【摘要】 目的:研究重度烧伤病人能量代谢特点,并分析疾病严重程度和手术等因素对静息能量消耗(REE)的影响。方法:将机械通气治疗的20例重度烧伤病人,通过代谢车测定REE,并将伤后第1、3、7、14和28天测得的REE(m REE)与H-B公式计算所得REE(p REE)相比较。同时,比较APACHEⅡ评分≥15分与<15分组、手术前1 d与术后24 h的m REE。结果:1伤后第1、3、7、14和28天时,m REE值介于p REE 1.5与p REE 2.0之间。2APACHEⅡ≥15分组的m REE高于APACHEⅡ<15分组(P<0.05)。3术后24 h的m REE水平较术前1 d显著降低(P<0.05)。结论:重度烧伤病人应用代谢车测定的REE介于p REE 1.5与p REE 2.0之间。病情危重程度和手术可能对REE水平有影响。更多还原

【Abstract】 Objective: To study the energy metabolism in severely burned patients and analyze the effects of operation and severity of illness on REE. Methods: 20 cases of severe burns with mechanical ventilation were enrolled. On the 1st,the 3rd,the 7th,the 14 th and 28 th day,resting energy expenditure( REE) were measured by the metabolic cart and were compared with p REE. The difference of m REE was observed between the APACHE Ⅱ score ≥15 group and APACHE Ⅱ < 15 group. The difference of m REE was compared before and after operation. Results: The values of m REE were between p REE 1. 5 and p REE 2. 0 on the 1st,the 3rd,the 7th,the 14 th and 28 th day. The m REE of APACHEⅡ≥15 group were significantly higher than that of APACHEⅡ < 15 group( P < 0. 05). The level of m REE after operation was significantly lower than that before operation( P < 0. 05). Conclusion: The values of m REE aer between p REE 1. 5 ~ 2. 0 in sever burn patients. Severity of illness and operation possibly have the effect on the level of REE in these patines.更多还原
