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.

Institutional Experience Using a Treatment Algorithm for Electrical Injury.

Electrical injury has low incidence but is associated with high morbidity and mortality. Variability in diagnosis and management among clinicians can lead to unnecessary testing. This study examines the utility of an electrical injury treatment algorithm by comparing the incidence of testing done on a cohort of patients before and after implementation. Demographics, injury characteristics, and treatment information were collected for patients arriving to a regional burn center with the diagnosis of electrical injury from January 2013 to September 2018. Results were compared for patients admitted before and after the implementation of an electrical injury treatment algorithm in July 2015. There were 56 patients in the pre-algorithm cohort and 38 in the post-algorithm cohort who were of similar demographics. The proportion of creatine kinase (82% vs 47%, P < .0006), troponin (79% vs 34%, P < .0001), and urinary myoglobin (80% vs 45%, P < .0007) testing in the pre-algorithm cohort was significantly higher compared to post-algorithm cohort. There were more days of telemetry monitoring (median [IQR], 1 [1-5] vs 1 [1-1] days, P = .009) and greater ICU length of stays (4 [1-5] vs 1 [1-1] days, P = .009), prior to algorithm implementation. There were no significant differences in total hospital lengths of stay, incidence of ICU admissions, in-hospital mortality, or 30-day readmissions. This study demonstrates an electrical injury evaluation and treatment algorithm suggests a mode of triage to cardiac monitoring and hospital admission where necessary. Use of this algorithm allowed for reduction in testing and health care costs without increasing mortality or readmission rates.

Risk Factors for Mortality and Prolonged Hospitalization in Electric Burn Injuries.

Electrical injuries are rare, but very destructive with high morbidity and mortality, prolonged hospital length of stay and need for repeated procedures. The aim of study was to investigate characteristics and management of electrical injuries and predisposing factors for mortality and prolonged length of stay. Patient charts were reviewed retrospectively to identify patients admitted with electrical injuries at the Zurich Burns Center (2005-2019). Patient characteristics, management, and outcome were analyzed and risk factors for mortality and prolonged hospitalization were assessed. Eighty-nine patients were included, mostly males (86.5%), between 21 and 40 years (50.6%), with high-voltage (74.2%) occupational injuries (66.3%). Median intensive care unit and hospital stays were 6 (first and third IQR: 2.0; 30.0) and 18 (9.0; 48.0) days. Low-voltage patients had a median of 2 (1.5; 3.0) procedures, compared to 4 (2.0; 10.8) in high-voltage. The amputation rate was 13.5%, and a total of 46 flaps were required. Fifty-four patients had at least one serious complication. Mortality was 18% in high-voltage patients, mostly after multiple organ failure (35%). High total body surface area (TBSA), renal failure and cardiovascular complications were risk factors for mortality (P < .001) in multivariate regression models. Determinants for prolonged hospital stay were TBSA and sepsis (P < .01), and additionally abdominal complications and limb loss for intensive care unit stay (P < .05). Electrical injuries are still cause of significant morbidity and mortality, mostly involve young men in their earning period. Several risk factors for in-hospital mortality and prolonged stay were identified and can support physicians in the management and decision making in these patients.

Lesions and characteristic injury patterns caused by high-voltage fault arcs.

Exposure to high-voltage electric arcs as a result of an accident or by means to commit suicide can affect people's health and cause death. There are characteristic external findings that can be found on external examination. These include extensive skin burns, periorbital recesses or "crow's feet," vapor deposition of conductor material, known as metallization, and tightly spaced, roundish, crocodile skin like burns. The Institute of Legal Medicine of the Rostock University Medical Center recorded 16 deaths caused by exposure to electricity between 1990 and 2018. Six of these deaths were caused by exposure to high-voltage electric arcs and five of these deaths (83 %) showed crocodile skin like burns and one had periorbital recesses burns on the face as a result of a fault arc. To our knowledge, the present paper is the first report describing the frequent occurrence of crocodile skin like burns due to high-voltage fault arcs.

Microbiology and Infection Profile of Electric Burned Patients in a Referral Burn Hospital in Mexico City.

