Summary

We will study if small children who become ill with respiratory distress during the RSV epidemic are better relieved with salbutamol nebulizations diluted in hypertonic (3%), instead of normal (0. 9%) saline.

Clinical Details

Official title: Safety and Efficacy of Hypertonic Vrs. Normal Saline as Diluent of Salbutamol to Reduce Respiratory Distress in Outpatients With the Clinical Diagnosis of Bronchiolitis During the RSV Epidemic.

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Change in the respiratory distress score (Tal) between the basal score and the final score after 3 salbutamol nebulizations

Secondary outcome:

Change in the respiratory distress score (Tal) between the basal score and the first nebulization

Change in the respiratory distress score (Tal) between the basal score and the second nebulization

Change in pulse oxymetry reading between the basal score and after each of the three nebulizations

Change in cardiac frequency, irritability, general condition or anything else between the basal score and the first, second and third nebulization

Detailed description: 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.
