Title: Nebulized 5% Hypertonic Saline for Infirmary Treatment of Acute Infant Bronchiolitis: A Randomized Trial
Brief Summary: The investigators reasoned that a hypertonic saline concentration higher than 3% could be safe and more efficacious in the treatment of bronchiolitis, alleviating severe symptoms and preventing the need for hospitalization in some instances.


Options:
A: Inclusion Criteria:

* Patients 0-12 months of age admitted to the hospital with a diagnosis of bronchiolitis.

Exclusion Criteria:

* status asthmaticus
* chronic cardiopulmonary disease
* Trisomy 21
* immunodeficiency or transplant recipient
* neuromuscular disease
* admission directly to the intensive care unit
* previous use of nebulized hypertonic saline less than 12 hours prior to presentation
* previous enrollment in the study in the 72 hours prior to presentation
B: Inclusion Criteria:

* Children aged 6 months or less
* Moderate (Respiratory Distress Assessment Instrument score of 4 or greater) viral bronchiolitis (as defined by McConnockie)
* Meeting Admission criteria

Exclusion Criteria:

* History of prematurity
* Chronic lung disease
* Cystic fibrosis
* Congenital heart disease
* Neuromuscular disease
* Airway anomalies
* Immunodeficiency
* Those requiring immediate intubation and ventilation.
C: Inclusion Criteria:

* Previously healthy infants under 1 year of age
* Admitted to hospital with a clinical diagnosis of acute bronchiolitis, following the UK definition of an infant with an apparent viral respiratory tract infection associated with airways obstruction manifest by hyperinflation, tachypnoea and subcostal recession with widespread crepitations on auscultation
* Requiring supplemental oxygen therapy on admission

Exclusion Criteria:

* Wheezy bronchitis or asthma - children with an apparent viral respiratory infection and wheeze with no or occasional crepitations
* Previous lower respiratory tract infections
* Risk factors for severe disease \[gestation \<32 weeks, immunodeficiency, neurological and cardiac conditions, chronic lung disease\]
* Subjects where the carer's English is not fluent and translational services are not available
* Requiring admission to high dependency or intensive care units at the time of recruitment
D: Inclusion Criteria:

* Infants aged ≤ 18 months presenting to the unit for the treatment of moderate-severe viral bronchiolitis were eligible for the study.
* Moderate-severe bronchiolitis required having a prodromal history consistent with viral upper respiratory tract infection followed by wheezing and/or crackles on auscultation and a Wang bronchiolitis severity score of ≥ 4 on presentation.

Exclusion Criteria:

Patients were excluded from the study if they had one or more of the following characteristics:

* Born preterm ≤ 34 weeks gestation,
* Previous history of wheezing,
* Steroid use within 48 hours of presentation,
* Obtundation and progressive respiratory failure requiring ICU admission,
* History of apnea with in 24 hours before presentation,
* Oxygen saturation ≤ 85% on room air at the time of recruitment,
* History of a diagnosis of chronic lung disease,
* Congenital heart disease, or
* Immunodeficiency.
