RESUMO

The objective of this study was to compare neonatal morbidity and mortality between late-preterm infants (gestational age at birth: 34 to 36 weeks and 6 days) with and without fetal growth restriction (FGR). A longitudinal study was conducted between October 2004 and October 2006 involving 50 pregnant women with pre-term delivery associated with FGR (group I) and 36 women with spontaneous preterm delivery not associated with FGR (group II). The following postnatal outcomes were evaluated: weight and gestational age at birth, cesarean section rate, 5-minute Apgar score, umbilical artery pH at birth, and need for and duration of orotracheal intubation and hospitalization in the neonatal intensive care unit (NICU), as well as the presence of respiratory distress syndrome (RDS), sepsis, thrombocytopenia, hypoglycemia, intracranial hemorrhage (ICH) and jaundice, need for phototherapy, length of hospital stay, and occurrence of death. The chi-square test, Fishers exact test and nonparametric Kruskal-Wallis test were used for statistical analysis, adopting a level of significance of 5%. Gestational age was similar in groups I and II, with a mean of 35.5 weeks in both groups. A higher frequency of the following adverse postnatal outcomes was observed in group I: lower birth weight (p<0.001), higher incidence of cesarean section (92% versus 25% in group II; p<0.0001), greater need for NICU treatment (58% versus 33%; p=0.041), longer hospital (p<0.001) and NICU stay (p<0.001), higher frequency of ICH (12% versus 0; p=0.037) and hypoglycemia (24% versus 6%; p=0.047), and longer duration of phototherapy (p=0.005). No differences in Apgar scores, cord pH, orotracheal intubation, RDS, thrombocytopenia, sepsis, or jaundice were observed between groups. There were no cases of hyaline membrane disease, bronchopulmonary dysplasia, pulmonary hemorrhage, or neonatal death. In conclusion, the group of late-preterm infants with FGR presented more neonatal complications than the group without FGR
