RESUMO
Objectives:The purpose of this study was to measure the body composition of malnourished patients by bioelectrical impedance analysis. Methods:Body composition was measured by bioelectrical impedance analysis in 68 malnourished patients and 78 healthy subjects. Results:The investigation showed that malnutrition patients were characterized by a depletion in fat mass,fat free mass, body cell mass,intracellular mass and an expansion of extracellular mass( P
RESUMO
Objectives:The purpose of this study was to measure the body composition of malnourished patients by dual energy X ray absorptiometry. Methods:Body composition was measured by dual energy X ray absorptiometry in 56 manlnourished patients and 72 healthy subjects. Results:Compared with control,patients had lost?(on average)?17.8?kg of body weight (P0.05). Conclusions: Reduced body weight in malnourished patients was due to loss of fat tissue and lean body mass.
RESUMO
Lipid emulsion, glucose, amino acids, electrolytes, vitamins and trace ele- ments were mixed in a definite order to prepare 10 different total nutrient admixture solutions. The pH and osmolality of these solutions did not change significantly during 14 days of storage at 4℃.Mean diameters of the lipid particles on different occasions for the different solutions varied from 0.3135?0.1012?m to 0.4813?0.1893 ?m. 94.93% of particles were less than 0.6 ?m, and none greater than 6?m. Cultures were all negative.74 patients received 1,796 such infusions. No adverse clinical reactions or abnormal laboratory parameters were observed. Patients on treatment for more than one week showed improved nitrogen balances. Serum transferrin and albumin were increased to varying levels when treatment was for more than two weeks.
