Abstract
Electrical trauma is associated with significant morbidity and mortality, which have been reduced by improved medical care, as measured by the length of stay (LOS) as a marker for this population's quality of care. This paper will review the clinical and demographic characteristics, LOS in the hospital, and variables related to patients with electrical burns. A retrospective cohort study was conducted at a specialized burn unit in Southwest Colombia. Five hundred seventy-five electrical burn-related admissions from 2000 to 2016 were reviewed for the LOS and variables including patient-related (age, gender, marital status, education, and occupation), location of the accident (domestic vs labor-related), voltage, direct contact, arc, flash, flame, clinical presentation (burn surface area, depth, single or multiple organ injury, secondary infection, and abnormal labs), and treatment (surgical procedures and intensive care unit [ICU] admission). Univariate and bivariate analysis, with its 95% CI (confidence interval). We also performed a multiple logistic regression. LOS was correlated to males, age greater than 20 years, construction workers, high voltage injuries, severe burns by area and depth, infection, ICU admission, and multiple surgical procedures or extremity amputation. LOS due to electrical injury was observed to be significantly associated with the following variables, carpal tunnel release (OR [odds ratio]= 4.25, 95% CI [confidence interval] 1.70-5.20); amputation (OR = 2.81, 95% CI 1.60-5.10); infection (OR = 2.60, 95% CI 1.30-5.20); site of infection, mainly wound (OR = 1.30, 95% CI 1.10-1.44); associated injury (OR = 1.72, 95% CI 1.00-3.24); work or domestic accident (OR = 1.83, 95% CI 1.00-3.32); aged 20-40 years (OR = 1.41, 95% CI 1.00-2.10); CPK (OR = 1.40, 95% CI 1.00-2.00); and third-degree burns (OR = 1.55, 95% CI 1.00-2.80). Risk factors for LOS secondary to electrical injury should be appropriately addressed. Prevention at high-risk workplaces is imperative. Mitigating the injury with appropriate management of infection and timely surgical interventions play an essential role in the successful treatment of these patients.

Abstract
OBJECTIVE To develop the algorithm for correction of defects following high-voltage electrical trauma with revascularized autografts, to assess the incidence and risk factors of postoperative complications. MATERIAL AND METHODS Surgical interventions were performed in 16 men. Autografts were selected considering localization of defect and preoperative ultrasound data on perfusion of donor and recipient areas. We applied a sample with temporary compression of the vessels and ultrasound scanning of arteries and veins (a small-sized Doppler sound indicator of blood flow velocity - MINIDOP, BIOSS). RESULTS Nine patients underwent microsurgical transplantation of revascularized flaps. Six patients with electrical trauma of the upper extremities underwent transplantation of free skin autografts and transposition of flexor and extensor muscles of the fingers in various combinations. In 1 patient, simultaneous microsurgical graft transplantation and plasty with local tissues were carried out. Microsurgical transplantation of thoracodorsal flap was performed in 2 patients with maxillofacial defect (with preliminary deepidermization of the flap in one case). In 3 patients with traumatic amputation of the penis, 2 patients underwent phalloplasty with a thoracodorsal flap and prefabrication of a radial forearm graft at the first stage. At the next stage, urethroplasty with a prefabricated radial forearm graft was performed. In 1 patient, closure of the penis defect was carried out using scrotal flaps. CONCLUSION An integrated surgical approach, the use of free revascularized autografts and adequate postoperative management ensure high-quality aesthetic and functional restoration, improvement of the quality of life and social adaptation of patients with defects and deformations following high-voltage electrical injury.

Abstract
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.

