A survey on 30 months electrical burns in Shiraz University of Medical Sciences Burn Hospital

Electrical burn is less common nowadays but still has complications and requires therapeutic interventions especially in developing countries. It occurs more in males and in industrial sites. The importance of electrical burn led us to study a 30 months history of electrical burn in Shiraz, Southern Iran. In a cross-sectional retrospective study, 1352 patients were surveyed for 30 months in relation to the cause, time, demographic information, therapeutic measures and prognosis of the electrical burn. Among burn patients, 4.73% were due to electrical burns (mean age, 30.5 years) and 95.3% were male. The mean hospitalization period was 11.5 days and the mean burn extent was 27.5%. Half of the victims were employees and 59.3% of the electrical burns occurred at their work site. 67.2% of burns were due to high voltage electrical current (more than 1000 V) and 4.6% of the patients died due to the direct cause of electrical burn. The high prevalence of electrical burn in males and workers emphasizes on the essence of standardization of occupational areas and use of trained workers to prevent electrical burns.     

Quality of life and return to work following electrical burns

To investigate the psychosocial outcomes following electrical burns, a cross-sectional survey of electrical burn patients was done using three outcome tools: the Burn Specific Health Scale brief version (BSHS-B), the Coping with Burns Questionnaire (CBQ), and the Pain Patient Profile (P3). Questionnaires were mailed to electrical burn patients discharged from an adult regional burn centre, and also distributed to attendants of an electrical utility conference in Toronto. Twenty-six of 88 patients who were discharged from the regional burn centre during the study period with updated residential information were contacted and 14 (54%) completed the questionnaires. Twenty questionnaires were also distributed at the conference and 8 (40%) were completed; leaving a total of 22 (48%) patients for the study. The average patient age was 44.0+/-11.7 years; 21 (96%) were men, and the average time from injury to survey completion was 5.3+/-4.9 years. Five (23%) of the 22 patients returned to the same work duties, 10 (45%) changed duties, and 7 (32%) did not return to work. BSHS-B scores were low for all patients. Participants with high voltage burns (>1000 V) had worse sexuality scores (p<0.05), while those with larger burns (>10% TBSA) had worse physical scores (p<0.05). Patients surveyed >5 years from injury showed improvement in physical scores. CBQ scores indicated that optimism was the most commonly used coping strategy. P3 showed significant levels of emotional distress in all patients, with anxiety being more common in high voltage injuries (p<0.05). The data suggests that electrical burn patients may have a limited ability to return to work and an overall poor quality of life. Emotional distress is the dominant feature influencing long-term outcome in these patients. Further studies are warranted to validate these findings.     

High tension electrical burns

Summary In this study, 85 patients with high-tension electrical burns who were seen in an 11 year period were reviewed. Only victims with documented passage of high-tension electrical current (more than 1000 volts) through the body were included. A total of 210 operations were performed for exploration, debridement and closures of the injuries; 44 cases underwent a total of 65 amputations. Acute renal failure developed in two cases (2.3%) and both died. No cases of clostridial infection occurred. Four patients (4.7%) died in this series. We came to the conclusion that the primary treatment of these burns must include aggressive fluid resuscitation and early aggressive debridement.Presented at the IV European Burns Congress in Barcelona, Spain, September 23–26, 1991     

Electrical flash burns due to switchboard explosions in New South Wales--a 9-year experience

Purpose

To document the incidence and outcome of flash burns due to electrical switchboard explosions presenting to Concord Hospital Burns Unit, from January 2000 to December 2008.

Methods

The Concord Hospital Burns Unit Database was reviewed for admissions due to electrical burns from January 2000 to December 2008.

Results

There were 119 electrical burns admitted during the study period, 20 of which were due to high voltage current. Ninety-nine others were low voltage injuries and included 37 cases of electrical burns due to low voltage electrical switchboard explosions. All of the electrical switchboard burns occurred in male electricians. Twenty-one of the 37 low voltage injuries required admission and 7 of them required skin grafting. The mean LOS was 9.95 days. Twenty cases suffered serious complications including major psychological problems and ocular injuries.

