An international RAND/UCLA expert panel to determine the optimal diagnosis and management of burn inhalation injury.

BACKGROUND: Burn inhalation injury (BII) is a major cause of burn-related mortality and morbidity. Despite published practice guidelines, no consensus exists for the best strategies regarding diagnosis and management of BII. A modified DELPHI study using the RAND/UCLA (University of California, Los Angeles) Appropriateness Method (RAM) systematically analysed the opinions of an expert panel. Expert opinion was combined with available evidence to determine what constitutes appropriate and inappropriate judgement in the diagnosis and management of BII. METHODS: A 15-person multidisciplinary panel comprised anaesthetists, intensivists and plastic surgeons involved in the clinical management of major burn patients adopted a modified Delphi approach using the RAM method. They rated the appropriateness of statements describing diagnostic and management options for BII on a Likert scale. A modified final survey comprising 140 statements was completed, subdivided into history and physical examination (20), investigations (39), airway management (5), systemic toxicity (23), invasive mechanical ventilation (29) and pharmacotherapy (24). Median appropriateness ratings and the disagreement index (DI) were calculated to classify statements as appropriate, uncertain, or inappropriate. RESULTS: Of 140 statements, 74 were rated as appropriate, 40 as uncertain and 26 as inappropriate. Initial intubation with ≥ 8.0 mm endotracheal tubes, lung protective ventilatory strategies, initial bronchoscopic lavage, serial bronchoscopic lavage for severe BII, nebulised heparin and salbutamol administration for moderate-severe BII and N-acetylcysteine for moderate BII were rated appropriate. Non-protective ventilatory strategies, high-frequency oscillatory ventilation, high-frequency percussive ventilation, prophylactic systemic antibiotics and corticosteroids were rated inappropriate. Experts disagreed (DI ≥ 1) on six statements, classified uncertain: the use of flexible fiberoptic bronchoscopy to guide fluid requirements (DI = 1.52), intubation with endotracheal tubes of internal diameter < 8.0 mm (DI = 1.19), use of airway pressure release ventilation modality (DI = 1.19) and nebulised 5000IU heparin, N-acetylcysteine and salbutamol for mild BII (DI = 1.52, 1.70, 1.36, respectively). CONCLUSIONS: Burns experts mostly agreed on appropriate and inappropriate diagnostic and management criteria of BII as in published guidance. Uncertainty exists as to the optimal diagnosis and management of differing grades of severity of BII. Future research should investigate the accuracy of bronchoscopic grading of BII, the value of bronchial lavage in differing severity groups and the effectiveness of nebulised therapies in different severities of BII.

Surgical Repair of the Acute Burn Wound: Who, When, What Techniques? What Is the Future?

Modern burns surgery is multidisciplinary, multimodal and includes a dermal preservation approach. The management of the surgical wound starts in the pre-hospital environment with stabilization and assessment of the burn injured patient according to protocols of trauma resuscitation with special emphasis in the assessment of the burn depth and surface area. A large burn requires fluid resuscitation and physiological support, including counterbalancing hyper metabolism, fighting infection and starting a long burns intensive care journey. A deep burn may impose the need for surgical debridement and cover through a staged approach of excision of devitalized tissue depending on its extension and patient circumstances. These methodologies warrant patients survivability and require professionals integrated in a multidisciplinary team sharing decisions and directing management. Burns Multimodality involves multiple techniques used according to patient's needs, wound environment, operators experience and available resources. Traditional practices used together with new techniques may reduce morbidity and operative time but also challenge stablished practice. The concept of using the best teams with the best techniques combines with the need for selective and judicious surgery that preserves tissue architecture and spares as much as possible dermal component, therefore reducing the possibility of functional impairment and cosmetic embarrassment caused by pathological scars. Who is best placed to perform these tasks, the appropriate or best timing of surgery and the different practices used to achieve best results will be discussed, together with a reflection on what the future holds for these fundamental steps in the management of the burn injured patient turning into a functional burn survivor.

The use of human deceased donor skin allograft in burn care.

Burns are tissue wounds caused by thermal, electrical, chemical cold or radiation injuries. Deep injuries lead to dermal damage that impairs the ability of the skin to heal and regenerate on its own. Skin autografting following burn excision is considered the current gold standard of care, but lack of patient's own donor skin or unsuitability of the wound for autografting may require the temporary use of dressings or skin substitutes to promote wound healing, reduce pain, and prevent infection and abnormal scarring. These alternatives include deceased donor skin allograft, xenograft, cultured epithelial cells and biosynthetic skin substitutes. Allotransplantation is the transplantation of cells, tissues, or organs, sourced from a genetically non-identical member of the same species as the recipient. Human deceased donor skin allografts represent a suitable and much used temporizing option for skin cover following burn injury. The main advantages for its use include dermoprotection and promotion of reepithelialisation of the wound and their ability to act as skin cover until autografting is possible or re-harvesting of donor sites becomes available. Disadvantages of its use include the limited abundance and availability of donors, possible transmission of disease, the eventual rejection by the host and its handling storing, transporting and associated costs of provision. This paper will explore the role of allograft skin in burn care, defining the indications for its use in burn management and the future potential for allograft tissue banking.

