Therapeutic nerve blocks for chronic pain.

J N Ghia, G S Duncan, D S Scott

    American Family Physician
    |July 1, 1979
    PubMed
    Summary

    Therapeutic nerve blocks effectively treat acute pain but are less effective for chronic pain. Careful patient screening for organic disease and psychological factors is crucial for successful nerve block therapy.

    Area of Science:

    • Pain Management
    • Neurology
    • Anesthesiology

    Background:

    • Nerve blocks are a common treatment for acute pain.
    • Their efficacy in chronic pain management is limited.
    • Patient selection is critical for therapeutic nerve blocks.

    Purpose of the Study:

    • To define the criteria for selecting patients for therapeutic nerve blocks.
    • To differentiate between effective and ineffective candidates for nerve block procedures.

    Main Methods:

    • Screening candidates for nerve blocks involves assessing organic disease.
    • Psychological and behavioral disorders are evaluated.
    • Differential nerve blocks are used to identify pain mechanisms.

    Main Results:

    • Effective candidates typically have identifiable organic disease.
    • Minimal psychological or behavioral issues are associated with better outcomes.
    • Evidence of sympathetic or somatic pain mechanisms predicts success.

    Conclusions:

    • Careful patient selection significantly impacts the success of therapeutic nerve blocks.
    • Screening should include medical, psychological, and pain mechanism assessments.
    • Nerve blocks are best suited for patients with specific organic conditions and pain types.
