Factors Associated To The Gestational Age Of Prematuros Inhibited In A Neonatal Intensive Therapy Unit

Objective: To describe factors associated with the gestational age of premature infants admitted to the Intensive Care Unit. Methods: A cross-sectional study with preterm infants referred to the discharge of the Unit. Results: 66 preterm infants, 59% boys, mean 32 gestational weeks, 26% preterm infants, 51% with adequate gestational age at birth participated. 38% of pregnant women presented pre-eclampsia, 18% had gestational diabetes. There was association of preterm groups with birth weight (p = 0.000), length of hospital stay (p = 0.000), time of invasive mechanical ventilation (p = 0.000), total oxygen time (p = 0.000), transfusion requirement (0.019) and use of surfactant (0.003). Among late and moderate preterm infants, there was a significant increase in the frequency of small infants for gestational age at discharge (p = 0.046 and p = 0.021). Conclusion: Pre-eclampsia was the most prevalent complication among pregnant women. Gestational diabetes was more frequent at delivery before 34 weeks. Restriction of extrauterine growth was observed at the time of discontinuation of the unit.