Conclusions

Flash burns resulting from switchboard explosions account for a significant proportion of all electrical burns presenting to our institution. These burns may highlight deficits in taking safety precautions and the use of personal protection equipment. Despite the small area of injury the long term psychological sequelae were significant resulting in a delayed return to employment, and there was a high incidence of eye injuries. Additional efforts are therefore required towards the prevention of such injuries.     

Electrical burns in sports fishing: A case report

Electrical burns are among the most devastating types of burns, with wide-ranging injuries. They can sometimes occur in the context of fishing, usually involving high voltages.The authors present the case of a 59-year-old-man who suffered a sports accident during a fishing competition, with the formation of an electrical arc due to proximity of the fishing rod and high voltage cables. He presented burns affecting 3% of TBSA, third degree deep burns on trunk and left hand; no signs of cardiac injury. He was admitted to our Burn Unit for monitoring, care dressing and surgical treatment; complete wound healing was achieved after 24 days.Due to its relatively small share among burns, published data on electrical injuries and fishing remain scarce, and differ in patient collectives due to infrastructural or environmental differences. The authors are not aware of published specific reports on electrical burns in sports fishing practice, like the case here presented.The authors want to alert for potential medical, social and economic consequences of this type of sports accidents that could be entirely avoidable with some preventive measures.     

Custom-fit polymeric membrane dressing masks in the treatment of second degree facial burns

Second degree facial burns usually impart high wound site pain levels and patient discomfort due to the abundance of facial sensory innervation, as well as the development of edema and inflammation that accompany wound healing. Frequent changing of adherent dressings causes additional procedural pain and may prolong healing due to recurring damage to the wound bed. We applied face masks, made on-site from a drug free polymeric membrane dressing, to 8 patients with superficial and deep 2nd degree facial burns. Time to full re-epithlialization was recorded during treatment. Pain, overall comfort, and result satisfaction were evaluated using a questionnaire (10-point Likert scales. From 1 = minimum to 10 = maximum) on follow-up (mean follow up 14.4 months, range 9–18). These results were compared to a historical cohort of patients with facial burns that were treated with an antibiotic ointment. Results showed mean re-epithelialization time of 6.5 days (as compared to 8.5 days in the cohort group), low pain ratings (mean: 2.6; range: 4.7 in the control group), mixed comfort levels (mean: 4.7/10; 4 in the control group) and high result satisfaction (mean: 7.8; 6.2 in the control group). Nursing staff described pain-free dressing changes and positively noted non-adherence and high absorbance capacity of the polymer, necessitating less dressing changes. Inflammation was contained to the actual site of injury. No complications in terms of infection or allergic reaction were observed. Overall, the polymeric membrane facial dressing seems to be a promising means of reducing pain and ensuring uninterrupted wound healing in 2nd degree facial burns.     

A voltage-based analysis of fluid delivery and outcomes in burn patients with electrical injuries over a 6-year period

IntroductionElectrical injuries are associated with significant morbidity for affected patients. While cardiac and surgical interventions have been extensively reported, no practice guidelines or studies have specifically addressed fluid delivery and associated outcomes of patients with electrical injuries. The study objective was to evaluate the differences in fluid delivery in patients with high (≥1000 V) and low (<1000 V) voltage electrical injuries.MethodsThis retrospective, observational study included adult electrical injury patients admitted for acute care. Patients with reported voltages were classified into high and low voltage subgroups. Primary outcomes of fluid administration and urine output over the first 24 h after injury were assessed between subgroups. Secondary outcomes included renal, cardiac, surgical, and additional complications such as mortality, cost, and length of stay.ResultsData were analyzed in 36 patients with reported voltages, including 26 patients in the high and 10 patients in the low voltage subgroups. Patients in the high voltage subgroup had a statistically significant higher median (IQR) total IV fluid given [46.6 (22.4–61.9) vs. 22.5 (8.3–31.4) mL/kg, p = 0.033] in the first 24 h to achieve a similar urine output to the low voltage subgroup. The high voltage patients had higher rates of myoglobinuria, rhabdomyolysis, and creatinine kinase elevation. Patients in the high voltage vs. low voltage group had significantly longer median (IQR) length of stay (days) [11 (2–19) vs. 1 (1–6); p = 0.015] and higher cost of hospital stay [$124,608 (19,486–296,991) vs. $16,165 (12,409–69,659); p = 0.033].ConclusionsThese results reinforce the importance of assessing electrical injuries and obtaining a voltage to provide patient-specific care, as high voltage electrical injuries receive more fluid than estimated maintenance rates. This study is the first of its kind to characterize fluid given for high and low voltage electrical injuries and effects on patient outcomes.     

