Positive pressure ventilation in the weaning of preterm newborns.

摘要: BACKGROUND Weaning from invasive mechanical ventilation (IMV) of preterm newborns (PTNB) is one the critical stages life support in neonatal intensive care unit (NICU). Noninvasive positive pressure (NPPV) has been used to facilitate weaning IMV and includes continuous airway (CPAP) without or with inspiratory (Bilevel NPPV). Nevertheless, there little information about their adherence success rate during process. METHODS In this retrospective cohort study, data patients admitted a NICU northeast region Brazil were analyzed. Sample was composed PTNB submitted divided two groups according strategy adopted: Bilevel NPPVor NCPAP. failure defined as returning within less than 48h after extubation. RESULTS Fifty-seven included. Majority female, had caesarean delivery, very low weight upon birth (760-1,480g) hypoxemia scores (Apgar) <7 first minute. Respiratory distress syndrome occurred 56.7% whilst respiratory infections 35.1% patients. NPPV most chosen modality weaning. No difference found between NCPAP (p=0.17). CONCLUSIONS application noninvasive for similar
