About

The study aims to compare the efficacy of two different oxygenation methods on decrease respiratory rate, heart rate, and clinical respiratory score in children with moderate to severe bronchiolitis requiring oxygen therapy.

Standard face mask oxygen therapy (St-FMOT)
High-flow nasal cannula oxygen therapy (HFNCOT)

Full description

Bronchiolitis is the most common cause of hospitalization for children under one year of age and, caused by respiratory viruses. Although several medications and interventions studied for bronchiolitis treatment, hydration and oxygenation are the main treatments. High-flow nasal cannula oxygen therapy (HFNCOT) has been widely used to provide respiratory support in children with acute respiratory diseases.

Patients had earlier improvement with HFNCOT to decrease the respiratory rate and respiratory effort than patients with standard low-flow oxygen therapy (SOT).

HFNCOT therapy reduced more effective in heart rate, respiratory effort, and length of supportive oxygen treatment (LOOT) compared with SOT. However, the length of hospital stay (LOS) and feeding ability had better consequences in patients with moderate and severe bronchiolitis treated with HFNCOT.

Another published study shows that in infants with acute bronchiolitis, which required oxygen therapy, there was no significant difference between therapy groups in terms of LOOT, LOS, and admission to the intensive care unit (ICU). HFNCOT was more efficient than SOT and reduced the rate of intubation/invasive ventilation in severe bronchiolitis management. Despite these beneficial effects of HFNCOT, it was not recommended by international guidelines yet. However, well designed, prospective randomized controlled trials are still needed to use this therapy in the wards.

Inclusion criteria

Children aged between 1-24 months applied with moderate and severe bronchiolitis requiring supplemental oxygen were eligible for the study.
The severity of bronchiolitis was assessed according to the clinical respiratory score (CRS) of Liu et al. (5). The patients with CRS ≥5 were included.
Peripheral oxyhemoglobin saturation is < 92%.

Exclusion criteria

Children admitted to the ICU for urgent invasive mechanical ventilation;
those who received standard oxygen therapy (SOT) or HFNCOT at other facilities before arrival;
those with an underlying medical condition (such as congenital heart disease, chronic lung disease, neuromuscular disease, metabolic disease, or immunocompromised);
those who had a craniofacial malformation, an upper airway obstruction, pneumothorax, or nasal trauma, and missing parental consent or a refused permission of the participant.
