Successful Management of an Occupational High-Voltage Electric Injury Associated With High-Risk Factors and a Clinically Significant Arrhythmia.

Electric injuries are uncommon but can lead to numerous long-term complications as well as death. Occupational exposure is the most common cause of injury among the affected population. Both low-voltage and high-voltage electrocution are associated with significant morbidity and mortality. Patients with certain presentations are at a high risk of arrhythmia post-injury. Here, we discuss the presentation and management of high-voltage electrocution in a 35-year-old electrician.

Capacitive coupling leading to electrical skin burn injury during laparoscopic surgery.

Purpose: Trocar-site burns occurring during laparoscopic surgery have been reported in various cases, and several efforts to reduce them are underway. This study aimed to analyze the effect of capacitive coupling on trocar site by observing electrical and histological changes for electrical skin burn injury. Methods: To measure the electrical changes relating to capacitive coupling, the temperature, current, voltage, and impedance around the trocar were measured when an open circuit and a closed circuit were formed using insulation intact instruments and repeated after insulation failure. After the experiment, the tissue around the trocar was collected, and microscopic examination was performed. Results: When open circuits were formed with the intact insulation, the impedance was significantly reduced compared to the cases of closed circuits (142.0 Ω vs. 109.3 Ω, p = 0.040). When the power was 30 W and there was insulation failure, no significant difference was measured between the open circuit and the closed circuit (147.7 Ω vs. 130.7 Ω, p = 0.103). Collagen hyalinization, nuclear fragmentation, and coagulation necrosis suggesting burns were observed in the skin biopsy at the trocar insertion site. Conclusion: This study demonstrated that even with a plastic trocar and electrosurgical instruments that have intact insulation, if an open circuit is formed, capacitive coupling increases, and trocar-site burn can occur. When using electrocautery, careful manipulation must be taken to avoid creating an open circuit to prevent capacitive coupling related to electrical skin burn.

ECG monitoring in high voltage electric injury patients presenting with normal ECG: Time to revisit practice?

Advanced Trauma Life Support (ATLS) recommends prolonged ECG monitoring of patients with high risk factors post electric injuries, for detecting and treating potentially life threatening arrhythmias. We hereby present our experience of high voltage electric injuries (HVEI) patients with high risk factors, managed at a level 1 Trauma Centre. Seven patients of high voltage electric injuries with significant burns (BSA > 10% of 2nd degree and above) were admitted over a year (Jan 1, 2019 to Dec 31, 2019), age ranging from 11 to 51 (median 25 yrs). Six out of seven patients (85.7%) were males. Mode of injury was recreational in one, workplace related in one and accidental in five (71.4%). Six patients had entry wounds in extremities, and three underwent emergency limb saving surgery (all escharotomies). Three patients underwent eventual amputation of injured extremity. Serum creatine kinase was monitored in all and multisystem involvement was seen in three patients; one patient (referred) required haemodialysis due to renal failure. There was no mortality. In all cases, 24 h continuous ECG monitoring was carried out as per ATLS and ERC (European Resuscitation Council) guidelines. There was no episode of paroxysmal or persistent rhythm disturbance in our patients during in-hospital stay or follow up. Review of pertinent literature suggests similar experiences of other authors. HVEI is a rare injury and most centres have reported on their experience with small number of patients as in our study. Currently, continuous ECG monitoring post HVEI seems to be the safe practice for patients with cardiac co-morbidities. Further studies are required to find other subsets of HVEI patients likely to benefit from ECG monitoring, and the clinical significance of 'delayed arrhythmias' post HVEI.

[Lung injury due to electric burn]. / Lesión pulmonar por trauma eléctrico.

Introduction: Electrical burns account for 3 to 4% of all burns. The most common sites of impact are the cardiovascular system, muscle tissue, neurological and skin. The commitment of the respiratory system is uncommon, with few cases reported in the literature. Case: 26-year-old male patient who enters after high-voltage electrical injury. He presented skin and respiratory distress engagement with requirement of mechanical respiratory assistance, deep sedation and neuromuscular blockade. Conclusion: There are few reported cases in the literature of lung injury associated with electrical trauma. Recognizing the respiratory system as a possible site of impact by highlighting the importance of advanced life support is critical.

