Outcome Measures

Primary Outcomes (1)

  • presence of treatment failure

    Treatment failure was defined as meeting two of the following criteria \[16\]: 1. No change or an increase in respiration rate compared with baseline. 2. No change or an increase in heart rate compared with baseline. 3. Persistence of low SpO2 (\<%92) measurements despite an adequate oxygen flow rate and FiO2 in the HFNC group/oxygen flow rate of 15 L/min in the mask group.

    up to 1 month

Secondary Outcomes (3)

  • total duration of oxygen therapy

    up to 1 month

  • Length of hospital stay day

    up to 1 month

  • time of treatment failure

    up to 1 month

Study Arms (2)

Diffuser-mask group

ACTIVE COMPARATOR

The patients received oxygen therapy (8-15 L/min) from an OxyMask (Southmedic, Inc., Barrie, ON, Canada) to maintain oxygen saturation (SpO2) \> 92%. Oxygen therapy was halted if SpO2 was maintained at a level greater than 92% for more than 4 h. The oxygen flow rate was then decreased to 2 L/min and the patient was monitored while breathing room air.

Device: Diffuser oxygen mask

HFNC group

ACTIVE COMPARATOR

The patients received oxygen therapy at a high flow rate from a Precision Flow nasal cannula (Vapotherm, Inc., Stevensville, MD, USA). We selected a 1.9 mm pediatric cannula, which can dispense 1-20 L/min of oxygen. The initial oxygen flow rate was 1 L/kg/min and the FiO2 was 100%. The initial flow rate was increased by 1 L/kg/min until the SpO2 reached 92%. The initial FiO2 was decreased once the SpO2 was greater than 92% and the oxygen flow rate was maintained. HFNC therapy was halted if SpO2 was maintained at a level greater than 92% for more than 4 h at a FiO2 value of 21%, and the patient was transferred to a ward.

Device: high flow nasal oxygen therapy

Interventions

Oxygen therapy using a high-flow nasal cannula (HFNC) is a high-flow oxygen delivery system that enhances the efficiency of respiration by using high flow rates to clear dead space and provide fresh oxygen. This system supplies oxygen at a high flow rate through a loose nasal cannula.

HFNC group

diffuser mask is a low-flow delivery system, which is capable of delivering up to 90% of the fraction of inspired oxygen (FiO2) with low CO2 retention. In this system, the FiO2 can be adjusted by modifying the flow velocity to deliver the quantity of oxygen that the patient requires. Oxygen is supplied to the patient in a jet that flows from a device mounted on the oxygen mask. This ensures that a high concentration of oxygen is provided at a low flow rate.

Eligibility Criteria

Age1 Month - 24 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Included patients were aged between 1 and 24 months and had been diagnosed with moderate or severe acute bronchiolitis. They were admitted to the ICU, requiring supplemental oxygen, because their SpO2 measurements were less than 94% while breathing room air.

You may not qualify if:

  • Any patients requiring immediate respiratory support (non-invasive or invasive mechanical ventilation, altered mental status, or apnea at presentation), those already admitted to the ICU due to respiratory failure, those with underlying chronic lung disease or cardiovascular disorders, those with obstructions of the upper respiratory tract, and those with cranial malformations were excluded.
