生物电子阻抗测定用于评估腹部肿瘤病人手术前后的营养状况

Bioelectrical impedance assessment of nutritional status in abdominal tumor patients before and after operation

目的：评估生物电子阻抗测定（ＢＩＡ）对腹部肿瘤病人手术前、后营养状况分析的有效性。 方法：选择２４ 例腹部肿瘤病人，用ＢＩＡ分别测得术前和术后第５ 天的电阻和感应电阻，通过计算机ＲＪＬ系统计算出身体细胞质量（ＢＣＭ）、脂肪（ＦＡＴ）和身体总水含量（ＴＢＷ）值，并与白蛋白和体重的变化相比较。 结果：术后５天时，ＢＣＭ 的下降具有显著性差异（ｔ＝ ４．４１，Ｐ＜ ０．０１），这与白蛋白、ＦＡＴ、ＴＢＷ 和体重的下降是一致的。 结论：使用ＢＩＡ评估腹部肿瘤病人手术前、后营养状况的变化是可行的。

Objectives:To assess the utility of bioelectircal impedance analysis(BIA) in determining nutritional status in abdominal tumor patients preceding and following operation. Methods:Twenty four abdominal tumor patients were selected and the values of resistance and reactance were measured preceding and the fifth day following operation by BIA.The values of BCM,FAT,and TBW which were worked out through RJL computer system were compared with the changes of albumin and weight. Results: Prominent difference was seen in the decline of BCM following operation and the same outcome appeared in albumin,FAT,TBW,and weight. Conclusions:Determination of nutritional status changes in abdominal tumor patients preceding and following operation by BIA represents a feasible method.