Emerg Med J 2019; 36:176-182. [PMID: 30635272 PMCID: PMC6580756 DOI: 10.1136/emermed-2018-207900] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 12/07/2018] [Accepted: 12/20/2018] [Indexed: 11/16/2022]
Abstract
Background Low/middle-income countries carry a disproportionate burden of the morbidity and mortality from thermal burns. Nearly 70% of burn deaths worldwide are from thermal burns in India. Delays to medical care are commonplace and an important predictor of outcomes. We sought to understand the role of emergency medical services (EMS) as part of the healthcare infrastructure for thermal burns in India. Methods We conducted a prospective observational study of patients using EMS for thermal burns across five Indian states from May to August 2015. Our primary outcome was mortality at 2, 7 and 30 days. We compared observed mortality with expected mortality using the revised Baux score. We used Χ2 analysis for categorical variables and Wilcoxon two-sample test for continuous variables. ORs and 95% CIs are reported for all modelled predictor variables. Results We enrolled 439 patients. The 30-day follow-up rate was 85.9% (n=377). The median age was 30 years; 56.7% (n=249) lived in poverty; and 65.6% (n=288) were women. EMS transported 94.3% of patients (n=399) to the hospital within 2 hours of their call. Median total body surface area (TBSA) burned was 60% overall, and 80% in non-accidental burns. Sixty-eight per cent of patients had revised Baux scores greater than 80. Overall 30-day mortality was 64.5%, and highest (90.2%) in women with non-accidental burns. Predictors of mortality by multivariate regression were TBSA (OR 7.9), inhalation injury (OR 5.5), intentionality (OR 4.7) and gender (OR 2.2). Discussion Although EMS rapidly connects critically burned patients to care in India, mortality remains high, with women disproportionally suffering self-inflicted burns. To combat the burn epidemic in India, efforts must focus on rapid medical care and critical care services, and on a burn prevention strategy that includes mental health and gender-based violence support services.

Abstract
Purpose: To elucidate the manifestations of ocular injuries in the colored corn starch dust explosion at a Taiwan water park. Methods: This is a retrospective, non-comparative, consecutive-interventional case series. Fifty explosion-injury patients on 27 June 2015 treated at Chang-Gung Memorial Hospital, Linkou, were included. Thorough ophthalmic examinations were based on emergent triage and consecutive ophthalmological consultations. Multiple ocular and systemic parameters were assessed. Results: Of the 100 eyes in the 50 cases reviewed, 22 cases were male and 28 cases were female. The mean age was 22.08 ± 4.64 years, and the mean burn total body surface area (TBSA) of patients was 45.92 ± 20.30%. Of the 50 patients, 20 had Grade 1 ocular burns, and the others were without ocular involvement. Two of the 20 cases that presented Grade 1 ocular burns died within 1 month due to other systemic complications. The most common ocular manifestations among those with ocular injuries included periocular swelling (75%), followed by conjunctival chemosis (65%), conjunctival hyperemia (50%), singed eyelashes (20%), cornea epithelial defects (10%), and punctate keratopathy (5%). It is worth mentioning that one patient developed herpes simplex keratitis due to stress 3 weeks after being burned. Half of the 50 patients had facial burns. Specifically, the patients with a greater TBSA presented more significant ocular-burn manifestations than those patients with lower TBSA. Conclusion: Prompt ophthalmologic consultations are particularly necessary for mass burn-casualty patients with facial burns, inhalation injuries, and greater TBSA. The inspection and control of all ignition sources and the manipulation of dust with low concentrations and in an open space are crucial factors to prevent future dust explosions.