Electrical burn injuries are one of the most severe forms of trauma. This study aims to investigate the infection complications in electrical burn patients in a referral hospital in Mexico City. A longitudinal retrospective study was conducted, involving electrical burn patients admitted from April 2011 to December 2016. Demographic and clinical data including type of electric burns, infection complications, and mortality was sought. Data were collected at admission and daily until discharge. Number and type of infections and microorganism isolations were sought. Risk factors for death were analyzed. A total of 111 patients were included, of which 96.4% were males, mean age of 31.6±16.22, most injuries were high voltage associated. The total body surface area average was 27.8% ± 19.63. The overall infection rate was 72.9 cases per 100 patients. Mortality was observed in 4 (3.6%) patients. About 59.1% (443/749) had growth for Gram-negative bacteria. Multidrug-resistant Pseudomonas aeruginosa was the most frequent microorganism isolated. Fungi were present in 4.9% of cases. Electrical burn injuries occurred in young males in our study. Infection was frequent, most of them caused by Gram-negative rods with an important rate of antimicrobial resistance; however, an important microbial diversity was present.

Alarming rise in fatal electrocutions in Bangladesh: Comparison of two national surveys.

BACKGROUND AND OBJECTIVES: Electrical injuries are major contributor to burn-related mortality and morbidity. Mortality data were compared from the two largest community-based health and injury surveys in Bangladesh conducted thirteen years apart to investigate the changes in epidemiological features of this adverse health event. METHODS: The nationwide Bangladesh Health and injury surveys (BHIS) were conducted among 819,429 people in 2003 and 299,216 in 2016 using a pretested semi-structured questionnaire at the household level. History of electrocution death events in previous one year in the household was determined by verbal autopsy method in both surveys. Thus, each survey result represents the scenario of the year before. Descriptive and comparative analysis was done to investigate the changes in the distribution of electrocution deaths. RESULTS: The incidence of electrocution deaths was 1.7 and 4.3 per 100,000 population respectively in the 2003 and 2016 survey. The majority of the cases were aged between 18 to 59 years in both years. The comparison of the two survey results shows that the death rates increased in every age group those were examined. The rates were persistently higher in rural areas compared to the urban. Moreover, the rural mortality rate increased strikingly in 2015. The highest proportion of fatal electrocution events occurred at workplaces and males had a higher mortality rate in contrast to females in both the surveys. The death rate in males doubled in 2015 (6.0 per 100,000) from 2002 rate (3.1 per 100,000). CONCLUSION: Electrocution mortality rates have raisen alarmingly between 2002 and 2015. Working persons and males have a higher susceptibility to deaths from electrocution. Rural areas pose greater threats compared to urban Bangladesh. Being derived from a nationwide survey, these facts provide with useful direction to set priorities for prevention of this emerging unnatural cause of death in the country.

A Histologic Perspective on Electrical and Thermal Burn-Injured Human Skin.

OBJECTIVE: To analyze specific spectroscopic (FT-Raman) and thermal (limiting oxygen index) aspects of skin samples exposed to electrical injury compared with thermal injury. METHODS: An observational case-control study was conducted at the Dr Stanislaw Sakiel Center for Burns Treatment in Siemianowice, Silesia, Poland. A scanning electron microscope was used to diagnose and illustrate the topography of skin samples from electrical and thermal burns and the morphologic effects on damaged versus undamaged skin surfaces. In particular, researchers attempted to detect spectroscopic and thermal changes at the molecular level, namely, specific biomarkers of tissue degeneration and their regeneration under the influence of the applied modifiers (antioxidants and orthosilicic acid solutions). RESULTS: Modification with L-ascorbic acid and hydrogel of orthosilicic acid caused an increase in the intensity of the amide I Raman peaks, whereas modification with sodium ascorbate and orthosilicic acid resulted in the separation of the band protein side chains (1,440-1,448 cm), which is a part of tissue regeneration. The best result was obtained when the skin was treated with 7% orthosilicic acid (limiting oxygen index, 26%). CONCLUSIONS: Antioxidant treatment may be advantageous in minimizing injury in patients with thermal burns but not always in electrical burns.

Epidemiology and outcomes of burn injuries at a tertiary burn care center in Bangladesh.

