Minimum effective volume of mepivacaine for ultrasound-guided supraclavicular block

Minimum effective volume of mepivacaine for ultrasound-guided supraclavicular block

BACKGROUND The aim of this study was to estimate the minimum effective volume (MEV) of 1.5% mepivacaine for ultrasound-guided supraclavicular block by placing the needle near the lower trunk of brachial plexus and multiple injections. METHODS Thirty patients undergoing forearm and hand surgery received ultrasound-guided supraclavicular block with 1.5% mepivacaine. The initial volume of local ...

Minimum effective volume of lidocaine for ultrasound-guided infraclavicular block.

BACKGROUND The aim of this study was to determine the minimum effective volume of lidocaine 1.5% with epinephrine 5 μg/mL in 90% of patients (MEV(90)) for single-injection ultrasound-guided infraclavicular block (ICB). METHODS Using an in-plane technique, a single-injection ultrasound-guided ICB was performed: a 17-gauge, 8-cm Tuohy needle was advanced until the tip was located dorsal to the ...

Ultrasound guided supraclavicular block.

Ultrasound guided regional anaesthesia is becoming increasingly popular. The supraclavicular block has been transformed by ultrasound guidance into a potentially safe superficial block. We reviewed the techniques of performing supraclavicular block with special focus on ultrasound guidance.

Myoclonus of ipsilateral upper extremity after ultrasound-guided supraclavicular brachial plexus block with mepivacaine

Estimation 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 0.5% bup...
