Five-year epidemiology of liquefied petroleum gas-related burns

The epidemiology of alcohol burns at a major burn centre in North China

This study was designed to explore the epidemiological characteristics and potential preventive strategies of alcohol burns. In this five-year, retrospective study, 163 patients with alcohol burns (admitted from 1 January 2015 to 31 May 2020 were included. There was a male-to-female ratio of 1.1:1, a mean age of 34.1±16.8 years, and a mean burn size of 13.3±13.7% total body surface area (TBSA). The number of patients with alcohol burns was similar year by year during the five-year period. Just over half of patients (n=84, 51.5%) sustained a third-degree burn injury, which was significantly associated with a longer hospital stay and the need for surgery. The most prevalent aetiology was cupping (n=49, 29.5%), followed by cooking hotpot (n=37, 22.7%). Of the patients, seven (4.29%) sustained injuries during experiments at school and one patient sustained injury when using alcohol spray for disinfection against COVID-19. The incidence of facial burn injury (n=105, 64.4%) was significantly higher than previously reported data (33.2%). The result of the study showed that cupping and hotpot were the main causes of alcohol burns in Beijing, which should be taken into consideration for prevention. It is necessary to strengthen safety management of classes at school where experiments are undertaken and to educate the general public on the proper means of disinfecting against COVID-19.

Epidemiology and Outcomes of Cooking- and Cookstove-Related Burn Injuries: A World Health Organization Global Burn Registry Report

Cooking- and cookstove-related burns (CSBs) comprise a large proportion of burn injuries globally, but there are limited data on cooking behavior patterns to inform prevention and advocacy. Therefore, we aimed to describe the epidemiology, risk factors, and outcomes of these injuries and highlight the potential of the World Health Organization (WHO) Global Burn Registry (GBR). Patients with cooking-related burns were identified in the WHO GBR. Patient demographics, cooking arrangement, injury characteristics, and outcomes were described and compared. Bivariate regression was performed to identify risk factors associated with CSBs. Analysis demonstrated that 25% of patients in the GBR sustained cooking-related burns (n = 1723). The cooking environment and cooking fuels used varied significantly by country income level ([electricity use: LIC 1.6 vs MIC 5.9 vs HIC 49.6%; P < .001] [kerosene use: LIC 5.7 vs MIC 10.4 vs HIC 0.0%; P < .001]). Of cooking-related burns, 22% were cookstove-related burns (CSBs; 311 burns). Patients with CSBs were more often female (65% vs 53%; P < .001). CSBs were significantly larger in TBSA size (30%, IQR 15-45 vs 15%, IQR 10-25; P < .001), had higher revised Baux scores (70, IQR 46-95 vs 28, IQR 10-25; P < .001) and more often resulted in death (41 vs 11%; P < .001) than other cooking burns. Patients with CSBs were more likely to be burned by fires (OR 4.74; 95% CI 2.99-7.54) and explosions (OR 2.91, 95% CI 2.03-4.18) than other cooking injuries. Kerosene had the highest odds of CSB compared to other cooking fuels (OR 2.37, 95% CI 1.52-3.69). In conclusion, CSBs specifically have different epidemiology than cooking-related burns. CSBs were more likely caused by structural factors (eg, explosion, fire) than behavioral factors (eg, accidental movements) when compared to other cooking burns. These differences suggest prevention interventions for CSBs may require distinctive efforts than typically deployed for cooking-related injuries, and necessarily involve cookstove design and safety regulations to prevent fires and explosions.

