[Short-term complications of late preterm infants]

Area of Science:

• Neonatal Medicine
• Perinatology
• Pediatric Outcomes Research

Context:

• Late preterm infants (34-36 weeks gestation) exhibit physiological immaturity compared to term infants.
• This immaturity increases their susceptibility to morbidity and mortality.
• Local factors can influence health outcomes in premature infants.

Purpose:

• To determine the short-term medical problems in late preterm infants within a specific hospital setting.
• To compare the morbidity and mortality data between late preterm and term infants.
• To identify risk factors associated with late preterm birth.

Summary:

• A retrospective study compared 769 late preterm infants with 1460 term infants (≥34 weeks gestation).
• Late preterm infants had higher rates of assisted reproduction, twin pregnancy, cesarean delivery, and preeclampsia.
• Increased hospitalization (6x), neonatal intensive care admissions (2x), longer hospital stays, and greater neonatal respiratory morbidity and jaundice were observed in late preterm infants. Surfactant, oxygen, and respiratory support use was also higher. No significant differences in hypoglycemia or mortality were found.

Impact:

• Late preterm infants constitute a distinct risk group requiring specialized care resources.
• Findings underscore the need for targeted interventions and resource allocation for this population.
• The study provides local data to inform clinical practice and improve outcomes for late preterm infants.
