FLUXOGRAMA PARA DIAGNÓSTICO PRECOCE, TRATAMENTO E MONITORIZAÇÃO DA DEFICIÊNCIA DE FERRO NA CRIANÇA

Abstract

Iron deficiency anemia is defined as a hemoglobin concentration less than a second standard deviation from the distribution mean for a population of the same sex and age. It is the last event in a progression of negative iron balance, with the stages: negative balance, iron deficiency, and iron deficiency anemia. It is the most common hematologic alteration in the world, especially in developing countries. The main source of iron in the body comes from the red blood cell recycling system, while a smaller portion comes from the diet. Despite this, nutritional deficiency is the main etiology of iron deficiency anemia and iron deficiency in childhood. Iron is essential for several physiological functions and its deficiency, especially in childhood, can compromise mental and physical development. Clinical manifestations usually become detectable in severe deficiency. For this reason, the early diagnosis of iron deficiency is through laboratory tests. It should be performed through screening at 12 months of life. Treatment should be started promptly after diagnosis. Diet is of little value in correcting iron owing to the low bioavailability of iron in most foods. However, preparations containing iron are easily absorbed by the body. Given the severity of this condition, treatment should be monitored using laboratory parameters. This study aims to develop a protocol for screening and monitoring the treatment of iron deficiency anemia to systematize and organize care, bringing better results for the childs development.
