorrência mais frequente foi o trabalho, em 55,3%. A porcentagem de SCQ variou de 1-60%. A parte do corpo mais acometida foi a mão esquerda, em 55,26%. O preparo pré-cirúgico para autoenxertia foi necessário em 34,21%, sendo a média de tempo transcorrido 37,5 dias, o tipo de tratamento cirúrgico foi desbridamento seriado sob anestesia geral em 100%, autoenxertia em 31,6%, amputação em 18,4% e fasciotomia em 5,3% dos pacientes. A taxa de óbito foi de 0%. CONCLUSÕES: O estudo observou que as queimaduras elétricas ocorrem mais frequentemente em adultos jovens no local de trabalho, portanto, é necessário desenvolver políticas de sensibilização para a segurança no local de trabalho. Apesar da gravidade da lesão, pacientes com suporte clínico adequado e avaliação cirúrgica precoce têm mais probabilidade de sobreviver, mesmo com altas taxas de amputação, confirmando a necessidade de mais pesquisas sobre a eletroporação.

INTRODUCTION: Evaluation of a 5-year epidemiological analysis and updated surgical treatment of high-voltage electrical burns. METHODS: A descriptive, retrospective cross-sectional study was conducted in the Center of Burn Treatment Dr. Oscar Plaisant, Federal Hospital of Andaraí, Rio de Janeiro, Brazil, from January 2009 to December 2014. A form was applied to the medical records of 38 patients included in the study in order to assess the defined variables. RESULTS: In total, 38 patients with high-voltage burns were evaluated, 95% of whom were men aged between 21 and 42 years. The most frequent place of occurrence was the workplace in 55.3% of cases. The percentage of burned total body surface area ranged from 1% to 60%. The most affected part of the body was the left hand in 55.26% cases. Presurgical preparation for self-grafting was necessary in 34.21% subjects, and the mean time elapsed was 37.5 days. The type of surgical treatment was serial debridement under general anesthesia in 100% of the patients, self-grafting in 31.6%, amputation in 18.4%, and fasciotomy in 5.3%. The mortality rate was 0%. CONCLUSIONS: The study indicated that electrical burns occur most often in young adults in the workplace; therefore, policies should be developed to raise safety awareness in the workplace. Despite the severity of the injury, patients with adequate clinical support and early surgical evaluation are more likely to survive, even with high rates of amputation, confirming the need for more research on electroporation.

Padronização do tratamento cirúrgico do trauma elétrico na fase aguda / Standardization of surgical treatment of acute electrical trauma

INTRODUÇÃO: As queimaduras elétricas correspondem de 5 a 15% dos casos de acidentes com queimaduras. A maioria está associada a acidentes do trabalho, nos quais predominam as lesões com alta voltagem (acima de 1.000 Volts), em pacientes do sexo masculino. As taxas de mortalidade variam de 2 a 15%, nos mais diversos centros de queimados. O objetivo é revisar padronização das etapas cirúrgicas na fase aguda de desbridamento (primeiros 15 dias) pela comparação de dosagem de creatofosfoquinase, hidratação venosa e fotografias para a aplicação de uma rotina de etapas cirúrgicas. MÉTODOS: Trata-se de um estudo quantitativo, prospectivo, realizado em um hospital público da cidade de Fortaleza, CE, entre julho de 2013 a dezembro de 2015. A população foi composta por adultos jovens, entre 15 e 50 anos, de ambos os sexos, vítimas de queimaduras por choque elétrico, com lesão de terceiro grau, no mínimo muscular. RESULTADOS: Foram realizados 12 procedimentos cirúrgicos de amputações nos 15 pacientes do estudo (60%). Seis pacientes não sofreram amputação (40%). Um paciente sofreu três procedimentos de amputação no mesmo membro (pododáctilo, pé e coxa esquerdos) e outro, duas amputações em membros superiores distintos. CONCLUSÃO: O tratamento na fase aguda do choque elétrico deve incluir uma imediata e adequada reposição líquida venosa, associada com procedimentos cirúrgicos de desbridamentos e de amputações, o mais precoce possível, em etapas com intervalos de 48 a 72 horas.

INTRODUCTION: Electrical burns are responsible for 5% to 15% of cases of burn accidents. The majority is associated with workplace accidents, in which high-voltage injuries (>1,000 V) predominate in male patients. The mortality rates vary from 2% to 15% in different burn centers. The objective is to review the standardization of surgical steps in the acute phase of debridement (the first 15 days) by comparison of creatine phosphokinase levels, intravenous hydration, and photographs to implement routine surgical stages. METHODS: This was a quantitative, prospective study performed in a public hospital in the city of Fortaleza, Brazil, between July 2013 and December 2015. The population was composed of young adults between 15 and 50 years, of both sexes, who experienced electrical burns, with third-degree injuries and muscle involvement. RESULTS: Of the 15 patients in the study, 9 (60%) patients underwent 13 surgical amputation procedures and 6 (40%) patients did not undergo amputation. One patient underwent three amputation procedures in the same limb (toe, foot, and thigh) and another patient underwent two amputations in the upper limbs. CONCLUSION: Treatment in the acute phase of electrical shock must include immediate and adequate intravenous fluid replacement, along with surgical procedures of debridement and amputations, as early as possible, in steps with intervals of 48 to 72 hours.

Quemaduras de cuero cabelludo: serie de casos y revisión de la literatura / Scalp burns: experience in 11 cases

Background: The scalp is the most external and important barrier of the skull and brain. Its burns are often caused by high voltage injuries, fire, liquid or other heat sources. Aim: To report a series of cases of scalp burns seen during the last 10 years. Material and Methods: Retrospective review of medical records of patients that required hospital admission with a main diagnosis of scalp burn. Results: There were 2.266 consultations for head burns. Of these, 34 patients consulted with scalp burns and 11 were hospitalized. Four were due to electrical burns and four due to fire. As treatment in one case, a free flap was used but failed and required local advancement flaps. For the management of sequelae, expanders and then local advancement flaps were used. Conclusions: Only a small proportion of patients presenting with head burns, had scalp burns. Most were treated as outpatients and did not require further action. The four patients with electrical burns required more aggressive treatments. For the management the sequelae, expanders and local advancement flaps were used.

Utilization of skin flap for reconstruction of the genitalia after an electric burn

The objective of this article is to describe a case of an electric burn to the genitalia causing scrotal and testicular lesion, and the subsequent reconstruction using a skin graft. The patient was a 10-year-old boy who was victim of an electric burn that harmed the genitalia. There was extended skin loss, penile, scrotal and partial testicular lesion. The treatment consisted of plastic surgery to reconstruct the genitalia with skin flaps grafted on the left thigh, the scrotum and the base of the penis. The patient recovered well and was discharged after two weeks. We concluded that in severe cases of electric burns to the genitalia, skin graft offer a good therapeutic option.

Reconstruction de la verge apres necrose due a une cireoncision

The total necrosis of penis is a serious complication of circumcision using the electric bistoury. The penis reconstruction was achieved by mobilization of the erectil. body and its detachment from the ischio-pubic branches. In order to avoid recurrence of its adherence to the ischio-pubic branches and to ensure the cutaneous covering of penis, the latter was placed in a scrotal tunnel. After a six-month follew-up, we noted that the child had a good urinary stream and spontaneous erections
