Effects of Interscalene Brachial Plexus Nerve Blocks on the Hand and Forearm
Effects of Interscalene Brachial Plexus Nerve Blocks on the Hand and Forearm

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

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.

Non-Probability Sample

Study population will consist only of patients undergoing orthopedic shoulder surgery.

  • Shoulder Surgery
  • Interscalene Nerve Block
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.
Shoulder Surgery
Patients will be given an interscalene nerve block and then strength and sensation of the hand and forearm will be tested to determine if the block is helping to anesthetize these areas.
Intervention: Procedure: Interscalene Nerve Block