Introducción: Las quemaduras eléctricas representan entre el 3 y el 4% de todas las quemaduras. Los sitios de impacto más frecuentes son el sistema cardiovascular, el tejido muscular, el neurológico y el cutáneo. El compromiso del sistema respiratorio es infrecuente, con escaso número de casos reportados en la literatura. Caso clinico: Paciente varón de 26 años que ingresa luego de lesión eléctrica de alto voltaje. Presentó compromiso cutáneo y distress respiratorio con requerimiento de asistencia respiratoria mecánica, sedación profunda y bloqueo neuromuscular. Conclusión: Hay pocos casos reportados en la literatura de lesión pulmonar asociado a trauma eléctrico. Es fundamental reconocer el sistema respiratorio como posible sitio de impacto resaltando la importancia de un soporte vital avanzado.

Just another railway fatality.

We report on a 56-year-old male who was found dead on railroad tracks, equipped with overhead high-voltage power lines (15,000 V AC). Apparently, the body had been hit by a passing train and completely severed at the mid-abdominal level. Based on this apparently unequivocal finding, the police initially assumed a fatal railway accident or suicide. However, close examination of the deceased's clothes revealed heat damage to at least four overlying layers of clothing in different locations. The rubber soles of his heavy leather shoes showed small holes in blackened areas underneath the toes. Furthermore, both socks revealed tears and fabric defects with burnt rims, again most prominent in the area of the toes. Skin burns, consistent with electric burns, and blistering were detected on the deceased's hands and feet. A broken fishing rod was found in the proximity. On autopsy, multiple injuries caused by severe blunt force with subsequent skull fracture and brain laceration as well as multiple injuries to the spinal column and rib fractures were found and visceral organs displayed multiple lacerations. However, the lack of relevant hematomas argues that these injuries were inflicted postmortem. Histological examination confirmed the presence of electric burns from electrocution. Based on the results of the forensic-pathological examination and additional investigations carried out at the scene of death, we could demonstrate that this highly unusual death was caused by an electrocution after contact of the fishing rod with the high-voltage power line and not by overrunning by the train.

Direct current electrical injuries: A systematic review of case reports and case series.

BACKGROUND: Direct current (DC) powered equipment and devices, including photovoltaic systems, high-voltage direct current power lines and novel concepts in electromobility have become increasingly popular in recent years. However, under adverse circumstances by malfunction or mishandling of these applications electrical injuries may occur when electric current passes through the human body. This review aimed at systematically summarizing the medical consequences of DC electrical injuries described in case reports and case series. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guided the methodological conduct and reporting. RESULTS: Sixteen case reports and 3 case series were eligible for this review and included 70 patients. The reviewed articles were very heterogeneous regarding sources of DC electrical injuries and the reported medical consequences, including burns and skin lesions (n=67), neurological consequences (n=11), unconsciousness (n=10), cardiac consequences (n=8) and bone fractures (n=6). Seventeen individuals did not survive the electrical injuries. CONCLUSION: From the few available data and partly incomplete documentations of cases we could gather hints of DC medical consequences, however, it was not possible to identify well-defined medical consequences for various circumstances of DC electrical injuries in occupational and non-occupational settings. To achieve this goal, additional studies are required, each providing a comprehensive description of the medical consequences and the circumstances of the electrical injuries.

Reconstrucción del cuero cabelludo después de una quemadura eléctrica de alto voltaje / Scalp Reconstruction after High-Voltage Electric Burn

