Noninvasive Ventilation and Rapid Enteral Feeding Advances in Preterm Infants-2-Year Follow-Up of the STENA-Cohort.

The importance of nutritional supply for somatic growth and neurodevelopmental outcome in very-low-birthweight infants is an established medical strategy for reducing long-term morbidities. Our cohort study on rapid enteral feeding advances using a standardized protocol (STENA) previously demonstrated a 4-day reduction of parenteral nutrition. STENA did not impede the success of noninvasive ventilations strategies but significantly less infants required mechanical ventilation. Most importantly, STENA resulted in improved somatic growth at 36 weeks of gestation. Here, we evaluated our cohort for psychomotor outcomes and somatic growth at 2 years of age. n = 218 infants of the original cohort were followed-up (74.4%). Z-scores for weight and length did not differ but the benefits of STENA for head circumference persisted until the age of 2 years (p = 0.034). Concerning the psychomotor outcome, we neither found any statistically significant differences in the mental developmental index (MDI) (p = 0.738), norin the psychomotor developmental index (PDI) (p = 0.122). In conclusion, our data adds important insights on the topic of rapid enteral feeding advances and confirms the safety of STENA with respect to somatic growth and psychomotor outcome measures.

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

AIM: To evaluate safety and clinical outcome of rapid enteral feeding advances in preterm infants <1500 g birthweight (BW). METHODS: 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/kg of body weight. Major outcome parameters were focused toward pulmonary morbidities and nutritional variables. RESULTS: 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. CONCLUSION: Rapid enteral feeding advancements in preterm infants <1500 g BW are safe and do not impede stabilization on noninvasive ventilation.
