Interventional
Description of intervention(s) / exposure
The initial dressing application will be conducted under a general anaesthetic within 48 hours of the burn injury. All participants will undergo a non-excisional debridement and cleaning with QV Wash prior to dressing application.

ARM 1: one of the two standard initial dressings Acticoat® (Smith and Nephew, Hull, UK) with Mepitel® (Molnlycke, Goteborg, Sweden) or Mepilex Ag® (Molnlycke, Goteborg, Sweden) will be applied. The second dressing change will occur 3-5 days after this. Each dressing change will be as per the standard procedure with research assessments at each dressing change until the wound is 95% or more re-epithelialised or referred for a graft.

ARM 2: Once the wound bed is sufficiently prepared the surgeon will apply the autologous cell suspension using the RECELL® Autologous Cell Harvesting Device (AVITA Medical, California, USA) as per the manufacturer’s recommendations. A layer of Biobrane® (Smith & Nephew Medical Ltd, Hull, UK) will be laid over the top of the RECELL® and the edges will be secured with Hypafix® (BSN Medical GmBH, Hamburg, Germany). Over the top of the Biobrane® will be a layer of Jelonet® (Smith & Nephew Medical Ltd, Hull, UK) then Kerlix® (Covidien, Mansfield, Ma, USA), and crepe bandage; secured by Hypafix®. The Jelonet®, Kerlix®, Crepe and external Hypafix® will be changed every 3-5 days until the wound is 95% or more re-epithelialised or Biobrane® is completely detached from the neo-epithelium.

DONOR SITE: The donor site location will be selected in a proximity as close as possible to the burn wound. The preparation of the site will undergo antimicrobial washing and irrigation. Once sufficient preparation has been achieved a pneumatic dermatome (Zimmer Inc., Warsaw, IN, USA) will be used to harvest a skin donor at a thickness of 6/1000 of an inch. Any excess autologous skin cell suspension will be applied to the donor site and dressed with inert standard dressing as per surgeon preference.

ARM 3: Once the wound bed is sufficiently prepared the surgeon will apply a layer of Biobrane® over the burn, which will be secured with Hypafix®. Over the top of the Biobrane® will be a layer of Jelonet® then Kerlix®, Crepe bandage; secured by Hypafix®. The Jelonet®, Kerlix®, crepe bandage and external Hypafix® will be changed every 3-5 days until the wound is 95% or more re-epithelialised or Biobrane® is completely lifted. Most of dressing changes will be completed by our burns nursing staff and where required a surgeon will also assist with the dressing changes.

Outcomes
Primary outcome [1] 304394 0
Days to Re-epithelialisation
Days to Re-epithelialisation of burn will be assessed with the implentation of three methods:
1. Clinical judgement from the consultant;
2. 3D camera photographs and analysis on specialist computer software; and
3. Blinded review of the 3D photographs by a panel of burn specialists (consultants and nurses). The 3D images will be obtained using a static 3D LifeVizII System® (Quantificare S.A., Cedex, France) and analysed with the Dermapix® (Quantificare S.A., Cedex, France) software. A dynamic 3D image will be taken with the GPC 3D Woundcare ( GPC, Swansea, UK) system. The clinical judgement of the attending burns surgeon will be the main assessment modality.

Adverse Event/Discontinuation:
Minimal adverse events are expected from the proposed interventions. At the study centre, known potential adverse events (e.g. infection, haematoma, intensive care admissions) have a standardised management protocol. Adverse events related to the interventions will be monitored through review of patient medical records, by guardian and participant (where applicable) self-report and by the treating clinicians. All adverse events will be communicated to the clinical health service and Human Research Ethics Committee (HREC). Discontinuation or alteration of treatment will be at the discretion of the treating clinical team. An independent Safety Monitoring Group will also monitor all aspects of patient safety throughout the study on a regular basis. After a minimum of 30 participants have been recruited,an independent statistician (blinded to the treatment allocation) will complete an interim analysis.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Treating physicians/nursing staff of all children meeting the inclusion/exclusion criteria presenting to the Lady Cilento Children’s Hospital, Brisbane will determine eligibility for enrolment in the study. With the parent/caregivers permission an investigator aligned with the study will discuss the study with the parents/caregivers and seek informed consent within 48 hours of the burn injury occurring. Once informed consent is obtained, participants will be randomised to one of three treatment groups. Randomisation will be undertaken by use of a randomisation sequence embedded into the REDCap data collection application by a third party not aligned with the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer generated randomisation sequence will be verified by statistician before upload onto the REDCap software application.

Statistical methods / analysis
Data will be graphed and summary statistics calculated for all outcomes. Where appropriate, non-parametric tests will be used. A survival analysis will be utilised, with the time to re-epithelialisation as the main outcome and dressing group as the explanatory variable. All other dataset will be analysed using appropriate methods for longitudinal data such as mixed model’s regression analysis or Generalised Estimating Equations (GEE). A p value of 0.05 will be considered statistically significant. The sample size calculation, and methodology regarding randomisation of the cohort and statistical analysis was finalised in consultation with a biostatistician.

Summary
Brief summary
The RECELL® autologous cell harvesting device enables rapid autologous epidermal replacement. The paucity of data substantiating its implementation in acute paediatric burn injuries warrants further evaluation. This study aims to compare effectiveness of three commercially available burn wound management approaches used for burn injuries. Informed consent of parent/guardians of children meeting the inclusion criteria will be obtained the demographic data collected. Participants will be randomised to standard silver dressing or Biobrane® with RECELL® or Biobrane® only. These will be initially applied under a general anaesthetic in the operation theatre. Data acquisition will be from digital imaging, sonography, colorimetry and assessments of pain, itch, dressing application ease, treatment satisfaction, intervention fidelity, health- related quality of life, scar assessment and health resource utilisation will be recorded. Intervals for data collection will be at baseline, at all 3-5 day dressing changes until wound is 95% or more re-epithelialised and at outpatient follow up at 3, 6 and 12 months post injury.