Las quemaduras en el cuero cabelludo son raras. Cuando se producen suelen estar causadas por alta tensión eléctrica. La reconstrucción de los defectos del cuero cabelludo por quemaduras eléctricas se hace difícil, en parte por la extensión del defecto y la falta de determinados recursos. Se realizó una técnica con mínimo de secuelas. Se presenta un paciente masculino de 35 años, el cual llega al Cuerpo de Guardia de Caumatología por lesiones por quemaduras eléctricas de alto voltaje. Recibió el tratamiento médico quirúrgico correspondiente, injertos de piel, amputación del tercio distal del pie derecho y el 4to y 5to dedos del pie izquierdo. Solo quedó por resolver el defecto de tejido a nivel de cuero cabelludo. Se realizó rotación de un colgajo con lo cual se logró cubrir casi la totalidad del defecto, completando una pequeña zona con homoinjerto de piel. Se logró un resultado estético adecuado para el paciente con un nivel de satisfacción alto(AU)

Scalp burns are rare. When they occur, they are usually caused by high electrical voltage. The scalp reconstruction for defects caused by electrical burns is difficult, partly because of the defect area and the lack of certain resources. A technique was performed, with minimal sequelae.

Electrical Burns and Their Treatment in a Tertiary Hospital in Albania.

INTRODUCTION: The electrical current burns represent a very aggressive pathology that leaves many functional and aesthetic consequences. AIM: To evaluate the epidemiology of electrical burn injury and its associated complications and treatment. MATERIAL AND METHODS: Demographic data, aetiology, burn percentage and other measures related to electrical burn injury of 33 electrical burn patients in a tertiary hospital during the years 2015-2017. RESULTS: The mean age of patients is 31 (± 8.3) years old with a predominance of males (94%). The vast majority of injuries occurred at work (p < 0.01), superior extremities were more affected with hand (21.2%) and fingers (18.2%) being the main point of contact (p < 0.01). Muscular fasciotomy was performed in all patients who were treated surgically (n = 27), amputation was performed in 11 (40.7%) of cases, but amputated sites were more than the number of patients affected. Myoglobinuria (39.4%), cardio-respiratory distress (12.1%) contusion cerebri (6.1%), were the complication encountered in patients. CONCLUSIONS: Electrical burn injuries are still amongst the highest accident-related morbidities. Educating the population about the dangers and hazards associated with improper use of electrical devices and instruments is imperative.

Cervical Myelopathy after High-voltage Electrical Burn of the Head: Report of an Unusual Case.

High-voltage electrical injuries are uncommonly reported and may predispose to both immediate and delayed neurologic complications. We present a case of 27-year-old male who experienced a high-voltage electrical burn of the head resulting in quadriparesis. High-voltage electrocution injuries are a serious problem with potential for immediate, delayed, and long-term neurologic sequelae. The existing literature regarding effective treatment of neurologic complications is limited. Multidisciplinary management and long-term follow up are required.

Hyperkalemia in electrical burns: A retrospective study in Colombia.

INTRODUCTION: Classically, hyperkalemia has been regarded as a complication in patients with electrical burns. The etiology of hyperkalemia includes metabolic acidosis, destruction of red blood cells, rhabdomyolysis and the development of renal failure. The purpose of this study was to determine the prevalence of hyperkalemia within the first 24h after electrical burn injury and to evaluate the possible association of serum potassium concentration with cutaneous burn size (%TBSA) and serum creatine phosphokinase (CPK) concentration. METHODS: A retrospective, cross-sectional study was conducted, based on review of medical records of adult patients hospitalized in the first 24h post electrical injury. Serum potassium (K+) levels were divided into low, normal, and high groups, with breakpoints at 3.5mmol/L and 5.0mmol/L and normal 3.6-4.9mmol/L. To assess potential differences according to the time elapsed between the time of the injury and the sampling time, data were grouped as follows: t1: samples obtained in the first 6h post-injury; t2: samples taken at 6-12h; t3: samples taken at 12-24h. RESULTS: 336 patients were studied. The median age was 32 years old (IQR: 25-43). 95.2% of patients were men. Low and normal values of K+ were observed in 13.7% and 85.1%, respectively. The prevalence of hyperkalemia was only 1.2%, and was not related to previously-administered medications or to simple blood gas pH value during admission. CPK>10,000IU/L was observed in 22.6%. No association was found between the serum potassium concentration and either %TBSA burned or the highest CPK value. CONCLUSIONS: First, patients admitted to our burn unit with electrical injury accompanied by significant skin and muscle injury rarely exhibit hyperkalemia. Secondly, the presence of hyperkalemia is independent of the severity of rhabdomyolysis or the extent of the burn.

