[Minimum effective concentration of bupivacaine for axillary brachial plexus block guided by ultrasound].

Introduction: The use of ultrasound in regional anesthesia allows reducing the dose of local anesthetic used for peripheral nerve block. The present study was performed to determine the minimum effective concentration (MEC90) of bupivacaine for axillary brachial plexus block (ABPB).

Methods: Patients undergoing hand surgery were recruited.

Determination of the minimum effective volume of 0.5% bupivacaine for ultrasound-guided axillary brachial plexus block.

Background And Objective: The use of ultrasound for needle correct placement and local anesthetic spread monitoring helped to reduce the volume of local anesthetic required for peripheral nerve blocks. There are few studies of the minimum effective volume of local anesthetic for axillary brachial plexus block. The aim of this study was to determine the minimum effective volume (VE90) of 0.