In hot water: The impact of burn injuries from hot water bottles - Experience of a UK burns unit and review of the literature.

INTRODUCTION: Hot water bottles (HWBs) are a common domestic item in the UK. Their use is associated with burns injuries, either by contact for prolonged periods with the skin, or through the HWB leaking or bursting. METHODS: We used electronic health records to retrospectively review HWB related burns treated by the Burns Service at Chelsea and Westminster Hospital between January 2017-March 2018. We analysed the mechanism of injury, size and depth of burn, method of treatment and costs associated with HWB burns in our centre. RESULTS: 80 patients sustained HWB burns during this period, with a similar incidence of contact burns (41/80, 51.3%) and scalds (38/80, 47.5%), with one steam burn. The commonest area burnt was the lower limb (40/80, 50%). Most burns had a TBSA of 1% or smaller (50/80, 62.5%). 30 patients had full thickness burns, with 37 in total received operative management. We estimate that the total cost for managing this cohort of patients was over £68,634. CONCLUSIONS: There are a significant proportion of patients presenting with HWB burns that could be prevented, with significant impact on patient morbidity and resource burden on the NHS. Targeted public awareness campaigns are needed to ameliorate these injuries.

Implementation of a checklist to enhance operation note quality at a UK burns centre.

INTRODUCTION: Operation notes are fundamental for clinical, academic and medico-legal purposes. Good Surgical Practice (2014) provides guidelines to assist note completion but the literature suggests poor adherence to these. The aim of this study was to evaluate and improve operation note quality at a UK burns centre through implementation of a burns surgery-specific checklist. METHODS: A 22-component burns surgery-specific checklist, modified from Good Surgical Practice (2014), was designed and implemented. The quality of 80 operation notes (40 pre and 40 post-implementation) was assessed against this checklist. Fisher's exact and Mann-Whitney U statistical tests were used to evaluate pre and post-intervention note quality. RESULTS: Before checklist implementation, only 6/22 components (27.3%) were recorded on every note. 4/22 components (18.2%) were not recorded on any, including microbiology specimen and clinical photography, which are particularly important in burns. After implementation, 16/22 (72.7%) were recorded on every note, with a statistically significant improvement in all other components (p≤0.01), except venous thromboembolism prophylaxis (p=0.10). The median percentage score of components recorded improved from 78.2 to 100% (p<0.01). CONCLUSION: To our knowledge, this is the first study in available literature to show that a burns surgery-specific checklist can significantly improve burns operation note quality. This presents a simple and cheap method to improve note quality and may enhance post-operative intra/inter-team communication and patient care. At our unit, we have now developed an electronic checklist format with mandatory field completion to facilitate total compliance.

Operating efficiency of an emergency Burns theatre: An eight month analysis.

BACKGROUND: The efficient use of operating theatres is important to insure optimum cost-benefit for the hospital. We used the emergency Burns theatre as a model to assess theatre efficiency at our institution. METHODS: Data was collected retrospectively on every operation performed in the Burns theatre between 01/04/15 and 30/11/15. Each component of the operating theatre process was considered and integrated to calculate values for surgical/anaesthetic time, changeover time and ultimately theatre efficiency. RESULTS: A total of 426 operations were carried out over 887h of allocated theatre time (ATT). Actual operating time represented 67.7%, anaesthetic time 8.8% and changeover time 14.2% of ATT. The average changeover time between patients was 30.1min. Lists started on average 27.7min late each day. There were a total of 5.8h of overruns and 9.6h of no useful activity. Operating theatre efficiency was 69.3% for the 8 month period. CONCLUSION: Our study highlights areas where theatre efficiency can be improved. We suggest various strategies to improve this that may be applied universally.

An analysis of surgical and anaesthetic factors affecting skin graft viability in patients admitted to a Burns Intensive Care Unit.

