Abstract

Objective: Assess the characteristics of late pre term newborns admitted in a neonatal intensive care unit. Methods: Descriptive, cross-sectional, retrospective study with all the patients in the neonatal intensive care unit of a university hospital in a mid-size city, between January 2011 and December 2012. Perinatal and neonatal variables were avalued throughout hospitalization. Results: The study population consisted of 330 patients. Newborns under 33 weeks of gestational age accounted for 50% of hospitalizations, late preterm infants, for 27,3% and full-term newborns, for 20%. The majority of the population had adequate weight for gestational age, with a rate of 67.8% among late preterm. Over seventy percent of the general population and those born cesarean; whose primary indication was fetal distress. The main cause of hospitalization for all groups was infant respiratory distress syndrome, accounting for 70% of admissions of late preterm. Sepsis reached 66.7% of this group requiring several therapeutic measures during hospitalization. The mortality rate of late preterm infants was 5.6%, the lowest among groups of gestational age. Conclusion: The need for emergency neonatal care and increased occupancy rate in intensive care units show us the importance of this premature group and warns us that are not functionally "near term" and that their particularities physiological and metabolic put them on a different level to be disregarded at the time of his birth
