RESUMO
BACKGROUND: This study aimed to assess the clinical epidemiological characteristics of children with electrical injuries and discuss the countermeasures for the prevention of electrical injuries in children. METHODS: The children with electrical injuries were grouped according to whether or not they were admitted to the hospital for treatment into inpatient and outpatient groups. Clinical data such as gender, causes of injury and injury-causing voltage distribution in different age groups were analyzed. The factors affecting hospitalization were subjected to χ2 test, Kruskal-Wallis H test, and logistic regression analysis. RESULTS: A total of 321 children were included with 37 divided into inpatient group and 284 divided into outpatient group. The incidence of electrical injuries was highest in children ≤6 years old and in the summer. There were significantly different in gender, place of occurrence, cause of injury and injury-causing voltage between the two groups (p < 0.05). Injury-causing voltage is an independent risk factor affecting hospitalization of children with electrical injuries (OR = 0.116, 95 %CI = 0.040-0.334, p = 0.000). In children ≤6 years old, boys suffered electrical injuries more frequently than girls; battery powered vehicle (47.53 %) was primarily the cause of injury; most of the patients (64.64 %) were exposed to low voltage below 100 Vs, mainly in the case of adolescent children. CONCLUSION: Male preschoolers accounted for the majority of electrical injury cases, and these accidents mostly happened in household electrical appliances and household battery cars. Overall, it is necessary to improve family electrical safety education and reinforce protective measures against electric injury to children.

INTRODUCTION: Electrical injuries can be devastating, and data is lacking in low-resource settings. We aimed to identify predictors of mortality following electrical and lightning injuries (ELI) in Malawi. METHODS: We performed a retrospective observational study of patients presenting with ELI and burn injuries at a tertiary hospital in Malawi from 2011 to 2020. Outcomes were compared and predictors of mortality were modeled. RESULTS: A total of 382 ELI and 6371 burn patients were included. The mean ages for ELI and burn groups were 24 ± 14 and 11 ± 14 years, respectively (p < 0.01). Most patients were injured at home (91% in the burn group versus 51% in the ELI group, p < 0.01). The crude mortality rate in the ELI group was 28%, compared to 12% in the burn group (p < 0.01). On multivariate logistic regression, predictors of mortality included ELI (odds ratio [OR] 13.3, 95% confidence interval [CI] 7.2-24.5) and total body surface area burned (OR 1.1, 95% CI 1.1-1.1). Predicted mortality for ELI has increased over time (p = 0.05). CONCLUSIONS: ELI confers more than 13 times higher odds of mortality than burn injuries in Malawi, with mortality risk increasing over time. More efforts are needed to prevent electrical hazards and implement timely interventions for patients with ELI.