Enzymatic debridement for circumferential deep burns: the role of surgical escharotomy

IntroductionCircumferential deep burns carry a high risk for a burn induced compartment syndrome. It was recently shown that an enzymatic bromelain-based debridement with Nexobrid® is a safe and efficient procedure to release pressure in deep circumferential extremity burns reducing the need for surgical escharotomy. We therefore herein aimed to analyze the conceptual relation between Nexobrid® and surgical escharotomy.Patients and methodsWe conducted a retrospective study on all patients with circumferential deep partial-thickness or full-thickness burns requiring immediate escharotomy that was either performed by surgical incision or Nexobrid®. Medical records of 792 patients that were treated at the burn center of the University Hospital Zurich between 2016 and 2021 were analyzed.ResultsOverall, 62 patients with circumferential deep partial-thickness or full-thickness burns who received preventive decompression either by Nexobrid® (N = 29) or surgical escharotomy (N = 33), were included. Whilst distribution of age, sex, BMI and type of injury showed no difference between the groups, the ABSI score, TBSA, percentage of third degree burns and mortality were significantly higher in patients who received a surgical escharotomy.ConclusionWhile the use of Nexobrid® to prevent burn induced compartment syndrome has steadily increased, surgical escharotomies were predominantly performed in severely burned patients with a high degree of full-thickness burns. Thus, higher mortality in this patient group needs to be considered with caution and is mainly attributed to the higher TBSA. Although evidence is lacking for the use of Nexobrid® for larger body areas exceeding 15%, escharotomy is also the more reliable and faster approach in such critically burned patients.     

Retrospective evaluation of admission criteria for paediatric electrical injuries

In the medical community, the practice of admitting all electrical burns for 24–48 h of observation, monitoring and laboratory evaluation is widespread. This retrospective review of paediatric electrical burns was conducted to determine which patients may safely be treated as outpatients.

Retrospective analysis of all paediatric burns admitted between 1980 and 1991 identified 35 patients with electrical injuries. Patients were divided into two groups for analysis: those burned by exposure to household voltages (120–240 V; n=26) and those exposed to high voltages, in excess of 1000 V (n=9).

The majority of household electrical injuries occurred secondary to contact with the household 120 V (21/26). Contact with an extremity accounted for the largest number of these injuries (18/26). The mouth was the second most frequent site of injury (7/26). Most of these patients (20/26) had < 1 per cent BSA burn. No patient in the household-voltage group had an arrythmia that required treatment, nor were there any identified examples of compartment syndrome or other vascular complications. Seven patients did require minimal skin grafting. No deaths occurred in either group.

The patients in the household-voltage group were significantly younger. High-voltage electrical injuries occurred in an older patient population and required more aggressive care and surgical intervention. This was evident at the time of initial evaluation. Based on these data, healthy children with small partial-thickness electrical burns and no initial evidence of cardiac or neurovascular injury do not appear to need hospital admission.     

Electrical injuries: a 30-year review.

INTRODUCTION: Electrical injuries currently remain a world-wide problem. This study determines whether electrical injuries at our institution have changed in the past 30 years, and identifies electrical burn complications and any high-risk groups. METHODS: From 1967 to 1997, 185 children admitted to our institute were identified with electrical burns. Fifty-five percent of these electrical burns occurred from 1987 to 1997. RESULTS: During the last 10 years of this study, 43% of the electrical injuries (n = 44) were from low voltage (120-240 V) and 57% (n = 58) from high voltage (>1,000 V). In 17 children, serious low-voltage burns were identified as oral commissure burns. These were treated conservatively with one to two reconstructive procedures within 2 years. High-voltage injuries were mainly identified in male children (age 11 to 18 years). Thirty-three percent of high-voltage burns required amputation, 29% had deep muscle involvement, and 24% required either escharotomy or fasciotomy. No mortalities were reported. CONCLUSION: Although the incidence of low-voltage burns is currently on a steady decline, high-voltage injuries remain a problem, particularly in adolescent males.     

