The application of bioelectrical impedance measurement of body composition in patients with liver diseases / 肠外与肠内营养

The status of bioelectrical impedance measurement especially the multifrequency segmental bioelectrical impedance measurement of liver diseases is introduced.The multifrequency segmental bioelectrical impedance can well rule out the impact from the change of body weight caused by edema and ascites,and can evaluate the volume of ascites.Compared with single frequency bioelectrical impedance,the multi frequency bioelectrical impedance measurements probably display good prospect.It helps to produce objective judgement on nutrition status and energy metabolism for patients with liver diseases.The effect,however,needs further clinical research.
