Abstract
Dexamethasone is a potent long acting corticosteroid that has been used as an anti-inflammatory, antiemetic, in diagnostic tests and other uses. It has been shown to prolong peripheral nerve block and extend the duration of analgesia when added to local anaesthetics.
The application of the ultrasound in supraclavicular brachial plexus block is of great significance. It has decreased the incidence of complications (such as pneumothorax and intravascular injection) and so improved the patient safety. It also improved the success rate of the block by visualization of the brachial plexus and detecting anatomical variations.
