RESUMO
Burns affect 11 million people worldwide annually. Electrical burns (EBs) are renowned for inflicting extensive harm and long-term consequences that can lead to severe illnesses and fatalities. People in both occupational and nonoccupational settings may be exposed to EBs, leading to functional or anatomical consequences. We identified sociodemographic features related to EBs in both settings. A cross-sectional design, using an open dataset of electrical shock injuries that occurred in Colombia during the 2010-2021 period, was carried out. Sociodemographic features of people injured in occupational and nonoccupational settings were described in counts (%), incidence per 100 000 people (I0; 95% CI). To identify related factors (age-sex adjusted) with injuries in occupational and nonoccupational settings, we applied a binary logistic regression. Over the 12-year period, there were 1.274 EBs (I0: 2.47; 2.34-2.61), 287 in the occupational setting (I0: 1.35; 1.20-1.51), and 987 in the nonoccupational setting (I0: 3.25; 3.05-3.46). Age median was 31 years, and most cases were distributed in middle adulthood (52.8%), males (88.1%), high school/technician (42.8%), urban location (73.7%), weekdays (95.3%), and daytime hours (85.5%). Factors related to EBs in the occupational setting were males, middle adulthood, high school/technician, Thursday, and daytime hours. Other factors related to EBs in the nonoccupational setting were early childhood, primary school, urban location, and weekends. Both settings pose a risk of injuries to individuals. We have identified sociodemographic factors related to these injuries in both occupational and nonoccupational settings, which could aid in preventing damages and long-term complications, especially among vulnerable subgroups such as those determined above.

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.

High-voltage electrical burns are potentially devastating and they are associated with significant morbidity and mortality. Due to vascular damage and progressive tissue necrosis produced by electrical burns, there is a large controversy regarding the ideal reconstructive technique for cutaneous coverage of severe lesions in the upper limb. This study aims to analyze our experience using the McGregor inguinal flap technique, for the coverage of large soft tissue losses produced by high-voltage electric burns in the upper limb. We performed a retrospective descriptive study with patients diagnosed with high-voltage electric burns, in which the McGregor inguinal flap technique was used to cover severe lesions in the upper limb. This study was performed at the department of Reconstructive Plastic Surgery and Burns of the Specialist Hospital Eugenio Espejo, from January 2016 to December 2017. The flap technique was performed on twelve patients, out of which, nine were males with a mean age of 33 years old. Furthermore, nine out of the twelve cases occurred as a result of accidents at work. The mean time elapsed between the lifting of the flap, closure of the donor area, and fixation of the flap to the affected area was 56 minutes (44-72 minutes). In the immediate postoperative period, three patients presented signs of infection in the surgical area. No total dehiscence, total necrosis, and/or hematoma were reported in all patients. The success limb salvage rate was 100%. In our experience, the McGregor inguinal flap technique presented a favorable postoperative evolution with complete closure of the lesions and a low rate of complications. Due to the limitations of this study, more studies are needed to prospectively evaluate this flap.
RESUMO
OBJECTIVE: Pediatric burns are preventable with legislative and infrastructural changes. Although retrospective audits of many low- and middle-income countries have aided preventative efforts, the epidemiological status of burns in the Caribbean is not known. This study characterizes pediatric burns in the Dominican Republic (DR) and compares these to age-matched North American records captured by the National Burn Repository. METHODS: A retrospective audit of 1600 patients admitted to the Unidad de Niños Quemados Dra. Thelma Rosario Hospital, the island's only major pediatric burn center, between January 2010 to March 2017 was performed. Epidemiological variables analyzed included age, gender, burn mechanism, year, month, city, admission duration, nationality, mortality, and %TBSA. RESULTS: Pediatric burn patients in the DR sustained larger burns (8.2% vs. 6.5% TBSA) and spent more days in the hospital (10 vs. 6 days). Females were overrepresented (M:F=1:1.5) and mortality amongst admitted patients was 4-fold higher (2.8% vs. 0.7%). Electrical burns were significantly overrepresented in DR (21%) compared to age-matched North American patients (2%). Although electrical burns were smaller (4% TBSA), compared to scald (14% TBSA), and flame (19% TBSA), these burns preferred hands and had a high mortality rate (3%). No significant seasonality in burn mechanisms were observed. Finally, we report geographical and age group differences in the distribution of burn mechanisms and highlight particularly vulnerable subpopulations. CONCLUSION: This investigation identifies a demographical profile where electrical burns account for a significant percentage of the burn population. This provides a basis for concentrating preventative efforts in vulnerable populations.

