Previous issue date: 2015-01-20 / 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. / Objetivos: Comparar os efeitos da desobstru??o rinofar?ngea retr?grada (DRRI) com a aspira??o nasofar?ngea em crian?as internadas com diagn?stico de bronquiolite viral aguda.
M?todos: Estudo do tipo experimental, controlado e randomizado, em crian?as internadas por BVA com at? 12 meses de idade. Os pacientes foram divididos em grupo aspira??o (GA), submetido ? aspira??o nasofar?ngea, e grupo desobstru??o (GD), submetido ? t?cnica de DRRI. Em ambos os grupos foram realizadas tr?s avalia??es, no mesmo dia (C1, C2, C3), incluindo par?metros cardiorrespirat?rios, escore cl?nico de disfun??o respirat?ria e presen?a de efeitos adversos.
Resultados: Foram inclu?das 100 crian?as, sendo 50 em cada grupo, sem diferen?a estat?stica entre os grupos quanto ? caracteriza??o da amostra. Houve redu??o significativa da frequ?ncia card?aca (FC) na C1 e C2 ap?s 10 e 30 min. O n?mero de epis?dios de sangramento nasal e v?mito foi maior no GA em rela??o ao GD. Crian?as classificadas como moderadas apresentaram redu??o significativa de tiragem e sangramento nasal. Crian?as do GA apresentaram um aumento de 6,7% e 19,5% de sibil?ncia e tiragem, respectivamente, enquanto nas crian?as do GD foi de apenas 4,6% para ambos os par?metros.
Conclus?o: A utiliza??o da t?cnica de DRRI no manejo cl?nico de crian?as com BVA pode ser uma alternativa para a desobstru??o de vias a?reas superiores, pois mostrou resultados imediatos positivos sobre a ocorr?ncia de complica??es e sinais de esfor?o ventilat?rio em compara??o com a aspira??o nasofar?ngea. Crian?as classificadas com escore cl?nico moderado parecem ser as mais beneficiadas.
