Ulnar nerve injury associated with anaesthesia
Canadian Anaesthetists' Society Journal
|May 1, 1975
Summary
Post-anesthetic ulnar nerve lesions occurred in 35 patients, more frequently in males. Severity was unrelated to anesthetic factors, but prompt follow-up is crucial for preventing prolonged disability.
Area of Science:
- Neurology
- Anesthesiology
- Surgical Complications
Background:
- Ulnar nerve lesions can occur post-anesthesia, leading to potential disability.
- Understanding the anatomical and physiological factors is key to addressing these neuropathies.
Purpose of the Study:
- To report on 35 patients with post-anesthetic ulnar nerve lesions.
- To summarize etiological factors and diagnostic methods for ulnar nerve compression neuropathy.
- To discuss preventive measures and follow-up protocols.
Main Methods:
- Retrospective review of 35 patient cases with ulnar nerve lesions post-anesthesia.
- Discussion of anatomical and physiological factors contributing to neuropathy.
- Review of electromyography (EMG) and nerve conduction studies (NCS) utility.
Main Results:
- 35 patients developed ulnar nerve lesions in the post-anesthetic period.
- Compression neuropathies were more prevalent in males.
- Lesion severity did not correlate with age, sex, operation type, anesthetic type, or duration.
Conclusions:
- Ulnar nerve lesions remain a risk following anesthesia.
- Prompt diagnosis and management, including EMG/NCS, are essential.
- Preventive strategies and adequate follow-up are critical to mitigate prolonged disability.
