Laser therapy has become a mainstream part of chronic scar management in burns services across Australia. Laser allows for treatment of hypertrophic and contracted scars with a minimally invasive procedure, and has been shown to improve function. Many adult burns services are performing this in the outpatient setting under topical local anaesthetic, allowing for a shorter time to treatment at a lower resource cost. As the health system is increasing stretched for resources, being able to safely and comfortably perform burns laser in the outpatient setting is key to getting a greater number of patients to the end of their treatment. A necessary component of outpatient burns laser is adequate anaesthesia such that the procedure is tolerated and patients are comfortable. A polling of East Coast Australian Burns Services by one of our authors suggests that each unit use a different product of topical local anaesthetic. Some use off-the-shelf EMLA, while others compound their own mixture at a significantly increase cost, but are any products superior? This has drawn attention from other authors who completed a simulated laser scenario on normal skin in the assessment of 4 commercially available topical local anaeshetics, and found a significant difference between the products. However, no existing literature has assessed the efficacy of different topical local anaesthetics specifically in burns laser. Unlike normal skin, burns scar has different histology and biomechanics. We present our rationale and protocol for an RCT investigation of the superior topical anaesthesia in the hopes of improving patient comfort and minimising necessity of elective theatre time.
