Abstract

Knowledge of hydration status is essential in the clinical evaluation of patients with chronic kidney disease, both before and after starting replacement treatments. The objective of this review is to analyze the methods of assessing dry weight in hemodialysis patients through the use of different techniques, carrying out a correct physiological assessment and identifying a good nutritional status of the patients. A bibliographic review was carried out, using documentary analysis, of articles compiled from a bibliographic search in prestigious international databases. As results, it was found that among the methods for assessing dry weight are chest x-ray, ultrasound of the vena cava, cardiac biomarkers, assessment of plasma volume and electrical bioimpedance. It was determined that among the most important dry weight assessment methods are vena cava ultrasound, being a non-invasive method, and electrical bioimpedance.
