Clinical Trial Summary

Bronchiolitis is an acute viral infection of the lower respiratory tract. It is most commonly caused by respiratory syncytial virus (RSV). Only supportive therapy, including suctioning nasal secretions, water-electrolyte balance maintenance, and oxygen supplementation when needed, is recommended. The inhalation of 3% hypertonic saline is not recommended in bronchiolitis management. However, a recently published meta-analysis revealed that the inhalation of hypertonic saline can reduce the risk of hospitalisation for outpatients with bronchiolitis, while resulting in a shorter length of hospital stay and reduced severity of respiratory distress for inpatients, although the evidence is of low certainty. The aim of the study is to assess the efficacy of nebulised hypertonic saline for the treatment of children hospitalised with bronchiolitis.

Primary	Length of hospital stay (LOS).		From admission to hospital discharge
Secondary	Number of participants requiring oxygen supplementation		During the intervention
Secondary	Duration of oxygen supplementation	among those requiring oxygen	During the intervention
Secondary	The time until the infant will be assessed as being 'fit for discharge'	which is defined as the point at which the infant will be feeding adequately (taking >75% of their usual intake based on parents' assessment) and will have a saturation of at least 92% for 6 h on room air, while the axillary body temperature will remain - among those requiring oxygen	During the intervention
Secondary	Number of participants requiring hospital readmission after discharge		7 days after the end of interventions
Secondary	Number of adverse events	especially incidence of acute otitis media and pneumonia	7 days after the end of interventions
Secondary	Worsening of clinical status, including the following:	PICU admission The need for oxygen supplementation via HNFC; Bronchospasm within 30 minutes of a nebulised study treatment as indicated by an increase/worsening of the RDAI of <4 points.	During the intervention
Secondary	Value of clinical severity score (RDAI and Wang Scale)	30 minutes after intervention and 24 h, 48 h, and 72 h after enrolment	During the intervention
