OBJECTIVES: To examine whether there is a difference in the characteristics of the complete blood count after birth in children born with intrauterine growth restriction compared to normal values. It will be examined whether there is a difference in the blood count considering gestational age, history of pregnancy, mode of delivery, and the type of growth restriction and head circumference. STUDY DESIGN: Cross-sectional study with historical data. PARTICIPANTS AND METHODS: The study included 95 newborns (49 boys and 46 girls) born after intrauterine growth restriction treated at the Department of Pediatrics of the General County Hospital Požega, in the period from 31 January 2013 to 9 February 2021. Children born with a birth weight below the 10th percentile for gestational age, parity and sex were taken as children born with IUGR. Demographic and clinical data were collected from available medical records. RESULTS: The majority of children after IUGR, 83 of them (87 %) were born at term. The presence of maternal and fetal comorbidities was not shown to be significant for the change in blood count values. The most significant changes in the blood count of children born after IUGR are lower leukocyte values in preterm infants after IUGR compared to children born at term and after IUGR. Considering the head circumference of infants born after intrauterine growth restriction, changes in blood counts were not significant. Higher erythrocyte values were seen in 32 (34 %) patients, leukocytes in 41 (43 %), hemoglobin was elevated in 29 (31 %) patients, hematocrit in 27 (28 %) patients, MCHC was elevated in 38 (40 %) of patients. CONCLUSION: Children born after IUGR who were born prematurely had lower leukocyte values compared to children who had growth restriction and were born prematurely. Changes in the blood count of newborns after IUGR require the presence of several risk factors. At least one feature of a complete blood count is different from normal values.
