Infraclavicular brachial plexus block for regional anaesthesia of the lower arm.

Relevance to nursing care The use of regional anaesthesia reduces not only postoperative pain but also the risks of postoperative nausea and vomiting, and postoperative drowsiness, which are commonly associated with general anaesthesia. There are several commonly used techniques of blocking the brachial plexus, but it is not clear which, if any, is the best. This updated systematic review compared the effects of blocking the brachial plexus by injecting local anaesthetic in the area below the collar bone (the ICB) with other techniques.
