Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1 - Interscalene nerve block [brachial plexus block] (ISB), inserted under ultrasound-guidance by a consultant anaesthetist.
- Ropivacaine 100mg + Clonidine, 75mcg, made up to 20mL with 0.9% saline
- Single dose, prior to surgery.

Arm 2 - Suprascapular Nerve Block + Axillary Nerve Block (SSNB+ANB), inserted under ultrasound-guidance by a consultant anaesthetist.
- Ropivacaine 100mg + Clonidine, 75mcg, made up to 20mL with 0.9% saline
- Single dose, prior to surgery. 10mL per nerve.
- Adherence not applicable, blocks inserted after the patient is under GA
Arm 3 - Suprascapular Nerve Block + Axillary Nerve Block (SSNB+ANB), inserted by arthroscopic guidance by a consultant orthpaedic surgeon.
- Ropivacaine 100mg + Clonidine, 75mcg, made up to 20mL 0.9% saline
- Single dose, during surgery, 10mL per nerve
- Adherence not applicable, blocks inserted after the patient is under GA

Outcomes
Primary outcome [1] 303817 0
Efficacy of pain management in the perioperative period, as assessed by pain scores (obtained through use of visual analogue scale) and records of analgesic requirement/administration. [Composite means of determining primary outcome - efficacy of pain management - continuous outcome]
Timepoint [1] 303817 0
Immediate post-operative period (while participant is in Post-anaesthetic recovery unit). VAS score will be taken at two timepoints in PACU:
1. When participant is sufficiently awake to complete the score (initial pain score)
2. Upon discharge from first-stage PACU (generally 30-60min after arrival)
Secondary outcome [1] 340219 0
Patient satisfaction with their experience, assessed through use of a questionnaire.
The questionnaire is an adapted version of that used for evaluation of patient satisfaction with regional anaesthesia by Montenegro et al (2006). It has been translated from the original French and adapted to better suit the design of this project.
Timepoint [1] 340219 0
1 week post-operatively.

Statistical methods / analysis
Assuming Type I error (alpha) to 5% (p = 0.05) and Type II error (beta) to 0.2 (power equal to 80%), the sample size calculated to be able to observe differences in block efficacy was 35 participants per study group; a total of 105 study participants.
To compensate for 10% expected loss to follow-up, 40 participants will be recruited to each of the study groups; a total of 120 patients.

Summary
Brief summary
This study aims to compare the efficacy of three methods of regional anaesthesia in shoulder arthroscopy, as well as to compare patient satisfaction with the three methods. People undergoing shoulder arthroscopy will be invited to take part in the trial and will be randomised to one of three groups if they accept.
The three groups comprise an Interscalene block, inserted by an anaesthetist; a combined suprascapular & axillary nerve block inserted by an anaesthetist;and the combined block inserted by the treating surgeon during the procedure.
Outcomes examined by this study include pain levels after the operation (in the recovery room, the next day & out to a week later), how much pain relieving medication was used and how satisfied the participants were with their experience of regional anaesthesia (through use of a survey form).
The findings of this study will be utilised to guide clinical practice in the use of regional anaesthesia in arthroscopic shoulder procedures.