Effects of breathing exercise techniques on the pain and anxiety of burn patients: A systematic review and meta-analysis

This systematic review and meta-analysis aim to summarise the effect of breathing exercise techniques (BET) on the pain and anxiety of burn patients during burn care. A systematic search was performed on international electronic databases such as Scopus, PubMed, and Web of Science, as well as on Iranian electronic databases such as Iranmedex and Scientific Information Database (SID) with keywords extracted from Medical Subject Headings such as ‘Burns’, ‘Bandages’, ‘Pain’, ‘Pain management’, ‘Anxiety’, ‘Breathing’, and ‘Breathing exercise’, which were performed from the earliest to 4 April 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist assessed the quality of randomised control trials (RCTs) and quasi-experimental studies. The current meta-analysis was performed using STATA V.14.0 software. A 95% confidence interval (CI) was used to determine significance levels. Random effect model was used to calculate the weighted mean difference (WMD). A total of 469 burn patients participated in 10 studies. Exactly 58.60% of burn patients were male, and the number of people in the intervention and control groups was equal. The mean age of burn patients was 32.84 (SD = 10.39). Exactly 78.05% of patients had second-degree burns. The mean study duration was 19 weeks. Results of analysis of RCT studies showed BET decreased insignificantly pain severity (WMD: −1.17, 95%CI: −2.54 to 0.21, Z = 1.66, P = .096, I²:97.1%) in the intervention group than control group. However, the results of non-RCTs studies indicated BET significantly decreased pain (WMD: −1.38, 95%CI: −2.16 to −0.61, Z = 3.49, P < .001, I²:88.4%) and anxiety (WMD: −4.91, 95%CI: −9.35 to −0.47, Z = 2.71, P = .03 0.001, I²:88.4%) in the intervention group than control group. Overall, the results of RCTs found BET intervention decreased pain in the intervention group when compared with the control group; however, it was statistically insignificant. Also, results of non-RCT studies showed intervention of BET significantly decreased pain and anxiety in burns patients. More RCTs studies are required for better judgement of the effectiveness of BET intervention in clinical settings.     

Clinical outcomes of isolated lower extremity or foot burns in diabetic versus non-diabetic patients: A 10-year retrospective analysis

Introduction

The incidence of diabetes mellitus (DM) in the United States is expected to increase from 8 per 1000 in 2008 to 15 per 1000 by 2050 [20]. As a result, DM patients will constitute a large proportion of Burn Center admissions, with burns typically due to contact burn or scalding. Peripheral vascular disease (PVD) and peripheral neuropathy (PN) are far more common in DM patients, particularly in those with poorly controlled disease, and are often associated with worse outcomes than non-diabetic (nDM) burn patients. This study sought to analyze whether the outcome of isolated leg and foot burns among DM and nDM individuals differed significantly.

Materials and methods

Retrospective data on 207 consecutive patients (>18 years old) admitted to a Burn Center with isolated leg or foot burns between 1999 and 2009 was collected and analyzed for this study. Age, gender, ethnicity, total body surface area (TBSA), degree of burn, etiology, hospital and burn intensive care unit (ICU), length of stay (LOS), and status at discharge were reviewed. Patients were grouped as diabetic (DM) or non-diabetic (nDM). Differences were analyzed using either the Student's t-test or Chi-square.