Acute Rotator Cuff Tears due to Low Voltage Electrical Injury: A Case Report.

Since shoulder have a higher proportion of muscle which would have low electrical resistance, there could be more electrical damage to the rotator cuff muscles. We present a patient with acute rotator cuff tear by sudden uncontrolled jerking contractions caused by an electrical shock. A case of 42-year-old man with acute rotator cuff tear due to electrical injury to the shoulder was presented. Magnetic resonance imaging showed a full thickness tear and an undulating appearance of the peripheral end of the torn supraspinatus and infraspinatus muscle, suggesting an acute complete rupture. By arthroscopic surgery, the torn rotator cuff tendons were repaired with a suture bridge technique. At the final follow-up, the patient had a full, pain-free range of motion and had fully recovered shoulder muscle power.

Síndrome compartimental agudo en quemadura eléctrica / Acute compartment syndrome in electric burn

Introducción: El síndrome compartimental agudo es el aumento anormal de la presión en los compartimentos musculares en las primeras horas posteriores a la lesión, generando isquemia, necrosis e, incluso, la muerte de la extremidad afectada. Su tratamiento consiste en la rápida descompresión quirúrgica, con lo cual se preserva la vitalidad de los tejidos. El síndrome compartimental es una entidad poco frecuente en la práctica clínica, y el tratamiento depende de su sospecha y pronto diagnóstico. Métodos: Reportamos el caso clínico de un adulto medio con quemadura eléctrica en miembros superiores, quien durante estancia hospitalaria presentó síndrome compartimental, se realizó el diagnóstico oportuno y fue llevado a fasciotomía temprana con adecuada evolución. Este manuscrito tiene como objetivo realizar una revisión de la literatura e informar al lector sobre los aspectos fundamentales para la sospecha de esta patología. Resultados: Dentro de las características de este síndrome se incluye la disminución de la perfusión tisular, con compresión mecánica del flujo vascular por aumento del contenido en el compartimento y por disminución del continente. El principal síntoma es dolor exagerado con respecto a la lesión, asociado a parestesias, palidez y frialdad. Conclusiones: Además de la limitación en la movilidad de los dedos y la mano, el síntoma principal del síndrome compartimental es el dolor. Un dolor excesivo debe alertarnos siempre y hacernos sospechar un síndrome compartimental. Además, el dolor causado por el estiramiento pasivo de los músculos es un hallazgo clínico más sensible en un síndrome compartimental en desarrollo.(AU)

Introduction Acute compartment syndrome is the abnormal increase of pressure in the muscular compartments in the first hours after the injury, generating ischemia, necrosis and even the death of the affected limb. Its treatment consists in the rapid surgical decompression with which the vitality of the tissues is preserved. The compartment syndrome is a rare entity in clinical practice and its treatment depends on its suspicion and early diagnosis. Methods We report the clinical case of an adult with electrical burn in the upper limbs, who during the hospital stay presented compartment syndrome, was made the opportune diagnosis and was taken to early fasciotomy with adequate evolution. This manuscript aims to conduct a review of the literature and inform the reader about the fundamental aspects for the suspicion of this pathology. Results Among the characteristics of this syndrome is the decrease in tissue perfusion, with mechanical compression of the vascular flow due to an increase in the content of the compartment and a decrease in the continent. The main symptom is exaggerated pain with respect to the injury, associated with paresthesias, pallor and coldness. Conclusions In addition to the limitation in the mobility of the fingers and the hand, the main symptom of compartment syndrome is pain. Excessive pain should always alert us and make us suspect a compartment syndrome. In addition, the pain caused by passive stretching of the muscles is a more sensitive clinical finding in a developing compartment syndrome.(AU)

Electrical burns in times of economic crisis: A new epidemiologic profile.

