【摘要】“干体质量”是评价血液透析患者透析充分性最简便、最重要的指标，对于提高患者生存率和生存质量至关重要。临床上评估透析患者“干体质量”的方法多种多样。其中，人体成分监测仪（body composition monitor，BCM）因其检测结果更加直观，不受主观因素影响，同时具有无创、廉价、时效性强、操作简便、可以床边使用等多方面优势，在临床中的应用日益广泛。

【Abstract】"Dry weight" is the simplest and most important indicator to evaluate the adequacy of dialysis in hemodialysis patients, and is crucial for patient survival and the quality of life. There are many approaches to clinically evaluate "dry weight" for dialysis patients. Body composition monitor is the“dry weight”measurement method widely used in clinical practice due to its non-invasive, low expense, intuitive and objective results obtained in a short period of time, and easy to operate along bedside.
