Preventable burns associated with the misuse of gasoline

Aetiology of bioethanol related burn accidents: A qualitative study

BACKGROUND

Since insight into the motivation of behaviour in bioethanol related burn accidents is lacking, this study aimed to qualitatively examine influencing factors in bioethanol related burn accidents. In order to identify target points for effective burn prevention.

METHODS

Patients previously admitted with bioethanol related acute non-intentional burn injury to the three Dutch burn centres were eligible. One interviewer conducted fourteen semi-structured interviews. Interviews were transcribed and coded by two independent researchers. Conclusions were drawn based on generalised statements on the concerned topics.

RESULTS

Four overall themes in influencing factors were found, namely 1) motivation; including non-designated use and impaired judgement, 2) knowledge and education; including unknown product and properties and information overload, 3) risk perception; including poor recognisability of risks and preferred trial and error and 4) thresholds; including easy availability and unclear liability.

CONCLUSION

Trust in consumers may be over-estimated, as proper use cannot be expected. To prevent future bioethanol related burn incidents, thresholds for obtaining and using bioethanol should be increased, safe alternatives to ignite open fires and wood stoves should be provided and knowledge and warnings should be improved.

Computational investigation of a 3D-printed skin substitute with orthotropy in mechanical property

As a promising treatment for third-degree burns, grafting with bioengineering skin substitutes shows a capability to overcome the deficiency of donor skin. Similar mechanical properties with human skin are required for employed skin substitutes to avoid secondary damage to patients. Given the representativeness of orthotropy in mechanical properties, there is a need for developing orthotropic skin substitutes. This paper presents computational investigation as well as structural design for the fabrication of orthotropic skin substitutes. A finite element method (FEM) based mechanics simulation model for analyzing the stress field in the skin substitute was developed, by which the stress distribution in mimetic structures of the epidermis and dermis can be acquired. Moreover, the equation of Young's modulus was deduced based on the simulation result, which expressed the mechanical property of designed skin substitutes. Furthermore, several structures of skin substitutes were proposed and their calculated Young's modulus ranged from 21.87 kPa to 213.32 kPa, which was similar to the human skin. Ultimately, uniaxial tensile tests were performed for three types of 3D-printed orthotropic skin substitutes, which validates the feasibility to regulate Young's modulus by regulating the structure of fabricated skin substitutes.

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.

Admission Carboxyhemoglobin: Is It a Marker for Burn Patient Outcomes?

BACKGROUND

Carbon monoxide is a gas produced by the combustion of hydrocarbon products that binds to heme molecules, 240 times more than oxygen, producing carboxyhemoglobin (COHb). As a result of its high affinity, there is shift of the oxyhemoglobin dissociation curve, compromising oxygen transport and delivery to tissues. Our study aim was to evaluate COHb elevation on admission as a predictor of worse outcomes in burn patients.

METHODS

This is a 10-year retrospective review of the American Burn Association Burn Registry from 2002 to 2011. We stratified the patients into 2 groups: adult patients with normal COHb on admission (group 1) versus elevated COHb (group 2). Elevated COHb levels were defined as greater than 10% on the first arterial blood gas. Outcome measures included in-hospital mortality rate, hospital length of stay (LOS), intensive care unit LOS (ICU-LOS), and ventilator days. χ and t test analyses were used with significance defined as a P value of less than 0.05.

RESULTS

A total of 6365 burn patients meet our inclusion criteria. There were 5775 patients in group 1 and 590 patients in group 2. Group 1 had an average age of 39.29 years compared with 42.62 years in group 2. The total body surface area was higher in group 1 compared with group 2 (6.24 vs 4.65) and with a statistically significant increase in partial thickness burns at 4.97 in group 1 compared with 3.27 in group 2. There was no statistically significant difference between the 2 groups in terms of full thickness total body surface area. The hospital LOS was significantly higher in group 2 compared with group 1 (15.34 vs 9.66). There was a significantly higher ICU-LOS at 12.89 days in group 2 compared with 4.01 in the group 1 (P = 0.0001, t test). There were higher ventilator days in group 2 at 9.23 than those in group 1 at 2.05 (P < 0.0001, t test). The in-hospital mortality was also significantly higher in group 2 at 15.59% than in group 1 at 1.33% (P = 0.0001, χ).

CONCLUSIONS

Elevated COHb on admission was associated with an increased hospital and ICU-LOS, average ventilator days, and in-hospital mortality. The presence of elevated COHb of greater than 10% on an initial arterial blood gas suggests worse outcomes and increased need of resource utilization during the index hospital admission.