BACKGROUND: Even though electrical injuries are common in the emergency room, guidelines, consensus, and general recommendations for the management of these patients do not exist in Europe. Documented cases of delayed arrhythmias are rare and their connection with electrical injury has not been fully confirmed. We also use cardio-specific markers for the risk stratification of myocardial injury, but there is no significant study referring to their utility in this clinical situation. These reasons led us to retrospectively analyze all cases of electrical injuries over 23 years to determine the prevalence of cardiac arrhythmias (mainly malignant arrhythmias and delayed arrhythmias). METHODS: We retrospectively searched all patients admitted to the University Hospital in Pilsen, CZ, with a diagnosis of electric injury (ICD diagnostic code T754) from 1997 to 2020. The hospital´s information system was used to research the injury; data were drawn from patient medical records. RESULTS: We identified 333 cases of electrical injury in our hospital. Men accounted for about two-thirds, and women one-third. Children accounted for about one-third of cases. Most were low-voltage injuries (< 1000 V, 91.6%). All participants had an initial ECG, and 77.5% of patients had continuous ECG monitoring, usually lasting 24 h. Cardiac arrhythmias were noticed in 39 patients (11.7%). The most frequent arrhythmias were: ventricular fibrillation, sinus tachycardia, bradycardia and arrhythmia, atrial fibrillation, and supraventricular tachycardia. The ECG showed cardiac conduction abnormalities in 28 patients (8.1%), and ten patients (3%) had supraventricular or ventricular extrasystoles. In ten cases (3%), we found changes in ST segments and T waves on the initial ECG. Thirty-one patients (9.3%) suffered a loss of consciousness and 50 patients (15.02%) reported paresthesia. The most frequent ion disbalances were hypokalemia (18%) and hypocalcemia (3.3%). Patients with an ion disbalance had significantly more arrhythmias and newly diagnosed cardiac conduction abnormalities. Troponin levels (cTnI or hs-cTnT) were measured in 258 cases (77.48%) and found to be elevated above the 99th percentile in 19 cases (5.7%). Almost one-third of patients had burns of various degrees of seriousness, and 41 patients (12.3%) had concomitant traumatic injuries. Eleven patients underwent pre-hospital resuscitation, three died in the hospital, and another died as result of intracranial hemorrhage. CONCLUSION: All malignant arrhythmias occurred immediately after the electrical injury, delayed life-threatening arrhythmias were not observed, and no predictive factors of malignant arrhythmias were found. While elevations of cardiac troponins were observed sporadically, they did not appear helpful for risk stratification. In patients with arrhythmias, ion disbalance may be more critical. We concluded that asymptomatic, uninjured adult and pediatric patients with normal initial ECG findings do not need continuous ECG monitoring and may be discharged home. Recommendations for high-risk patients and patients with mild ECG abnormalities at admission are less obvious.

Aim of this study is to research the fatal electrical injury rate in the Russian Federation, identified during the forensic medical investigation/examination of corpses for the period of 2003 to 2021, and to detect Russian regions, where fatal electrical injury rates are significantly higher than the national average. Based on research of annual reports, it has been established, that the fatal electrical injury reaches insignificant, but relatively stable part in the total amount of violent death and fatal mechanical injury in the Russian Federation. The analysis of fatal electrical injury rates depending on Russian regions showed that the Republics of Adygea and Kalmykia, Krasnodar Territory, Rostov, Kursk and Astrakhan regions are areas with the greatest prevalence of fatal electrical injury. A comparative data analysis for the Russian Federation with the European Union countries and the CIS countries demonstrates that the fatal electrical injury has a high frequency of occurrence in our country.

INTRODUCTION: Electric shocks may have neurological consequences for the victims. Although the literature on the neurological consequences of electric shocks is limited by retrospective designs, case studies and studies of selected patient groups, previous research provides some evidence of a link between electric shocks, and diseases and symptoms of the central nervous system (CNS)(e.g. epilepsy, migraine and vertigo) and the peripheral nervous system (PNS)(e.g. loss of sensation, neuropathy and muscle weakness). This study aims to employ a register-based, matched cohort study, to investigate whether individuals demonstrate a greater risk of neurological diseases and symptoms of the CNS or PNS in the years following an electrical injury. MATERIALS AND METHODS: We identified 14,112 electrical injuries over a period of 19 years in two Danish registries, and matched these with three different groups of persons in a prospective matched cohort study: (1) patients with dislocation/sprain injuries, (2) patients with eye injuries and (3) persons employed in the same occupation. Year of injury, sex and age were used as matching variables. The outcomes we identified comprised neurological disorders and central or peripheral nervous system symptoms that covered a range of diagnoses in the Danish National Patient Register. The associations were analysed using conditional logistic regression for a range of time periods (six months to five years) and conditional Cox regression for analyses of the complete follow-up period (up to 20 years). RESULTS: For victims of electric shock, the CNS sequelae we identified included an increased risk of epilepsy, convulsions, abnormal involuntary movements, headache, migraine and vertigo. We also identified an uncertain, increased risk of spinal muscular atrophy and dystonia, whereas we identified no increased risk of Parkinson's disease, essential tremor, multiple sclerosis or other degenerative diseases of the nervous system. For victims of electric shock, the PNS sequelae we identified included an increased risk of disturbances of skin sensation, mononeuropathy in the arm or leg and nerve root and plexus disorders. We also identified an uncertain, increased risk of facial nerve disorders, other mononeuropathy, and polyneuropathy. CONCLUSION: Our results confirm that electrical injuries increase the risk of several neurological diseases and symptoms of the CNS or PNS in the years following the injury. Most often the diseases and symptoms are diagnosed within the first six months of the injury, but delayed onset of up to 5 years cannot be ruled out for some symptoms and diagnoses. Some of the conditions were rare in our population, which limited our ability to identify associations, and this warrants cautious interpretation. Therefore, further studies are needed to confirm our findings, as are studies that examine the mechanisms underlying these associations.

