Compatibility of rapid enteral feeding advances and noninvasive ventilation in preterm infants-An observational study.

Abstract

To evaluate safety and clinical outcome of rapid enteral feeding advances in preterm infants <1500 g birthweight (BW). In this single-center retrospective cohort study, 293 preterm infants born during 2015-2018 were comparatively analyzed before (n = 145) and after (n = 148) the implementation of a rapid enteral feeding protocol with daily milk increments of 20-30 ml/kgof body weight. Major outcome parameters were focused towardpulmonary morbidities and nutritional variables. Preterm infants in the rapid feeding advancement group were more successfully stabilized on noninvasive ventilation (p < 0.001) never requiring mechanical ventilation. Duration of respiratory support (0.465) and frequency of bronchopulmonary dysplasia (BPD) (p = 0.341) and severe BPD (0.273) did not differ between both groups. Furthermore, patients in the rapid feeding group achieved full volume feedings faster (p < 0.001), regained BW earlier (p = 0.009), and displayed significantly improved somatic growth at 36 weeks gestational age (p < 0.001). There was no increased risk for further morbidities of prematurity including feeding intolerance, necrotizing enterocolitis (NEC), and focal intestinal perforation. Rapid enteral feeding advancements in preterm infants <1500 g BW are safe and do not impede stabilization on noninvasive ventilation.
