Rhabdomyolysis and vascular thrombosis supporting the electrocution related death.

INTRODUCTION: Electrocution related death remains an ambiguous judgement and requires numerous valid evidence for proper medico-legal diagnosis. While the presence of electrical burn marks is a significant macroscopic indicator, it can be absent, especially on moist skin. The electrical mark still represents a fundamental indicator above all in the medico-legal field, but the identification of pathognomonic elements and signs not limited to the skin alone could be a valid help in the future, especially in unclear cases. CASE REPORT: The deceased was brought-in-dead to the hospital from their workplace, with no signs of fatal natural diseases. External examination revealed a Y-shaped burn mark on the right side of the neck and collapsed blisters with greying rings on both heels. Internal examination showed no alarming findings. Further, histopathological analysis of the foot blisters and neck burn revealed intraepidermal detachment, elongated nuclei, and coagulative necrosis. Notably, the presence of muscle fibre casts in kidney tubules and microthrombi in lung sections which indicate rhabdomyolysis and vascular thrombosis supported electrocution-related death. CONCLUSION: These positive findings of the electrical burn marks externally and significant histopathological changes, collectively support the death was due to electrocution, after excluding any major, fatal injuries. Albeit, a detailed inspection of the crime scene plays an important role, in order to classify the electrocution related death.

A Consequence of an Electrical-Burn Injury: Atrial Fibrillation.

Cardiac arrhythmias following electrocution injuries can accompany high-voltage or high- intensity currents. Contributing factors to electrical hazard are the type of current, voltage, resistance, and duration of contact and pathway through the body. It is important to monitor for delayed arrhythmias in patients with an electrical injury. We describe a case of a 52-year-old man who presented after an electrical shock injury while grabbing a 5,000-voltage wire at work. In this case report, we discuss the presentation, management, and follow-up recommendations for this type of injury.

Extracorporeal Life Support Use in Mixed Distributive-Obstructive Shock Following an Electrical Injury: A Case Report.

Electrical burn injuries can be catastrophic, threatening severe disability or mortality. We present a patient who suffered from electrical shock, requiring bilateral above-knee amputations, right trans-radial amputation, renal replacement therapy, and veno-arterial extracorporeal life support (VA ECLS) therapy. While there exist reports of cases that have demonstrated the potential use of ECLS in burn patients with cardiogenic shock or acute respiratory distress syndrome, this is a unique case of VA ECLS use for an electrical injury patient who developed mixed distributive-obstructive shock secondary to pulmonary embolism and sepsis. Given the wide variety of morbidities that can result from electrical burns, VA ECLS is a promising tool for those who require cardiopulmonary support refractory to traditional measures.

Suspected Burn From a 9-Voltage Battery.

Advancements in technology allow for the utilization of low-voltage battery-powered devices for patients admitted to the hospital. There have been rare cases of burns due to leakage of the internal contents from low-voltage batteries, but to date, there have been no reports of electrical burns caused by low-voltage batteries. We present the case of an 89-year-old female who presented to the general surgery service with a suspected electrical burn from laying on a 9-volt battery. The patient underwent operative debridement with no evidence of a deeper injury. The patient continues to follow up with an outpatient wound clinic and is healing well. This case highlights the importance of teaching and raising awareness of all small devices that may become entangled or lost in patients' linens, such as 9-volt telemetry batteries, to prevent harm.

Electrical injuries and outcomes: A retrospective review.

