PURPOSE : To determine the effectiveness of chest physiotherapy (percussion, postural drainage and suctioning) in non-ventilated paediatric bronchiolitis patients aged 0 to 24 months. BACKGROUND : The field of paediatric cardiopulmonary physiotherapy has a limited evidence base and findings from this study may assist in choosing effective treatment options. METHODS : The following databases were reviewed by making use of a specified search strategy: African Health Line, CINAHL, Cochrane, Ebsco-Host, E-theses/dissertations, PEDro, Medline Ovid, Sabinet, Science Direct and Up-To-Date. Pre-set eligibility criteria were applied to the article title and/or abstract and full-text. Appraisal tools (CASP and PEDro scale) were used to evaluate and score the included studies. A qualitative synthesis was done as a meta-analysis was not possible. RESULTS : Evidence does not support routine chest physiotherapy in uncomplicated viral bronchiolitis in non-ventilated paediatric patients. Chest physiotherapy does not have a significant influence on various outcomes measures. CONCLUSION : Routine chest physiotherapy should not be prescribed for non-ventilated paediatric patients with bronchiolitis.