BACKGROUND: The recent proliferation of electric standing scooters in major urban areas of the United States has been accompanied by injuries of varying severity and nature, representing a growing public health concern. OBJECTIVE: Our aim was to characterize imaging utilization patterns for injuries associated with electric scooter (e-scooter) use, including their initial emergency department (ED) management. METHODS: We conducted a retrospective review of the electronic medical record for all patients presenting to affiliated EDs for e-scooter-related injuries between July 2018 and April 2020. Demographics, date and time of presentation, imaging study type, resultant injury, and procedural details were recorded. RESULTS: Ninety-seven patients were included; mean age was 27.6 years. Of these, 55 patients (57%) had injuries identified on imaging and 40% of all imaging studies were positive. Most identified injuries (61%) were musculoskeletal, with a small number of neurological (2%) and genitourinary (1%) injuries. The highest prevalence of presentations occurred in August; most patients (72%) presented between 3 pm and 1 am and granular peaks were between 12 am and 1 am and 5 pm and 6 pm. CONCLUSIONS: Patients presenting with e-scooter injuries have a high likelihood of injury to the radial head, nasal bone, and malleoli. Emergency physicians should be especially vigilant for injuries in these areas at presentation. Visceral injuries are uncommon but may be severe enough to warrant surgery.

OBJECTIVE: This study investigates whether individuals who have sustained an electrical injury (EI) are diagnosed with unspecified pain or pain related to the musculoskeletal system in the years following the injury. METHODS: Individuals listed in Danish registers as having sustained EIs were matched for sex, age, and year of injury in a cohort study with individuals having experienced dislocations/sprains (match 1), eye injuries (match 2), and a sample of individuals with the same occupation without a history of electrical injuries (match 3). Outcomes were unspecified pain and unspecified soft tissue disorders. Conditional logistic regression and conditional Cox regression were applied. RESULTS: We identified 14,112 individuals who sustained EIs. A higher risk of both outcomes was observed for all three matches, and was highest at the 6- and 12-month follow-ups. The risk of both outcomes was considerably higher for match 3. CONCLUSIONS: This study confirms that exposure to EIs increases the risk of being diagnosed with unspecified pain or unspecified soft tissue disorders both at short and long terms. Our results also showed that the risk of unspecified pain as sequelae is related to the severity of the injury.

