The objective of the present study was to investigate whether InBody 2.0 might be useful in measuring the dry weight of chronic hemodialysis (HD) patients. Thirty-five HD patients (22 males and 13 females; mean age 62.6 +/- 14.0 years; mean HD duration 101.0 +/- 118.06 months) were examined. Multifrequency bioelectric impedance analysis was used to estimate the ratio of extracellular water (ECW) to total body water (TBW). The body resistance was measured at frequencies ranging from 1 kHz to 1 MHz. The impedance index was determined at a low frequency (5 kHz) and correlated closely with ECW, using sodium bromide dilution as standard comparison. The levels of serum albumin, prealbumin, total cholesterol (TC), triglycerides (TG), transferrin, and human atrial natriuretic peptide (hANP) were measured by routine methods in our hospital. The ECW/TBW ratio was significantly associated with the levels of hANP (p < 0.05). However, no associations between the levels of serum albumin, TC, TG, or transferrin and the ECW/TBW were observed. It appears that the body composition analyzer, InBody 2.0, may be useful for estimating the dry weight in chronic HD patients.
本研究的目的是调查InBody 2.0是否可用于测量慢性血液透析（HD）患者的干体重。对35例HD患者（22例男性和13例女性；平均年龄62.6±14.0岁；平均HD病程101.0±118.06个月）进行了检查。采用多频生物电阻抗分析来估计细胞外液（ECW）与总体液（TBW）的比例。在1 kHz至1 MHz的频率范围内测量人体电阻。以溴化钠稀释法作为标准对照，在低频（5 kHz）下测定阻抗指数，其与ECW密切相关。采用我院常规方法测定血清白蛋白、前白蛋白、总胆固醇（TC）、甘油三酯（TG）、转铁蛋白和人心房利钠肽（hANP）水平。ECW/TBW比值与hANP水平显著相关（p<0.05）。然而，未观察到血清白蛋白、TC、TG或转铁蛋白水平与ECW/TBW之间存在关联。看来，人体成分分析仪InBody 2.0可能有助于估计慢性HD患者的干体重。
