Short-Term High-Flow Nasal Cannula for Moderate to Severe Bronchiolitis Is Effective in a General Pediatric Ward.

We examined the clinical and physiological benefits of heated humidified high-flow nasal cannula (HHHFNC) in treating pediatric bronchiolitis in a general pediatric ward. Children aged 0 to 2 years, hospitalized with moderate to severe bronchiolitis, were connected to HHHFNC. Each child was evaluated at 4- to 10-hour intervals, both on and off the device, using the Wang et al Bronchiolitis Severity score and transcutaneous CO2 monitor. Sixteen children were included in the final analysis. The Bronchiolitis Severity score improved by 3 points during the first and second intervals (P = .001). Transcutaneous CO2 values were reduced by an average 8.7 mm Hg (P = .001). No adverse effects were noted in children connected to the device. The HHHFNC device used in a general pediatric ward setting served as a safe and efficacious tool in treating moderate to severe bronchiolitis. Immediate clinical and physiological improvement was observed and maintained 1 to 4 hours after disconnection from the device.
