Background and Objectives. Sciatic nerve blocks are perceived as unreliable, technically demanding, and uncomfortable. With strict criteria to define success rates, we designed a study to examine the efficacy of two techniques of sciatic nerve block.

Methods. All blocks were performed by a novice in sedated patients using an insulated needle and a nerve stimulator.

Results. Overall success with both techniques was 87.5%. One transient neurologic deficit attributed to the sciatic nerve block was observed; otherwise, the technique provided satisfactory anesthesia without complications.

Conclusions. Patient acceptance was excellent.

  • Anesthetic techniques
  • regional
  • sciatic
  • local anesthetic
  • bupivacaine
  • equipment
  • nerve stimulator
  • complications
  • nerve damage.
