A neurological complication following interscalene brachial plexus block
Anaesthesia
|April 1, 1980
Summary
Permanent neurological damage occurred in nerve roots controlling arm movement after an interscalene brachial plexus block. This highlights potential risks associated with this regional anesthesia technique.
Area of Science:
- Neurology
- Anesthesiology
- Surgical Procedures
Background:
- The interscalene approach is a common regional anesthesia technique for brachial plexus block.
- Brachial plexus blocks aim to provide anesthesia and analgesia to the upper extremity.
- Potential complications, though rare, must be understood for safe practice.
Observation:
- A case report details a patient who developed permanent neurological deficits.
- The deficits affected the motor outflow of at least two nerve roots (C7, C8, T1).
- This occurred subsequent to an attempted interscalene brachial plexus block.
Findings:
- Permanent neurological damage to specific brachial plexus nerve roots (C7, C8, T1) was observed.
- The damage impacted the motor outflow, leading to functional deficits.
- Causality is suggested between the interscalene block and the neurological injury.
Implications:
- This case underscores the critical need for meticulous technique during interscalene brachial plexus blocks.
- Awareness of potential permanent nerve injury is crucial for anesthesiologists and surgeons.
- Further research into risk mitigation strategies for brachial plexus anesthesia may be warranted.
