Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Preschool patients with wheeze will be identified at triage, by the asigned nurse or medical staff caring for the patient in the emergency department of our tertiary children's hospital.
A PRAM score will be taken prior to the administration of any salbutamol.
Patients will receive standard treatment with salbutamol for wheeze. This is 3 dose of 6 puffs via spacer every 20 minutes. If the PRAM score reduces by 2 points or more then patients will be invited to take part in the study.
If they agree then the treating nurse will select a sequential envelope from a closed box. The card inside has the study number written on it corresponding to a number on the medication bottle.
The study numbers have been randomised to treatment or placebo.
The study cards have been radomised to the envelopes.
The allocation of the study number and the cards to the envelopes are both random.
The nurse then calculates a dose in mls to be administered to the patient this is written on the bottle.
The bottles are identical.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation of study numbers to treatement or placebo was done using the random number generation feature in excel.

The allocation of study number cards to sequential envelopes was done using the random number generation feature in excel.
