Exhaust burns in children

Holiday hazards: burns in children during school holidays

BACKGROUND

Paediatric burns are preventable injuries that can have a permanent impact on a child's health and wellbeing. The Burns Unit at the Children's Hospital at Westmead appeared to experience an increase in paediatric burn injury referrals during the school holidays. The evaluation of the characteristics of burn injuries in the school holidays compared to the school term may improve the effectiveness of burn prevention programmes.

METHODS

A retrospective review was performed of all school-aged children who were referred to our institution between January 2005 and January 2019. Patient details, burn aetiology, burn severity, length of stay and need for grafting were compared between burns sustained during the school holidays and burns sustained during school term.

RESULTS

A total of 3020 children were referred to Children's Hospital at Westmead between January 2005 and January 2019. The mean number of burns sustained increased from 3.8 children per week during the school term to 5.4 children per week during school holidays (P < 0.0001). Contact burns were proportionally more common during school holidays than during the school term (26% versus 19.7%, P < 0.0001), whilst the proportion of scalds decreased significantly during the school holidays (43.5 versus 51.4%, P < 0.0001). There was no difference between mean age, % total body surface area, admission rates, length of stay or skin grafting rates.

CONCLUSION

There is a significant increase in burn injuries among school-aged children during the school holidays. This highlights the need for targeted education and prevention campaigns in the periods immediately preceding the school holidays.

The end of the assembly line: Shifting patterns of automotive burns

INTRODUCTION

As recently as 2006, carburetor flash burns comprised as much as 27% of admissions for car-related burns, despite the fact carburetors were last installed in pre-1990 automobiles. The prevalence of this injury pattern is related to the estimated 14 million cars on the road today that were manufactured prior to that year. The aim of this study was to investigate modern sources of automotive burns and describe any new trends in automotive burn-related epidemiology.

MATERIALS AND METHODS

A retrospective review was conducted of all burn admissions from the years 2009-2013 to identify patients who suffered automotive-related burns. Pediatric patients (<18 years old) were excluded. Demographic information including age, gender, mechanism of injury, occupation, TBSA, number of operations, and length of hospital stay were recorded.

RESULTS

From 2009-2013, the burn center saw 83 admissions for automotive-related burns. 14.5% of patients were mechanics. The most common injury pattern was from radiator burns (47%), followed by gasoline related burns (30%). There were only two carburetor burns (2.4%). 67.4% of patients were treated for less than two hospital days and there was one death (1.2% mortality).

CONCLUSION

Despite the removal of carburetors from engines and a decrease in this specific mechanism, a significant morbidity remains with gasoline-inflicted burns. More public awareness is needed for the safe removal of radiator caps and handling of chemicals in overheating engines.

Burn Injuries in Hospitalized Australian Children-An Epidemiological Profile

Globally, First Nations children sustain burns at a higher rate than other children. Little is understood about how health inequities contribute, especially from an Indigenous viewpoint. We analyzed data from the Burns Registry of Australian and New Zealand (BRANZ) for acute burns in children (<16 years) admitted to hospital between October 2009 and July 2018. Descriptive statistics examined equity variables in patient and injury characteristics. Poisson regression was used to describe factors associated with bacterial infection. Indigenous research methods were used throughout. Aboriginal and Torres Strait Islander children represented 10.4% of the study population. Health inequities were present for Aboriginal and Torres Strait Islander children with longer hospital length of stay (9.5 vs 4.6 days), rural residency (61.3% vs 13.9%), lower socioeconomic status (72.2% vs 34.9%), and more flame burns (19.5% vs 10.6%) compared to other Australian children. Streptococcus sp. infection risk was four times greater in Aboriginal and Torres Strait Islander children compared to other Australian children. Flame burns and high percentage total body surface area burns were a risk for Staphylococcus sp. and Streptococcus sp. infection in all children. The epidemiological profile for burn injuries managed in Australian burns centers differs between Aboriginal and Torres Strait Islander children and other children, indicating persistent health inequities. These differences should be considered in the development of injury prevention strategies and the clinical management of burn injuries for Aboriginal and Torres Strait Islander children and their families.

