Objectives: To compare the effects of retrograde rhinopharyngeal clearance (RRC) with nasopharyngeal aspiration in children admitted with acute viral bronchiolitis (AVB). Methods: This is an experimental, controlled and randomized study in children admitted for AVB up to 12 months old. Patients were divided in aspiration group (AG), submitted to nasopharyngeal aspiration, and clearance group (CG), submitted to RRC technique. In both groups there were three evaluations in the same day (C1, C2, C3), including cardiorespiratory parameters, clinical score of respiratory dysfunction and adverse effects. Results: 100 children were included, 50 in each group, with no statistical difference between the groups regarding the characteristics of the sample. There was a significant reduction in heart rate (HR) in C1 and C2 after 10 and 30 min. Number of episodes of nasal bleeding and vomiting was higher in AG compared to CG. Children classified as moderate showed a significant reduction of retractions and nasal bleeding. AG children´s showed an increase of 6.7% and 19.5% of wheezing and retractions, respectively, while the children of CG showed only 4.6% for both parameters. Conclusion: The use of RRC technique in the clinical management of children with AVB can be an alternative for the clearance of the upper airways, as it showed immediate positive results on the occurrence of complications and signs of respiratory effort compared with the nasopharyngeal aspiration. Children classified with moderate clinical scores appear to be the most benefited.
