Abstract
Objective: To evaluate the hematologic profile of newborns of a neonatal intensive care unit in Teresina - PI. Methodology: We analyzed the hemograms contained in electronic medical records or hospital medical history of neonates admitted to the Neonatal Intensive Care Unit. The newborns were classified according to sex and age in days and hematological data were collected through the hematologic counter Sysmex® Series-XS 800i. The red series (erythrogram), white series (leukogram) and platelets (plaquetogram) were analyzed. Results: The analysis of the hemograms of the newborns showed a prevalence of female neonates (93.3%) aged 0-3 days (50%) when they underwent hemogram. In the erythrogram, leukogram and plaquetogram, there was a tendency to normality of the values found, showing changes in hematimetric indexes (62%), HCM (68.6%) and RDW (92%), and prevalence of lymphopenia (57, 3%). Conclusion: The hemogram of the newborn offers numerous information and its interpretation may vary according to the age and other characteristics inherent to the neonate. However, the reference values for this age group are difficult to obtain.
