Abstract：
One of the urgent problems of nursing premature babies is the timely prediction, diagnosis and treatment of anemia, the frequency of which reaches 90%. Of particular importance is the study of reticulocytic blood parameters in deep-premature newborns, since the correct assessment of hemograms is crucial in the management of this category of children. To determine the characteristics of red blood cells and reticulocyte parameters of venous blood hemogram in premature newborns 24-32 weeks of gestation in the dynamics of the neonatal period. 111 newborns were examined at 24-32 weeks of gestation in the early neonatal period (on day 3-7) and at the age of 1 month of life. Along with standard diagnostic procedures, in accordance with current clinical recommendations and standards, 28 parameters of erythrocyte and reticulocyte hemogram parameters were determined for children. Venous blood was examined using an automatic hematological analyzer ADVIA 2120i, Siemens, USA. In deep-premature newborns in the early neonatal period, there is a high activity of erythropoiesis, respectively, the severity of respiratory and metabolic disorders with rejuvenation of reticulocytic subpopulations. Negative values of Delta hemoglobin were found against the background of a decrease in the average amount of hemoglobin in reticulocytes in children 24-27 weeks of gestation, which characterizes the lowest values of iron availability for erythropoiesis in this category of newborns. It is shown that a decrease in reticulocyte counts and normochromia in all examined newborns by the age of one month are accompanied by high levels of immature reticulocyte fraction, while a third of children still have limited iron availability for erythropoiesis.
