1. How to Perform a Femoral Nerve block
Princess Alexandra Hospital Emergency Department

2. Preparation:
Patient consent
Ultrasound – linear probe
skin prep
20mL syringe
pencil point needle
local anaesthetic
gauze

3. Why pencil point?
Use a pencil point needle to better appreciate passing through fascial planes and to limit trauma to the nerve.

4. Identify Anatomy
Left leg

5. Identify Anatomy FA
Femoral Nerve FV

6. Use 20 mL of 1% lignocaine or 0.5% bupivacaine or combination
Use 20mL syringe filled with local anaesthetic connected to pencil point needle
Use 20 mL of 1% lignocaine or 0.5% bupivacaine or combination
For the purposes of femoral blocks in the ED, the nerve stimulator connector can be removed with scissors

7. Approach the field with the needle from the lateral edge of the probe longitudinally

8. This way, you can visualise your needle in the field throughout the procedure

9. Once you are in the nerve sheath, aspirate and slowly administer anaesthetic

10. Clearly document the procedure in
clinical notes

11. Remember in PAH ED you must complete your Procedural Ultrasound competency before you can perform Ultrasound-guided Femoral Nerve Block independently