OBJECTIVES: Skin graft failure is a recognised complication in the treatment of major burns. Little research to date has analysed the impact of the complex physiological management of burns patients on the success of skin grafting. We analysed surgical and anaesthetic variables to identify factors contributing to graft failure. METHODS: Inclusion criteria were admission to our Burns Intensive Care Unit (BICU) between January 2009 and October 2013 with a major burn. After exclusion for death before hospital discharge or prior skin graft at a different hospital, 35 patients remained and were divided into those with successful autografts (n=16) and those with a failed autograft (n=19). For the purposes of this study, we defined poor autograft viability as requiring at least one additional skin graft to the same site. Logistic regression of variables was performed using SPSS (Version 22.0 IBMTM). RESULTS: Age, Sex, %Total Burn Surface Area or Belgian Outcome Burns Injury score did not significantly differ between groups. No differences were found in any surgical factor at logistic regression (graft site, harvest site, infection etc.). When all operations were analysed, the use of colloids was found to be significantly associated with graft failure (p=0.035, CI 95%) and this remained significant when only split thickness skin grafts (STSGs) and debridement operations were included (p=0.034, CI 95%). No differences were found in crystalloid use, intraoperative temperature, pre-operative haemoglobin and blood products or vasopressor use. CONCLUSIONS: This analysis highlights an independent association between colloids and graft failure which has not been previously documented.

Revised Baux Score and updated Charlson comorbidity index are independently associated with mortality in burns intensive care patients.

PURPOSE: The purpose of the current study was to utilise established scoring systems to analyse the association of (i) burn injury severity, (ii) comorbid status and (iii) associated systemic physiological disturbance with inpatient mortality in patients with severe burn injuries admitted to intensive care. METHODS: Case notes of all patients with acute thermal injuries affecting ≥15% total body surface area (TBSA) admitted to the Burns Intensive Care Unit (BICU) at Chelsea and Westminster Hospital during a 10-year period were retrospectively reviewed. Revised Baux Score, Belgian Outcome in Burn Injury (BOBI) Score, Abbreviated Burn Severity Index (ABSI), APACHE II Score, Sequential Organ Failure Assessment (SOFA) Score and Updated Charlson Comorbidity Index (CCI) were computed for each patient and analysed for association with inpatient mortality. RESULTS: Ninety mechanically ventilated patients (median age 45.7 years, median % TBSA burned 36.5%) were included. 72 patients had full thickness burns and 35 patients had inhalational injuries. Forty-four patients died in hospital while 46 survived to discharge. In a multivariate logistic regression model, only the Revised Baux Score (p<0.001) and updated CCI (p=0.014) were independently associated with mortality. This gave a ROC curve with area under the curve of 0.920. On multivariate cox regression survival analysis, only the Revised Baux Score (p<0.001) and the updated CCI (p=0.004) were independently associated with shorter time to death. CONCLUSION: Our data suggest that the Revised Baux Score and the updated CCI are independently associated with inpatient mortality in patients admitted to intensive care with burn injuries affecting ≥15% TBSA. This emphasises the importance of comorbidities in the prognosis of patients with severe burn injuries.

Toxic epidermal necrolysis (TEN): the Chelsea and Westminster Hospital wound management algorithm.

Toxic epidermal necrolysis syndrome (TEN) is a potentially catastrophic exfoliative muco-cutaneous disorder first described by Lyell in 1956. It represents the most extensive form of Steven-Johnson syndrome. TEN is defined varyingly around the globe, but in the United Kingdom the consensus opinion describes the process as involving >30% of the total body surface area. It can rapidly become more extensive and threatens life. The estimated annual incidence is approximately 1-2 cases per million population. The risk of mortality increases with surface area involved and meta-analysis of the literature shows this risk to be between 16% and 55%. Over a six month period the Chelsea and Westminster Hospital Burns Service treated five consecutive patients with more than 80% total body surface area involvement or a more than 80% mortality risk, using the severity-of-illness score for toxic epidermal necrolysis (SCORTEN). All patients were treated according to the Chelsea and Westminster Hospital wound management algorithm with excellent outcome and no mortalities. The aim of this paper is to propose a generic TEN wound management algorithm according to the severity of skin lesions, using a simple wound grading system.

The quality of video information on burn first aid available on YouTube.

AIM: To evaluate the clinical accuracy and delivery of information on thermal burn first aid available on the leading video-streaming website, YouTube. METHODOLOGY: YouTube was searched using four separate search terms. The first 20 videos identified for each search term were included in the study if their primary focus was on thermal burn first aid. Videos were scored by two independent reviewers using a standardised scoring system and the scores totalled to give each video an overall score out of 20. RESULTS: A total of 47 videos were analysed. The average video score was 8.5 out of a possible 20. No videos scored full-marks. A low correlation was found between the score given by the independent reviewers and the number of views the video received per month (Spearman's rank correlation co-efficient=0.03, p=0.86). CONCLUSION: The current standard of videos covering thermal burn first aid available on YouTube is unsatisfactory. In addition to this, viewers do not appear to be drawn to videos of higher quality. Organisations involved in managing burns and providing first aid care should be encouraged to produce clear, structured videos that can be made available on leading video streaming websites.

