Intravenous Aminophylline for Severe Acute Asthma in Children

Intravenous aminophylline improves lung function in children with a severe asthma exacerbation when added to beeta2-agonists and glucocorticoids but does not reduce the length of hospital stay. Risk of vomiting is significantly increased. Level of evidence: "A"

A Cochrane review [Abstract] 1 included 7 studies with a total of 380 children with severe acute asthma already receiving oxygen, maximised inhaled bronchodilators and systemic glucocorticoids. Aminophylline significantly improved percentage predicted FEV1 compared to placebo at 6-8 hours (8.37% predicted, 95% CI 0.82 to 15.92; 2 trials); the effect was sustained at 24 hours (8.87% predicted, 95% CI 1.25 to 16.50; 2 trials). Improvement in PEF was also significant at 6-8 hours (SMD 0.62, 95% CI 0.04 to 1.2) but not at 24 hours (SMD 0.39, 95% CI -0.51 to 1.30).

Improvements were also seen in symptom scores in favour of aminophylline at 6-8 hours (SMD: -0.42, 95% CI -0.70 to -0.14; 2 trials) but not at 24 hours (SMD -0.13 95% CI -0.52 to 0.25; submaximal subgroup). There was no significant difference in length of hospital stay, symptoms, frequency of nebulisations and mechanical ventilation rates. Vomiting was more likely with aminophylline therapy (RR 3.59, 95% CI 2.15 to 6.33; 5 trials).
