[Assessment of nutritional metabolism in severe burned patients by bioelectrical impedance analysis].
OBJECTIVE
To detect body composition and evaluate the influence of body composition on nutritional assessment of burned patients by BIA(bioelectrical impedance analysis).


METHODS
Body composition was determined in 38 burned patients (32male, 6female) with total burn area 10% approximately 80%(mean 33.1%+17.61%) by BIA during day 1 to day 70 after burns. All patients were divided into two groups: 20 cases in group A (total burn areas >30%), 18 cases in group B (TBSA <30%). Adequate number calories provided by indirect calorimetry.a


RESULTS
two patients died of MODS in the two groups, 36 patients were survived, mean days of stay hospital 33.1+17.6, the value of lean body mass and body fat mass are gradually decreased, lean body mass is especially lower in the two groups despite provided adequate number calories, there is a significant difference in static analysis in the two groups(P<0.05).a


CONCLUSIONS
The serve catabolism is prevalent in treatment procedure of the burned patients with major burn, the lower of lean body mass is not changing despite provide adequate caloris in the two groups. It is a simple and precisely method that bioelectrical impedance analysis could measure body composition; it may help objectively assess nutritional status of severe burned patients.
