New Method of Predicting Dry Weight Using the Relationship between Ultrafiltration amount and Percentage Changes in Extracellular Fluid to Total Body Water Ratio in Maingenance Hemodyialysis Patients

초록

Differences in the slopes of the ultrafiltration amount removed during hymodialysis session vereus percent change in extracellular fluid/total body water ratio plot for right lower extremities in the normohydrated and overhydrated states mjght enable dry weigh to be predicted. Based on 8-polar BIA measurements, we developed a new method of predicting DW using the relationship between UF amount and percentage vhange in ECF/TNW ratio at right lower estrenities after HD. The devised method appears to be as accurate as the normovolemia/hypervolemia method.
