Interventional
Description of intervention(s) / exposure
Following institutional ethical approval, 20 participants will be sourced, written consent will be obtained and they will be randomly divided into two groups (10 patients in each) with a control and interventional group. Group one (I) will receive standard opioid administration as per their treating team for pain associated with change of dressing to burn sites on the upper limbs . Group two (II) will receive will receive standard opioid intervention with the addition of an ultrasound guided single-shot axillary brachial plexus block (ABPB) using 0.375% ropivacaine of 20-30mls. All patients will be charted post-procedural pain relief and antiemetics as per their treating team, and the addition of regional blockade will not affect availability of pain relief in any way.
The interventional group will receive their ABPB in the designated anaesthetic block room prior to their dressing change. Blocks will be placed by qualified and experienced anaesthetic fellows and consultants under direct ultrasound guidance, employing aseptic technique, and according to standard practice.

The axillary brachial plexus block provides reliable analgesia to the upper limb, forearm and hand. Patients will be connected to observational monitoring including non-invasive blood pressure, electrocardiogram and pulse oximetry, in addition to oxygen delivery. Each patient will require intravenous access, and prior to the block performance, patients will receive pre-medication as needed. The pre-medication is given as a relaxant, not to induce full sedation. The block will be administered as follows:

• The patient is positioned in a recumbent position of about 45 degrees. The patients shoulder is abducted and arm extended to reveal the axilla. The probe is placed transverse to the axillary artery to obtain sufficient view of the axillary artery, axillary veins and 4 nerves of the plexus (radial nerve, ulnar nerve, median nerve and musculocutaneous nerve).
• The 50mm 22g short bevel block needle is inserted in the lateral aspect of the upper arm and using an in-plane ultrasound guided approach to ensure infiltration of local anaesthetic around each nerve.
The efficacy of the block will then be judged based on the three point sensory and function motor scale. Skin sensation will be assessed, along with functional capacity. This will determine if the block is adequate or requires additional administration of local anaesthetic.

Outcomes
Primary outcome [1] 302766 0
The efficacy of regional anaesthesia for the treatment of pain associated with dressing change in patients suffering burn related injuries will be judged based on the 10 point numeric pain scale.
Timepoint [1] 302766 0
Primary time point will include data collection during the immediate dressing change phase- patient pain will be recorded immediately before, during and after the dressing change procedure. Then daily for 7 days post dressing change or until discharge if that occurs sooner.
Primary outcome [2] 302767 0
The efficacy of regional anaesthesia will be judged based on rescue analgesia and opioid equivalents. This data will be collected prospectively and through review of medical records.
Timepoint [2] 302767 0
Primary time point will include data collection covering the 24 hours before dressing change procedure, requirements during the procedure, and then daily requirements for 7 days post dressing change or until discharge if that occurs sooner.
Secondary outcome [1] 336948 0
The efficacy of regional anaesthesia will be judged pre-operatively by a three point sensory and function motor scale. This scale is routinely utilised in regional anaesthesia assessment and has been employed across a variety of regional anaesthesia studies. It is a known method of assessment, though not a validated tool.
Timepoint [1] 336948 0
Assessment will take place 10 minutes, 20 minutes, and 30 minutes after the regional block has been placed and before the participants commence their dressing change procedure.
Secondary outcome [2] 348806 0
Patient functionality in terms of pain, self-efficacy and experience will be evaluated.
Timepoint [2] 348806 0
6 months post-procedure, patients will be followed up in the community setting via administration of 2 questionnaires (The Modified Brief Pain Inventory short form and EQ-5D-5L) and one semi-structured phone interview.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed envelopes. Participating clinicians are given randomly generated treatment allocations within sealed opaque envelopes. Once a patient has consented to enter the trial an envelope is opened and the patient is then offered the allocated treatment regimen.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomization, non-stratified, conducted through the use of Excel randomization and performed by an independent third party.

Summary
Brief summary
REPAIR is a study investigating the role of regional anaesthesia (RA) for reducing pain experienced during dressing change for patients who require split skin grafting after suffering burn injuries to the upper limbs.

There are approximately 50,000 burn related hospital admissions per annum in Australia at an economic cost of $230m. This patient cohort may experience neuropathic or nerve pain that is notoriously difficult to treat. This trial will compare current pain practice with the use of RA in patients who have suffered burns and require dressing changes on the ward post split-skin grafting procedures. This study aims to redefine the way clinicians treat burn pain, and to lay the ground work for further investigation into RA and optimization of care for patients with burn injuries.

Aim:
To assess the effectiveness of regional anaesthesia as an intervention for burn pain associated with change of dressings and removal of staples after split skin grafting procedures to the upper limbs.

Objectives:
1. To compare and contrast the outcomes of two patient cohorts receiving removal of staples and dressing change after upper limb split skin grafting including:
a. Control group receiving standard opioid intervention as per treating team.
b. Cohort receiving a single dose nerve block to upper limb grafting site.

Methods
Prospective, randomised clinical trial.

Following institutional ethical approval, 20 participants will be sourced from the Royal Brisbane and Women’s Hospital acute in-patient burns unit. Written, informed consent will be obtained before patients are enrolled in the study. Patients will only be enrolled if they meet the inclusion criteria, and consent to the study. This study population of 20 patients will be divided into two groups (10 patients in each) with a control and interventional group.

Once informed consent is obtained, participants will be randomised into two groups using a random number generator and sealed envelopes.Group one (I) will receive standard opioid intervention as per their treating team. Group two (II) will receive will receive standard opioid intervention with the addition of an ultrasound guided single-shot axillary brachial plexus block using 0.375% ropivacaine of 20-30mls. All patients will be charted post-procedural pain relief and antiemetics as per their treating team, and the addition of regional blockade will not affect availability of pain relief in any way.

All blocks will take place in the designated anaesthetic block room prior to dressing change procedure. Blocks will be placed by qualified and experienced anaesthetic fellows and consultants under direct ultrasound guidance, employing aseptic technique, and according to standard practice.The efficacy of the block will then be judged based on the three point sensory and function motor scale. Skin sensation will be assessed, along with functional capacity.

Patients will be followed up by a study member and data will be collected pertaining to numeric pain scores and opioid requirements daily for 7 days post-procedure or until discharge from hospital if it occurs sooner.
