Background: Iron deficiency anemia is a major complication of chronic renal failure, with as most common cause, erythropoietin deficiency. Objective: Analyze the relative deficiency anemia iron and erythropoietin in patients with chronic renal failure undergoing hemodialysis. Methods: This is a descriptive study, cross, document, with a quantitative approach carried out in a clinic specializing in kidney treatment in which the sample consisted of 72 patients with chronic kidney disease. The study was conducted during the period January to December 2013. A semistructured questionnaire itself was used. The processing of data was by descriptive epidemiology. The project was approved by the Research Ethics Committee, protocol number 705677. Was analyzed by analysis of the records, the monthly record of laboratory hemoglobin, hematocrit, transferrin saturation and ferritin index, within one year. Descriptive statistics were presented in percentages. The average annual variation of laboratory levels of each patient were classified according to the reference values used: low, high or target. Results: The average age of the 72 patients was 44 +/- 14, 79% male and 21% female. Hemoglobin less than 11g / dl was found in 25% of patients. Iron deficiency (SAT%<20%) was diagnosed in 7%. It was observed that 8% had ferritin levels lower than expected (<200ng/dL). Of all patients with (SATA%<20%), 4.2% had ferritin within normal parameters, one patient had increased ferritin levels, and another patient showed up with decreased ferritin values. Of patients considered anemic, 18.05% had% Normal SAT and high ferritin. Conclusions: The hemoglobin variability occurs most commonly at higher levels than at lower values. It is necessary to carry out further studies in order to obtain larger emplacements for the correction of anemia in patients with CKD.
