Shein SL, et al. - Experts aspired to identify relationships between use of ipratropium and/or intravenous magnesium and outcomes of children hospitalized with acute asthma exacerbations and treated with continuous albuterol. In children with severe asthma hospitalizations that required continuous albuterol therapy, ipratropium and magnesium were both often used. Magnesium use was correlated with unfavorable outcomes, possibly reflecting preferential treatment to patients with more severe cases and differing practices between centers.