Health status of rescued people by the NGO Open Arms in response to the refugee crisis in the Mediterranean Sea

Background

The migration over the Mediterranean has become one of the deadliest sea voyages in last few years. The NGO Open Arms works in the area since 2015, with the objectives of protecting and reporting human rights at sea. This paper aims to give an overview on characteristics and health conditions of rescued people by the NGO in the Central Mediterranean.

Methods

A descriptive retrospective population study was conducted, including people who were rescued from distress at sea by the NGO Open Arms from 1st July 2016 to 31st December 2018.

Results

In this period of time 22,234 people were rescued from sea. Among them 2234 (22.7%) were minors, and 177 (0.8%) pregnant women. The most frequent countries of origin were Nigeria (1278-13.1%), Eritrea (1215-12.3%) and Bangladesh (981-9.9%). Among all people rescued, 4516 (20.3%) reported symptoms. Scabies was the most frequent pathology, being suspected in 1817 (8.2%) people. Other infectious diseases were diagnosed in 91 (0.4%). Thirty-five (0.16%) patients suffered some complication from their chronic diseases. Acute injuries due to trauma, burns, aggressions, and bullet or bladed weapon wound were reported in 135 (0.6%) cases. Seventy-four corpses were recovered.

Conclusions

Main diagnoses on board were directly related to the precarious living conditions through migratory route, violence and complications of chronic diseases due to lack of care. The large number of people rescued highlights the catastrophic effect on migrants' health of European policies, which overlap the desire to restrict migratory movements on the humanitarian and health issues. An integrated information system and a coordinated response are basic to improve the situation in the area.

Accelerant-related burns and drug abuse: Challenging combination

BACKGROUND

Accelerants are flammable substances that may cause explosion when added to existing fires. The relationships between drug abuse and accelerant-related burns are not well elucidated in the literature. Of these burns, a portion is related to drug manufacturing, which have been shown to be associated with increased burn complications.

OBJECTIVES

1) To evaluate the demographics and clinical outcomes of accelerant-related burns in a Provincial Burn Centre. 2) To compare the clinical outcomes with a control group of non-accelerant related burns. 3) To analyze a subgroup of patients with history of drug abuse and drug manufacturing.

METHODS

Retrospective case control study. Patient data associated with accelerant-related burns from 2009 to 2014 were obtained from the British Columbia Burn Registry. These patients were compared with a control group of non-accelerant related burns. Clinical outcomes that were evaluated include inhalational injury, ICU length of stay, ventilator support, surgeries needed, and burn complications. Chi-square test was used to evaluate categorical data and Student's t-test was used to evaluate mean quantitative data with the p value set at 0.05. A logistic regression model was used to evaluate factors affecting burn complications.

RESULTS

Accelerant-related burns represented 28.2% of all burn admissions (N=532) from 2009 to 2014. The accelerant group had higher percentage of patients with history of drug abuse and was associated with higher TBSA burns, ventilator support, ICU stay and pneumonia rates compared to the non-accelerant group. Within the accelerant group, there was no difference in clinical outcomes amongst people with or without history of drug abuse. Four cases were associated with methamphetamine manufacturing, all of which underwent ICU stay and ventilator support.

CONCLUSIONS

Accelerant-related burns cause significant burden to the burn center. A significant proportion of these patients have history of drug abuse.

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.

Domestic bioethanol-fireplaces--a new source of severe burn accidents

BACKGROUND

Bioethanol-fueled fireplaces are popular interior home decoration accessories. Although their safety is promoted frequently, actual presentations of severe burn injuries in our burn intensive care unit (ICU) have focused the authors on safety problems with these devices. In this article we want to explore the mechanisms for these accidents and state our experiences with this increasingly relevant risk for severe burn injuries.

MATERIALS AND METHODS

The computerized medical records of all burn intensive care patients in our burn unit between 2000 and 2014 were studied. Since 2010, 12 patients with bioethanol associated burn injuries were identified. Their data was compared to the values of all patients, except the ones injured by bioethanol fireplaces that presented themselves to our burn ICU between the years 2010 and 2014.

RESULTS

At time of admission the bioethanol patients had a mean ABSI-score of 4.8 (+/- 2.2 standard deviation (SD)). A mean of 17 percent (+/- 9.1 SD) body surface area was burned. Involvement of face and hands was very common. An operative treatment was needed in 8 cases. A median of 20 days of hospitalization (range 3-121) and a median of 4.5 days on the ICU (range 1-64) were necessary. No patient died. In most cases the injuries happened while refilling or while starting the fire, even though safety instructions were followed. In the control group, consisting of 748 patients, the mean ABSI-score was 5.6 (+/- 2.7 SD). A mean of 16.5 percent (+/- 10.1 SD) body surface area was burned. Treatment required a median of 3 days on the burn ICU (range 1-120). Regarding these parameters, the burden of disease was comparable in both groups.

