title: [Statistical study regarding anemia in patients admitted with epistaxis. Importance of its control and the associated risk factors].
abstract: OBJECTIVE
  To emphasize the importance of hemodinamic control and risk factors in the patients hospitalized due to epistaxis.
  
  
  METHODS
  Retrospective study of 200 consecutive patients admitted by such cause between 1997 and 2004 of whom 46 (23%) developed some degree of anemia. Among other clinical variables we analyze the present risk factors, age, sex, levels of hematocrit and hemoglobin, origin of the nasal hemorrhage, number of transfusions that were required and type of nasal packing used.
  
  
  RESULTS
  We prove a significant statistical association (p<0,01)) between epistaxis with anemia and risk factors. About 39% of the anemizing epistaxis needed a transfusion, generally red cell concentrates.
  
  
  CONCLUSIONS
  Every admitted epistaxis needs a good hemodinamic study and control of the patient and the treatment of the base pathology associated.
