生物电阻抗技术在维持性血液透析患者营养状况评估中的研究进展

Advances in Research on Nutritional Status Assessment of Bioelectric Impedance Technology in Maintaining Blood Dialysis Patients

摘要: 维持性血液透析患者并发症中营养不良发生率较高，且常常预示高住院率及高死亡率。及时评估血透患者的营养状况并给予干预，对提高患者的生活质量及改善长期预后有着重要意义。生物电阻抗技术在维持性血液透析患者营养状况评估中具有可操作性、重复性强、且为无创检查、可对人体体内成分的各种指标实现定量分析等诸多优点，患者容易接受，且能够长期监测血液透析患者的营养状况，及早发现营养不良，有助于早期开展高危患者的营养干预及干预效果的动态评价，现已在临床上应用。本文旨在对维持性血液透析患者的营养现状及生物电阻抗技术在评估维持性血液透析患者营养状况中的应用进行综述。

Abstract: The incidence of malnutrition is high in complications in patients with maintenance hemodialysis, and often indicates high hospitalization rate and high mortality. Timely evaluate the nutritional status of blood absorbing patients, which has important significance for improving the quality of life and improving long-term prognosis. Biological impedance technology has its operability, repetitiveness, strong recipient, and non-invasive inspections, and has a variety of indexes of the individual components of the human body, and patients are easily accepted. It is possible to monitor the nutritional status of blood dialysis patients, and early detection of malnutrition, which helps to develop a dynamic evaluation of nutritional intervention and intervention effects in early high-risk patients. It is now used in clinical practice. This paper aims to review the nutritional status and bioelectric impedance techniques for the maintenance hemodialysis patients to evaluate the application of the nutritional conditions in maintaining hemodialysis patients.