INTRODUCTION: People exposed to electrical injuries are often admitted to hospital for observation. Current evidence suggests that patients who have a normal ECG on admission after a low-voltage injury, with no loss of consciousness or initial cardiac arrest may be discharged home after a short observation time. Currently, there are no established standards for the duration of monitoring after electric shock, but 24 h of observation is the most commonly adopted approach. We carried out a retrospective study of patients admitted after electrical injuries to determine the in-hospital outcomes and 30-day mortality in these patients. METHODS: We performed a chart review of all patients with electrical injuries admitted to Østfold Hospital, Norway between the years 2001 and 2019, to determine in-hospital and 30-day mortality and the frequency of various cardiac and non-cardiac complications. RESULTS: Mean age of 465 included patients (88% males) was 31 years. Of all injuries, 329 (71%) were work-related, 17 (3.7%) involved loss of consciousness. Furthermore, 29/437 (6.6%) were high voltage (> 1000 V), and 243/401 (60.6%) were transthoracic injuries. 369 (79.4%) were discharged same day. None of the admitted patients died in hospital nor did any die within 30 days of admission, yielding a 30-day mortality of 0% (95% CI 0-0.8). At admission troponin was elevated in three (0.6%) patients, creatinine kinase (CK) in 30 (6.5%) and creatinine in six (1.3%). Electrocardiogram (ECG) abnormalities were described in 85 (18%) patients. No serious arrhythmias were detected. When comparing high- vs low-voltage or transthoracic vs other injuries, there were no significant differences between most of the outcomes, except for more ECG abnormalities in the transthoracic group, whereas more patients had elevated CK, and fewer discharged the same day in high-voltage injuries. CONCLUSION: No in-hospital nor 30-day mortality or serious arrhythmias were encountered in those who were assessed, regardless of the type of injury. Troponin and creatinine were rarely elevated. It seems that conscious patients admitted with a normal ECG following a low-voltage injury may safely be discharged home after a quick clinical assessment including ECG.

OBJECTIVE: Exposure to electrical current may cause injury with both mental and physiological consequences. This may lead to increased contacts with general practitioners (GP) and the injured person may develop reduced ability to work. We aimed to examine these outcomes in terms of work-participation, long-term sick leave and contacts with GPs. METHODS: In a matched cohort design, we identified 14 112 electrical injuries in two registries and matched these with both patients with distorsion injuries or eye injuries, and with persons from the same occupation, using year of injury, sex and age for matching. We defined the outcomes based on register information regarding contacts with GPs and public transfer income. After the injury, we determined if the person had a long-term sick leave episode during the first 6, 12 months and 5 years. We calculated work participation during the year and 5 years and the number of GP contacts in the year of the injury, the year after and 5 years after the injury and dichotomised this at twice the mean number of contacts in the study population. The associations were analysed using conditional logistic regression. RESULTS: We found increased risk for all defined outcomes, with the highest estimates in the occupation match. The risk estimates were similar over time. Adjusting for previous work participation increased the estimates slightly, whereas adjusting for previous contacts with GPs reduced the estimates. Restricting to those with at longer hospitalisation increased the estimates. CONCLUSION: Electrical injuries increase risk of long-term sick leave, low work participation and increased contacts with GPs.

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.

BACKGROUND: The hospital departments for occupational medicine and the National Institute of Occupational Health (STAMI) established a shared, anonymous patient register in 2009. This report describes the diagnoses, occupations and exposure factors that occur most frequently in the youngest patient group. This will reflect exposures in modern working life in particular, and thus produce important knowledge with regard to targeted prevention efforts. MATERIAL AND METHOD: We have undertaken a descriptive analysis of 910 examinations of patients in the age group 20-29 years, performed in occupational medicine departments in Norway during the period 2010-17. RESULTS: Examinations of patients aged 20-29 years accounted for 914 (8 %) of a total of 11 969 recorded patient examinations. We excluded four participants for whom information on their sex was missing. This age group encompassed 498 (55 %) men, compared to 75 % men in the total dataset. The most frequent diagnoses were asthma (187/910, 21 %), contact eczema (184/910, 20 %) and rhinitis (73/910, 8 %). The most frequent exposure factors were irritants/allergens (469/910, 52 %). The most common occupations were hairdresser (159/910, 17 %) and painter/varnisher (46/910, 5 %). Hairdresser was the predominant occupation among women (154/412, 37 %), while painter/varnisher (35/498, 7 %) and electrician (25/498, 5 %) predominated among men. INTERPRETATION: Young patients who are examined in occupational medicine departments in Norway are most frequently registered with asthma or hand eczema. Hairdressers are especially exposed, indicating a special need for primary prevention in this occupation to prevent development of illness. In cases of asthma and hand eczema, doctors should be aware of the possibility that this might be occupationally related.

