Burn injuries and characteristics of burn patients in New South Wales, Australia

A Review of Petrol Burns in Australia and New Zealand

Petrol-related thermal burns cause significant morbidity and mortality worldwide and it has been established that they affect young males disproportionately. Beyond this, we sought to identify the difference in the characteristics and outcomes of burns between males and females in an international population. Such differences may highlight areas for future preventative strategies. The Burns Registry of Australia and New Zealand was used. Petrol burns that resulted in a hospital admission in those 16 years or older between January 2010 and December 2019 were included. A total of 2833 patients were included. The median age was 35 years with most patients being male (88%). Burns from a campfire or burnoffs were most common. Females were more likely to suffer burns due to assault or from deliberate self-harm. The total body surface area affected by burns was higher for females than males (10% vs 8%). Furthermore, females more frequently required ICU admission, escharotomies, and had a longer hospital length of stay. The unadjusted mortality rate for females was more than double the rate for males (5.8% vs 2.3%). This international study demonstrates that whilst men more frequently suffer petrol burns, women suffer more severe burns, require more intensive and longer hospitalizations and have a higher mortality rate. These findings may inform changes in preventative health policies globally to mitigate against these concerning findings.

Gasoline-related injuries and fatalities in the United States, 1995-2014

This descriptive study examines twenty years of gasoline-related fatalities and emergency department treated injuries in the United States, based on data from the US Consumer Product Safety Commission. Thermal burns consistently accounted for the majority (56%) of gasoline-related injuries and for most (82%) gasoline-related deaths, and were commonly (57-71%) associated with the use of gasoline as an accelerant. Poisoning accounted for 13% of injuries and 17% of deaths. The primary poisoning injury pattern was ingestion; the primary fatality pattern was inhalation, with about half of those associated with deliberate abuse. The estimated number of ingestions decreased from 60 to 23% of poisoning-related injuries, while injuries associated with inhalation abuse increased from 6 to 23%. Chemical burns and dermatitis were less represented in the injury data and were primarily associated with gasoline spills or splashes. Gasoline cans reportedly ignited or exploded in about 5% of thermal burn injuries and fatalities. While mandatory requirements for child resistant closures on gasoline cans (a primary intervention) have potentially impacted poisonings, the use of flame mitigation devices to address thermal injuries, if successful, would be a secondary intervention, and could address only a small percentage (about 5%) of injuries and deaths.

Validation of predictive factors of dysphagia risk following thermal burns: a prospective cohort study

PURPOSE

The objective of this study was to prospectively evaluate the validity and reliability of a risk factor model developed for use in predicting dysphagia risk within the first 24 h after injury/hospitalisation in patients with thermal burns.

METHOD(S)

Three hundred and fifty six patients with thermal burns, with or without inhalation injury, who were consecutively admitted to and received management at a quaternary state-wide burn center over a 12 month period, were included. Patients were reviewed for dysphagia risk by nursing staff using an established set of predictive factors. If risk factors for dysphagia were present, referral to speech-language pathology was initiated to investigate swallow function.

RESULT(S)

Of the 356 admissions, 83 patients were identified as meeting one or more risk criteria for dysphagia after burn. Of these, 24.9% (n = 30; 8.42% of the total cohort) presented with dysphagia. Using these criteria, sensitivity and specificity for detection of dysphagia risk were high (100% and 83.74%, respectively). The criteria over identify patients who may be at risk of dysphagia and who require dysphagia assessment (positive predictive value = 36.14%). However, as a set of predictors of dysphagia risk when thermal burn is the only complaint, a negative result reassures that a patient does not have dysphagia (negative predictive value = 100%).

CONCLUSION

Overall, the risk factor model provided a valid measure for predicting dysphagia risk. Incorporating these criteria into a dysphagia screening assessment can ensure an evidence-based pathway for early detection and timely referral to speech-language pathology for patients at risk of dysphagia after thermal burns.

Pattern of childhood burn injuries and their management outcome at Bugando Medical Centre in Northwestern Tanzania

BACKGROUND

Burn injuries constitute a major public health problem and are the leading cause of childhood morbidity and mortality worldwide. There is paucity of published data on childhood burn injuries in Tanzania, particularly the study area. This study was conducted to describe the pattern of childhood burn injuries in our local setting and to evaluate their management outcome.

METHODS

A cross sectional study was conducted at Bugando Medical Centre (in Northwestern Tanzania) over a 3-year period from January 2008 to December 2010. Data was collected using a pre-tested coded questionnaire and statistical analyses performed using SPSS software version 15.0.

