烧伤患者能量消耗变化相关因素的分析

目的　动态监测烧伤后能量消耗 (简称能耗 ) ,探讨影响伤后能量消耗的因素。　方法　应用间接测热仪对 45例烧伤患者进行能耗的动态监测并分析其能耗变化。　结果　烧伤后能耗即刻升高 ,一周左右达高峰 ( 1144 3.78± 32 95 .32 )kJ/d ;烧伤面积越大 ,能耗越高 ;能耗与烧伤后病程有关 ;伤后能耗有变异且接近早期 ,烧伤面积越大变异程度越高 ;中等面积烧伤合并吸入性损伤患者能耗较无吸入性损伤患者高 ;大面积烧伤切痂术后能耗明显下降 ;男性患者能耗高于女性患者。　结论　烧伤后能耗有一定规律性变化 ,但深度烧伤面积、伤后时间、吸入性损伤、切痂手术、性别及个体差异均影响烧伤后能耗

Analysis of the factors related to the change of energy expenditure in burned patients

OBJECTIVE: To analyze the factors related to the change of energy expenditure in burned patients. METHODS: Indirect calorimetry was employed to detect energy expenditure (EE) dynamically in 45 cases of burned patients and to analyze their change. RESULTS: EE increased immediately postburn and reached top level in about one week (11, 443.78 plus minus 3, 295.32) kJ/d. EE value was positively correlated to the size of burn area. EE was also correlated to the development of the disease. The EE variation happened in the early postburn stage. The degree of variation was positively correlated to the size of burn area. The EE value in patients with medium size burn and inhalation injury was higher than that without inhalation injury. Postoperative EE decreased obviously in patients with major burn who had undergone escharectomy. EE in male patients was higher than that in female. CONCLUSION: Postburn EE varied with some regularity, but was affected by burn depth and size, postburn time, inhalation injury, escharectomy, sex and individual difference.
