What is an Intraneural injection?

Intraneural injection was defined as nerve area (NA) increase of ≥15% and one or more additional ultrasonographic markers (nerve swelling, proximal–distal diffusion within epineural tissue).

What are the complications of peripheral nerve block?

Serious complications of peripheral nerve blocks include nerve injury, catheter infection, bleeding, and LAST. Intraneural injection occurs frequently with nerve stimulator or ultrasound-guided techniques. It is rarely associated with nerve injury. Lipid emulsion therapy is effective in treating severe LAST.