Electrical burns (EI) differ from other burn injuries in the immediate treatment given and delayed sequelae they manifest. This paper reviews our burn center's experience with electrical injuries. All patients with electrical injuries admitted from January 2002 to August 2019 were included. Demographics; admission, injury, and treatment data; complications, including infection, graft loss, and neurologic injury; pertinent imaging, neurology consultation, neuropsychiatric testing; and mortality were collected. Subjects were divided into those who were exposed to high (>1000 volts), low (<1000 volts), and unknown voltage. The groups were compared. P < 0.05 was considered significant. One hundred sixty-two patients with electrical injuries were included. Fifty-five suffered low voltage, 55 high voltage, and 52 unknown voltage injuries. High voltage injuries were more likely to be male (98.2% vs. 83.6% low voltage vs. 94.2% unknown voltage, p = 0.015), to experience loss of consciousness (69.1% vs. 23.6% vs. 33.3%, p < 0.001), cardiac arrest (20% vs. 3.6% vs. 13.4%, p = 0.032), and undergo amputation (23.6% vs. 5.5% vs. 8.2%, p = 0.024). No significant differences were observed in long-term neurological deficits. Twenty-seven patients (16.7%) were found to have neurological deficits on or after admission; 48.2% recovered, 33.3% persisted, 7.4% died, and 11.1% did not follow-up with our burn center. Electrical injuries are associated with protean sequelae. Immediate complications include cardiac, renal, and deep burns. Neurologic complications, while uncommon, can occur immediately or are delayed.

Static and Dynamic Stabilization of the Shoulder After Total Scapulectomy in an Electric Burn Patient.

ABSTRACT: An otherwise healthy 49-year-old man experienced a high-voltage electrical injury to the left shoulder resulting in total scapulectomy, partial calviculectomy, and a substantial soft tissue defect. The majority of the muscles around his shoulder were debrided because of necrosis, with only the pectoralis and latissimus dorsi muscles remaining attached to the humerus. Surprisingly, the patient's brachial plexus remained intact, and his left elbow, wrist, and hand function were preserved. A novel combination of 3 static and dynamic suspension techniques were used to stabilize his shoulder and prevent traction injury to the brachial plexus. Postoperative follow-up at 1 year demonstrated excellent stability of his reconstructed shoulder, which allowed him to ambulate independently and return to employment.

Predictors for limb amputation and reconstructive management in electrical injuries.

BACKGROUND: Electrical injuries follow a specific pathophysiology and may progressively damage both skin and deeper tissues, frequently ending in amputations. Type and timing of soft tissue reconstruction after electrical burns is crucial for proper outcome. The aim of this study was to assess surgical management and outcome of patients with electrical injuries treated at the Zurich Burn Center over the last 15 years, with emphasis on risk factors for amputation and reconstructive strategy. METHODS: Patient charts were reviewed retrospectively to identify cases admitted at the Zurich Burns Center (2005-2019). Patient characteristics and surgical management, with a special focus on amputations, reconstruction and outcome were analyzed and risk factors for amputation were assessed. RESULTS: Eighty-nine patients were identified and a total of 522 operations were performed. Escharotomy and fasciotomies were performed in 40.5% and 24.7% of cases, respectively, mainly at admission. The total amputation rate was 13.5% (23 amputations, 12 patients). Development of compartment syndrome, rhabdomyolysis, high myoglobin and CK blood levels, kidney failure, sepsis and respiratory complications during the course were related to higher risk of amputation (p < 0.001). Sixty-six flap-based reconstructions were performed (25% cases): 49 loco-regional flaps, 3 distant pedicled flaps, 14 free flaps. Two flaps were lost (flap failure rate 14%). Both flap losses occurred in cases of early reconstruction (within 5-21 days). CONCLUSIONS: Electrical injuries are still cause of elevated morbidity and mortality, with high amputation rate. Predictors for amputation can support physicians in the surgical care and decision-making. Reconstruction remains challenging in this type of injury: the surgical management with early decompression, serial necrectomies and delayed early reconstruction remains the procedure of choice at our unit.

We Got Your Back: Evaluating Recovery Following Spinal Cord Injury After High-Voltage Electric Burns.

Delayed spinal cord injury (SCI) is a relatively rare consequence of high voltage electrical burns, but it holds significant implications for patient quality of life. Due to the uncommon nature of delayed SCI and variable time of onset following injury, providers are currently unable to provide a prognosis for functional recovery and optimize a therapy process tailored to treat this patient populace. In this study, we aim to better map the pattern of recovery in these patients to better inform future rehabilitation practices. A retrospective chart review of five patients who experienced delayed SCI secondary to an electrical burn was conducted. The majority of patients displayed an upward trajectory in motor function following acute hospitalization and inpatient rehabilitation, with four of the five patients able to achieve complete motor strength in multiple extremities. In addition, rehabilitation was shown to have a noticeable impact in improving functional independence in tasks related to nursing. In conclusion, the clinical and functional outcomes of these delayed SCI patients point to the need for multidisciplinary management following injury and highlight the importance of early rehabilitation in regaining function.

