Bronchiolitis Respiratory Distress | Drug: Inhalation of salbutamol diluted in hypertonic saline Drug: Inhalation of salbutamol diluted in normal saline | Phase 2 |
In Santiago, Chile, a near collapse of health services is a notorious feature of every winter when vast numbers of small children line for attention because of respiratory distress caused by a probable RSV infection.
Our study will examine if nebulized salbutamol diluted in hypertonic (3%), instead of normal (0.9%) saline, provides better relief in outpatients.
If hypertonic saline proves safe and effective, the patients could be better managed and the pressure for attention diminished at a low cost, by a simple change in the saline ampule.

---|---|
Experimental: 1
Salbutamol is diluted in hypertonic (3%) saline.
|
Drug: Inhalation of salbutamol diluted in hypertonic saline
The first of 3 nebulizations of 0.5 mg of Salbutamol is diluted in 3.5 ml of hypertonic (3%) saline. The second and the third are diluted in normal (0.9%) saline.
Other Name: Albuterol diluted in hypertonic saline |
Active Comparator: 2
Salbutamol is diluted in normal (0.9%) saline.
|
Drug: Inhalation of salbutamol diluted in normal saline
The 3 nebulizations of 0.5 mg of Salbutamol are diluted in 3.5 ml of normal (0.9%) saline.
Other Name: Albuterol diluted in normal saline |
- Change in the respiratory distress score (Tal) between the basal score and the final score after 3 salbutamol nebulizations [ Time Frame: 1 hour ]
- Change in the respiratory distress score (Tal) between the basal score and the first nebulization [ Time Frame: 15 to 20 minutes ]
- Change in the respiratory distress score (Tal) between the basal score and the second nebulization [ Time Frame: 15 to 20 minutes after the first nebulization ]
- Change in pulse oxymetry reading between the basal score and after each of the three nebulizations [ Time Frame: 1 hour ]
- Change in cardiac frequency, irritability, general condition or anything else between the basal score and the first, second and third nebulization [ Time Frame: 1 hour ]
