Brief Summary
The objective of this study is to show that the use of electrodialyzed seawater reduces the duration (in days) of symptoms in acute infant bronchiolitis compared with the use of saline solution in infants aged 1 month to less than one year. B-CLASS study is a multicenter, prospective, controlled, randomized, double label blind.

Outcome Measures
Primary Outcomes (1)
Duration of resolution of illness (ROI)
It is the time it takes for the child to return to baseline according to the person administering the care. ROI is defined by ordinal scale from 0 to 4 on which parents globally rate symptoms according to the following categories: (1) worsened, (2) same, (3) improved, (4) resolved. The duration of ROI is the time it takes to obtain a score of 4.
At day 1, day 2, day 3, day 4, day 5, day 6, day 7, day 8, day 9, day 10
Secondary Outcomes (14)
An again medical consultation
At day 1, day 2, day 3, day 4, day 5, day 6, day 7, day 8, day 9, day 10

Study Arms (2)
Physiomer
EXPERIMENTALIt is a sterile, isotonic seawater-based solution, with a concentration equivalent to 9 g/L sodium chloride. This solution is packaged in 5 mL single-dose units. It is a Class IIa medical device manufactured by Laboratoire de la mer, and is CE marked. Electrodialyzed seawater solution is administered via the nasal passage, in line with current recommendations. Dosage varies according to age, and the pressure exerted on the unit dose enables the product to be administered into the nostril.
Saline solution
ACTIVE COMPARATORIt is a sterile, isotonic seawater-based solution, with a concentration egal to 0,9 g/L sodium chloride. This solution is packaged in 5 mL single-dose units. It is a Class IIa medical device manufactured by GiLBERT, and is CE marked. The saline solution is administered via the nasal passage, in line with current recommendations. Dosage varies according to age, and the pressure exerted on the unit dose enables the product to be administered into the nostril.
Interventions
Infants randomized to the control group will be given a saline solution by their parents for up to 10 days. Dosage is adapted according to the child's age and discomfort: * Infant \< 6 months: half a dose to a single dose administered per nostril 8 times a day. * Infant \> 6 months: one single dose administered per nostril 6 times a day.
Infants randomized to the experimental group will be given an electrolyzed seawater solution by their parents for up to 10 days. Dosage is adapted according to the child's age and discomfort: * Infant \< 6 months: half a dose to a single dose administered per nostril 8 times a day. * Infant \> 6 months: one single dose administered per nostril 6 times a day.
