Insights
Heated humidified high-flow nasal cannula (HHHFNC) effectively treated pediatric bronchiolitis, improving severity scores and reducing CO2 levels. This safe and beneficial treatment showed sustained results in young children.
Area of Science:
- Pediatrics
- Respiratory Medicine
- Medical Devices
Background:
- Bronchiolitis is a common respiratory infection in infants and young children.
- Current treatments may not always be sufficient for moderate to severe cases.
- Heated humidified high-flow nasal cannula (HHHFNC) is an emerging therapy for respiratory distress.
Purpose of the Study:
- To evaluate the clinical and physiological benefits of HHHFNC in pediatric bronchiolitis.
- To assess the safety and efficacy of HHHFNC in a general pediatric ward setting.
Main Methods:
- A study involving 16 children aged 0-2 years with moderate to severe bronchiolitis.
- Patients were treated with HHHFNC and evaluated using the Wang et al Bronchiolitis Severity score and transcutaneous CO2 monitoring.
- Assessments were conducted at 4- to 10-hour intervals, both on and off the device.
Main Results:
- Significant improvement in the Bronchiolitis Severity score by 3 points (P = .001).
- Average reduction of 8.7 mm Hg in transcutaneous CO2 levels (P = .001).
- No adverse effects were reported during HHHFNC use.
Conclusions:
- HHHFNC is a safe and effective treatment for moderate to severe pediatric bronchiolitis in a general ward.
- The therapy led to immediate clinical and physiological improvements.
- Benefits were sustained for 1 to 4 hours after device disconnection.
Abstract:
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.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