Outcome of burn injury and associated factor among patient visited at Addis Ababa burn, emergency and trauma hospital: a two years hospital-based cross-sectional study.

BACKGROUND: Burn is one of the critical health problems worldwide. Developing countries with sub-Saharan and Asian populations are affected more. Its mortality and non-fatal complications depend on several factors including age, sex, residency, cause, the extent of the burn, and time and level of care given. OBJECTIVE: The purpose of this study was to assess the outcome of burn injury and its associated factor among patients who visited Addis Ababa burn emergency and trauma hospital. METHODS: The institutional-based, retrospective cross-sectional study design was conducted from April 1, 2019, to March 30, 2021. After checking the data for its consistency the data were entered and analyzed by using SPSS version 25. A total of 241 patients who had visited Addis Ababa burn, emergency and trauma Hospitals after sustained burn injury were recruited through convenience sampling method for final analysis. Model goodness-of-fit was checked by Hosmer and Lemeshow test (0.272). After checking multi-collinearity both the bi-variable and multivariable logistic regression model was fitted and variables having a p-value less than or equal to 0.05 at 95% CI in the multivariable analysis were considered statistically significant. RESULT: Adults (age 15 to 60 years) are the most affected groups accounting for 55.2% followed by pediatric age groups (age <15 years) (43.6%) and the elderly (age > 60 years) (1.2%). Scald burn was the major cause accounting for 39 % followed by Flame burn (33.6%), Electrical burn (26.6%), and chemical burn (0.8%). The mean TBSA% was 15.49%, ranging from1% to 64%. Adult males are more affected by electrical burns while adult females and the elderly encounter flame burn. 78.4% of patients were discharged without complications, 14.9% were discharged with complications and 6.6% died. The commonest long-term complication is the amputation of the extremity (19, 7.9%). Age greater than 60 years and TBSA% greater than 30% is a strong predictors of mortality with odds of 2.2 at 95% CI of [1.32, 3.69] and 8.7 at 95% CI of [1.33, 57.32] respectively. CONCLUSION AND RECOMMENDATION: The mortality rate show decrement from previous studies. Overall scald burn is common in all age groups but electrical burns and flame burns affected more adult and elderly age groups. Extremities were by far, the commonest affected body parts. The extent of burn injury and the age of the patient independently predict mortality. Early intervention will reduce mortality and complications.

Anterolateral Thigh Flap for Low-Voltage Fourth-Degree Electrical Burn Injury With Immediate Radial Nerve Palsy at the Elbow: A Case Report.

While high-voltage electrical injuries usually cause severe burn wounds and axonal polyneuropathy, low-voltage electrical injuries cause limited cutaneous wounds and demyelinating mononeuropathy, of which the median and ulnar nerves are the most commonly involved. We present the case of a 42-year-old man who suffered a 480-voltage electrical injury at his right elbow, resulting in a 24 × 10 cm fourth-degree burn wound and immediate radial nerve palsy. The burn wound was debrided with confirmation and preservation of radial nerve continuity. The wound was covered with a free anterolateral thigh flap and it healed uneventfully. The Tinel's sign continued to advance at follow-up, and electrodiagnostic studies showed progressive reinnervation. His radial nerve function recovered completely in 9 months. This is a rare case of low-voltage electrical injury with a fourth-degree burn wound and immediate radial nerve palsy. We treated the wound aggressively with early debridement and prompt flap coverage, but conservatively treated the radial nerve injury. The nerve recovery course indicates that it had a "shocked-cooked" injury and served itself as a well-placed nerve graft for the subsequent regeneration. We believe that our successful outcome in this case can provide more insights into the management of such injuries.

Epidemiology and factors associated with acute stress disorder in burned patients: a case-control study.

