Abstract
INTRODUCTION Abnormal fibrinolysis early after injury has been associated with increased mortality in trauma patients, but no studies have addressed patients with burn injury. This prospective cohort study aimed to characterize fibrinolytic phenotypes in burn patients and to see if they were associated with mortality. METHODS Patients presenting to a regional burn centre within 4 h of thermal injury were included. Blood was collected for sequential viscoelastic measurements using thromboelastography (RapidTEG™) over 12 h. The percentage decrease in clot strength 30 min after the time of maximal clot strength (LY30) was used to categorize patients into hypofibrinolytic/fibrinolytic shutdown (SD), physiological (PHYS) and hyperfibrinolytic (HF) phenotypes. Injury characteristics, demographics and outcomes were compared. RESULTS Of 115 included patients, just over two thirds were male. Overall median age was 40 (i.q.r. 28-57) years and median total body surface area (TBSA) burn was 13 (i.q.r. 6-30) per cent. Some 42 (36.5 per cent) patients had severe burns affecting over 20 per cent TBSA. Overall mortality was 18.3 per cent. At admission 60.0 per cent were PHYS, 30.4 per cent were SD and 9.6 per cent HF. HF was associated with increased risk of mortality on admission (odds ratio 12.61 (95 per cent c.i. 1.12 to 142.57); P = 0.041) but not later during the admission when its incidence also decreased. Admission SD was not associated with mortality, but incidence increased and by 4 h and beyond, SD was associated with increased mortality, compared with PHYS (odds ratio 8.27 (95 per cent c.i. 1.16 to 58.95); P = 0.034). DISCUSSION Early abnormal fibrinolytic function is associated with mortality in burn patients.

Abstract
UNLABELLED Alloderm has been advocated for the management of acute burns. However, few studies have demonstrated the feasibility of this technique. METHODS We reviewed the medical records of all patients treated in our burn center who received Alloderm since 1999. RESULTS Alloderm was used in 21 burn patients and 6 patients with traumatic skin loss. The average size of Alloderm used in the burn patients was 517+/-144 cm(2) (range 24-3000 cm(2)). The average Alloderm thickness used was 0.008 in. and autografts were harvested at an average of 0.007 in. Overall, Alloderm was used in a variety of locations including the face in 3 patients (2 burns, 1 traumatic skin loss) and hands in 7 patients (6 burns, 1 traumatic skin loss). Successful take was observed in 26/27 patients. CONCLUSIONS Alloderm can be used successfully in patients with acute burns requiring grafting.
