Abstract

Objective. To investigate the course of the neonatal period and the development of pathological conditions at birth and in the first year of life among late preterm neonates. Material and methods. A total of 568 case histories of babies born at 340/7 to 366/7 weeks’ gestation in the period from 01.10.2013 to 31.12.2015 were retrospectively analyzed and 60 late preterm infants were selectively followed up for their development during the first year of life at the Academician V.I. Kulakov Research Center of Obstetrics, Gynecology, and Perinatology, Ministry of Health of Russia. Results. The investigation showed that 28.9% of the late preterm babies needed treatment in an intensive care unit (ICU). 51.4% required treatment in a pathology unit for neonates and premature babies (PUNPB). 45.9% of the late premature infants were discharged home from the neonatal unit (NU). The mean length of hospital stay in ICU, PUNPB, and NU was 5.4±4.2, 0.8±4.7, and 5.2±1.8 days, respectively. The severity of prematurity-related complications in the followed-up infants was proportional to gestational age (p < 0.005). The follow-up of the late preterm infants revealed that their vast majority caught up with their full-term peers in terms of physical and psychomotor development during the first six months of life. Conclusion. The investigation confirms the need for increased attention, differentiated approaches to nursing, feeding, and management of infants born at 34-36 weeks’ gestation.
