Motor-sparing regional anaesthesia for lower limb burns: A novel combination of peripheral nerve blocks

• Burn pain is severe, dynamic, and often requires multimodal analgesia. • Opioid reliance risks chronic abuse and opioid-induced hyperalgesia. • Novel regional anaesthesia offers motor-sparing analgesia for complex burns. • Complete cutaneous analgesia of thigh is achieved using multiple regional techniques. • Future research should extend block duration and refine nerve mapping. Pain associated with burns injury is complex and can be challenging to manage. Regional anaesthesia is an emerging adjunct to the traditional multimodal approach. This case report outlines a novel motor sparing cutaneous regional anaesthesia technique for a 35-year-old male with 12.5% total body surface area lower limb burn. By blocking anterior femoral cutaneous nerve, lateral femoral cutaneous nerve, saphenous nerve and posterior femoral cutaneous nerve, we achieved effective postoperative analgesia while preserving motor function in a patient with significant risk factors for severe post operative pain. No additional systemic analgesia was required for the duration of the nerve block.