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.

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.

OBJECTIVES: To describe the demographic, risk factor, occupational, and morbidity and mortality characteristics of burns in adults in Ecuador using national data. These data are from the only specialized public hospital in Ecuador that has a 12-bed burn unit. METHODS: The National Institute of Statistics and Census provided data from the burn unit of the Hospital Eugenio Espejo, in Quito. Three different datasets pertaining to burn deaths, burn unit inpatient admissions, and hospital discharge were analyzed. Patients who died or were discharged before entering the burn unit were not included in this analysis. RESULTS: During the 10-year period, 1106 patients were admitted to the burn unit, men represent 69.37% with 768 cases and women represent 30.62% with 337 patients; the number of patients per year was on average 123 cases; the average age was 33-34 years old, with a range between 16 and 96 years old. Heat (thermal) burns represent 65.78% followed by electrical with 30.53%, friction burns with 2.06%, and chemical burns with 1.62%. Domestic methane gas was the most frequent agent causing thermal burns and the most affected occupational groups are construction workers and people who stay at home. The overall mortality is 10.2% and the average length of stay was 23 days. CONCLUSIONS: Thermal burns are more frequent than any other cause of burns. Electrical burns are more frequent in Ecuador than anywhere else according to our research, meaning that control and prevention of workplace safety, urban planning, and home safety are scarce. The most affected groups are those dedicated to labor work. Finally, mortality in hospitalized patient is higher when compared with developed countries.

Paciente del sexo masculino de 43 años de edad, con antecedentes de hipertensión arterial, que hace contacto con los cables de alta tensión (33 000 V); el sitio de entrada de la electricidad se produjo por dos regiones, lo cual causó lesiones del 30,80 % de superficie corporal quemada y pronóstico de vida crítico; las zonas de salida fueron ambos calcáneos. Se decidió ingreso del paciente en Terapia Intensiva de Caumatología. Por la complejidad de las lesiones de las puertas de entrada, se amputó de urgencia la mano izquierda y a las 48 h el dedo pulgar de la mano derecha. Por la profundidad de las quemaduras, se requirió varias intervenciones: amputaciones, necrectomías y autoinjertos de piel. La estadía hospitalaria fue de 125 días. Hubo daño irreversible de todos los nervios de la mano derecha, con impotencia funcional total. La inmediatez de la atención especializada por un equipo interdisciplinario salva la vida del paciente, con secuelas estéticas y funcionales. La electricidad produce lesiones severas que requieren de un manejo integral y cuando la puerta de entrada es múltiple, se incrementa la complejidad del caso.
A 43 years old male patient with antecedents of high blood pressure that makes contact with high voltage cables (33 000 V) was taken to hospital. The input site of electricity was produced in two regions of the body, causing lesions of a 30,80 % of burned body surface and a critical prognosis for his life; being the calcanei the output sites. It was decided to admit the patient to the Intensive Care Burn Unit. Due to the complexity of the lesions in the input sites, his left hand was amputated as an emergency treatment and 48 hours later, the thumb of his right hand was amputated, too. Because of the depth of burns, several interventions were required: amputations, necrectomies, and skin autografts. He was in hospital for 125 days. He had irreversible damage of all the nerves of the right hand, with total functional impotence. The immediacy of the specialized attention given by a multidisciplinary staff can save a patient's life, leaving functional and aesthetic sequels. Electricity produces severe lesions that require a comprehensive management and, when the input site is multiple, the complexity of the case is higher.
