COMPARAÇÃO ENTRE O MÉTODO REEQUILÍBRIO TORACOABDOMINAL E A TÉCNICA DE DRENAGEM AUTÓGENA ASSISTIDA SOBRE OS PARÂMETROS FISIOLÓGICOS E DESCONFORTO RESPIRATÓRIO EM RECÉM-NASCIDOS PRÉ-TERMO:ENSAIO CLÍNICO RANDOMIZADO

Abstract

Assisted Autogenous Drainage (DAA) and the Thoracoabdominal Rebalancing (RTA) method assist in the synergism of abdominal muscles and breathing, which facilitates bronchial hygiene and improves respiratory mechanics. The aim of this study was to compare the RTA method with the DAA on physiological parameters and respiratory distress in preterm newborns (PTNB). This is a randomized clinical trial in which 30 PTNB participated, allocated in two groups (DAA and RTA group), submitted to a treatment protocol that used DAA or RTA. The variables analyzed were peripheral oxygen saturation (SpO₂), respiratory rate (RR) and heart rate (HR) in addition to respiratory distress (DR) by the Silverman Andersen Bulletin (BSA). Data were collected in 2 moments: before randomization and immediately after the end of the protocol. The HR of PTNBs, immediately after, submitted to AAD decreased significantly in relation to the RTA group (p = 0.040). For the variables SpO₂, RR and BSA score, there was no difference between the experimental groups in any of the evaluated moments. On the other hand, in the intra-group comparison, SpO₂ increased (DAA: p = 0.002; RTA: p = 0.004) and FR decreased (DAA: p = 0.015; RTA: p = 0.017) significantly. Thus, the data show that the RTA and DAA do not differ with respect to the variables analyzed in this study, but are safe and have beneficial results in the SpO₂ and RF of PTNB
