Summary
This report describes a successful application of ultrasound-guided lumbar plexus block (LPB) in combination with a sciatic nerve block for emergency lower limb surgery.
Traditionally, LPB is performed using surface anatomical landmarks, and the injection site is confirmed by observing quadriceps muscle contraction to peripheral nerve stimulation.
The authors discuss the anatomy, sonographic features, and the technique of identifying the lumbar plexus, highlighting the potential benefits of using ultrasound guidance in this approach.