RESULTS

A total of 342 burned children were studied. Males were mainly affected. Children aged = 2 were the majority accounting for 45.9% of cases. Intentional burn injuries due to child abuse were reported in 2.9% of cases. Scald was the most common type of burns (56.1%). The trunk was the most commonly involved body region (57.3%). Majority of patients (48.0%) sustained superficial burns. Eight (2.3%) patients were HIV positive. Most patients (89.8%) presented to the hospital later than 24 h. The rate of burn wound infection on admission and on 10th day were 32.4% and 39.8% respectively.Staphylococcus aureus were more common on admission wound swabs, with Pseudomonas aeruginosa becoming more evident after 10th day. MRSA was detected in 19.2% of Staphylococcus aureus. Conservative treatment was performed in 87.1% of cases. Surgical treatment mainly skin grafting (65.9%) was performed in 44 (12.9%) of patients. The overall average of the length of hospital stay (LOS) was 22.12 ± 16.62 days. Mortality rate was 11.7%. Using multivariate logistic regression analysis; age of the patient, type of burn, delayed presentation, clothing ignition, %TBSA and severity of burn were found to be significantly associated with LOS (P < 0.001), whereas mortality rate was found to be independently and significantly related to the age of the patient, type of burn, HIV positive with stigmata of AIDS, CD4 count, inhalation injury, %TBSA and severity of burn (P < 0.001).

CONCLUSION

Childhood burn injuries still remain a menace in our environment with virtually unacceptable high morbidity and mortality. There is need for critical appraisal of the preventive measures and management principles currently being practiced.

Burns in the domestic environment: characteristics and circumstances of accidents

This study characterizes burn accidents in the domestic environment and identifies the circumstances of accidents affecting children, adults or elderly people who need supervision or care. Demographic data and burn characteristics of 61 domestic environment burn victims were collected. The family members of 13 children and one aged adult, who needed supervision or special care, were selected to answer a semi-structured interview. Two thematic groups were identified: social and environmental factors that might have contributed to the burn accidents and circumstances involving the accidents. Risk factors were: low socioeconomic and educational levels of mothers and those responsible for the children at the moment of the accident, small houses considering the number of occupants and unsafe kitchen equipment. Although cases of domestic violence were not identified there was neglect from caregivers. Health professionals should be attentive and investigate the circumstances of accidents involving vulnerable individuals.

Effect of photodynamic therapy on the healing of cutaneous third-degree-burn: histological study in rats

The aim of this study was to conduct a histological assessment of the effect of photodynamic therapy (PDT) on the repairing of third-degree-burn wounds made on the backs of rats with a heated scalpel. Ninety-six rats were divided into groups: G1, control (n = 24), cold scalpel; G2, burned, heated scalpel (n = 24); G3, low-level laser therapy (LLLT) (n = 24), on burns; and G4, photodynamic therapy (PDT) (n = 24), toluidine-O blue (100 microg/ml) and LLLT treatment on burns. The laser (685 nm) was applied in continuous mode, 50 mW, 4.5 J/cm(2), contact mode at nine points (9 s/point). Eight animals in each group were killed at 3 days, 7 days or 14 days after surgery, and tissue specimens containing the whole wounded area were removed and processed for histological analysis; the results were statistically analyzed with Kruskal-Wallis and Dunn's tests (P < 0.05). The results demonstrated significant differences between G2 and G3, and between G2 and G4, at both 3 days and 7 days, with regard to acute inflammation scores; G1 and G2 showed significant differences when compared with G4 at 3 days, with regard to neo-angiogenesis scores; G1 and G2 were statistically different from G3 and G4 at both 3 days and 7 days, with regard to re-epithelization scores; G2 showed statistically significant differences when compared with G3 and G4 with regard to collagen fiber scores at 7 days. LLLT and PDT acted as a biostimulating coadjuvant agent, balancing the undesirable effect of the burn on the wound healing process, acting mainly in the early healing stages, hastening inflammation and increasing collagen deposition.

The epidemiology of burn injuries in an Australian setting, 2000-2006

OBJECTIVES

To describe presentation characteristics of burn leading to death or hospital treatment (i.e. inpatient admissions and emergency department [ED] presentations) across the state of Victoria, Australia, for the years 2000-2006 inclusive.

METHODS

Data were provided by the Victorian Injury Surveillance Unit (VISU) from three different datasets pertaining to burn deaths, hospital inpatient admissions and non-admitted ED presentations. Population estimates were derived from census data provided by Australian Bureau of Statistics.

