Summary
A novel lateral approach for sciatic nerve block in the popliteal fossa is effective and safe. This technique is particularly beneficial for patients unable to assume a prone position.
Area of Science:
- Anesthesiology
- Surgical Anatomy
Context:
- Sciatic nerve blocks are crucial for lower limb surgeries.
- Traditional approaches may pose challenges for certain patient positions.
Purpose:
- To evaluate the efficacy and safety of a modified lateral approach for sciatic nerve block.
- To utilize unique anatomical landmarks for nerve localization.
Summary:
- A lateral approach using modified anatomical references (muscle groove intersection and femoral axis) was performed on 50 patients for foot surgery.
- The technique demonstrated high success rates (90% with one puncture), with a mean onset time of 28.3 minutes and no major complications.
- Puncture occurred proximal to the lateral femoral condyle, with depths ranging from 3.8 to 9 cm.
Impact:
- This approach offers a simpler, safer alternative for sciatic nerve blockade.
- It provides a valuable option for patients with positioning difficulties, enhancing surgical accessibility.
