IUGR, EVENT, INTRAUTERINE GROWTH RESTRICTION, PATHOLOGY, PREMATURE RUPTURE OF MEMBRANES
Abbreviations: CRIB II, Clinical Risk Index for Babies II; IUGR, intrauterine growth restriction; PROM, premature rupture of membranes.SI conversion factor: To convert hemoglobin from grams per deciliter to grams per liter, multiply by 10.Categorical variables (sex, twin, basal obstetric pathology, and antenatal steroids) are reported as No. (%). Continuous variables (gestational age at birth, birth weight, Apgar score, basal CRIB II score, and hematologic parameters at birth) are reported as median (IQR).Scores range from 0 to 10, with higher scores indicating a healthier assessment 1 minute and 5 minutes after birth.Scores range from 0 to 27, with lower scores indicating a better prognosis.The 17 neonates included in the analysis received 42 total transfusions, of which 22 were A-RBCs and 20 were CB-RBCs. For each patient, the type of blood product and the progressive number of the transfusion event are detailed in eTable 1 in
