Aim of the study was to determine presence and incidence of perinatal risk in the newborns presenting with the
signs of IUGR or hypotrophy <5% during a 3-year period, and in this way to point the significance of intrauterine diagnostics and special screening during the labor as to reduce the incidence of these factors. Methods: There were 18412 deliveries at the Department of Obstetrics and Gynecology in Novi Sad during the 3-year period out of which number, 560
(3.04%) newborns with IUGR or intrauterine hypertrophy <5%. Results: In the investigated population of 560 newborns
with IUGR or hypertrophy <5%, the following factors of perinatal risk have been recorded: manifest pathological cerebral
signs in 30 cases ( 5.36%), convulsive crises in 6 (1.07%), the crises of apnea and cyanosis in 10 (1.78%), intracranial hemorrhage in 17(3.03%), hyperbilirubinemia in 25 (4.46), hemolytic disease in 6 cases (1.07%), hypoglycemia in 1(0,18%),
disorders of pulmonary ventilation in 26 cases (4.64%) whereas congenital anomalies were evidented in 19 ( 3.39%)
newborn infants. Exanguination transfusion was administered in 4 (0.71%) and transfusion in 9 (1.61%) newborns with
IUGR, i.e. intrauterine hypotrophy <5. Conclusion: The results of investigation show the significant presence of perinatal
risk factors in the population of the newborns with IUGR leading to the increased morbidity in later periods of life.
