摘要
目的观察老年胃肠道肿瘤病人静息能量代谢(Resting Energy Expenditure,REE)的特点。方法选择老年(≥60岁)胃肠道肿瘤患者和非肿瘤患者(对照组)各60例,应用间接测热仪对其进行REE测定,根据MNA法评价营养状况,计算Harris-Benedict公式预测值。结果老年男性肿瘤患者REE较对照组低,且差异有统计学意义;H-B公式预测值明显高于REE测定值,差异有统计学意义;临床估计能量供给的经验值平均为REE测量值的1.5倍。结论老年胃肠道肿瘤患者静息能量消耗较非肿瘤患者有所下降,H-B公式法不能准确预测病人的能量消耗,经验估计值可能会造成过度喂养。
Objective To observe the features of resting energy expenditure（REE） in elderly patients with gastrointestinal cancer.Methods Sixty patients with gastrointestinal cancer and 60 non-cancer patients at the age of 60 or over 60 years were enrolled as experimental group and control group,respectively.Their REE was assessed by indirect calorimetry and their nutritional status was estimated by mini-nutritional assessment（MNA）.The REE value was predicted following the Harris-Benedict equation.Results The REE was lower in experimental group than in control group（P0.05）.The REE value predicted following the Harris-Benedict equation was significantly higher than the detected REE value（P0.05）.The average empirical value of estimated energy expenditure was 1.5 times that of the measured REE.Conclusion The REE is lower in elderly male patients with gastrointestinal cancer than in those with no gastrointestinal cancer.The Harris-Benedict equation cannot accurately predict energy expenditure and empirical value may lead to over-feeding in such patients.
