Background
In pediatric intensive care units, non-invasive respiratory support methods are increasingly used, but there haven’t been large trials comparing two popular methods: continuous positive airway pressure (CPAP) and high-flow nasal cannula therapy (HFNC).
Objective
The goal is to compare HFNC with CPAP to see if HFNC is just as effective for children needing respiratory support, particularly looking at how quickly they can stop needing help with their breathing.
Study Design
This research involved two separate trials across 25 hospitals in the UK, focusing on critically ill children who needed respiratory support either due to illness or after being taken off a ventilator.
Participants
Children who needed respiratory support were enrolled in either a step-up trial (for acute illness) or a step-down trial (post-extubation).
Interventions
Participants received either HFNC, which delivers air based on the child’s weight, or CPAP, which uses a specific pressure setting.
Main Outcomes
The primary outcome measured was the time until patients could breathe without assistance. Additional measures included the cost-effectiveness of treatments, mortality rates, and overall quality of life.
Results Summary
In the step-up trial with 600 children, those using HFNC took about 52.9 hours to stop needing support, while those on CPAP took about 47.9 hours. HFNC also resulted in less sedation use and shorter hospital stays.
In the step-down trial with 600 children, HFNC took about 50.5 hours compared to CPAP’s 42.9 hours. However, mortality was higher in the HFNC group at 5.6% compared to 2.4% for CPAP.
Limitations
The study was not blinded, which may influence results, and included children with varying illnesses.
Conclusions
For critically ill children needing respiratory support, HFNC was effective but showed higher mortality after extubation. More work is needed to understand treatment failures and improve care strategies.
Future Work
Future research will focus on identifying risk factors for treatment failure, comparing different support approaches, and analyzing the reasons behind the increased mortality with HFNC.