Burn to leg: full thickness lower limb burn associated with laptop power adaptor.

There has been much media attention in recent years on laptops and their accessories overheating and even causing fires. Here, the authors report a case of a laptop power adaptor causing a full thickness burn requiring surgical intervention in a young, fit man. The total contact time was less than 1 h. Initial surgical management involved debridement and allografting of the wound due to a concomitant cellulitis. A week later, once the cellulitis had resolved, an autograft was applied. The graft take was satisfactory (100%) and the patient had a good postoperative outcome.

Topical management of facial burns.

The face is the central point of the physical features of the human being. It transmits expressions and emotions, communicates feelings and allows for individual identity. It contains complex musculature and a pliable and unique skin envelope that reacts to the environment through a vast network of nerve endings. The face hosts vital areas that make phonation, feeding, and vision possible. Facial burns disrupt these anatomical and functional structures creating pain, deformity, swelling, and contractures that may lead to lasting physical and psychological sequelae. The management of facial burns may include operative and non-operative treatment or both, depending on the depth and extent of the burn. This paper intends to provide a review of the available options for topical management of facial burns. Topical agents will be defined as any agent applied to the surface of the skin that alters the outcome of the facial burn. Therefore, the classic concept of topical therapy will be expanded and developed within two major stages: acute and rehabilitation. Comparison of the effectiveness of the different treatments and relevant literature will be discussed.

Severe multiple extensive postburn contractures: a simultaneous approach with total scar tissue excision and resurfacing with dermal regeneration template.

Deep partial or full-thickness burns if untreated, neglected, or managed conservatively can develop dysfunctional scar contractures with severe deformities and significant reduction in patient's activities of daily life. These burn sequelae can require multistage procedures to restore anatomy and function. These include single scar release, use of skin grafts, skin expansion, regional or free musculocutaneous or fasciocutaneous flaps to achieve adequate functional improvement. The use of dermal regeneration template (Integra), initially used in primary burns reconstruction, has been already described and compared in single scar contracture-releasing procedures, but to our knowledge, it has not been used in the simultaneous releasing of multiple severe extensive postburn contractures. A simultaneous approach with total scar tissue excision and resurfacing with Integra may reduce the number of operations and the prolonged time period of treatment required by conventional procedures of multistage scar contracture release. A 7-year-old girl, who developed severe postburn scar contractures involving the right upper limb, right axilla, neck, and face after healing of a deep 16% total body surface area burn injury, was treated with this approach. Restoration of anatomy and function, with significant improvement in the range of movement of the involved regions, was achieved in a relatively short period of time (15 weeks) with limited donor-site morbidity and preservation of donor areas for possible future procedures. Total scar tissue excision and resurfacing with Integra should be considered as a valid option in case of simultaneous management of severe multiple extensive scar contractures.

Pneumococcal septicaemia with Purpura fulminans in an 11-month-old child.

Purpura fulminans (PF) is a syndrome characterised by acute onset of rapidly progressive haemorrhagic necrosis of the skin due to dermal vascular thrombosis, mainly occurring during meningococcal sepsis. It occurs rarely in the course of infection with Streptococcus pneumoniae and most cases report Meningococcus as the causing agent. This is a case report of successful conservative limb-preserving management of PF and sepsis caused by Streptococcus pneumoniae in an 11-month-old girl.

Variations in clinical audit collection: a survey of plastic surgery units across the British Isles.

INTRODUCTION: Clinical audit is a requirement of good medical and surgical practice and is central to the UK Government's plans to modernise the NHS. MATERIALS AND METHODS: A survey was conducted to assess clinical audit data collection and collation within plastic surgery departments across the UK. The survey identified a variety of different data collection and collation methods, with extensive differences between plastic surgery departments. Those responsible for data collection and its funding were also identified by the survey. RESULTS: Results were obtained from 45 plastic surgery departments. Of the 45 departments surveyed, 12 collect data prospectively, whereas 26 units collect data retrospectively. The remaining departments collect data using a combination of methods. Of the units surveyed, 28 collect data on paper-based systems, with only 13 units using electronic applications. The personnel responsible for data collection were identified as being junior doctors. Departments collecting data prospectively do so from a greater number of sources than those collecting data retrospectively. CONCLUSIONS: This survey has focused on plastic surgery. The authors believe that similar results would be obtained from a survey of other surgical specialties. A huge variation in all parameters relating to the collection and collation of clinical audit data is seen. There are few standards within this specialty for data collection. Much work must be done in order to reach targets set by the UK Government.