INTRODUCTION: A burn injury is a very painful experience, with subsequent emotional problems, which have been gaining relevance to the extent that survival from burns has improved. Among the alterations of the mental sphere in this population is Acute Stress Disorder (ASD) that has been described in up to one-third of patients with major burns. METHODOLOGY: A nested case-control study was carried out in a cohort of hospitalized patients in a burn referral unit, in patients over 16 years of age. A total of 135 patients, 41 cases, and 94 controls were included. All of them underwent a psychiatric interview, a standardized form was filled out on sociodemographic and clinical information, and the PID-5-BF scale was applied to evaluate associated personality elements. The diagnosis of acute stress was made with the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. RESULTS: The incidence of acute stress was 23.4%. When the clinical and sociodemographic characteristics of both the cases and the controls were compared, the risk factors were subsidized insurance, flame burn, burn in a special area, third-degree burn, high pain, stay in the Intensive Care Unit (ICU), peritraumatic amnesia and life threat. Patients also had a higher percentage of burned body surface, higher average pulse, longer hospital length of stay, higher average in the negative affect variable and in the psychoticism variable of the PID-5-BF scale. But for the multivariate analysis using logistic regression, the model that best explains the presence of acute stress only includes the variables life threat (Odds Ratio adjusted (ORa): 117.0; Confidence Interval (CI): 10.9-1258.5), severe pain (ORa: 9.9; CI: 1.8-52.8), electrical burn (ORa: 20.8; CI: 17.2-250), burn in a special area (ORa: 8.9; CI: 1, 0-76.8), third-degree burn (ORa: 10.4; CI: 0.7-166.7). CONCLUSION: Acute stress disorder is frequent in the hospitalised burn population, and is more frequent than in other types of trauma. Associated factors with the presentation of Acute Stress Disorder are the feeling of life threat at the time of the burn, having pain classified as strong (Visual Analog Scale (VAS) 5-10), electrical burn, and burns in special areas.

Evaluation of the Epidemiological Characteristics of the Patients Admitted to Our Clinic as a Result of Electric Shock.

Electric shocks (ESs) are common traumas in burn units that require treatment by specialists due to high mortality and morbidity. This study aimed to investigate the demographic and clinical characteristics of patients of ES, complications, and injury-related mortality and morbidity rates. The authors retrospectively analyzed data of 432 ES patients treated at the Gazi Yasargil Training and Research Hospital Burn Center, Turkey, between January 2010 and December 2020. Of the 432 patients, 92 (21.3%) and 340 (78.7%) sustained high- and low-voltage injuries, respectively. While high-voltage burns were common in January and December, low-voltage burns peaked in September and July. Burn patients were mostly males and were between the ages of 19 and 59 years. The majority of the ES events occurred at home. All four patients who died had suffered high-voltage burns, with two of high-voltage burns (2.17%) requiring amputation. None of the patients with low-voltage burns underwent amputation. High-voltage injuries manifested with larger burn surfaces, longer hospitalization, and more complications. Electrical injuries are largely preventable with simple safety precautions in daily life as well as serious consideration of workplace safety.

Low-Voltage Electricity-Associated Burn Damage of Lung Parenchyma: Case Report and Literature Review.

BACKGROUND: Electrical injuries are common in daily life. The severity of electrical injury depends on the electric current, and assessing electrical damage is difficult because there appears to be no correlation between skin burns and visceral injury. We report a case of bilateral lung injury with pulmonary hemorrhage after exposure to low-voltage electricity. CASE REPORT: A 23-year-old man was shocked by a low-voltage (110 V) electric current while at work. He had temporary loss of consciousness and twitching in the extremities, but soon regained consciousness and spontaneously stopped twitching. Electrical burn wounds were discovered on his back and forehead. Dyspnea and hemoptysis were noted. A computed tomography scan of the chest revealed patchy infiltration and consolidation of both lungs. The patient received treatment of tranexamic acid and prophylactic antibiotics for electricity-induced lung injury and pulmonary hemorrhage. Resolution of chest radiograph abnormalities was recorded on day 7. The mild dyspnea ceased approximately 2 weeks later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Electricity-induced lung injury should be considered in patients with electrical injury through a suspicious electrical current transmission pathway, respiratory symptoms, and corresponding imaging findings. Pulmonary complications can be serious and require early intervention.