RESULTS

During the 7-year period, 178 people died and 36,430 were treated for non-fatal burn injury, comprising 7543 hospital admissions and 28,887 non-admitted ED presentations. Males, children aged less than 5 years of age, and the elderly (> or =65 years of age) were at the highest risk of injury. Contact with heat and hot substances represented the major aetiological factor contributing to thermal injuries accounting for 64% of all hospital admissions and 90% of ED presentations. Temporal trends indicate no change in the population rate of burn deaths or hospital admissions during the study period.

CONCLUSIONS

ED presentations and hospital admissions and deaths have remained the same over this study period, but rates of burn remain high in males, children and the elderly. This could be due to variations in the implementation of government prevention and control programs and the divergence in efficient treatments and clinical practices amongst hospital care providers. Therefore, educational efforts for prevention should be the keystone to minimise the incidence of burns.

The use of light photobiomodulation on the treatment of second-degree burns: a histological study of a rodent model

OBJECTIVE

The aim of this investigation was to compare, by light microscopy, the effects of the use of laser photobiomodulation (LPBM) and polarized light (PL) on second-degree burns on rodents.

BACKGROUND DATA

Burns are severe injuries that result in the loss of tissue fluids, destruction of tissues, infection, and shock. With severe and widespread third-degree burns death may occur. Several light sources have been suggested as being effective for improving wound healing.

MATERIALS AND METHODS

Forty five rats were used in this study. A second-degree burn was created on the dorsum of each animal, and the animals were divided into four groups: PL (400-2000 nm, 40 mW, 2.4 J/cm(2)/min); LPBM-1 (780 nm, 35/40 mW, theta approximately 2 mm, 4 x 5 J/cm(2)); LPBM-2 (660 nm, 35/40 mW, theta approximately 2 mm, 4 x 5 J/cm(2)); and untreated animals acted as controls. The treatment was started immediately post-burn at four points around the burned area (laser: 5 J/cm(2) per site). The illumination with PL was performed according to the manufacturer's instructions. Treatments were repeated at 24-h intervals for 7 d. The animals were sacrifice at 3, 5, and 7 d post-burn. The specimens were routinely cut and stained and analyzed by light microscopy using hematoxylin and eosin and Sirius red.

RESULTS

The analysis of the results demonstrated that the damaged tissue was able to efficiently absorb and process the light at all tested wavelengths. LPBM at 660 nm showed better results at early stages of wound healing. However, the use of 780-nm laser light had beneficial effects throughout the experimental period, with the animals growing newly-formed tissue similar to normal dermis.

CONCLUSION

Despite our findings that the use of both types of light energy improved the healing of second-degree burns at the early stages, long-term assessment is needed to verify if this improvement will influence the final results of treatment.

INCREASING NUMBERS OF ADMISSIONS TO THE ADULT BURNS SERVICE AT THE ROYAL ADELAIDE HOSPITAL 2001?2004

BACKGROUND

The purpose of the study was to illustrate the increasing trend in the number of adult burns patients admitted to the Royal Adelaide Hospital and attempt to explain it and to describe the burn patients admitted to the Royal Adelaide Hospital in terms of age, sex, origin, cause and burn size, particularly since the increasing trend began, in an effort to identify a particular group or burn cause, which may make up a large proportion of the increasing numbers.

METHODS

A retrospective review of 1548 acute burn-injured patients using information from the burns unit database between 1996 and 2004 was carried out.

RESULTS

Of 1841 total admissions, 1548 were admitted for acute burn injury. There has been an increase in the number of admissions since 2001 amounting to approximately 20% per annum. The cumulative rise in total admissions 2000-2004 is 107% where the increase in acute burn admission in the same period is 82%. There appears to be no difference whether the patient is from a rural or a metropolitan area. Burns of <10% total body surface area constitute most of the increase and are mainly flame and scald injuries. Chemical and contact burns are proportionately increasing.

CONCLUSION

The increase in acute admissions is mainly due to the increasing presentation of smaller burns to the unit. The statewide rural burn education programme and media exposure following the 2002 Bali bombings may have contributed to the increase in acute admissions.

A global study of hospitalized paediatric burn patients

The global incidence of hospitalized paediatric burn patients is unknown. In order to determine a working estimate of the size of the problem, one approach is to extrapolate from relevant published studies. A literature search of the Medline database was performed to identify epidemiological papers published since 1990, which addressed paediatric burn admissions. Extrapolation from population-based studies allowed global figures to be estimated. The highest incidence of hospitalized paediatric burns patients is in Africa, the lowest in the Americas. Europe, the Middle East and Asia share similar figures, but the considerably larger population of Asia indicates that it bears over half of the world's paediatric burn population. It is unfortunate that despite many published studies describing burn admission, few meet criteria that allow for comparative epidemiological data. More attention needs to be focused on uniformity in data collection and presentation to enhance the value of the data available.

