Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients will be approached by members of the trial team and if agreeable by the patient, will be consented for the trial.
Randomisation and allocation will be masked to the trial staff, medical team and the patient.
Randomisation and allocation will be carried out using block randomisation by pharmacy. Numbered syringes will be provided which the trial member will use, and inform pharmacy of the syringe number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Statistical methods / analysis
A proposed sample of 160 patients is estimated following a power calculation using previous trials as a guideline [Skorodin et al, 1995; Hughes et al, 2003; Gonzalez et al, 2006]. To detect an absolute difference in FEV1 of 0.30L with at least 80% power and an alpha error level of 5%, 80 participants were required in each treatment arm.

Summary
Brief summary
Magnesium is used successfully to treat asthma exacerbations. Although COPD and asthma share common pathophysiology and first line therapies in acute exacerbations, little is known about the role of magnesium in acute exacerbations of COPD.
We aim to investigate whether magnesium used in conjunction with standard treatments provides better bronchodilation when compared with placebo with standard treatments.
