[Local complications after axillary block anesthesia]
Abstract:
The authors treated a local complication after axillary block, probably after intraneural injection of lidocaine. At the operation severe epineural fibrosis was found and released. The result was good after some months. After this the authors realized a study with 14 hand surgeons, and only few cases like the first case were found. This technique axillary block, is very reliable technique, but very few local complications can occur, and it's necessary to know them. It's possible to avoid this local problem with a serious technique to realize axillary block. Never intraneural injection and never many punctures to research paresthesia from the nerves of the brachial plexus.
Insights
Axillary block is a reliable procedure, but intraneural injection can cause epineural fibrosis. Careful technique, avoiding intraneural injection and multiple punctures, prevents this rare complication.
Area of Science:
- Anesthesiology
- Surgical Complications
Background:
- Axillary block is a common regional anesthesia technique for hand and upper extremity surgery.
- Potential complications, though rare, necessitate thorough understanding and prevention strategies.
Observation:
- A case of severe epineural fibrosis treated post-axillary block, likely due to intraneural lidocaine injection.
- Surgical release of the fibrosis resulted in a good long-term outcome.
Findings:
- A subsequent study involving 14 hand surgeons identified very few similar cases, confirming the rarity of this complication.
- The study reinforced the high reliability of the axillary block technique when performed correctly.
Implications:
- Knowledge of potential local complications, such as epineural fibrosis, is crucial for practitioners.
- Strict adherence to proper axillary block technique, specifically avoiding intraneural injections and excessive nerve stimulation, is essential for patient safety.