BACKGROUND: We aimed to evaluate children who presented with electrical injury to the emergency department. We tried to reveal the complications of these patients and the measures to be taken in this regard. METHODS: Medical records of pediatric patients who were admitted with electrical injury to emergency department between January 2007 and January 2012 were retrospectively reviewed. An information form was completed about demographic data, clinical features, exposure place, electrical current type, clinical course, duration of hospitalization, electrocardiography, echocardiography and other systems findings. RESULTS: Children who were the most exposed to electrical injury were children 4 years and under. While low-voltage current exposure was more common in younger ages, high-voltage current exposure was more common in older ages. Most of our patients (%72) were exposed to low voltage. Patients who exposed to high-voltage electricity had significantly higher levels of CPK, CK-MB, LDH, AST, and ALT compared to patients who were exposed to low voltage electricity. None of the patients have died. CONCLUSION: Young children are often exposed to electric shock at home. Increasing precautions to be taken at home reduces electrical shock injuries. Children and especially families should be educated in this regard.

BACKGROUND: The risk of death or appropriate therapy varies widely among recipients of implantable cardioverter-defibrillators (ICDs). The goals of this study were to develop a risk prediction tool that jointly considers future outcome probabilities of ICD shock and death. METHODS AND RESULTS: We performed a secondary analysis of patients receiving ICDs as part of the SCD-HeFT trial (Sudden Cardiac Death in Heart Failure Trial). We applied an illness-death regression model to jointly model both ICD shocks and death under the semi-competing risks framework, which predicts for each patient their probability of having received ICD shocks, dying, or both at any given point in time. Among 803 ICD recipients (mean age, 60 years; 23% women) followed for a median of 41.1 months, 430 (53.5%) patients completed the study without dying or receiving an ICD shock, 206 (25.7%) received at least 1 shock but survived, 113 (14.1%) died before experiencing a shock, and 54 (6.7%) received at least 1 shock and subsequently died. Predicted outcome probabilities based on baseline demographic and clinical variables reveal substantial heterogeneity in joint shock and death risks, both between patients at each time point and for each single patient across time. Overall, predictive performance for ICD shock and death individually was adequate, based on area under the curve at 5 years of 0.65 for shocks and of 0.79 for death. CONCLUSIONS: Our analysis of outcomes after ICD implantation provides an alternative predictive model for individual risk of death or ICD shocks. If validated, this may provide a useful tool for individualized counseling regarding likely outcomes after device implantation, while also informing the design of further studies to focus the clinical effectiveness and cost-effectiveness of ICD therapy.

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.

OBJECTIVE: Patients with electrical injury are considered to be at high risk of cardiac arrhythmias. Due to the small number of studies, there is no widely accepted guideline regarding the risk assessment and management of arrhythmic complications after electrical accident (EA). Our retrospective observational study was designed to determine the prevalence of ECG abnormalities and cardiac arrhythmias after EA, to evaluate the predictive value of cardiac biomarkers for this condition and to assess in-hospital and 30-day mortality. METHODS: Consecutive patients presenting after EA at the emergency department of our institution between 2011 and 2016 were involved in the current analysis. ECG abnormalities and arrhythmias were analyzed at admission and during ECG monitoring. Levels of cardiac troponin I, CK and CK-MB were also collected. In-hospital and 30-day mortality data were obtained from hospital records and from the national insurance database. RESULTS: Of the 480 patients included, 184 (38.3%) had suffered a workplace accident. The majority of patients (96.2%) had incurred a low-voltage injury (< 1000 V). One hundred and four (21.7%) patients had a transthoracic electrical injury while 13 (2.7%) patients reported loss of consciousness. The most frequent ECG disorders at admission were sinus bradycardia (< 60 bpm, n = 50, 10.4%) and sinus tachycardia (> 100 bpm, n = 21, 4.4%). Other detected arrhythmias were as follows: newly diagnosed atrial fibrillation (n = 1); frequent multifocal atrial premature complexes (n = 1); sinus arrest with atrial escape rhythm (n = 2); ventricular fibrillation terminated out of hospital (n = 1); ventricular bigeminy (n = 1); and repetitive nonsustained ventricular tachycardia (n = 1). ECG monitoring was performed in 182 (37.9%) patients for 12.7 ± 7.1 h at the ED. Except for one case with regular supraventricular tachycardia terminated via vagal maneuver and one other case with paroxysmal atrial fibrillation, no clinically relevant arrhythmias were detected during the ECG monitoring. Cardiac troponin I was measured in 354 (73.8%) cases at 4.6 ± 4.3 h after the EA and was significantly elevated only in one resuscitated patient. CK elevation was frequent, but CK-MB was under 5% in all patients. Both in-hospital and 30-day mortality were 0%. CONCLUSIONS: Most of cardiac arrhythmias in patients presenting after EA can be diagnosed by an ECG on admission, thus routine ECG monitoring appears to be unnecessary. In our patient cohort cardiac troponin I and CK-MB were not useful in risk assessment after EA. Late-onset malignant arrhythmias were not observed.

