Introduction: Late preterm infants (LPT) are born at a gestacional age between 34 and 36 weeks. They have greater vulnerability and morbidity compared with term newborn, particularly respiratory pathology.
Objective: Evaluate the respiratory morbidity of late preterm infants in hospital Cuf Descobertas (HCD) between 2008 and 2012.
Methods: Review of all medical records of late preterm births, analysing particulary the respiratory complications requiring hospitalization to the Special Care Unit.

Conclusion: Late preterm had higher morbidity than term infants. They were hospitalized in 31% of cases compared to 8,5% of all newborns. On admission, respiratory disease was the most prevalent, in 42% of cases. The disease was severe enough requiring ventilatory support in 22% of hospitalized LPT. One had a neuromuscular disease and died.
