Summary

Continuous lumbosacral plexus block using an epidural catheter technique provides effective unilateral lower limb anesthesia. This method is safe and recommended when other regional anesthesia techniques are contraindicated.

Area of Science:

  • Anesthesiology
  • Regional Anesthesia
  • Pain Management

Background:

  • Continuous regional anesthesia techniques are crucial for prolonged surgical procedures and postoperative pain management.
  • Traditional epidural and spinal anesthesia have limitations and contraindications, necessitating alternative approaches for lower limb surgeries.

Observation:

  • A novel technique involving continuous lumbosacral plexus block was performed using a catheter inserted via an epidural needle.
  • The catheter was placed between the quadratus lumborum and psoas muscles, targeting the lumbar and sacral plexuses.
  • Radiographic confirmation showed precise catheter proximity to the lumbosacral plexus.

Findings:

  • Successful unilateral lower limb surgical anesthesia was achieved in all reported cases.

  • Anesthesia onset ranged from 12 to 20 minutes following the injection of 40-70 mL of local anesthetic.
  • No adverse side effects were reported in the 15 cases (3 initial + 12 further).

    • Implications:

    • This continuous lumbosacral block technique offers a viable and safe alternative for unilateral lower limb anesthesia.
    • It is particularly beneficial in patients where spinal or epidural anesthesia is contraindicated.
    • The method demonstrates potential for improved patient outcomes and pain control in specific surgical scenarios.