Results

43 DM and 164 nDM patients with isolated lower extremity or foot burns were treated during the study period (1999–2009). The mean age of DM and nDM patients was 54.6 and 43.7 years, respectively (p < 0.001). The most common burn etiology was scalding, flame, or contact burn. Percentage of total body surface area (TBSA) burn in DM patients averaged ± standard deviation 1.8 ± 1.3% compared to 1.8 ± 1.6% in nDM (p < 0.9). Among DM patients, 86% (N = 37) of patients suffered third degree burns and 14% (N = 6) of patients had second degree burns compared to 76% (N = 125) of patients and 24% (N = 39) of patients among nDM patients, respectively (p < 0.16). The DM group had significantly higher burn ICU admission rates, 16.3% of patients versus 8.5% of patients (p < 0.001), total length of hospital stay (mean ± standard deviation), 14.1 ± 10 versus 9.8 ± 9.3 days (p < 0.01) and renal failure, 4.7% of patients versus 0.6% of patients (p < 0.05) compared to the nDM group. 93% of DM patients were discharged to home without further medical attention while 4.7% of patients underwent further treatment. In comparison, 85.4% of the nDM patients were discharged home with no further treatment while 8.5% of patients received home care (p < 0.01).

Conclusion

DM patients who suffer isolated burns to the feet or lower extremities have poorer clinical outcomes and more complicated and protracted hospital courses when compared to nDM patients with similar burns. Although diabetics in the current study did not experience larger or more severe burns than nDM patients, they were nearly twice as likely to be admitted to the ICU, spent an average of four days longer in the hospital, and had a higher likelihood of developing renal failure compared to nDM patients.     

Epidemiology of burn injuries presenting to North Carolina emergency departments in 2006–2007

Approximately 600,000 burns present to Emergency Departments each year in the United States, yet there is little systematic or evidence-based training of Emergency Physicians in acute burn management. We retrospectively accessed the North Carolina Disease Event Tracking and Epidemiologic Collection Tool (NC DETECT) database to identify all thermal burns and electrical injuries with associated thermal burns presenting to 92% of North Carolina Emergency Departments over a 1-year period. Results: 10,501 patients met inclusion criteria, 0.3% of all state-wide reported ED visits. Ninety-two percent of burn visits were managed exclusively by Emergency Physicians without acute intervention by burn specialists, including 87% of first degree, 82% of second degree, and 53% of third degree injuries. Only 4.3% were admitted; 4.3% were transferred to another institution. Fifty-five percent were male; 33% were aged 25–44 and 33% presented on weekends. Conclusion: This is the first state-wide study of burn injury and identifies Emergency Physicians as the major providers of acute burn care. Ninety-two percent of 10,501 burn visits, including the majority of severe injuries, were managed exclusively by Emergency Physicians. This supports a need for improved, evidence-based training of Emergency Physicians in the acute management of burns of all types.     

The management of chemical burns

In all reports on severe burns, those due to chemical mechanisms comprise less than 3–4% of the total admitted to hospital as opposed to other more frequent mechanisms such as fire, scalding, electrical and contact with hot solids. These burns have typical features which will be described. The diagnosis, treatment, and handling of these patients raises unique features since treatment should be specific depending on the causative agent. This must be identified, failure to do this leads to incorrect treatment and/or delay in beginning treatment. The incorrect antidote can cause additional problems. This paper describes the local and systemic characteristics of a diverse range of chemical burns and the methods of treatment. Received: 22 September 1998 / Accepted: 12 January 1999     

Combined rectus abdominis muscle/paraumbilical flap and lower abdominal flap for the treatment of type III circumferential electrical burns of the wrist

Background

Type III circumferential electrical burns of the wrist are one of the most severe electrical injuries, involving rather extensive necrosis, progressive blood circulatory embarrassment and a high amputation rate. This injury poses a challenge for vascular reconstruction and wound coverage. The purpose of this study was to evaluate the effectiveness of the combined rectus abdominis muscle/paraumbilical flap and lower abdominal flap for the treatment of type III circumferential electrical burns of the wrist.

Methods

Six men (age, 19–32 years; average, 21 years) with type III circumferential electrical burns of the wrist were included. After thorough debridement, the volar wound was repaired with a partial rectus abdominis muscle/paraumbilical flap and the dorsal wound was repaired with a lower abdominal flap.

Results

Flap survival was complete in all six patients. During a follow-up of 6–12 months, the flaps showed good texture and shape. No abdominal hernia occurred in any patients. The scar on the abdominal wall was acceptable.

