新生儿肺炎能量代谢测定研究

Study on the measurement of energy metabolism in newborns with pneumonia

为探讨新生儿肺炎能量代谢的规律 ,应用开放式间接能量测定仪对15例新生儿肺炎患儿进行睡眠代谢率 (SMR)测定 ,并对19例新生儿肺炎患儿进行静息能量消耗 (REE)测定。结果显示 :新生儿肺炎SMR为166.1±24.1kJ/(kg·d) ,与测定时的体重、体表面积、预测值均呈显著相关关系 ;其REE为171.7±30.3kJ/(kg·d),与肺炎病理状况有关。研究表明 :新生儿肺炎能量代谢有其特殊性 。

To explore the mechanisms of energy metabolism in newborns with pneumonia,sleeping metabolism rate(SMR)and resting energy expenditure(REE) were measured on 15 and 19 newborns with pneumonia respectively by using open indirect calorimeter.The results showed that the SMR was 166.1±24.1kJ/(Kg·d),which was correlated significantly with the weight,body surface area and predicted SMR.REE was 171.7±30.3kJ/(Kg·d),which was correlated with pathological changes of the infants pneumonia.It is concluded that SMR and REE in newborns with pneumonia possessed their own characteristics and individualized measurement of energy expenditure is necessary for the basis of their adequate nutritional support.