Epidemiology and Early Bacteriology of Extremely Severe Burns from an LPG Tanker Explosion in Eastern China

The incidence of liquefied petroleum gas (LPG)-related accidents in China has increased over the recent years. In addition, infection remains a big challenge in cases of severe burns. Therefore, the present study aimed to provide valuable information for a better control of infections in the event of such disasters. In this study, a total of 16 patients who suffered extremely severe burns after an LPG tanker explosion were included. Thereafter, bacteriological culture results were collected within a week. Of 16 patients, 13 (81.25%) were male and the average age of all patients was 60.63 years. In addition, the mean burned area was 83.03% TBSA. Additionally, a total of 553 organism cultures were conducted out of which 287 isolates (51.90%) showed positive results. Notably, 38.52% were Gram-negative bacteria, 7.59% were Gram-positive bacteria and 5.79% were fungi. Moreover, the most prevalent Gram-negative bacteria were Stenotrophomonas maltophilia (28.97%) followed by Acinetobacter baumannii (28.53%), and Klebsiella pneumoniae (14.02%). On the other hand, the three most predominant Gram-positive bacteria were Enterococcus faecalis (33.33%), Staphylococcus aureus (28.89%) and Staphylococcus sciuri (17.78%). Furthermore, the most common fungi included Candida (38.24%), Fusarium (20.59%) and Aspergillus fumigatus (14.71%). With regard to the bacterial resistance patterns, carbapenem-resistant organisms included Acinetobacter baumannii (97.80%), Pseudomonas aeruginosa (67.57%), and Klebsiella pneumoniae (75.56%). In addition, Staphylococcus sciuri, Staphylococcus epidermidis, and Staphylococcus haemolyticus were identified to be methicillin-resistant. This study revealed that there was a high incidence of infection in victims of severe burns as a result of mass burn accidents, accompanied by early fungal infection.

Management of severe burn injuries with novel treatment techniques including maggot debridement and applications of acellular fish skin grafts and autologous skin cell suspension in a dog

CASE DESCRIPTION

A 3-year-old 27-kg female spayed American Bulldog with severe burn injuries caused by a gasoline can explosion was evaluated.

CLINICAL FINDINGS

The dog had extensive partial- and full-thickness burns with 50% of total body surface area affected. The burns involved the dorsum extending from the tail to approximately the 10th thoracic vertebra, left pelvic limb (involving 360° burns from the hip region to the tarsus), inguinal area bilaterally, right medial aspect of the thigh, and entire perineal region. Additional burns affected the margins of the pinnae and periocular regions, with severe corneal involvement bilaterally.

TREATMENT AND OUTCOME

The dog was hospitalized in the hospital's intensive care unit for 78 days. Case management involved provision of aggressive multimodal analgesia, systemic support, and a combination of novel debridement and reconstructive techniques. Debridement was facilitated by traditional surgical techniques in combination with maggot treatment. Reconstructive surgeries involved 6 staged procedures along with the use of novel treatments including applications of widespread acellular fish (cod) skin graft and autologous skin cell suspension.

CLINICAL RELEVANCE

The outcome for the dog of the present report highlighted the successful use of maggot treatment and applications of acellular cod skin and autologous skin cell suspension along with aggressive systemic management and long-term multimodal analgesia with debridement and wound reconstruction for management of severe burn injuries encompassing 50% of an animal's total body surface area.

Etiological & clinical spectrum of Liquefied Petroleum Gas (LPG) related burns: A three-year study from a tertiary care burn centre in New Delhi

Burns, an endemic public health problem has had a dynamic epidemiology in India, in sync with economic and social changes. In the last decade a major shift of kitchen fuel usage from kerosene to the Liquefied Petroleum Gas has resulted in an increase in the incidence of burns from LPG mishaps. This prospective descriptive study conducted in a tertiary care burn centre in an urban area aims to determine the causes of LPG related burns, its injury profile, identify the population at risk and also to determine the level of knowledge of users regarding the safety issue with LPG usage. In the study LPG burns accounted for 52.3% of the admitted flame burns. On the whole there were 33 incidents of LPG mishaps involving multiple victims. Most common age group affected was 26-50 years. Leakage from larger cylinders was more common and malfunction of valve/regulator was the most common cause. Level of knowledge was dismally low across all socioeconomic strata. Our study highlights impact of changing socioeconomic pattern of the country on burns epidemiology and the glaring lack of public awareness regarding safe management principles.

Acute Management of Thermal Hand Burns in Adults: A 10-Year Review of the Literature

INTRODUCTION

Advances in the evidence base of acute thermal hand burns help to guide the management of these common injuries. The aim of this literature review was to evaluate recent evidence in the field over 10 years.

