Cochrane Database Syst Rev. 2024 Oct 2;10(10):CD012067 http://doi.org/10.1002/14651858.CD012067.pub3 Clinical QuestionAsthma is the most common chronic disease in children and accounts for 2.3% of pediatric hospitalizations. This condition has a major medico-economic impact, affecting both children’s quality of life and healthcare costs. In 10–12% of cases, intensive conventional treatment based on bronchodilators and corticosteroids is insufficient, and management must be escalated to endotracheal intubation and invasive mechanical ventilation. Some observational studies suggest that non-invasive positive pressure ventilation (NPPV) could reduce the need for intubation. Bottom LineTo assess the effects of NPPV combined with conventional treatments compared with conventional treatments alone in children with moderate to severe acute asthma, in terms of mortality, occurrence of serious adverse events (SAEs), length of stay in intensive care, and asthma symptom scores during the acute phase. Main ResultsNo all-cause mortality was reported in either group. Only one randomized study assessed SAEs, namely the intubation rate. Bilevel positive airway pressure (BiPAP) may substantially reduce the intubation rate and appears to shorten the length of stay in intensive care, but these results are very uncertain (very low level of evidence). Acute asthma symptoms score was evaluated in only two studies using different outcome measures, which did not allow meta-analysis. BiPAP may have a beneficial effect on the score, but this result is also very uncertain (very low level of evidence). CaveatsCurrent data are limited, with small sample sizes, resulting in very uncertain evidence and preventing a comprehensive evaluation of the benefits and risks of NPPV in children with acute asthma. Large, well-designed randomized controlled trials with low risk of bias are therefore needed.In the trials included in the review, the positive end-expiratory pressure (PEEP) was relatively low (4–5 cmH₂O), whereas pressures of 8 to 12 cmH₂O may be necessary to compensate for intrinsic PEEP.