Globally, burns are among some of the most devastating injuries and account for more than 265,000 deaths worldwide. In Bangladesh alone, nearly 3000 people die annually from burn-related injuries. This study was conducted at the National Institute of Burn and Plastic Surgery in Dhaka, Bangladesh in June of 2016. Data included conducting surveys of hospitalized burn patients (N=66) and a chart review of deceased burn patients (N=88). In addition to reporting on the demographic profile of patients, information was also obtained on clinical measures during hospitalization. For non-fatal burns, high risk groups included young adult males (early 30s) of lower socioeconomic status. Among children, the most vulnerable group was found to be children less than eight years old. The most common non-fatal types of burn injuries were flame (35%), electrical (31%) and scald (24%). Discharged patients had an average hospital stay of around 30days with half of all patients requiring surgical intervention, thus indicating the severity of those cases and the need for resource-intensive care. Among the discharged patient population, factors significantly associated with a longer duration of hospital stay included severity of injury, not having received prior treatment before admission and whether or not patients required surgery during hospitalization. Among the mortality cases, the high-risk groups also included young adult males and children of around eight years of age. The average total body surface area (TBSA) sustained in these cases was 46.4%, with 65% of deaths attributable to complications from flame burns. These findings highlight the frequency and severity of burn injuries, identify vulnerable population groups and list common causes of burns in this large developing country of 160 million people. Furthermore, these findings may be applicable to the epidemiology and outcome of burns in similar low and middle income countries.

Changes in burn mortality in Bangladesh: Findings from Bangladesh Health and Injury Survey (BHIS) 2003 and 2016.

PURPOSE: This paper is focused to reflect the changes in burn mortality and events leading to fatal burn injuries. METHODS: Two national community-based cross sectional health and injury surveys were done in Bangladesh during 2003 and 2016. Similar methodology had been followed in both the surveys. Multistage cluster sampling method considering probability-proportional-to-size strategy was used in both the surveys to obtain the desired sample. A pretested semi-structured questionnaire was deployed to identify causes of mortality and morbidity among the population. Verbal autopsy method was used to ascertain the cause of death. RESULTS: An estimated 5000 deaths occurred during 2002 due to burn, whereas, around 9000 deaths were caused by burn in 2015 reflected by the death rates 3.5 and 5.7 per 100,000 population in respective years. This study found an increase in death rates in all age groups from 2002 to 2015. Electrocution caused the highest burn deaths in this country, especially among males and in rural areas. The death toll by this particular mechanism has increased by more than two folds within a decade. The place of occurrence of fatal burn injuries has also shifted from home to the outside of the home especially in the agricultural fields. CONCLUSION: Burn death is an emerging cause of injury deaths in Bangladesh. Further researches are required to explore the epidemiology of electrocution deaths in Bangladesh and design effective interventions.

Factors affecting mortality among victims of electrical burns.

BACKGROUND: The aim of this study was to determine the factors affecting mortality rate among patients with an electrical burn. METHODS: A total of 115 patients admitted to the emergency department and hospitalized in the Burn Treatment Center or Intensive Care Unit (ICU) due to the electrical burn, were included in the study. RESULTS: A total of 115 patients (4 female and 111 male) with a mean age of 32.88±12.87 years were included in the study. The mean hospitalization period was 25.03±20.50 days, and the mean total body surface area burned (% TBSA) was 22.83±15.54%. Among those patients, 9 (8.5%) expired, and the remaining 106 were discharged after treatment. In a logistic regression analysis, TBSA >20% (p=0.02, OR: 11.7, CI: 1.38-99.16); ICU requirement (p=0.005, OR: 1.28, CI: 1.08-1.58); erythrocyte transfusion requirement (p=0.02, OR: 12.48, CI: 1.44-107.83); fresh frozen plasma (FFP) requirement (p=0.03, OR: 10.23, CI: 1.18-88.17); albumin requirement (p=0.02, OR: 12.60, CI: 1.44-109.85); admission serum albumin level <3.5 mg/dl (p=0.04, OR: 7.25, CI: 0.82-63.64); and admission hemoglobin level <12 mg/dl (p=0.01, OR: 8.29, CI: 1.57-43.61) were determined as risk factors for mortality in patients with electrical burns. CONCLUSION: In clinical practice, defining a mortality risk analyzer using these factors may be helpful in the management of patients with electrical burns. Additional, more comprehensive studies are required to define the risk factors for mortality and long-term morbidities in patients with electrical burns.

