In this prospective multicenter study of children younger than 2 years with bronchiolitis, multiple factors were associated with longer ED LOS. These factors suggest the following steps to help shorten ED LOS: optimizing translation services, improving primary care provider rates, enhancing overnight patient flow, forgoing chest x-rays, and developing evidence-based admission criteria.

In this study, we did not find a significant increase in metabolic stress, measured by serum lactate. Using propofol for short-duration procedural sedation may not carry similar risks for propofol infusion syndrome to those for long-duration/high-dose infusion therapy.

We compared the use of cough and cold medications in two multicenter studies of young children hospitalized with bronchiolitis before and after the 2008 Food and Drug Administration cough and cold medications advisory. Although cough and cold medications use decreased after the advisory, nearly 20% of children age 12–23.9 months with severe bronchiolitis received cough and cold medications.
