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)
Subjects will be recruited from the thyroid surgery waiting list at Peninsula Health, and will be screened through the pre admission clinic for suitability. Once enrolled and consented, computer generation of randomisation will occur, an independent person will prepare the study or placebo injection following instructions in a concealed envelope and will hand the syringe to the anaesthetist for injection
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generation, will allocate individuals, then an independent person will take the allocated allotted envelope and hand this to another independent person for preparation
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