Clinical spectrum of electrical burns - A prospective study from the developing world.

INTRODUCTION: Electrical burns are devastating, posing development of multiple injuries with high morbidity and mortality. Electrical burn management benefits from a multidisciplinary, multispecialty collaborative approach to improve outcomes. OBJECTIVE: To highlight the clinical spectrum of electrical burns in the developing world, including common etiologies, presentation, intervention, associated injuries, and complications. MATERIALS AND METHODS: A prospective study was conducted from January 2010 to December 2015 that included 78 patients (75 men and 3 women), who presented with a history of electrical burns. Patients were interviewed for detailed clinical history and physical examination. RESULTS: The study comprised 78 patients (high-voltage group: 38.46% and low-voltage group: 61.54%). The most affected age group was the 21-40 year age group. High-voltage injuries were more devastating. The most common complication was septicemia in 24.4% of the patients, which included 43.3% from the high-voltage group. CONCLUSION: Electrical burns affecting young adult men can impose a significant burden in developing countries. Electrical burns, especially due to high voltage, involve multiple organs benefitting from multidisciplinary management and have significant residual sequelae. Public awareness and education and proper training of industry workers remain the best way to minimize the prevalence of electric burns in the developing world.

Comparison of the Results of Early Flap Coverage with Late Flap Coverage in High-Voltage Electrical Injury.

Patients with high-voltage electrical injuries had very high rates of infection, morbidity, and limb amputation. The results of early and late flap coverage in these patients were prospectively compared. The patients were divided into two groups, early flap group (≤3 weeks) and late flap group (>3 weeks), according to the length of time from injury to wound coverage with flap. Age, sex, demographic data, time taken for flap coverage, time taken for pedicle division, time taken to discharge, wound infection, range of motion in joints, amputation, mortality, and outcome were gathered in a special questionnaire. This study included 55 patients, 31 within the early flap group and 24 within the late flap group. Of the 55 patients, 94.6% were male; mean (SD) of age was 29.04 (10.11) and of TBSA was 13.8 (10.07). Length of stay was significantly longer in the late flap group. The rates of infection and amputation were lower in the early flap group. There was no correlation between the type and the number of flaps and amputations. Early flap repair reduces the length of stay by 56%, rate of amputation by 54%, and also 86.1% in the rate of infection in the burn site.

Review of Adult Electrical Burn Injury Outcomes Worldwide: An Analysis of Low-Voltage vs High-Voltage Electrical Injury.

The aims of this article are to review low-voltage vs high-voltage electrical burn complications in adults and to identify novel areas that are not recognized to improve outcomes. An extensive literature search on electrical burn injuries was performed using OVID MEDLINE, PubMed, and EMBASE databases from 1946 to 2015. Studies relating to outcomes of electrical injury in the adult population (≥18 years of age) were included in the study. Forty-one single-institution publications with a total of 5485 electrical injury patients were identified and included in the present study. Fourty-four percent of these patients were low-voltage injuries (LVIs), 38.3% high-voltage injuries (HVIs), and 43.7% with voltage not otherwise specified. Forty-four percentage of studies did not characterize outcomes according to LHIs vs HVIs. Reported outcomes include surgical, medical, posttraumatic, and others (long-term/psychological/rehabilitative), all of which report greater incidence rates in HVI than in LVI. Only two studies report on psychological outcomes such as posttraumatic stress disorder. Mortality rates from electrical injuries are 2.6% in LVI, 5.2% in HVI, and 3.7% in not otherwise specified. Coroner's reports revealed a ratio of 2.4:1 for deaths caused by LVI compared with HVI. HVIs lead to greater morbidity and mortality than LVIs. However, the results of the coroner's reports suggest that immediate mortality from LVI may be underestimated. Furthermore, on the basis of this analysis, we conclude that the majority of studies report electrical injury outcomes; however, the majority of them do not analyze complications by low vs high voltage and often lack long-term psychological and rehabilitation outcomes after electrical injury indicating that a variety of central aspects are not being evaluated or assessed.

Burns in Israel, comparative study: Demographic, etiologic and clinical trends 1997-2003 vs. 2004-2010.

