Importância do perfil hematimétrico do doador: uma revisão narrativa da literatura

Abstract

Introduction: Anemia is contextualized by the World Health Organization (WHO) as "a state in which the blood hemoglobin concentration is abnormally low as a result of the lack of one or more essential nutrients, whatever the origin of this lack." It is estimated that 90% of anemia cases are caused by iron deficiency. One of the causes that can result in anemia is blood donation. The increasing use of blood as an important therapeutic use required consequently progressive increase in the number of blood donors Objective: In this paper we related the importance of determining the hematimetric profile of recurrent blood donors. Methods and Materials: For the realization of this narrative review were selected articles from 2000 to 2013, consulting the SciELO database using the following descriptors: “anemia”, “blood donor”, “blood”, “iron deficiency”. Results: There were used 22 articles. They reported low levels of erythrocyte indices (Hb <12g / dl, hematocrit <36%, VCM: 84 to 99 of mm³ HCM 26 to 32pg, MCHC: 31 to 36 g / dl) donors blood indicates the presence of anemia nutritional iron deficiency. Conclusions: All studies indicate analyzed using the erythrocyte indices for the identification of anemia. Therefore, these results show the need for guidance together to donors as to their diet rich in iron before and after the donation, which would decrease the frequency of individuals to candidates unfit for inadequate hematimetric indices.