Characterization and analysis of exhaust pipe (muffler) contact burns: An unsuspecting culprit

Introduction

Thermal injury due to contact with engine exhaust systems represents a distinct subgroup of acute contact burns. Temperatures generated by motor vehicle, radiator, and lawn mower engines can exceed 250℃, at which point relatively deep tissue loss occurs with less than 0.06 seconds of cutaneous exposure. While prior studies have helped elucidate the demographic characteristics of exhaust pipe contact burns, our analysis was aimed at both demographics and burn severity, as indicated by rate of full-thickness injury and requirement for tangential excision and skin grafting.

Methods

Data were obtained from a retrospective review of admissions at a regional burn center between 1 July 2012 and 30 August 2016. Patients of all ages with muffler, exhaust, motorcycle, lawn mower, and radiator burn injuries were included. Extensive demographic information, percent total body surface area burned (TBSA), burn etiology and location, third-degree and fourth-degree burn percentage, and subsequent operative information were analyzed for patients who sustained exhaust pipe contact burns. These data were then compared with all contact burn injuries from the same time period, matched for %TBSA range, using Fisher exact and unpaired t-tests.

Results

A total of 110 patients suffered exhaust pipe contact burns during the study period; 65 (59%) were males, and mean age was 30. Nearly two thirds of the muffler burns were sustained from motorcycles with TBSA ranging from 0.05% to 3.14%; at least 61% had some third-degree burn. The average number of operating room visits per patient was 0.54, though this varied significantly, with 38 patients (35%) requiring 59 total surgeries (range 1–6). Muffler burn patients were older than the matched control group. The most common location of burn injury was the lower leg with no difference between adults and children. Pediatric patients understandably had smaller burn surface area but similar TBSA compared to adults. The majority of injuries occurred in May, June, and July.

Conclusions

Exhaust pipe contact burns comprise a specific subset of low %TBSA contact burns with relatively high morbidity, evidenced by a significantly higher proportion of full-thickness tissue loss and eventual need for skin grafting when compared with nonexhaust burn controls. Awareness of the increased severity of exhaust pipe contact burns may lead to more expedient surgical intervention as well as further education regarding preventative measures.

Rural and Metropolitan Pediatric Burns in New South Wales and the Australian Capital Territory: Does Distance Make a Difference?

To determine if differences exist between children who sustain burns in rural areas and in metropolitan areas, an analysis of children presenting to the Burns Unit at The Children's Hospital at Westmead, from the January 1, 2008 to December 31, 2012 was performed. In all, 4326 children met the inclusion criteria, of which 21.2% came from rural regions. Just more than a quarter (26.0%) of rural children and 11.6% from metropolitan areas were Indigenous Australian (P < 0.0001). The average age of rural child was 4.5 years; metropolitan child was 3.9 years (P = 0.0001). Boys were more likely to sustain burns in both populations. Of the rural children, 40.8% sustained contact burns, 37.7% scald, and 12.5% flame. In contrast, 58.8% metropolitan children sustained scalds, 27.4% contact, and 4.5% flame. The home was the most common place for all burns to occur, but rural injuries commonly occurred outdoors. Burns were associated with risk-taking behavior in 15.3% rural and 8.7% metropolitan children (P < 0.0001). Nearly two thirds (65.9%) of children in both groups received adequate first aid (20 minutes of cool running water). Major burn injuries (≥10% Total BSA) occurred in 3.4% of rural and 2.1% metropolitan children (P = 0.02). Skin grafting was required in 28.3% rural and 16.3% metropolitan children (P = 0.0001). Nearly 32% of rural children required admission to the Burns Unit for >24 hours (15.9% metropolitan; P = 0.0001). Significant differences exist between burns sustained by rural and metropolitan children. This should be accounted for in burns prevention campaigns and the education of local health practitioners.