Conclusion

The combined rectus abdominis muscle/paraumbilical flap and lower abdominal flap has large wound coverage potential and offers a new, easy, safe option for the treatment of type III circumferential electrical burns of wrist.     

Factors in the choice of oral transmucosal fentanyl citrate dose for adult burns dressings

Factors that influenced the choice of dose of oral transmucosal fentanyl at the time of burns dressing change were investigated in a prospective study. After Ethics committee approval, data was analysed from 29 consecutive patients who had been recruited and consented for a study of pain associated with burns dressings. Patients had completed an 11-point verbal pain intensity score (VRS) prior to and after the dressing change. Analgesic use during for this period was documented. Doses of 600 to 1200 mcg of transmucosal fentanyl (Actiq^®) were given based on individual assessment. The pre-dressing VRS (median [range]) in the 15 patients who received 600 mcg was 8 [3–10] and was higher than the VRS of 6 [2–9] in the 800–1200 mcg group. The time since the burn was longer in the low dose group at 7 [1–22] days compared with 5 [0–50] days in the higher dose group. In addition 73% of the low dose group was prescribed opioids regularly prior to the dressing compared with 57% of the high dose group. The choice of a lower transmucosal fentanyl dose was based on prior use of opioids and the age of the burn rather than on the patient's pain intensity.     

Strom- und Blitzunfall

In medical emergency systems, electrical accidents are rare but potentially life-threatening events for patients, bystanders and emergency medical service (EMS) personnel. Most of the accidents are related to domestic surroundings (240–400 V AC) where the activation of cardiac ventricular fibrillation is the most life-threatening effect. High voltage current (>?1000 V) in industrial facilities and railway systems cause burn injuries due to arc-over. Additionally, damage of the heart and brain is possible which also applies to lightning strikes. Moreover, secondary injuries due to shock, crashing down and muscular contraction have to be considered. Safeguarding bystanders and EMS personnel is considered as the priority to basic life support by first switching off the current as well as electrical grounding in front of and behind the accident site. Medical treatment is individualized depending on the main symptoms and after stabilization, the patient is transported and accompanied to a cardiological, traumatological or burns center.     

Variation of the SOFA score and mortality in patients with severe burns: A cohort study

Multiple organ failure (MOF) is the leading cause of death in patients with burns requiring ICU admission. Quantifying the evolution of MOF, with the SOFA score, over the first few days after a severe burn may provide useful prognostic information. This retrospective cohort study aimed at evaluating the association between the evolution of the SOFA score between day 0 and day 3 and in-hospital mortality. All patients admitted for severe burns at the burn ICU of the Tours University Hospital between 2017 and 2020 and who stayed 3 days or more were included. Severe burns included: total body surface area burned (TBSA) ≥ 20 % or burns of any surface associated with one or more of the following items: (1) organ failure, (2) clinically significant smoke inhalation and/or cyanide poisoning, (3) severe preexisting comorbidities, (4) complex and specialized burn wound care. DeltaSOFA was defined as day 3 minus day 0 SOFA. One hundred and thirty-six patients were included. Median age was 52 years (38?70), median TBSA burned was 24 % (20?38), median day 0 SOFA was 2 (0?4) and median day 3 SOFA was 1 (0?5). In-hospital mortality was 10 %. There was a significant association between deltaSOFA and mortality that persisted after adjustment for age and TBSA (HR 1.37, 95 %CI 1.09–1.72, p < 0.01). Area under the receiver operating characteristics curve for the prediction of mortality by day 0 SOFA and deltaSOFA were 0.79 (95 %CI 0.69–0.89) and 0.83 (95 %CI 0.70–0.95) respectively. After exclusion of patients with TBSA burned< 15 %, deltaSOFA remained independently associated with mortality (HR 1.42 95 %CI 1.09–1.85, p < 0.01). In addition, SOFA variations allowed the identification of subgroups of patients with either very low or very high mortality. In patients with severe burns, SOFA score evolution between day 0 and day 3 may be useful for individualized medical and ethical decisions. Further multicenter studies are required to corroborate the present results.
