Thromboprophylaxis in adult and paediatric burn patients: A survey of practice in the United Kingdom.

INTRODUCTION: Patients with burn injuries are at an increased risk of venous thromboembolism (VTE). This predisposition is secondary to the endothelial injury, hyper-coagulable state and stasis (Virchow's triad) associated with burn injury. Although the true incidence of VTE in burn patients has not been adequately quantified, symptomatic VTE occurs in 0.2-7% of this population. VTE prophylaxis has proven clinical effectiveness and affords a reduction in the morbidity associated with such events, but the benefits and risk of complications need to be balanced in order to provide the best quality of care. Owing to the lack of prospective data on VTE in burns, practice varies greatly, not only internationally, but also between local burns services. Our aim was to better understand current VTE practice within United Kingdom (UK) burn care services by performing a comprehensive survey. METHODS: We contacted all the inpatient burn care services in the UK and collected data on current VTE practice via a standardised questionnaire. Services were given the choice to complete the survey by telephone or email and a follow-up plan was formulated. RESULTS: Twenty-five burn care services were contacted and 23 agreed to participate (92% response rate). Responding services treated adults, children or both and lead burn nurses or senior medical staff familiar with current VTE practice were interviewed. Routine VTE prophylaxis was provided in 84% of burn services and the majority utilised a combination of chemoprophylaxis and thromboembolic deterrent stockings (TEDS). All used low molecular weight heparin (LMWH) as their choice of chemoprophylaxis. Of those treating adults, all used a VTE prophylaxis protocol, but none of these applied to children. Only 56% of services treating children had such a protocol. The majority discontinued prophylaxis once patients were mobile. DISCUSSION AND CONCLUSION: Although the true burden of VTE in burn patients is unknown, we recognise that they are a population at risk. In addition to changes in the inflammatory and clotting pathways associated with thermal injury, prolonged hospital stay, ventilatory support, multiple surgeries, numerous central venous cannulations and reduced mobility all multiply this risk. The risk associated with the administration of heparin (bleeding complications and heparin-induced thrombocytopaenia) is low and can be reduced even further to 0.1% by the use of LMWH. The risk of symptomatic VTE is far greater, therefore the benefits of VTE prophylaxis would seem to outweigh the risks of not undertaking prophylactic measures. A higher LMWH dose and routine monitoring of anti-factor Xa levels are useful for acute burn patients. Two previous surveys, performed in Canada and the United States of America (USA), found routine administration of VTE prophylaxis to be 50% and 76% respectively. Of the 71 centres in the USA participating in the survey, 30% used a combination of sequential compression devices (SCD) and heparin and 24% did not provide VTE prophylaxis at all. A lack of prospective data on VTE in burn patients appears to be associated with diverse practice, and consensus on this topic could ensure that the potential morbidity caused by VTE is reduced. A clinical tool for identifying patients at risk and guidelines for management will standardise practice, which in turn should allow us to improve and maintain high quality care for burn patients.

Rapidly enlarging skin lesion on the lip.

Squamous cell carcinoma (SCC) is a malignant tumour arising from the keratinising cells of the epidermis. It is slow growing, locally invasive and has the potential to metastasise to other organs of the body. We report an unusual presentation of a rapidly enlarging, well-differentiated SCC on the upper lip of a 75-year-old woman. Rapidly enlarging skin lesions in specialised areas pose great challenges in its management. As the lesions increase in size, they eliminate first-line reconstructive options that can compromise functional and aesthetic outcomes. Accurate histological diagnosis prior to surgery is paramount, as it bears significance to the excision margins. Early, urgent referral to a specialist unit is essential and may avoid the need for more invasive procedures and associated morbidity.

The template technique for breast mound planning when using abdominal flaps for breast reconstruction.

Delayed breast reconstruction with abdominal flaps typically involves a process of 'trial and error' when moulding the flap into a satisfactory breast mound. This moulding process is crucial to the final aesthetic result. We present a template technique to preoperatively plan the skin envelope of each reconstruction. Templates are quick and simple to construct, and are tailor-made based on several measurements from the contralateral breast. The technique is versatile and can be adjusted for use with Wise-pattern breast reduction or mastopexy. In our experience, the template technique reliably attains natural shape and good symmetry when compared with unplanned flap moulding.
