Regional anesthesia in pain management

Area of Science:

• Anesthesiology
• Pain Medicine
• Neurology

Background:

• Recent systematic reviews and guidelines highlight the importance of local anesthetic neural blocks.
• Focus on applications in both postoperative and chronic pain management.

Purpose of the Study:

• To review current evidence on neural blocks with local anesthetics for postoperative and chronic pain.
• To identify areas with strong evidence and areas requiring further research.

Main Methods:

• Review of recent systematic reviews and guidelines.
• Analysis of evidence supporting diagnostic and therapeutic nerve blocks.
• Evaluation of ultrasound guidance in regional anesthesia.

Main Results:

• Postoperative pain: Evidence supports surgical site infusions, continuous peripheral nerve blocks, and neuraxial analgesia for major procedures.
• Ultrasound guidance improves block performance but not nerve damage incidence.
• Chronic pain: Strong evidence for facet joint pain diagnosis; effective therapeutic blocks for headache (e.g., greater occipital nerve, sphenopalatine ganglion).
• Further research is needed for other chronic pain indications.

Conclusions:

• Regional anesthesia, including peripheral nerve and surgical site infusions, is strongly supported for postoperative pain.
• Local anesthetic blocks are valuable for diagnosing facet joint pain and treating headache.
• Further investigation is crucial for diagnostic and therapeutic nerve blocks in chronic pain management.
