Summary

A minor electric shock caused progressive hand pain, swelling, and weakness in a patient. This condition, identified as reflex sympathetic dystrophy, was successfully treated with cervicothoracic sympathetic blocks.

Area of Science:

  • Neurology
  • Vascular Medicine
  • Occupational Health

Background:

  • Electric shock injuries can lead to complex neurological and vascular complications.
  • Reflex sympathetic dystrophy (RSD), now known as Complex Regional Pain Syndrome (CRPS), is a poorly understood condition.
  • Understanding the link between minor trauma and chronic pain conditions is crucial for effective treatment.

Observation:

  • A 37-year-old female experienced progressive paresthesias, rest pain, swelling, and weakness in her right hand after an electric shock.
  • Symptoms developed over two months, indicating a chronic and evolving condition.
  • Physical examination revealed significant functional impairment of the affected hand.

Findings:

  • Plethysmography confirmed arterial vasoconstriction in the affected right hand.

  • The clinical presentation and diagnostic findings were consistent with reflex sympathetic dystrophy.
  • The patient's symptoms responded positively to targeted treatment.

    • Implications:

    • This case highlights the potential for seemingly minor electric shocks to trigger significant peripheral vascular and neurological dysfunction.
    • Cervicothoracic sympathetic blocks can be an effective treatment modality for electric shock-induced reflex sympathetic dystrophy.
    • Further research into the pathophysiology of electric shock-related CRPS is warranted to improve patient outcomes.
