Efeitos da fisioterapia respiratória na saturação periférica de oxigênio, frequência cardíaca e frequência respiratória de recém-nascidos pré-termo submetidos à ventilação não-invasiva

Abstract

Introduction: The newborn preterm infants (PTI) may have respiratory complications due to immaturity of the pulmonary system, a major cause of morbidity and mortality in this period, the respiratory therapy is an effective remedy in the prognosis of prematurity. Objective: To analyze the immediate effects of respiratory physiotherapy on oxygen saturation (SpO2), heart rate (HR) and respiratory rate (RR) of preterm infants undergoing noninvasive ventilation (NIV). Methodology: The study is a randomized clinical trial consisted of seven infants who received NIV in increased expiratory flow (AFE) and physiotherapy (FRC) divided into two groups (A and B). Descriptive analysis of variables to compare mean values before and after the maneuvers with a significance level of 5%. Results: There was a significant relation with the increase in SpO2 after administration of AFE and decrease in f after the FRC. Conclusion: The results of this study suggest that the maneuvers can be safely applied in preterm infants, because they showed no deleterious hemodynamic effects that contributed to an increase in SpO2 and reduction of f the patients who participated in the sample.
