Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computer generated random number
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Due to difficulties in blinding the intervention and control, this will be an open study. The emergency department staff member cannulating the patient will administer either the vapocoolant spray or subcutaneous lignocaine, under the direction of a study investigator.
