Summary

A novel lateral approach for sciatic nerve block allows patients to remain supine, simplifying anesthesia for lower limb surgery. This technique provides effective pain relief with a low complication rate.

Area of Science:

  • Anesthesiology
  • Regional Anesthesia
  • Surgical Procedures

Background:

  • Sciatic nerve block is crucial for lower extremity surgery.
  • Existing techniques often require patient repositioning, increasing complexity.
  • Novel landmarks for a high lateral approach can simplify sciatic nerve blockade.

Purpose of the Study:

  • To describe a novel, high lateral approach for sciatic nerve block.
  • To assess the feasibility of performing the block in the supine position.
  • To evaluate the efficacy and safety of this technique for foot and ankle surgery.

Main Methods:

  • Prospective study of 107 patients (ASA I-III) undergoing foot/ankle surgery.
  • Sciatic nerve block performed in the supine position using a high lateral approach and nerve stimulation.

  • Anesthetic solution injected after negative test dose; sensory and motor blockade assessed post-procedure.

    • Main Results:

    • High success rate for sciatic nerve block (tibial and superficial peroneal nerves always blocked).
    • Effective sensory blockade in L5 (100%) and S1 (98%) dermatomes.
    • Low incidence of complications, with no major incidents reported.

    Conclusions:

    • The lateral technique enables sciatic nerve block and catheter insertion with the patient supine.
    • This approach offers a high rate of effective anesthesia.
    • The technique is associated with a low incidence of side effects, improving patient comfort and procedural ease.
