Repercussão da displasia broncopulmonar sobre a prontidão e performance alimentar de recém-nascidos pré-termo

Abstract

Introduction: The Bronchopulmonary dysplasia (BPD) is a major chronic respiratory condition found in newborn preterm infants (PTI) of gestational age and reduced birth weight associated with immaturity and diminished alveolarization. The transition from tube to oral feeding in children who develop dysplasia during the neonatal period is difficult to manage, requiring special attention when the oral starts. Objective: To evaluate the repercussion of DBP on the feeding readiness and the feeding performance of PTI. Methods: The sample was consisted to 53 children assigned to a group with BPD (G1=14) and a group without BPD (G2=39). In the first oral feed was performed the evaluation of readiness, or oral feeding ability, by the Fujinaga (2005) and Lau & Smith (2011) protocols. The feed performance was evaluated through proficiency, transfer rate of milk and feed performance as well the occurrence of signs of stress in the first feeding orally. Was also evaluated the time to attainment of full orally. Results: Presence of oral skill to begin oral feeding was observed in 64,3% and 21,4% of PTI with BPD, according to the protocols of Fujinaga (2005) and Lau & Smith (2011), respectively. In the group without BPD, 69,2% and 48,7% had skill, according Fujinaga (2005) and Lau & Smith (2011), respectively. Regarding food performance, the PTI with BPD showed worse results, both as to the proficiency and performance feed (p<0,05), as well as in relation to signs of stress. The feeding transition occurred at 12,9 (±10,5) days in children without BPD and 26,8 (±13,8) days in those with BPD (p=0,0002). Conclusion: At the time of release of oral feed, most preterm infants with BPD was not able to feed, according to the protocol of Lau & Smith (2011). As consequence the dysplasic children showed lower feeding performance and greater occurrence of signs of stress in first oral feed. The time required to attainment of full oral feeding was significantly higher in PTI with BPD.
