Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation slips will be stored in numbered opaque sealed envelopes and opened only in consented patients prior to surgery
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Sequence will be computer generated in blocks.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Patients will be blinded from what injection they receive. Only the anaesthetist who performed the procedure knows what the patient received, others including an observer will be blinded and responsible for monitoring patient’s progress and pain treatment requirements. The data analyst will also be blinded.
