ANEMIA NEONATAL. TRES PRESENTACIONES CLÍNICAS.

Anemia is defined as the reduction of red blood cells, hemoglobin and/or hematocrit. the values considered as normal for haemoglobin and haematocrit depend on gestational age and days of life. this review, will focus on anemia presenting during the first days of life. In general, in the first week of life the normal values of haemoglobin and haematocrit should be greater than 15 gr/dl and 45% respectively. the causes of neonatal anemia can be: blood loss, destruction of red blood cells and lack of production. three different clinical cases of neonatal anemia are reported, the last of which is a rare clinical case of genetically induced arregenerative anemia. A practical approach to the diagnostic process of neonatal anemia is presented. [ABSTRACT FROM AUTHOR]
