Adult patients with burns admitted to the burns service at St. Andrews with <7% burns and undergoing split skin grafts where the donor site will be the anterolateral thigh only and expected to be at least 0.5% total body surface area (TBSA).
1. Patients <16 years old
2. Patients unable to comment on the pain scores effectively e.g., unable to speak English
3. Patients unable to give informed consent e.g., dementia
4. Patients refusing consent for the fascia iliaca block
5. Patients requesting a particular form of analgesia
6. Patients previously on treatment for chronic pain conditions
7. Patients from whom multiple donor sites are anticipated
8. Patients with renal impairment sufficient to alter the planned opiate dosage
9. Patients with a current or previous history of opiate abuse

- Primary Outcome Measures
Name Time Method The use of opiate painkillers at 24 and 48 hours. Our chosen threshold for a clinically significant difference will be a 20% difference in opiate usage at 24 and 48 hours between patients receiving fascia iliaca blocks, compared to those receiving the same volume and concentration of local anaesthetic via direct infiltration into the skin.
- Secondary Outcome Measures
Name Time Method 1. Maximum pain score 6 hours after surgery, first post-operative day and second post-operative day<br>2. Time to first dose of opiate medication after discharge from recovery<br>3. Patient satisfaction with post-operative analgesia, assessed at 24 and 48 hours<br>4. The density and duration of muscle weakness associated with fascia iliaca blocks by the use of bromage scores in the first and second post-operative day (does not include patients who are not allowed to move the grafted leg)