Electrical injuries and especially those of high voltage still remain a source of high morbidity. Over the past few years, a change in the epidemiologic profile of these lesions was noticed at the Vall d'Hebron University Hospital Burn Unit, corresponding to an increase in cases out of the legal framework. It is our aim to describe this particular subset, to determine the extent of their injuries and to understand the reason for their increased incidence. We think this was favoured by the rise in the unemployment rate, along with higher copper prices.

Pattern and profile of electric burn injury cases at a Burn centre.

BACKGROUND: Electrical burns are quite different from thermal and chemical burns. This study is from a centre which deals with job related electric burn injuries alone and thus can give a pure account of the electric burns and discuss the related peculiarities. Study aims to highlight the differences in the mechanism of electric burn injury, its mode of presentation, morbidity, complications and thus the treatment strategies as compared to rest of the burn injuries. METHODS: This is a descriptive case series study of first consecutive 61 electric burn victims treated at a Burn Unit and Plastic Surgery centre. Cases were admitted and resuscitated at the emergency, and further treated at burn unit. Thorough history, examination findings and operative procedures were recorded. Patients were photographed for record as well. Emergency operative procedures, wound management, soft tissue coverage procedures and complications during the hospital stay were recorded and studied. RESULTS: Twenty cases (33%) were in the fifth decade of life. High voltage electric burn injury was seen in 42 (69%) of the cases. Whereas only 9 cases were treated conservatively, other 52 cases had 24 fasciotomies and 71 debridements. Series witnessed 10 expiries, and 22 amputations and all these were result of high voltage electric burns. Twenty eight soft tissue coverage procedures were carried out. CONCLUSIONS: Electric burn injuries are altogether different from rest of the burn injuries and must be treated accordingly. These injuries are peculiar for ongoing damage, extensive trauma, complications and prolonged morbidity. Treatment requires a high degree of suspicion, more aggressive management to unfold and minimize the deep seated insult.

Serum Prealbumin Affected More by Serum CRP Than by Residual Burned Surface Area

PURPOSE: Prealbumin is known as a biochemical marker for assessing nutritional status, and it is influenced by a systemic inflammatory condition. This study aims to find any correlation between patients' low serum prealbumin in electrical burn and unhealed burn surface area and insufficient nutritional support. METHODS: Data were collected by a review of the medical charts of patients admitted to Hanil General Hospital for electrical burn. Laboratory results such as prealbumin, albumin, total lymphocyte count (TLC), and C-reactive protein (CRP) were collected and tested every week. Residual burn surface area (residual BSA) during a specific period was calculated from the surgery record. Statistical analysis was conducted using Pearson's correlation and multiple regression analysis. RESULTS: A total of 30 subjects were selected, all male. Average total burn surface area was 20.9±14.9%, and patients were operated on about three times after admission. There was statistical significance among all variables in Pearson's correlation test, but in multiple regression analysis, albumin and CRP were significant compared with prealbumin. CONCLUSION: The results could indicate that burn causes a systemic inflammatory reaction, which could affect the serum prealbumin level. Further study concerning the biological plausibility of each variable is needed.

Fisiopatología, manifestaciones sistémicas y secuelas de la fulguración en seres humanos / Pathophysiology systemic manifestations and sequelae of electrocution in humans

Un rayo es un impulso masivo de corriente unidireccional creado por un gradiente de electrones entre dos nubes o una nube y la tierra. El trauma eléctrico por lo general no es mortal, sin embargo se asocia a una serie de complicaciones médicas de importancia. Las secuelas están determinadas tanto por la intensidad de la corriente como por la duración de la aplicación energética. Las lesiones por electrofulguración ocurren por distintos mecanismos: golpe directo, lesión de contacto, “side splash”, corriente por tierra y trauma contuso. La electricidad atmosférica causa diferentes tipos de lesiones a nivel de la piel, como es el caso de las quemaduras lineales, punteadas, térmicas y en plumaje. Las figuras de Lichtenberg son patognomónicas de la electrofulguración. Además del efecto sobre el sistema tegumentario, se documentan lesiones cardiovasculares, respiratorias, gastrointestinales, oculares, auditivas y neurológicas. Cuando se presenta una muerte por electrofulguración, como pocas veces es presenciada y ocurre en espacios abiertos, se debe realizar un estudio exhaustivo del cadáver y del lugar del suceso para descartar otras causas de muerte natural o violenta. En Costa Rica en el año 2011 se presentaron 7 muertes por electrofulguración, principalmente durante la juventud y adultez temprana y a nivel de la zona rural, siendo el principal mecanismo de lesión el golpe directo.

