Study Overview

Brief Summary

Research study to determine the proportion of cases in which an interscalene brachial plexus nerve block produces hand and forearm anesthesia.

Detailed Description

This is a research study to prospectively determine the proportion of cases in which an interscalene brachial plexus nerve block produces hand and forearm anesthesia. The investigators will investigate this issue in patients having shoulder and not hand/forearm surgery. We will test hand grip strength and sensation to determine if the hand and forearm are responding to the anesthesia.

A comparison of post operative pain relief after surgery to the upper arm. An interscalene block involves an injection of local anaesthetic in the neck tothe nerves that supply the sensation to the arm. A stellate ganglion block involves ain injection of local anaesthetic in the neck to the sympathetic nerves to the arm.We propose that an interscalene brachial plexus block combined with stellate ganglion block will give superior postoperative analgesia compared to interscalene brachial plexus block alone in major orthopaedic surgery of the upper limb.MedDRA version: 14.0Level: LLTClassification code 10054711Term: Postoperative painSystem Organ Class: 10022117 - Injury, poisoning and procedural complications
