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.

Condition Intervention Phase
Respiratory Distress
Drug: Inhalation of salbutamol diluted in hypertonic saline
Drug: Inhalation of salbutamol diluted in normal saline
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
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.

Primary Outcome Measures:
  • Change in the respiratory distress score (Tal) between the basal score and the final score after 3 salbutamol nebulizations [ Time Frame: 1 hour ]

Secondary Outcome Measures:
  • 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 ]

Estimated Enrollment: 74
Study Start Date: June 2008
Estimated Study Completion Date: October 2008
Estimated Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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

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.
