Some Burning Questions

Burn injuries represent a major cause of mortality and morbidity as well as a significant drain on limited resources, particularly in the developing world. Advances in resuscitation, critical care, protective ventilatory strategies, earlier complete debridement complemented by more aggressive treatment of burn wound sepsis have reduced the mortality of thermal injuries. There has also been a move to focus on education and prevention campaigns, which have borne fruit and resulted in some reduction in the incidence of burns in the paediatric population. Burn care, once a Cinderella specialty, has become a well focused multi-disciplinary specialty in its own right. Burn injury is dissimilar to many forms of trauma. In major burns, the initial trauma may be limited to the skin alone or skin and lungs, but all organ systems are rapidly involved as the physiological derangement becomes systemic. The burden of this multi-system insult is substantial. Globally, the World Health Organisation estimated that fire-associated burns alone directly resulted in over 320,000 deaths in 2002, and in the USA, approximately 1million children sustain burns each year. Australasian guidelines suggest that all adult burns with greater than 15% total body surface area (TBSA) and >10% TBSA burn in children will require fluid resuscitation and possibly critical care support at some point in their hospitalisation. Mortality in these patients with severe burns follows a bimodal pattern of early and late deaths. Causes of early death comprise refractory shock, inability to obtain a safe airway or provide adequate oxygenation, co-existent trauma, non-survivable carboxyhaemoglobin poisoning, and decisions that injuries are non-compatible with recovery, leading to therapy withdrawal. With improved resuscitation strategies, 95% of patients survive the early resuscitation phase. Late deaths are secondary to sepsis normally associated with wound infection and multiple organ failure. The morbidity associated with burn injury continues well after the acute hospital admission, frequently for up to several years post burn injury, as is witnessed by prolonged rise in basal metabolic rate and worsening scar tissue1, 2. It has been calculated that in children approximately 60% of the cost of burn care occurs post wound closure; that is, dealing with the disabling and disfiguring contractures associated with hypertrophic scar3, 4. Hence, research and new modalities are being aimed at reducing cost of treatment and improving quality of life for survivors of burn injury. Thus, this PhD aims to reflect the multidisciplinary nature of modern day burn care, with the inclusion of seven published papers and one book chapter covering prevention and education relevant to paediatric burns, treatment and minimisation of wound infection , and scar minimisation, along with the first study into the relevance of fetal wound healing post burn injury.
