ObjectiveTo analyse the prognostic factors for complications in children with bronchiolitis admitted to a pediatric intensive care unit (PICU).Patients And MethodA retrospective study was performed on children with bronchiolitis admitted into a PICU between 2000 and 2006. Univariate and multivariate analysis were performed to study the prognostic factors of complications, mechanical ventilation requirements, mortality and PICU stays of more than 15 days.ResultsA total of 110 patients were studied, of whom 72 (65.5%) had high risk factors: prematurity (39.1%), cardiac disease (38.2%) and bronchopulmonary dysplasia (16.3%). A total of 82.7% of patients had complications; 26% need invasive mechanical ventilation and the mortality was 3.6%, and 16.4% stayed in PICU for more than 15 days. Factors associated with mechanical ventilation were the clinical Wood-Downes score and heart disease. A weight less than 5 kg was associated with complications; heart disease and invasive mechanical ventilation were associated with a longer PICU stay; prematurity and mechanical ventilation were associated with mortality.ConclusionsChildren with bronchiolitis admitted into the PICU had a high frequency of complications, often needed mechanical ventilation and had long stays in the PICU, but the mortality is low. The best prognostic factors on admission into the PICU were the acute respiratory insufficiency score, the presence of heart disease and were premature at birth.
