简要总结
Techniques of regional anaesthesia provide advantages over general anaesthesia. Supraclavicular brachial plexus block is the single most effective block for entire upper extremity and provides anaesthesia of all portions of upper extremity. To overcome the brief duration of action of local anaesthetics and to prolong intraoperative anaesthesia and postoperative analgesia many opioids have been tried with local anaesthetics.Ropivacaine, a local anaesthetic having wider safety margin, with decreased potential for central nervous system toxicity and cardiotoxicity, improves relative sensory and motor block profiles. Buprenorphine a semisynthetic opioid with longer duration of action cost effective and possess lesser degree of side effects such as sedation and respiratory depression.
