To investigate the effectiveness of the application of clinical guidelines “Enteral feeding of preterm infants” in infants below 32 weeks’ gestation. Material and methods. The study comprised 114 extremely preterm infants born before (2013-2014, group 1, n=53) and after (2014-2015, group 2, n=61) introduction of the clinical guidelines. Comparative analysis included breastfeeding frequency, the time of initiation of enteral feeding and achieving enteral feeds up to a volume of 150ml/kg/d, the incidence of necrotizing enterocolitis (NEC), gastrointestinal dysfunction, gastric bleeding, the use of breast milk fortifier, and the dynamics of infant postnatal physical growth. A comparative assessment also included the length of hospital stay, postconceptional age (PCA) and body weight at the time of hospital discharge. Results. After the introduction of clinical guidelines, 47 (77%) children received maternal colostrum on the first day of life. Breastfeeding was initiated significantly earlier: within 1 (1-5) day after birth in group 2 compared with 9 (2-28) days in group 1. Most infants received enteral feeding on the first day of life, though the infants in group 2 were administered it significantly earlier [7.5 hours (3.5-51) vs. 12 (6-144)]. A significant part of the extremely preterm infants was fed with breast milk. Sixteen (30%) infants in group 1 and almost twice fewer children in group 2 [10 (16%)] were on artificial feeding. In group 2, full enteral feeding was achieved significantly earlier than in group 1 [12 days (6-48) vs. 18.5 (13-47)], while the incidence of NEC in group 2 decreased 1.7-fold (14.8% vs. 24.5%). By 36 weeks’ PCA, the infants in group 2 had significantly higher body weight than babies in group 1 [2220 g (1420-2818) vs. 2050 g (950-3190)]. Conclusion. The clinical implementation of the guidelines “Enteral feeding of preterm infants” has resulted in significantly higher feeding efficiency in extremely preterm babies.
