The investigators plan the following specific aims:
Primary Objective: To examine if in children with acute asthma remaining in moderate to severe respiratory distress despite maximized initial bronchodilator and steroid therapy there is a reduction in hospitalization rate from the ED in those who receive nebulized Mg with salbutamol versus those receiving salbutamol only.
Hypothesis: The investigators hypothesize that the children with Pediatric Respiratory Assessment Measure (PRAM) ≥ 5 points after optimized initial inhaled bronchodilator and oral steroid therapies who are given nebulized Mg in addition to nebulized salbutamol will have significantly lower hospitalization rate within 24 hours of starting the study compared to those given salbutamol only.
- To compare a difference in the changes in the validated Pediatric Respiratory Assessment Measure (PRAM), respiratory rate, oxygen saturation and blood pressure from randomization baseline to 240 minutes in the two groups
- To determine if there is a significant association between the difference in the primary outcome between the groups and the patient's age, gender, baseline PRAM score, personal history of atopy and "viral-induced wheeze" phenotype.
Hypothesis(es) to be Tested In this randomized, double-blind seven-centre trial, the investigators hypothesize that children with acute asthma with a Pediatric Respiratory Assessment Measure (PRAM) of ≥ 5 points after optimized initial inhaled bronchodilator and oral steroid therapies who are given nebulized Mg in addition to nebulized salbutamol will have at least a 10% lower hospitalization rate within 24 hours of starting the study as compared to those given salbutamol only.

Other Name: Sodium Chloride for Injection USP Omega Laboratories Ltd.
- Hospitalization of Subject [ Time Frame: Up to 24 hours after treatment ]Defined as admission to an inpatient unit within 24hours of the start of experimental therapy due to continued/worsening distress.
- Pediatric Respiratory Assessment Measure (PRAM) [ Time Frame: 0, 20, 40 60, 120, 180, 240 minutes post dose ]PRAM is a validated measure of asthma severity in the Emergency Department
- Changes in Vitals [ Time Frame: 0, 20, 40, 60, 120, 180, 240 minutes post dose ]Respiratory Rate, O2 saturation, Blood pressure
- Number of Salbutamol Treatments [ Time Frame: Up to 240 minutes post dose ]This measure of additional therapy may strengthen the measure of benefit of inhaled magnesium
- Medical History and Phenotype [ Time Frame: Baseline ]The investigators will measure hospitalization and age, gender, pre-randomization PRAM score, personal history of atopy, and "acute viral induced wheeze" phenotype. This phenotype will be defined by age less than 5 years, co-existent upper respiratory tract infection, no interval symptoms between exacerbations, no atopy
