Radial plus musculocutaneous nerve stimulation for axillary block is inferior to triple nerve stimulation with 2% mepivacaine.

Study Objective: To compare the extent of sensory and motor block with two different nerve stimulation techniques in axillary blocks.

Design: Prospective, randomized, investigator-blinded study.

Setting: Ambulatory surgery unit of a university hospital.

What is the minimum effective volume of local anesthetic required for sciatic nerve blockade? A prospective, randomized comparison between a popliteal and a subgluteal approach.

For sciatic nerve blockade, no study has defined the optimal volume of local anesthetic required to block the nerve. The current, prospective, randomized investigation was designed to find a minimum volume of 1.5% mepivacaine required to block the sciatic nerve using the subgluteal and posterior popliteal approaches.
