s Background Acute kidney injury (AKI) is a critical complications in severely burned patients associated with high morbidity and mortality. The purpose of this study was to investigate the impact of severity of AKI at the time of continuous renal replacement therapy (CRRT) start on patient outcome and to identify the prognostic factors in severely burned patients with CRRT application. Methods From January 2007 to June 2010, 84 burn patients with more than 40% of total body surface area (TBSA) burned who treated with continuous renal replacement therapy for acute kidney injury were analyzed retrospectively. Results There was no significant difference of mortality by the severity of AKI at the time of CRRT start. However, the mean TBSA burned, abbreviated burn severity index, arterial pH, partial pressure of carbon dioxide (PaCO 2 ) and blood urea nitrogen (BUN)/creatinine (Cr) ratio had a statistical significance to predict mortality in receiver operation characteristic curve. In a multivariate logistic regression analysis, only sepsis had an independent association with mortality. Conclusions The severity of the AKI at the time of CRRT start did not have significant relationship with patient outcome. CRRT can be applied to minimize the complication of AKI including electrolyte imbalance and volume overload. Because only the presence of sepsis was independently associated with mortality, treatment for sepsis should be focused to improve the survival of the severely burned patients with CRRT.

PURPOSE: To determine epidemiological trends among burns patients admitted to our burns center during 2003-2012, and the usefulness of the Abbreviated Burns Severity Index (ABSI) for predicting burns-related mortality. METHODS: We retrospectively reviewed the data of 4481 burns patients. We analyzed the epidemiological trends and ABSI scores using Student t-test and one-way analysis of variance (continuous variables), chi-square test (categorical variables) and stepwise logistic-regression analysis (predictors of mortality). RESULTS: The mean age and male-to-female ratio were 39.9±19.7 years and 2.88, respectively. ABSI scores decreased from 7.7±3.0 in 2003 to 6.9±3.0 in 2012. Mortality rate improved from 24.5% in 2003 to 15.8% in 2012. Burns were caused by flames (67.3%), scalding (22.0%) and electrical (7.5%), chemical (1.6%) and contact (1.5%) injuries. Scalding and flames were the most common causes in patients aged ≤20 years and ≥21 years, respectively. Female sex, inhalation injury, full-thickness burns, large total body surface area (TBSA) burned and old age predicted mortality. ABSI scores 14 were associated with 0.7% and >90% mortality, respectively. CONCLUSIONS: The mortality of major burns has decreased but remains high. ABSI scores predict burns-related mortality.

This study was to re-evaluate inhalation injury as a prognostic factor in burn patients and to determine the factors that should be considered when refining the definition of inhalation injury. A total of 192 burn patients (152 men, 40 women; mean age, 46.1±13.8 years) who were suspected to have an inhalation injury and underwent bronchoscopy between January 2010 and June 2012 were included in this prospective observational study. All patients underwent bronchoscopy within 24h of sustaining the burn. The bronchoscopic findings were classified as normal, mild, moderate, and severe. Mechanical ventilation was administered, when required. Age, percentage of TBSA burned, ABSI score, requirement of mechanical ventilation and PF ratio, but not inhalation injury, COHb level, and bronchoscopic grades, significantly differed between the survivors and non-survivors (p

We address the clinical application of the suspension type cultured epithelial autografts (CEAs), Keraheal™ (MCTT, Seoul, Korea), along with the effects, application method, merits and demerits thereof. From February 2007 to June 2010, 29 burn patients with extensive burns, participated in the suspension type of CEA clinical test. A widely meshed autograft (1:4-6 ratio) was applied to the wound bed and the suspension type CEA was sprayed with a Tissomat cell sprayer, followed by a Tissucol spray, a fibrin sealant. The patients' (men/women=26/3) median (interquartile ranges) age was 42 (30-49) years old, the burned TBSA was 55 (44-60) %, and the full thickness burn area was 40 (30-46.5) %. The area of Keraheal™ applied was 800 (400-1200) cm(2). The take rate was 96 (90.5-99) % and 100 (98.5-100) % at 2 and 4 weeks after treatment with Keraheal™, respectively. The Vancouver burn scar scale was 5 (4-6.5), 4 (3-6), and 3 (2-4) at 8, 12 and 24 weeks after the Keraheal™ application. Widely meshed autograft must be applied in massive burns but it's take rate is greatly reduced. The CEAs enhance the take rate of a wide meshed autograft in massive burns and allow for grafting wide meshed autograft together with acellular dermal matrix in some cases.

In efforts to prevent and reduce joint contracture and scar formation after burn, we used the acellular human dermis (AlloDerm) as a dermal replacement in the acute stage. A total of 64 patients received AlloDerm graft selectively on joint areas during the study period from March, 2005 to July, 2007. From January to March, 2008, a total of 31 patients returned to our burn center to examine the functional results by measuring range of motion of joints. Additionally, the quality of grafted skin condition criteria of skin elasticity, scar thickness, trans-epidermal water loss, melanin and erythema level was measured in a total of 11 patients among them. By analyzing the limitation level of 55 joints excluding hand areas, we found that 24 joints (43.6%) showed no limitations, 12 joints (21.8%) showed limitations below 10%, 16 joints (29.1%) showed limitations between 10 and 19% and 3 joints (5.5%) showed limitations over 20%. The scar thickness of non-AlloDerm applied areas was 2.5+/-0.9 mm and AlloDerm applied areas was 1.8+/-0.7 mm (p = 0.396). Trans-epidermal water loss for non-AlloDerm applied areas was 20.9+/-7.7 g/h/m(2) and AlloDerm applied areas was 10.8+/-3.4 g/h/m(2) (p