Delayed Spinal Cord Injury From Electrical Burns: Two Cases.

Spinal cord injury has been described in only 2% to 5% of electrical injuries. When its presentation is delayed for several days to weeks after the initial injury, recovery is not the rule. Herein, we describe two patients who developed spinal cord injury from electrical burns. Case 1: A 60-year-old male presented with a 40% TBSA after contacting a power line. On hospital day 6, he developed lower extremity weakness that progressed to flaccid paralysis. Case 2: A 58-year-old male sustained a 9% TBSA high-voltage injury. On hospital day 2, he started to have progressive weakness of his lower extremities that progressed to flaccid paralysis. Neither case was judged to have experienced additional significant trauma. Neurological complications after electrical injuries are protean. Delayed spinal cord injury is rare and associated with variable degrees of recovery. Neurological follow-up with rehabilitation is essential for a successful recovery.

Creatina fosfocinasa MB como marcador diagnóstico de disfunción miocárdica en pacientes pediátricos con quemadura eléctrica / Creatine phosphokinase MB levels as a diagnostic marker of myocardial dysfunction in pediatric patients with electrical burns

Resumen Introducción: La disminución de la fracción de eyección ventricular izquierda (FEVI) como consecuencia de una disfunción ventricular se reporta dentro de las alteraciones cardiacas secundarias a una lesión eléctrica. Como complemento de la exploración física, la ecografía cardiaca enfocada (FoCUS) permite una evaluación rápida, no invasiva, que da información para contribuir a tomar mejores decisiones terapéuticas, sobre todo en pacientes en estado crítico. El objetivo de este estudio fue explorar la utilidad de la creatina fosfocinasa MB (CPK-MB) como marcador diagnóstico de disfunción miocárdica en pacientes de 6 a 18 años con quemadura eléctrica. Métodos: Durante el periodo de noviembre de 2018 a agosto de 2019 se llevó a cabo un estudio transversal analítico de 10 pacientes, de 6 a 18 años de edad, con quemadura eléctrica, en quienes se obtuvo el porcentaje de FEVI a través del protocolo FoCUS. Posteriormente, el porcentaje de FEVI se correlacionó con los valores de CPK-MB y el porcentaje de superficie corporal quemada (SCQ) en las primeras 24 horas después de la lesión. Resultados: Se encontraron 10 casos de quemadura eléctrica, ocho de sexo masculino y dos de sexo femenino, con una media de edad de 13 años. El 80% de estos casos presentó disminución leve de la FEVI (45-59%). Al realizar el protocolo FoCUS se reportó hipocinesia miocárdica en siete pacientes. Se encontró una correlación moderada entre la FEVI y los valores de CPK-MB (r = −0.671), aunque no se observó correlación entre la FEVI y la SCQ. Conclusiones: La ecografía cardiaca influye en la toma de decisiones y mejora el pronóstico de estos pacientes.

Abstract Background: The decrease of the left ventricular ejection fraction (LVEF) as consequence of a ventricular dysfunction is reported in cardiac alterations secondary to electrical injury. The focused cardiac ultrasound (FoCUS) helps to complete the clinical examination because it allows a faster non-invasive evaluation, and provides information that contributes to make better therapeutic decisions, especially those for patients in critical condition. The objective of this study was to explore the utility of creatine phosphokinase MB (CPK-MB) as a diagnostic tool of myocardial dysfunction in patients from 6 to 18 years old with electrical burn. Methods: From November 2018 to August 2019, we conducted a transversal analytic study of 10 children with electric burn (6 to 18 years of age), in whom the percentage of LVEF was obtained through the FoCUS protocol in the first 24 hours after injury. Results: We found 10 cases of electrical burn injury, eight males and two females, with an average of 13 years of age. Eighty percent of these cases showed a slight decrease in LVEF (45-59%). When performing the FoCUS protocol, myocardial hypokinesia was reported in seven patients. We observed a moderate correlation between LVEF and CPK-MB levels (r = −0.671), and no correlation between LVEF and body surface area affected by the electrical burn. Conclusions: The cardiac ultrasound influences decision making to improve the prognosis of these patients.

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.
