An Analysis Of Protein-energy Malnutrition In Patients With Severe Burns

Objective To investigate and analyze the nutritional status of protein and energy in patients with severe burns during 2 weeks post-burn.Methods1.To investigate the intake of protein and energy in patients with severe burns at different times post-burn. 2.To calculate the ratio of average target requirements and actual intake of protein and energy one person per day post-burn. 3.To analyze the nitrogen balance in 24 hours and the concentration of serum biochemical indices at different times post-burn. 4.Statistical Methods Statistics and data were processed using the SPSS19.0 software. Measurement data were showed by(?x±s), using two independent sample T-text. Count data were showed by rate. P<0.05 was considered statistically significant.Results 1.The average intake of protein and energy one person per day at different times post-burn From days 3 to 7 and days 8 to 14 post-burn, the intake of energy per person per day was respectively(2072±182)kcal and(2675±312)kcal, and the intake of protein was(94.3±12.4)g and(127.6±14.7)g respectively. At the same time, the ratio of calorie and nitrogen was respectively 137 kcal to 1g.and 131 kcal to 1g. 2.The average intake of protein and energy one person per day by different nutritional paths at different times post-burn The average intake of protein and energy by different nutritional paths one person per day from days 8 to 14 post-burn was higher than those from days 3 to 7. 3.The ratio of average target requirements and actual intake of protein and energy one person per day post-burn From days 3 to 7 and days 8 to 14 post-burn, the average energy intake per person per day was accounted for 65.3% and 90.6% of the target requirements, and the average protein intake was accounted for 59.5% and 86.2% of the target requirements. 4.The concentration of urinary nitrogen discharges in 24 hours, blood glucose, triglycerides, albumin and prealbumin 53 patients were in a state of negative nitrogen balance since the mean of urinary nitrogen discharges in 24 hours was 2 to 3 times than the upper limit of normal value from days 5 to 7 and days 10 to 12 post-burn. The blood glucose level meet the recommendation that the concentration of blood glucose in critical patients should be controlled ?10mmol/L. Simultaneously, the concentration of triglycerides, serum albumin and prealbumin were lower than the normal value.Conclusion 1.53 patients with severe burns were suffering from protein-energy malnutrition during 2 weeks post-burn. 2.The average intake of protein and energy by different nutritional paths one person per day from days 8 to 14 post-burn was higher than those from days 3 to 7. 3.The daily intake of carbohydrate and fat didn't lead to the metabolic overload, which means that it is necessary to increase the nutrient daily intake adequately.