Development of a long-term ovine model of cutaneous burn and smoke inhalation injury and the effects of early excision and skin autografting. Burns 2012; 38:908-16. [PMID: 22459154 DOI: 10.1016/j.burns.2012.01.003] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2011] [Revised: 01/04/2012] [Accepted: 01/06/2012] [Indexed: 10/28/2022]
Abstract
UNLABELLED Smoke inhalation injury frequently increases the risk of pneumonia and mortality in burn patients. The pathophysiology of acute lung injury secondary to burn and smoke inhalation is well studied, but long-term pulmonary function, especially the process of lung tissue healing following burn and smoke inhalation, has not been fully investigated. By contrast, early burn excision has become the standard of care in the management of major burn injury. While many clinical studies and small-animal experiments support the concept of early burn wound excision, and show improved survival and infectious outcomes, we have developed a new chronic ovine model of burn and smoke inhalation injury with early excision and skin grafting that can be used to investigate lung pathophysiology over a period of 3 weeks. MATERIALS AND METHODS Eighteen female sheep were surgically prepared for this study under isoflurane anesthesia. The animals were divided into three groups: an Early Excision group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke followed by early excision and skin autografting at 24h after injury, n=6), a Control group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke without early excision, n=6) and a Sham group (no injury, no early excision, n=6). After induced injury, all sheep were placed on a ventilator and fluid-resuscitated with Lactated Ringers solution (4 mL/% TBS/kg). At 24h post-injury, early excision was carried out to fascia, and skin grafting with meshed autografts (20/1000 in., 1:4 ratio) was performed under isoflurane anesthesia. At 48 h post-injury, weaning from ventilator was begun if PaO(2)/FiO(2) was above 250 and sheep were monitored for 3 weeks. RESULTS At 96 h post-injury, all animals were weaned from ventilator. There are no significant differences in PaO(2)/FiO(2) between Early Excision and Control groups at any points. All animals were survived for 3 weeks without infectious complication in Early Excision and Sham groups, whereas two out of six animals in the Control group had abscess in lung. The percentage of the wound healed surviving area (mean ± SD) was 74.7 ± 7.8% on 17 days post-surgery in the Early Excision group. Lung wet-to-dry weight ratio (mean ± SD) was significantly increased in the Early Excision group vs. Sham group (p<0.05). The calculated net fluid balance significantly increased in the early excision compared to those seen in the Sham and Control groups. Plasma protein, oncotic pressure, hematocrit of % baseline, hemoglobin of % baseline, white blood cell and neutrophil were significantly decreased in the Early Excision group vs. Control group. CONCLUSIONS The early excision model closely resembles practice in a clinical setting and allows long-term observations of pulmonary function following burn and smoke inhalation injury. Further studies are warranted to assess lung tissue scarring and measuring collagen deposition, lung compliance and diffusion capacity.

Abstract
Pharmacologic modulation of hypermetabolism clearly benefits children with major burns, however, its role in adult burns remains to be defined. Oxandrolone appears to be a promising anabolic agent although few outcome data are as yet available. We examined whether early oxandrolone treatment in severely burned adults was associated with improved outcomes during acute hospitalization. We evaluated for potential associations between oxandrolone treatment and outcomes in a large cohort of severely burned adults in the context of a multicenter observational study. Patients were dichotomized with respect to oxandrolone treatment, defined as administration within 7 days after admission, with duration of at least 7 days. Acute hospitalization outcomes were compared with univariate and multivariate analyses. One hundred seventeen patients were included in this analysis. Mean patient age was 42.6 years (range, 18-86); 77% were male, with an average TBSA of 44.1%. Baseline and injury characteristics were similar among treatment and nontreatment cohorts. Oxandrolone treatment (N = 59) did not impact length of stay but was associated with a lower mortality rate (P = .01) by univariate analysis. Oxandrolone treatment was independently associated with higher survival by adjusted analyses (P = .02). Examination of early oxandrolone treatment in this cohort of severely burned adults suggests that this therapy is safe and may be associated with improved survival. Further studies are necessary to define the exact mechanisms by which oxandrolone is beneficial during inpatient treatment.

Abstract
Chemical or radiant energy injuries to the eyes are considered ocular burns. The majority of these injuries are occupation-related. Chemical burns are by far more common and represent a true emergency. Thermal and UV injuries are associated with severe pain, but often result in less long-term sequelae than chemical injuries do. The term "biologic exposure" refers to an exposure to human blood or other body fluid. This article describes patterns of these injuries and exposures, with particular emphasis on emergent management and including acute diagnostic and treatment considerations.
