CPAP and HFNC Show Similar Reintubation Rates After Pediatric Extubation
A retrospective cohort study using Australian and New Zealand pediatric intensive care registry data compared CPAP with HFNC after extubation in children receiving noninvasive support. After propensity matching, reintubation rates were similar, while CPAP use was associated with longer respiratory-support duration and longer PICU stays.
- Reintubation rates were similar with CPAP and HFNC.
- CPAP was associated with longer postextubation support.
- HFNC was associated with shorter PICU and hospital stays.
- Retrospective registry data cannot establish causation.
Researchers analyzed Australian and New Zealand Pediatric Intensive Care registry data from 2014–2021, covering 31,910 extubation episodes in 23,930 children. Among 7,156 children who received noninvasive respiratory support after extubation, propensity matching produced 1,418 pairs treated with CPAP or high-flow nasal cannula (HFNC). The primary outcomes were reintubation and duration of postextubation support; secondary outcomes included PICU and hospital length of stay and in-hospital mortality.
Reintubation occurred in 107 children receiving CPAP (7.6%) and 115 receiving HFNC (8.1%), with no identified association between support type and failure (rate ratio 0.93; 95% CI, 0.72–1.25). Median support duration was 72 hours with CPAP versus 30.5 hours with HFNC, a median difference of 41.5 hours (95% CI, 37.7–45.2). Median PICU stay was also longer with CPAP: 10.2 versus 7.1 days. HFNC was associated with shorter PICU and hospital stays; mortality was not associated with support type.
These observational findings do not establish that one approach causes shorter support or hospitalization. Propensity matching addresses measured differences but cannot eliminate residual confounding, and the results apply to children in the registry who required noninvasive support after extubation.
In practice
For children in intensive care who require noninvasive respiratory support after extubation, this registry analysis found no identified difference in reintubation between CPAP and HFNC after propensity matching (7.6% vs 8.1%). CPAP was associated with longer support duration and PICU stay, while HFNC was associated with shorter PICU and hospital stays. These findings may inform discussion of postextubation support, but they do not establish that HFNC causes better outcomes; residual confounding in this retrospective study remains possible.