OBJECTIVES: To review hospitalised burn patients from 2004 to 2010 admitted to Israeli burn units and compare these result with data from 1997 to 2003. METHODS: Retrospectively, data was collected from the Israeli Trauma Registry (ITR) encompassing all burn admissions to Israeli burn units from 2004-2010 and compared to 1997-2003. RESULTS: Of the 5269 burn patients admitted from 2004 to 2010, 39.8% were non-Jewish. Infants under two years were the prominent age group (24.1%). Second to third degree burns 1-9% TBSA/first degree burns were 71%, second to third degree burns 10-19% TBSA were 16% and those 20%>TBSA consisted of 13%. Only 2.7% involved an inhalation injury. The average length of stay was 11.67 days and mortality rate 3.72%. All data was compared to the previous year's 1997-2003 and trends were identified. CONCLUSIONS: Within Israel, high risk populations remain infants under two years of age, males and those from non-Jewish populations. National prevention strategies and campaigns are warranted to inform and educated parents of young children and those at risk of burns. Of note, advances in burn care and procedures might have contributed to a decrease in the length of hospital stay (LOS).

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.

Effect of current pathway on mortality and morbidity in electrical burn patients.

INTRODUCTION: Electrical injury is relatively uncommon but it is a devastating form of thermal injury. The aim of this study is to analyze specific aspects of electrical injuries, especially the effect of current pathways on morbidity and mortality. METHOD: This descriptive-analytical study was performed on patients with electrical burns who were admitted to the Shahid Motahary Burn Center from April 2010 to March 2012. Demographic and clinical data including gender, age, length of hospital stay, total body surface area (TBSA), grading of burn, electrical voltage, inlet electrical mark, outflow electrical mark, current pathway, surgical procedures, and place of electrical burn have been gathered from medical records. The site of inlet and outlet of current on the body is divided into six groups: Rt (right) upper limb, Lt (left) upper limb, Rt lower limb, Lt lower limb, head and neck, and trunk. According to these sites, the current pathway is defined to seven groups. Data were analyzed with SPSS software, version 20. RESULTS: From 287 patients, 283 were men and 4 were women. The mean age was 30±12 years (range 1-71) and mean TBSA was 13.56±12.97% (range 1-100). There were 233 patients (81.2%) with passage of the electrical current through the body and 54 patients (18.8%) with flash burns. A total of 859 surgical procedures were performed on 232 patients. One hundred and eighteen amputations were performed in 83 patients. The most common inlet electrical marks were in Rt upper limb and the most common outlet electrical marks were in Lt lower limbs, and consequently, the most common pathway was upper limb to lower limb. CONCLUSIONS: Electrical injuries are mainly occupation-related injuries and in this research majority of injuries occurred outdoor by high voltage cables in young men. Thus the government should consider a distinct strategy for this group. Also it is observed that there were no significant differences in mortality and complications such as amputation between different pathways.

A population-based study of the epidemiology of acute adult burns in Ecuador from 2005 to 2014.

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.

Prognostic factors in electrical burns: a review of 101 patients.

PURPOSE: Electrical burn wounds are among the most devastating of burns, with wide-ranging injuries. We aimed to document the factors affecting the mortality rate of patients presenting with electrical burn wounds to our regional burn centre. METHODS: This retrospective study was conducted on 101 patients from January 2009 to June 2012. Factors were classified under 11 topics and evaluated according to their relationship with the mortality rate. RESULTS: The major causes of death in burn victims were multiple organ failure and infection. Twenty-six percent of the 101 patients died, all of whom were male. One (1.4%) of the patients who survived was female; 73 (98.6%) survivors were male. The mean age in the deceased group was statistically higher than that of the other patients (32.7 vs. 35.6 years; P < 0.05). All-cause mortality was 2.79 times higher for larger burns (> 25% total body surface area). The values for creatine kinase, creatine kinase-MB, total body surface area of burn, hospitalised period in the intensive care unit and intubation rate were significantly higher in the exitus group. Renal injury requiring haemofiltration was associated with an almost 12-fold increased risk for mortality. There was no statistically significant difference between patients regarding surgical interventions. CONCLUSION: Electrical injury remains a major cause of mortality and long-term disability among young people. Our data demonstrated several risk factors associated with increased mortality rate in patients with electrical burn wounds.