CONCLUSION

Bioethanol-fueled fireplaces for interior home decoration are a potential source for severe burn accidents even by intended use.

The Occurrence and Seasonal Variation of Accelerant-Related Burn Injuries in Central Florida

Accidental burn injuries result in significant economic and public health burdens. The inappropriate use of gasoline and other accelerants has been identified in many studies as dangerous, yet it remains an all-too-common practice resulting in a significant number of injuries annually. Florida's unique climate permits outdoor recreational and maintenance activities, such as burning yard debris and other trash, throughout the year. Additionally, the hurricane season, lasting from June 1 though November 30, produces large amounts of waste in its wake. The purpose of this study was to examine the seasonal pattern of occurrence and develop an understanding of factors related to accelerant-related burn injuries with the goal of prevention. This nonexperimental research involved a retrospective quantitative observational study of data stored in the National Trauma Registry database. All burn patients admitted to the Tampa General Regional Burn Center as inpatients between January 1, 2001, and December 31, 2005, were included. As with previous studies on the occurrence of accelerant related injuries, young men were much more likely to suffer this type of injury. The hurricane season correlates with an increased number of accelerant related burn injuries, which differs somewhat from the seasonal variations in other regions. The size and severity of accelerant-related injuries varies significantly, as does the length of hospital stay. Accelerant use is frequently associated with trash/brush-related accidents. Hurricane seasons can produce an inordinately large amount of debris and therefore are related with an increased incident in this type of burn injury. The results of this study support the development of a community-based educational program directed at burn injury prevention, with special attention to the implications of the hurricane season.

Ten-year Brisbane experience in petrol burns: a preventable health burden

Petrol is one of the most widely used and freely available fuels in use in developed countries today. This study examines the clinical details and demographics of adults with petrol burns over a 10-year period with a view to identifying any trends. The majority of petrol burns were due to human error and thus theoretically preventable. This study determined that the young male (aged 16-25) is most at risk, mainly through the misuse of petrol. The best method of prevention of these burns might be education targeting this group of population. This study provides a basis upon which effective intervention programmes can be designed.

Thermal injuries due to paint thinner

This study was designed to evaluate the epidemiology and outcome of burn injuries due to paint thinner in a local burn center. During a 10-year period, 32 patients were admitted to our Burn Unit for paint thinner thermal burn. Patients were reviewed regarding the age, sex, etiologic factors, extent and localization of burn, treatment methods, length of hospitalization, and results. There were 30 males and 2 females. The mean age of patients was 25.9 +/- 11 years. The most common etiologic factor was kindling a fire with paint thinner. The mean extent of burn was 33.6 +/- 24% of the total body surface area. All patients sustained burn injury on the face, arms, and hands and five patients among them had extended burn areas on the trunk and/or lower extremity. The mean length of hospitalization for the survivors was 34.5 +/- 21.6 days. Twenty-eight patients were treated by early excision and split-thickness skin grafting. In four patients, burn wounds were healed by conservative management. Five patients with burn size of over 75% of the total body surface area died. In conclusion, paint thinner may be the cause of a catastrophic thermal injury and should not be used for the purpose of kindling fire.

Trash and brush burning: an underappreciated mechanism of thermal injury in a rural community

Open-fire injuries associated with burning trash or brush result in a significant number of burn admissions annually. Trash- and brush-burning injuries are more prevalent in rural environments where open burning is an acceptable practice of waste disposal. These injuries are not "unavoidable accidents" but follow a predictable injury pattern. Understanding this injury pattern is paramount to effective prevention. The purpose of this work is to describe the epidemiology of burn injuries associated with burning trash or brush. Charts were retrospectively reviewed for all trash and brush burning injuries from July 1989 to December 2000. One hundred ninety-four injuries were identified, accounting for one fifth of all flame admissions for the study period. Persons most at risk for these burn injuries were males between the ages of 25 to 45, followed by males ages 16 to 24. Accelerant use was identified in over 80% of these injuries. The median cost for admission was $9,363.00 US dollars. Cost was significantly related to age, percent body surface area burned, and operative intervention. Brush and trash burning can lead to costly injuries especially when accelerants are used. Additional research is needed to explore the cultural and social influences associated with these injuries to target effective prevention.