METHODS

The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols methodology was used as a guide for this literature review. PubMed, MEDLINE, EMBASE, CINAHL, and Google Scholar were searched for English language articles related to hand burns published between 2009 and 2018 inclusive, and the Cochrane Library was reviewed. Exclusion criteria were as follows: participants younger than 18 years, scar or contracture management, rehabilitation, outcomes assessment, late reconstruction, and electrical or chemical burns.

RESULTS

An initial search retrieved 6493 articles, which was narrowed to 403 full-text articles that were reviewed independently by 3 of the authors and categorized. Of 202 included articles, there were 8 randomized controlled trials and 2 systematic reviews. Six evidence-based guidelines were reviewed. Referral of hand burns to specialist centers, use of telemedicine, early excision and grafting, and immediate static splintage have been recommended. Enzymatic debridement results in earlier intervention, more accurate burn assessment, preservation of vital tissue, and fewer skin grafts, and ideally requires regional anesthesia. Guidance on escharotomy emphasizes indication, technique and adequate intervention, and potential for enzymatic debridement. Inclusion of topical negative pressure, dermal regenerative templates, acellular dermal matrices, and noncellular skin substitutes in management has helped improve scar and functional outcomes.

DISCUSSION

The results of this literature review demonstrate that multiple national and international societies have published burns guidelines during the decade studied, with aspects directly relevant to hand burns, including the International Society for Burn Injuries guidelines. There are opportunities for evidence-based quality improvement across the field of hand burns in many centers.

CONCLUSIONS

More than 200 articles globally in 10 years outline advances in the understanding of acute management of thermal hand burns. Incorporating the evidence base into practice may facilitate optimization of triage referral pathways and acute management for hand burns.

A Retrospective Multicenter Study of 1898 Liquefied Petroleum Gas-Related Burn Patients in Eastern China From 2011 to 2015

Liquefied petroleum gas (LPG) is a widely used environment-friendly fuel. Previous studies have shown an increasing number of LPG-related burns. Our study was designed to evaluate the epidemiologic pattern of these injuries and provide recommendations for burn prevention. This retrospective study included all patients with LPG-related burns from eight burn centers in Zhejiang Province, China between 2011 and 2015. Database variables included patient demographics, accident characteristics, and injury characteristics. The association between different categorical variables was identified using the chi-square test. And the association between two or more means of quantitative variables was analyzed by the one-way analysis of variance or t-test. A total of 1898 patients were included, 47.31% were males and 52.69% were females. The predominant age group was 31 to 70 years (74.50%), and the majority were poorly educated and the incidence peaked from June to September. The most common place of occurrence was home (74.08%) and gas leak (96.52%) was the most common cause. The four limbs (43.33%) were the most frequently affected areas; the mean burn area was 25.19 ± 20.97% of the total body surface area and most patients (46.89%) suffered from moderate burns. The mean length of hospital stay was 17.66 ± 16.55 days and the majority of patients (89.36%) recovered with a 0.84% mortality rate. Our findings reflected that the increase in incidence rate was alarming, and the causes resulting in LPG-related burns have not gained much attention yet. Therefore, this calls for simple but strict measures aiming at each hazardous step during the use of LPG to prevent these burn injuries.

Burn injury

Burn injuries are under-appreciated injuries that are associated with substantial morbidity and mortality. Burn injuries, particularly severe burns, are accompanied by an immune and inflammatory response, metabolic changes and distributive shock that can be challenging to manage and can lead to multiple organ failure. Of great importance is that the injury affects not only the physical health, but also the mental health and quality of life of the patient. Accordingly, patients with burn injury cannot be considered recovered when the wounds have healed; instead, burn injury leads to long-term profound alterations that must be addressed to optimize quality of life. Burn care providers are, therefore, faced with a plethora of challenges including acute and critical care management, long-term care and rehabilitation. The aim of this Primer is not only to give an overview and update about burn care, but also to raise awareness of the ongoing challenges and stigmata associated with burn injuries.
