Thrombosis incidence in major paediatric burns.

BACKGROUND: Major burns are associated with multiple risk factors for thrombosis such as decreased mobilization and systemic inflammation. It is unclear if these factors are offset by the inherent lower thrombosis risk in the paediatric patient. As such there is no consensus on thromboprophylaxis for paediatric burns patients, in contrast to this being a mainstay of treatment in the adult population. This retrospective cohort study examines the incidence of, and risk factors for, thrombotic events in major paediatric burns with a view to establish guidelines for prevention. METHOD: Review of major paediatric burns, defined as % total body surface area (%TBSA) ≥30%, at the Adelaide Women's and Children's Hospital (WCH) over a 16-year period. Coding data and the local burns database were used to identify participants with subsequent review of case files. RESULTS: Of the cohort (n = 23), six cases (26%) were complicated by thrombotic events. These patients had the most extensive burns averaging 68.5% TBSA, longer PICU admissions and associated interventions. These data points were more than doubled in the cohort diagnosed with a thrombus. Of the six events, five were secondary to central venous catheters (CVC) and one deep venous thrombosis (DVT) to the left calf. CONCLUSION: The incidence of thrombotic events in our study was significant albeit in a small population. There is a strong association between large %TBSA and thrombus, with clots mostly forming around CVCs. While further research is required, this study demonstrates screening and targeted thromboprophylaxis may be required for major paediatric burns.

A comparison study of methods for estimation of a burn surface area: Lund and Browder, e-burn and Mersey Burns.

INTRODUCTION: One of the greatest challenges in burn care is the estimation of a total burn surface area (TBSA). It is especially challenging and needs to take into account the growing proportions and the age of a paediatric patient. The aims of this study is to: (1) assess the reliability of the three modalities (LB, MB, and EB) in calculating the extent of burn injuries and fluid resuscitation, and (2) compare the features in terms of usability and efficacy. METHODS: Participants were recruited from Women's and Children's Hospital (WCH), South Australia's surgical and emergency department. Participants were introduced to LB, MB and EB, and then commenced calculation of TBSA on two simulated paediatric (patient A: 12 months, patient B: 4 years) burns. The participants were categorized into three groups; (1) Burns-naïve, (2) Burns-experienced, and (3) Burns-expert. RESULTS: A total of 45 participants took part in this validation study: doctors (49%), nurses (33%), nursing students (11%) and medical students (7%). The burns-naïve group demonstrated higher means in both patients and has greater variance, TBSA mean 28.8%, range 14-40.5% and mean 37.4%, range 20-52.3% in patient A and B respectively. Two-way ANOVA analysis shows a statistically significant interaction between the effects of level of experience and use of applications on estimation of TBSA in larger burns. CONCLUSION: Innovative software and mobile applications demonstrate a high potential as clinical adjuncts in achieving better health outcomes in any health care system. Both Mersey Burns and e-burn reduced the risk of human error particularly from untrained or non-specialised clinicians, however, e-burn proved to be more favourable in our study. Technology-aided models are the future of burns assessment, and further studies are warranted to determine their impact on overall clinical outcome.

Mortality in paediatric burns at the Women's and Children's Hospital (WCH), Adelaide, South Australia: 1960-2017.

BACKGROUND: Burn injuries are the third leading cause of preventable death in children worldwide, resulting in over 100 000 annual hospitalisations. In the paediatric population, scalds are the commonest mechanism and burn injuries of greater than 40% total burn surface area (TBSA) are associated with a high mortality and morbidity rate. AIMS: The aim of this study was to review mortality in paediatric burns in a tertiary burns centre over a 60-year period, providing an understanding of local causes of mortality and directing future clinical research. METHODS: We reviewed data collected prospectively from patients treated for burn injuries at the WCH from 1960 to 2017. Data of age, gender, mechanism of injury and TBSA were collected. TBSA of 40% and greater were included in the study. RESULTS: All patients with total burn surface area (TBSA) less than 40% survived. There were a total of 75 patients who sustained burns of or greater than 40% TBSA. Overall mortality was 34% (26 of 75) of which 24 occurred in the 1960s. Of the 21 patients who died of flame burn injuries, 12 of them were described as clothes catching alight from being in close proximity to the source of flame. Average length of stay for patients who did not survive was 7 days (1-26). CONCLUSION: Mortality has since declined and the prognosis for survival good, even in TBSA of greater than 90%. The investigations in fabric flammability led by Dr Thomas Pressley and Mr Murray Clarke prompted the rewriting of Australian standards for production of children's clothing. This, in combination with advances in paediatric resuscitation, surgical techniques as well as wound care has improved survival rates and outcomes in extensive burn injuries. Future studies focus to see not only better survival rates, but also better aesthetic and functional outcomes in burn survivors.

Adrenaline-induced digital ischaemia reversed with phentolamine.

Adrenaline autoinjectors are widely prescribed for self-treatment of anaphylactic syndromes. Accidental misfire into digits can cause prolonged significant ischaemia with serious outcomes. Phentolamine is a readily available treatment, which is easily and safely given in the emergency setting.

Familial Parry-Romberg disease.

Parry-Romberg disease (or hemifacial atrophy) is a rare condition affecting the face. It commences in childhood but its aetiology remains unknown, and is sporadic. Two cases are presented who were biological first cousins. We believe that this is the first recorded example of this condition occurring in family members.
