Summary
Hyperbaric oxygen therapy may improve peripheral nerve recovery after microsurgical repair. This treatment accelerated functional recovery and improved nerve regeneration in a rat model.
Area of Science:
- Neuroscience
- Regenerative Medicine
- Surgical Innovation
Background:
- Peripheral nerve injuries are common consequences of limb trauma.
- Microsurgery enhances recovery but has limitations.
- Investigating novel therapeutic strategies is crucial for improving outcomes.
Purpose of the Study:
- To evaluate the long-term effects of hyperbaric oxygenation (HBO) on peripheral nerve repair.
- To assess functional and histological recovery after sciatic nerve transection and microsurgical repair in rats.
Main Methods:
- Forty male Wistar rats underwent sciatic nerve transection and microsurgical repair.
- Rats were randomly assigned to HBO treatment or control groups.
- Nerve recovery was assessed via neurophysiologic studies, foot-ankle angle response, and histopathology at 7 and 14 weeks.
Main Results:
- HBO treatment showed significantly higher amplitude, axon count, and blood vessel density at 7 weeks.
- At 14 weeks, HBO groups exhibited no denervation and improved foot-ankle angle response.
- HBO demonstrated a positive impact on nerve regeneration and functional recovery.
Conclusions:
- Hyperbaric oxygenation can enhance and expedite functional recovery in peripheral nerves post-microsurgery.
- HBO shows promise as an adjunctive therapy for peripheral nerve injuries.
- Further research may elucidate optimal HBO protocols for clinical application.
