[Consensus conference on acute bronchiolitis (I): methodology and recommendations].
The recommendations of the Consensus Conference "Diagnostic and Therapeutic Management of Acute Bronchiolitis" are presented. Evidence on the frequency of bronchiolitis in the general population and risk groups, risk factors and markers of severe forms, severity scores and the clinical-etiological profile is summarized. The commonly used diagnostic tests are ineffective in the management of the disease; oxygen saturation measurement is considered necessary only in the initial assessment or to monitor changes in patients with respiratory distress. Other tests such as chest radiograph, rapid diagnostic tests for respiratory virus infection and screening tests for bacterial infection should be used only very selectively. There is sufficient evidence on the lack of effectiveness of most interventions tested in bronchiolitis. Apart from oxygen therapy, fluid therapy, aspiration of secretions and ventilation support, few treatment options will be beneficial. Only in moderate-severe bronchiolitis would it be justified to test a treatment with inhaled bronchodilators (salbutamol or epinephrine) with or without hypertonic saline solution. Heliox and non-invasive ventilation techniques could be used in cases with respiratory failure, methylxanthine in patients with apnea and surfactant in intubated critically ill patients. No treatment has proved effective in preventing persistence or recurrence of post-bronchiolitis symptoms. As for prevention of bronchiolitis, only palivizumab slightly reduces the risk of admissions for lower respiratory infections by respiratory syncytial virus, although its high cost justifies its use only in a small group of high-risk patients.
