不同出生体重对新生儿静息能量消耗影响研究

The effect of different birth weight on neonatal resting energy expenditure

为观察不同出生体重对新生儿静息能量消耗的影响,采用间接能量测定仪(Deltatrac^(TM)Ⅱ,芬兰产)成功检测180例健康新生儿,其中男孩95例,女孩85例,按出生体重分成3组,即<30008组,3000g～3999g组,和≥4000g组。结果显示:体重<3000g的新生儿能量消耗与体重在3000g～3999g之间的新生儿能量消耗无差异,而体重≥4000g的新生儿能量消耗与他们差异均有显著性。提示出生体重≥4000g的新生儿静息能量消耗明显低于体重在4000g以下的新生儿。

To evaluate the effect of different birth weight on neonatal resting energy expenditure. 180 healthy neonates including ninety-five boys and eighty-five girls, were prospectively determined by indirect calorimeter. They were divided into three groups according to their birth weight, which were <3000g group, 3000g-3999g group, and ≥4000g group. The result showed that there was no significant difference in resting energy expenditure between neonates whose birth weight was below 3000g and those whose birth weight was 3000g - 3999g. But, a very significant different could be found among the neonates with more than 4000g group and those in other two groups. The conclusion suggests that the resting energy expenditure of newborns whose birth weight is equal or more than 4000g is lower than that of newborns below 4000g.
