Anatomic Variation of Subclavian Artery Visualized on Ultrasound-Guided Supraclavicular Brachial Plexus Block

Use of ultrasonography for performance of nerve and plexus blocks has made the process simpler and safer. However, at times, variant anatomy of the visualized structures can lead to failure of blocks or complications such as intravascular injections. This is especially true in case of novice operators. We report a case of a variant branch of subclavian artery, possibly the dorsal scapular arter...

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.

Ultrasound-guided supraclavicular brachial plexus block.

UNLABELLED In this study, we evaluated state-of-the-art ultrasound technology for supraclavicular brachial plexus blocks in 40 outpatients. Ultrasound imaging was used to identify the brachial plexus before the block, guide the block needle to reach target nerves, and visualize the pattern of local anesthetic spread. Needle position was further confirmed by nerve stimulation before injection. T...

Ultrasound-Guided Subclavian Vein Cannulation in Neonate via Supraclavicular Approach

Central venous cannulation of infants may be challenging. Ultrasonography is recommended and has been found superior to classic landmark technique in pediatric central venous cannulation. The cannulation of the subclavian vein using supraclavicular approach under real-time ultrasound guidance is a novel technique. It may have advantages over ultrasound-guided jugular vein cannulation in specifi...

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 ...