We explored the associations of occupational exposure to extremely low-frequency magnetic fields (ELF-MF) and electric shocks with the risk of amyotrophic lateral sclerosis (ALS) in a pooled case-control study (European Multidisciplinary ALS Network Identification to Cure Motor Neurone Degeneration (Euro-MOTOR)) of data from 3 European countries. ALS patients and population-based controls were recruited in Ireland, Italy, and the Netherlands between 2010 and 2015. Lifetime occupational and lifestyle histories were obtained using structured questionnaires. We applied previously developed job exposure matrices assigning exposure levels to ELF-MF and potential for electric shocks. Odds ratios and 95% confidence intervals were estimated by means of logistic regression for exposure to either ELF-MF or electric shocks, adjusted for age, sex, study center, education, smoking, and alcohol consumption and for the respective other exposure. Complete occupational histories and information on confounding variables were available for 1,323 clinically confirmed ALS cases and 2,704 controls. Both ever having had exposure to ELF-MF above the background level (odds ratio = 1.16, 95% confidence interval: 1.01, 1.33) and ever having had potential exposure above background for electric shocks (odds ratio = 1.23, 95% confidence interval: 1.05, 1.43) were associated with ALS. Adjustment for the respective other exposure resulted in similar risk estimates. Heterogeneity in risks across study centers was significant for both exposures. Our findings support possible independent associations of occupational exposure to ELF-MF and electric shocks with the risk of ALS.

INTRODUCTION: Combined burn trauma is rather uncommon and frequently difficult to manage. Historically combined burn trauma contributed to high mortality rates in severely injured patients. The purpose of this study was to determine the incidence, mechanisms and impact of non-thermal injuries in patients with severe burns. METHODS: The charts of 2536 patients admitted to the Burn Center of the University Hospital Zurich between 1977 and 2013 were reviewed and retrospectively analyzed. Patients with additional injuries were identified and analyzed statistically. RESULTS: Over 35 years from 1977 to 2013 a total of 100 burn patients (3.9%) with additional trauma were identified. Motor vehicle crash was the most common mechanism of injury (44%) from 1977 to 1995, compared to electrical injury (33%) from 1996 to 2013. Skeletal trauma including spinal and pelvic injury was the most common form (71%). Additional thoracic or abdominal trauma represented the highest risk factor for in-hospital mortality (adjusted RR 2.2, 95% CI 0.6-7.6). However, after 1995 the presence of any form of additional injury did not have a significant impact on in-hospital mortality (unadjusted RR 0.97, 95% CI 0.5-1.7, pâ¯=â¯0.914). CONCLUSIONS: Concomitant trauma did not reveal a significant impact on in-hospital mortality in our burn center recently. Retrospectively, trauma mechanisms shifted from motor vehicle crashes to electrical injuries in our population. Safety measures for motor vehicles and adequate emergency room algorithms seem to have contributed to a reduction of severity of injury and mortality.

