Respiratory support in paediatric patients with bronchiolitis: a systematic review and meta-analysis

Resumo original em inglês

O que aconteceu

Recent evidence suggests that high-flow nasal cannula (HFNC) may confer better clinical outcomes compared with other respiratory support modalities in paediatric patients with bronchiolitis.

We performed a literature search up to 21 January 2024 on PubMed, Scopus, Cochrane Library, Embase, Cumulative Index to Nursing and Allied Health Literature, World Health Organization International Clinical Trials Registry Platform and Clinicaltrials.gov. Randomised controlled studies including paediatric patients aged ≤24 months with bronchiolitis comparing the use of HFNC versus low-flow nasal cannula (LFNC) or continuous positive airway pressure (CPAP) were included. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Random-effect modelling was used to estimate pooled effects.

O que encontraram

18 studies with 4094 patients were included. HFNC did not reduce the need for mechanical ventilation compared to LFNC (risk ratio 0.69, 95% CI 0.33-1.44; p=0.32) or CPAP (risk ratio 0.90, 95% CI 0.65-1.24; p=0.52). HFNC resulted in less treatment failure compared to LFNC (risk ratio 0.44, 95% CI 0.23-0.87; p=0.02), whereas there was no difference compared to CPAP (risk ratio 1.28, 95% CI 0.90-1.80; p=0.17). HFNC was associated with significant reduction in length of paediatric intensive care unit (PICU) stay compared to LFNC (mean difference (MD) -0.40 95% CI -0.78- -0.02; p=0.04), but not compared to CPAP (MD -0.24, 95% CI -0.91-0.43; p=0.47).

Por que isso importa

HFNC significantly reduced treatment failure, length of PICU stay and total oxygen therapy duration compared to LFNC. No differences between HFNC and CPAP in primary and secondary outcomes. HFNC could be considered as initial treatment modality in paediatric patients with bronchiolitis, especially in patients requiring escalation of treatment from LFNC.