Lightning is a massive unidirectional current that depends of an electron gradient; this electric flow travels from one cloud to another or to the ground. Electric trauma generally is not lethal, however, it is associated to several complications. Sequelae are determined both by the current strength and by the duration of the exposure. Lightning damage occurs by different mechanisms: direct strike, contact injury, side splash, ground current, and blunt trauma. Atmospheric electricity causes different skin lesions such as linear, punctate, thermal, and plumage burns. Lichtenberg figures are pathognomonic for lightning. Besides the effect on the integumentary system, respiratory, gastrointestinal, ocular, auditory, cardiovascular, and neurological injuries are documented as well. When lightning causes death, it usually happens in open places without witnesses. An exhaustive study of the cadaver and the setting of the event should be accomplished in order to exclude natural or violent causes of death. In Costa Rica in 2011, there were seven deaths related to lightning; young adults predominated and most took place in rural areas, being direct strike the main mechanism of damage.

Electrical burn injury: a five-year survey of 682 patients.

BACKGROUND: Electrical burn is less prevalent in comparison to other forms of burn injuries, however this type of injury is considered as one of the most devastating due to high morbidity and mortality. Understanding the epidemiologic pattern of electrical burns helps determine the contributing factors leading to this type of injury. OBJECTIVES: Epidemiologic studies on electrical burn are scarce in Iran. This study was conducted to evaluate electrical burn injury at our center. MATERIALS AND METHODS: Demographic data, etiology, burn percentage and other measures related to electrical burn injury of 682 electrical burn patients treated from 2007 to 2011 were collected and analyzed. RESULTS: We assessed 682 electrical burn patients (~10.8% of all burn patients); the mean age was 29.4 years and 97.8% were males. The mean hospital stay was 18.5 days and the mean burn extent was 14.43%. Severe morbidities caused 17 (2.5%) deaths. Amputation was performed in 162 cases. The most common amputation site was the fingers (35%). Most victims were workers and employees and 68.5% of electrical burns occurred at their workplace; 72% of electrical burns were due to high voltage electrical current (more than 1000 V). There was a correlation between voltage and amputation (P = 0.001) and also between voltage and fasciotomy (P = 0.033), but there was no correlation between voltage and mortality (P = 0.131). CONCLUSIONS: Electrical burn injuries are still amongst the highest accident-related morbidities and mortalities. Educating the population about the dangers and hazards associated with improper use of electrical devices and instruments is imperative.

Descriptive Study of Occupational Accidents and their Causes among Electricity Distribution Company Workers at an Eight-year Period in Iran.

BACKGROUND: Occupational accidents are unplanned events that cause damage. The socio-economic impacts and human costs of accidents are tremendous around the world. Many fatalities happen every year in workplaces such as electricity distribution companies. Some electrical injuries are electrocution, electric shock, and burns. This study was conducted in an electricity distribution company (with rotational 12-hour shift work) in Iran during an 8-year period to survey descriptive factors of injuries. METHODS: Variables collected included accident time, age of injured worker, employment type, work experience, injury cause, educational background, and other information about accidents. RESULTS: Results indicated that most of the accidents occurred in summer, and 51.3% were during shift work. Worker negligence (malpractice) was the cause of 75% of deaths. Type of employment had a significant relationship with type of injuries (p < 0.05). Most injuries were electrical burns. CONCLUSION: High rate of accidents in summer may be due to the warm weather or insufficient professional skills in seasonal workers. Shift workers are at risk of sleep complaints leading to a high rate of work injuries. Acquiring knowledge about safety was related to job experiences. Temporary workers have no chance to work all year like permanent workers, therefore impressive experiences may be less in them. Because the lack of protective equipment and negligence are main causes of accidents, periodical inspections in workshops are necessary.