OBJECTIVE: Electrical injuries in swimming pools are an important pediatric public health concern. We sought to (1) improve our understanding of the clinical presentation and outcomes following and (2) describe the epidemiology of swimming pool electrical injuries in the United States. METHODS: We reviewed 4 cases of pediatric (<18 y old) electrical injury from a single, urban level 1 pediatric trauma center. We also queried the National Electronic Injury Surveillance System (NEISS) for emergency department visits due to electrical injury associated with swimming pools, occurring between 1991 and 2013. RESULTS: Overall, 566 cases were reported, with a mean (SD) age of 9.2 (4.1) years. Patients were mostly treated and released from the emergency department (91.8%), whereas 8.2% were hospitalized. When stated, injuries occurred most frequently at home (57.0%), followed by public (23.9%) and sports facilities (19.1%). Electrical outlets or receptacles (39.8%) were most commonly implicated, followed by electrical system doors (18.2%), electric wiring systems (17.0%), thermostats (16.3%), hair dryers (4.6%), and radios (4.1%). Pediatric cases represented 48.4% of swimming pool-related electrical injuries reported to NEISS. CONCLUSIONS: Electrical injuries occurring in and around swimming pools remain an important source of morbidity and mortality. Although NEISS monitors sentinel events, current efforts at preventing such cases are less than adequate. All electrical outlets near swimming pools should be properly wired with ground fault circuit interrupter devices. Possible approaches to increasing safe electrical device installation are through strengthening public awareness and education of the potential for injury, as well as changes to current inspection regulations.

OBJECTIVE: An electrical injury (EI) is an emergency that causes high morbidity and mortality each year. The aim of this study was to define the epidemiological, clinical, and laboratory factors that might predict severe patients and cardiac arrest in pediatric EI cases. METHODS: All of the patients' medical files were reviewed retrospectively through a 2-year period for the demographic, clinical, and laboratory findings. The patients were classified into the severe injury group or the mild injury group. The SPSS (Chicago, Ill) software was used to analyze the data. RESULTS: Among the 38 patients, 18 patients (47.4%) were in the mild group, and 20 patients (52.6%) were in the severe group. Low-voltage injuries were observed in 35 (92.1%) of the patients. Most of the severe patients were injured with low voltage (75%) and in household settings (85%). Plug and sockets were the most observed source of the injuries in all of the patients, whereas water-related injuries were most prevalent in the severe group. The source of injury was different in the mild and severe groups (P = 0.009). In the severe group, 13 patients (34.2%) were resuscitated after cardiopulmonary arrest. In the multivariate analysis of the demographic data, the most predictive parameters for cardiac arrest and the clinical severity in EIs are the factors of electrical cables and water. CONCLUSIONS: Electrical injuries are a significant concern in the pediatric population. Our results showed that low voltage and household electricity could cause morbidity and mortality.

IntroductionAlthough death due to electrical injury and lightning are rare in children, these injuries are often preventable. Twenty years ago, most injuries occurred at home, precipitated by oral contact with electrical cords, contact with wall sockets and faulty electrical equipment. We sought to assess the epidemiology of electrical injuries in children presenting to Emergency Departments (EDs) that participate in the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP). METHODS: This study is a retrospective review of electrical and lightning injury data from CHIRPP. The study population included children and youth aged 0-19 presenting to participating CHIRPP EDs from 1997-2010. Age, sex, year, setting, circumstance and disposition were extracted. Variables were tested using Fisher's exact test and simple linear regression. RESULTS: The dataset included 1183 electrical injuries, with 84 (7%) resulting in hospitalization. Most events occurred at home in the 2-5 year age group and affected the hands. Since 1997 there has been a gradual decrease in the number of electrical injuries per year (p<0.01) and there is an annual surge in electrical injuries over the summer (p<0.01). Forty-six percent of injuries involved electrical outlets, 65% of injuries involved some sort of electrical equipment. Injuries due to lightning were rare (n=19). No deaths were recorded in the database. CONCLUSION: Despite the decrease in the number of electrical injuries per year, a large portion of injuries still appear to be preventable. Further research should focus on effective injury prevention strategies.
