Laryngotracheal stenosis post mechanical ventilation in paediatric burns patients.

INTRODUCTION: The duration of endotracheal intubation is thought to be the most important factor in the development of acquired laryngotracheal stenosis (LTS); however, there is a paucity of studies examining the incidence of LTS in the paediatric burn population. The aim of this study was to determine the incidence of LTS in paediatric burns patients requiring mechanical ventilation to develop guidelines for consideration of a tracheostomy. METHODS: A retrospective review of all children treated at The Children's Hospital at Westmead (CHW) Burns Unit (BU) from December 2009 to December 2019 who required intubation for their burn injury. RESULTS: During the 10-year study period 115 patients required endotracheal intubation after having sustained a burn injury. Of these 11 were excluded. The mean age was 6.2 years (0-16), with the majority of patients being male (65%). The average TBSA was 18.5% with a range of 0.1-70%. Flame was the most common mechanism of burn (n = 59). Burns to the head and/or neck were the most common indication for intubation with the mean duration of intubation 6.1 days (range 0-40). Tracheostomies were performed on two patients (1.9%). LTS was found in two patients (1.9%). CONCLUSION: LTS in the paediatric burn population post mechanical ventilation appears to be a rare event. Endotracheal intubation can safely be used as the route of airway access in paediatric burns patients. Based on our experience, a definitive recommendation on the timing of tracheostomy in the paediatric burn patient cannot be made.

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.

Too Hot to Handle? Full-Thickness Burn Injury in a Child Caused by Cyanoacrylate Glue and Cotton-A Case Report and Experimental Study.

Domestic superglue (cyanoacrylate) in the hands of children can have devastating consequences, especially when cotton clothing is involved. When cotton comes into contact with cyanoacrylate, an intense exothermic reaction occurs, creating temperatures high enough to cause significant thermal injury. A literature review found 16 such cases of burns documented (2 adult and 14 pediatric). This article presents a case report of a 4-year-old child sustaining a full-thickness burn injury to her leg requiring skin grafting when superglue was spilt onto cotton pants. She was sitting near a fan heater at the time. An experiment was conducted to replicate the exothermic reaction between superglue and cotton and to determine if the addition of radiant heat would have any significant effect. The maximum temperature reached with one 3-g tube of superglue onto cotton pyjamas was 91°C (196°F) and occurred approximately 90 seconds postapplication. It took more than 3 minutes for the temperature to cool below 40°C (104°F). The addition of radiant heat from a fan heater placed 60 cm from the clothing found that the temperature peak was similarly reached and cooled, but the temperature did not reduce below 52°C (126°F) for over 20 minutes, proving that potential harm may be amplified if first aid is not appropriately sought. Product labeling and the knowledge of potential harm from such mechanism of injury remain inadequate. It is hoped that the reporting of this case contributes to an increase in public education and awareness of such dangers and may contribute to preventing avoidable future incidences.

Assessment and management of minor burns in children.

BACKGROUND: Approximately 1% of the Australian and New Zealand population seeks medical assistance for a burn injury each year, and many patients presenting with burns are children. Minor burns that do not meet referral criteria can be managed by the family general practitioner (GP). If there are any concerns about the injury or progress of the burn wound healing, GPs are encouraged to contact their local burns service for advice. OBJECTIVE: The aim of this article is to provide primary healthcare clinicians with a summary of the acute management of minor burns in children. DISCUSSION: Effective first aid for burns will minimise burn progression and alleviate pain. Appropriate wound care will promote optimal healing and potentiate favourable outcomes. Although a minor burn may not meet initial referral criteria for transfer to a specialised burn centre, GPs are encouraged to refer if there are any concerns in relation to wound healing, pain management or scarring, or if consultative advice regarding management is required.

Subspecialty approach for the management of acute cholecystitis: an alternative to acute surgical unit model of care.

BACKGROUND: Acute cholecystitis is a common condition. Recent studies have shown an association between creation of an acute surgical unit (ASU) and improved outcomes. This study aimed to evaluate the outcomes of a subspecialty based approach to the management of acute cholecystitis as an alternative to the traditional 'generalist' general surgery approach or the ASU model. METHOD: A 6-year retrospective analysis of outcomes in patients admitted under a dedicated upper gastrointestinal service for acute cholecystitis undergoing emergency laparoscopic cholecystectomy. RESULTS: Seven hundred emergency laparoscopic cholecystectomies were performed over this time. A total of 486 patients were available for analysis. The median time to operation was 2 days and median length of operation was 80 min. A total of 86.9% were performed during daylight hours. Eight cases were converted to open surgery (1.6%). Intra-operative cholangiography was performed in 408 patients. The major complication rate was 8.2%, including retained common bile duct stones (2.3%), sepsis (0.2%), post-operative bleeding (0.4%), readmission (0.6%), bile leak (2.1%), AMI (0.4%), unscheduled return to theatre (0.6%) and pneumonia (0.8%). There were no mortalities and no common bile duct injuries. CONCLUSION: Over a time period that encompasses the current publications on the ASU model, a subspecialty model of care has shown consistent results that exceed established benchmarks. Subspecialty management of complex elective pathologies has become the norm in general surgery and this study generates the hypothesis that subspecialty management of patients with complex emergency pathologies should be considered a valid alternative to ASU. Access block to emergency theatres delays treatment and prolongs hospital stay.