Adult burn injuries in an Emergency Department in Central Anatolia, Turkey: a 5-year analysis

PURPOSE

Burn injuries require a multidisciplinary approach. Emergency Departments can play vital roles in the treatment of burns. The purpose of this study is to investigate the epidemiological and clinical characteristics of the adult burn patients admitted to our Emergency Department and to determine the frequency of the patients who were treated on an outpatient basis and discharged from the Emergency Department.

PROCEDURE

A retrospective review of 314 adult burn patients who presented to the Emergency Medicine Department of Erciyes University Hospital from January 1996 to December 2000.

FINDINGS

Sixty-four percent of the patients were male. Mean age was 32.9+/-14.7. Ninety-nine patients (32%) had moderate to major burns. The highest numbers of patients were in the 21-30 age group. Flame burns comprised the majority of presentations and admissions (48 and 69%, respectively). Thirteen patients had associated injuries (4%). Eighty-seven patients (28%) were hospitalized, 21 of these died. Death occurred mostly from respiratory failure and sepsis. Domestic accidents were the leading mechanism (63%).

CONCLUSION

Burns were mostly due to accidents arising from carelessness, ignorance, hazardous traditions and improperly manufactured products. These can be prevented through mass education programs countrywide. Because almost all burn patients present to Emergency Departments first and not all hospitals can employ burn specialists, the patients with minor burns can be treated on an outpatient basis and the treatment of severe burns can be effectively initiated by emergency physicians.

Epidemiology of hospitalized burns patients in Taiwan

Previous studies based on either single hospital data or sampling of specific groups of hospitalized burns victims in Taiwan have provided only minimal epidemiological information. The study is designed to provide additional data on the epidemiology of hospitalized burns patients in Taiwan. Data were obtained from the Burn Injury Information System (BIIS), which brings together information supplied by 34 contracted hospitals. The study time course spanned a 2-year period from July 1997 to June 1999. Patient characteristics (age, sex, education level, etc.), causes and severity of injuries, and medical care measures were explored. A total of 4741 patients were registered with BIIS over the study period. The majority of hospitalized patients (67%) were male. The age distribution of burns patients showed peaks occurring at the age groups of 0-5 and 35-44 years. Over the time course of a day, burn injuries occurred more frequently from 10:00 to 12:00 h and 16:00 to 18:00 h. Injuries suspected as the result of suicide, homicide or child abuse accounted for 4.8% of hospitalized cases. More than 48% of the burns occurred in the home. The leading type of burn injury was scalding, followed by naked flame, explosion, electrical burns, and chemical burns due to caustic or corrosive substances. The mean percent total body surface area (%TBSA) for adults was 19%, and for young children was 12%. The average length of hospital stay was 18 days. In conclusion, children under 5 years and adults between 35 and 44 years of age are two high-risk groups for burn injuries. Corresponding to meal preparation time, hot substances such as boiling water, hot soup, etc. are the most common agents responsible for scalds. Prevention programs for reducing the risk of burn injuries during cooking and eating are required, especially for parents with young children.

Epidemiology of burns admitted to Ain Shams University Burns Unit, Cairo, Egypt

This study was prospectively carried out on 880 acutely burned patients admitted to the Burn Unit of Ain Shams University in Cairo, Egypt, during the period from the 1 May 1995 to the 31 October 2001, with the objective to analyze the epidemiological features of burned patients in our country. The means of age and percentage total body surface area burned (TBSB) were 27.8+/-2.9 years and 32+/-5.7%, respectively. Most of the patients were city dwellers and were self-referred to the Burn Unit. There were no significant yearly variations in hospital admissions. Seasonal variations in the form of peaks in winter and spring were noticed. Females (53.1%) were more prevalent than males (46.8%). Adults (61%) superceded children (39%). Male children (42.7%) population exceeded female children (35.8%). In contrast, adult females (64.1%) surpassed adult males (57.2%). The commonest burn location was home followed by outdoors then, work locations. Females were most commonly burned at home and mainly suffered from flame and scald burns. Males were most commonly burned in outdoor and work locations than at home and mainly sustained electric and flame burns. There was no difference in the mean percentage TBSB and burn depth in both sexes. Children were mostly burned at home and were mainly victims of scald and flame burns. They had lower rates of full thickness burns compared to adults. Adults were mostly burned in outdoor and work locations and mainly sustained flame and electrical injuries. The results of this study clearly highlighted the specific epidemiological features of burned patients in our area, and thus should provide the necessary information to develop proper burn prevention programs, thereby reducing the frequency of burns and burn-related deaths.

