Summary
Vitamin B12 injections guided by ultrasound may restore function in brachial plexus injuries (BPI). This technique precisely targets nerves, potentially improving motor and sensory outcomes for patients with post-ganglionic BPI.
Area of Science:
- Neurology
- Regenerative Medicine
- Medical Imaging
Background:
- Brachial plexus injury (BPI) treatment is challenging, with limited options for restoring upper limb function.
- Vitamin B12 shows potential for nerve regeneration and pain management, relevant to BPI recovery.
Observation:
- A case study details ultrasound-guided perineural vitamin B12 injection for a 50-year-old man with BPI from a traffic accident.
- The injection precisely targeted the C6 root neuroma within the brachial plexus.
Findings:
- The patient experienced improved motor and sensory functions in the affected upper limb over six months post-injection.
- Ultrasound guidance ensured accurate delivery of vitamin B12 to the injured nerve site.
Implications:
- Ultrasound-guided perineural vitamin B12 injection presents a promising, personalized treatment for post-ganglionic BPI.
- This minimally invasive approach may benefit patients unresponsive to initial treatments within three months.

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
496
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
