Clinical Trial Summary

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

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.

Intervention

Procedure:
• Interscalene Nerve Block
Patients undergoing shoulder surgery will be given an Interscalene Nerve Block. The patients' strength and sensation in their hand and forearm will be tested to determine if the nerve block is affectively delivering anesthetic to the nerves that serve these areas.
