Randomized Controlled Trial Comparative StudyUltrasound guided injection inside the common sheath of the sciatic nerve at division level has a higher success rate than an injection outside the sheath.
The recommendations for the level of injection and ideal placement of the needle tip required for successful ultrasound-guided sciatic popliteal block vary among authors. A hypothesis was made that, when the local anesthetic is injected at the division of the sciatic nerve within the common connective tissue sheath, the block has a higher success rate than an injection outside the sheath. ⋯ Our study suggests that for successful sciatic popliteal block in less than 30min, local anesthetic should be injected within the sheath.