Mortality rates among 5321 patients with burns admitted to a burn unit in China: 1980-1998

A retrospective study was conducted on 5321 burn patients hospitalized in a burn center in Jinzhou, China during the period 1980-1998. Of the 5321 patients, 57.8% were between 15 and 44 years old and 3.4% were > or =60 years old. Ninety-six percent had burns covering less than half of body surface area and 31.7% had only full thickness skin burn. The number of patients in the 1990s was three times that of the 1980s. Overall mortality rate was 0.86%. LA(50) for total body burn area (TBSA) and only full thickness skin burn (FTSB) was 94 and 87%, respectively. The high survival rate, may relate primarily to the low percentages of older patients and of patients with severe burns. Inhalation injuries, infection and MOD are the main causes of deaths in our patients and would be key targets to improve clinical care and in future study.

Prevenção de queimaduras: percepção de pacientes e de seus familiares

Os objetivos deste estudo foram investigar os meios de prevenção de queimaduras identificados por pacientes vítimas de queimaduras e por seus familiares. Os dados foram coletados na Unidade de Queimados do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, mediante a realização de entrevistas com pacientes e seus familiares. Os dados foram categorizados por quatro juízes. Para verificar a existência de concordância entre os juízes, quanto à categorização, foi utilizada a medida não paramétrica de correlação - Coeficiente de Contingência. Foram entrevistados: 24 familiares de pacientes que sofreram queimaduras e 33 pacientes. Dos 33 pacientes entrevistados, 18 sofreram acidentes em ambiente doméstico. Dos 57 entrevistados, 11 afirmaram que não poderiam ter contribuído para evitar o acidente. Vinte pacientes e 12 familiares identificaram situações de risco no ambiente doméstico ou no trabalho, e 13 pacientes e 12 familiares não identificaram qualquer tipo de situação de risco. Os familiares e pacientes apontaram como medidas preventivas de acidentes por queimaduras: estar atento às atividades realizadas e ter cuidado com o manuseio de produtos inflamáveis.

Thermal Injury in the Elderly: When is Comfort Care the Right Choice?

The factors contributing to a higher mortality rate in elderly thermal injury victims are not well delineated. The purpose of this study is to determine the impact of the initial injury, medical comorbidities, and burn size on patient outcome and to determine a level of injury in this population when comfort care is an appropriate first choice. Individual medical records of patients over 65 years of age admitted to our burn center over a 10-year interval were reviewed for patient demographics, mechanism of injury, total body surface area (TBSA) burned, medical comorbidities, use of Swan-Ganz catheters, evidence of inhalation injury, level of support, and patient outcome. The mechanisms of thermal injury were flame (68%), scald (21%) and electrical or chemical contact (11%). Twenty-six preventable bathing, cooking, and smoking-related injuries were seen (33%). The average TBSA was 25 per cent. Average length of stay varied depending on outcome. The overall mortality rate for this group was 45 per cent. Patients older than 80 years with 40 per cent or greater TBSA burned had a 100 per cent mortality rate despite aggressive treatment. Burn wound size correlated better with probability of poor outcome than age. Thermal injuries in the elderly are becoming more important with the aging of our population. Underlying medical problems—specifically chronic obstructive pulmonary disease—do play a role in increased patient morbidity and mortality. This study shows that age greater than 80 years in combination with burns greater than 40 per cent TBSA are uniformly fatal despite aggressive therapy. We believe that delaying the start of comfort-only measures in this situation only prolongs the pain and suffering for the patient, the family, and the physician.

Epidemiological data and mortality rate of patients hospitalized with burns in Brazil

This retrospective analysis of burn patients in a University Hospital in the state of São Paulo, Brazil, was carried out to characterize this population and to identify the factors that affect the mortality rate. All patients hospitalized from January 1990 to April 1995 (n = 229, 3.6 patients/month) and who terminated treatment were included. Of these, 80.8% (185 patients) were hospitalized within 24 h of the burn. Occupational and/or domestic accidents were responsible for most of the burns (78.6%), which were mainly caused by a direct flame (71.2%). with alcohol being the flammable fluid most frequently used. The average patient treated at the center was a male of 9 years of age or less with 20-40% burned body surface, who received care within 24 h after suffering an accidental alcohol burn and who was hospitalized for < or =30 days. The mortality rate was 18.8% for all patients and increased with burned body surface and age, and for suicide patients. Suicide attempts for all patients > or = 18 years were the cause of 46 .5% (20/43) of the burns involving women and of 8.9% (8/90) of the burns involving men. The mortality rate was significantly higher for self-inflicted burns (42.9%) than for accidental burns (20.2%).
