This study aims to examine the effect of nebulized 3% hypertonic saline in the treatment of viral bronchiolitis. The investigators hypothesize that nebulized 3% saline will decrease rate of hospital admission, decrease clinical severity scores, and decrease length of stay.
Bronchiolitis is the most common viral respiratory infection in young children and infants. It is responsible for hundreds of thousands of outpatient visits and hospitalizations every year. Hypertonic saline may decrease swelling in the lung tissue, improve the patient's ability to clear secretions, and decrease nasal congestion. Hypertonic saline nebulizations have already been used effectively in patients with cystic fibrosis and in a few small trials on infants with bronchiolitis. Patients who come to the emergency department or inpatient ward of two urban free-standing pediatric hospitals in California between December and April and are diagnosed with bronchiolitis will be randomized into two groups- the control group will receive nebulized 0.9% normal saline, while the study group will receive nebulized 3% hypertonic saline. Nebulizations will be pretreated with albuterol, to prevent the theoretical risk of increased wheezing in patients with undiagnosed underlying asthma. Patients will be given up to 3 nebulizations in the emergency department, after which time the attending physician will decide whether admission to the hospital is required. Patients who are admitted will continue to receive the same nebulized treatment every 8 hours until discharged. Additional interventions such as epinephrine treatments and antibiotics can be ordered as indicated by the patient care team.
Investigators will measure symptom severity before and after treatments using the respiratory distress assessment instrument (RDAI). We will compare rates of being admitted to the hospital in each group. We will also compare RDAI scores, average length of stay, number of additional respiratory treatments needed, number of hours requiring oxygen, amount of IV fluid needed, and frequency of adverse effects. We hypothesize that nebulized hypertonic saline will be a safe, cost-effective, and efficacious therapy which can be utilized in the outpatient setting to prevent hospital admission, as well as decrease length of stay for patients who require admission. Given the significant disease burden of viral bronchiolitis, the potential impact is substantial.

We hypothesize that infants with bronchiolitis treated with nebulized epinephrine in the Emergency Department (ED) and a 2-day course of oral dexamethasone will have fewer hospitalizations...
The purpose of this study is to determine whether nebulized 3% hypertonic saline is more effective than the current standard of care in the treatment of viral bronchiolitis in children.
Bronchiolitis is a common disease of infancy and a main reason for infants' hospital admissions in the first 2 years of life. The main cause of bronchiolitis is RSV (respiratory syncytial ...
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 preve...

This study evaluated the cost-effectiveness of hypertonic saline (HS) inhalations for infant bronchiolitis, compared to normal saline inhalations or standard treatment without inhalations as controls.
Acute bronchiolitis is common in young children and some children develop chronic cough after their bronchiolitis. We thus undertook systematic reviews based on key questions (KQs) using the PICO form...

There are no medications known that improve the outcome of infants with bronchiolitis. Studies have shown the management of bronchiolitis to be varied.
Tests involving inhalation of allergens (nebulized or in dust form), nebulized pharmacologically active solutions (e.g., histamine, methacholine), or control solutions, followed by assessment of respiratory function. These tests are used in the diagnosis of asthma.
