We assessed the utility of bioelectric impedance plethysmography (BIA) for measuring acute volume changes and body composition in patients with renal disease. Chronic hemodialysis and peritoneal dialysis patients were evaluated before and after dialysis. Total body water, as measured by BIA, predicts body weight. Acute changes in body water, induced by dialysis, are not predicted well by data derived from BIA. Body fat (%) and fat-free mass (%), determined by anthropometry, are predicted well by body composition data derived by BIA. BIA is useful for assessing body composition in this population, but must be cautiously applied to the measurement of acute volume changes.
我们评估了生物电阻抗体积描记法（BIA）在测量肾病患者急性容量变化和身体成分方面的效用。对慢性血液透析和腹膜透析患者在透析前后进行了评估。通过BIA测量的总体水可预测体重。透析引起的身体水分急性变化，通过BIA获得的数据无法很好地预测。通过人体测量法测定的体脂（%）和去脂体重（%），可通过BIA得出的身体成分数据很好地预测。BIA有助于评估该人群的身体成分，但在测量急性容量变化时必须谨慎应用。
