Plain English Summary
Background and study aims
Acute bronchiolitis is a common medical condition which affects children. It is caused by any of the common cold viruses, which cause the airways to become blocked, leading to difficulty breathing. The worst-affected babies require oxygen and help with feeding until they clear the virus themselves. Many treatments have been tried, but in all cases they were shown to be ineffective when properly tested. Saline is a common ingredient in nasal sprays, used to clear the airways of adults suffering with a cold. It has been suggested that inhaling a mist of 3% hypertonic saline (salt water) from a nebuliser (machine which converts liquid medication into a mist inhaled into the lungs) could be an effective way of treating acute bronchiolitis, and ensuring a quick recovery. The aim of this study is to find out whether nebulising infants suffering from acute bronchiolitis with 3% hypertonic saline can reduce the length of time that babies spend in hospital than standard supportive care.
Who can participate?
Infants under 1 year of age admitted to hospital with acute bronchiolitis who need oxygen therapy.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are nebulised with 3% hypertonic saline solution every 6 hours, as well as receiving standard supportive care and oxygen if required. Those in the second group receive standard supportive care and oxygen if required only. The time between admission and discharge from hospital is recorded for all participants. Participants in both groups are also followed up for 28 days, to monitor for any negative reactions (adverse events).
What are the possible benefits and risks of participating?
Not provided at time of registration.

Scientific title
Hypertonic Saline in Acute Bronchiolitis: a Randomised controlled trial and Economic evaluation
Acronym
SABRE
Study hypothesis
Comparing addition of nebulised hypertonic saline to usual supportive care in cohort of infants admitted with acute bronchiolitis.
1. Primary hypothesis is that the addition of 3% hypertonic saline to usual care results in significant (25%) reduction in the duration of hospitalisation of infants admitted with acute bronchiolitis.
2. Secondary hypotheses are that the addition of nebulised 3% hypertonic saline to usual care is associated with
2.1. Improved quality of life outcomes for carers
2.2. Shorter length of stay
2.3. Improved quality of life for infants
2.4. Reduced healthcare utilisation in the month after discharge
2.5. Cost-effectiveness for the NHS
2.6. The effect is independent of the underlying virus

Condition
Acute bronchiolitis
Intervention
Nebulised 3% hypertonic saline will be administered 6 hourly in the intervention group, in addition to standard supportive care, until the infant meets the pre-set criteria for discharge. A single use jet nebuliser with facemask (PARI Sprint with infant facemask); driven by piped oxygen will be used to administer the hypertonic saline. The control arm will receive standard supportive care.
Total duration of follow-up will be 28 days from entry to study.

Primary outcome measure
Current primary outcome measures as of 27/10/2011:
1. Time to fit for discharge, which will be judged to be when the infant is feeding adequately (taking more than 75% of usual intake)
2. Has been in air with a saturation of at least 92% for 6 hours, to reflect clinical practice.
Previous primary outcome measures:
2. Has been in air with a saturation of 94% or greater for 12 hours
Secondary outcome measures
1. Actual time to discharge
2. Readmission within 28 days from randomisation
3. Health care utilisation, post-discharge and within 28 days from randomisation
4. Duration of respiratory symptoms post discharge and within 28 days from randomisation
5. Infant and parental quality of life using the Infant Toddler Quality of Life (ITQoL) questionnaire at 28 days following randomisation.
