Median Versus Ulnar Nerve Quantitative Electromyography Neuromuscular Blockade Monitoring Comparison

Medications used to relax the muscles are used during surgery. The amount of muscle relaxation can monitored with devices that stimulate a specific nerve and evaluate the muscle response. The response to, and recovery from, medications that relax the muscles are best described for a nerve in the arm called the ulnar nerve. The investigators believe that other nerves in the arm, such as the median nerve, could be used to monitor the amount of muscle relaxation. The purpose of this study is to compare the muscle response at two different nerve sites after giving medications to relax the muscles. This study is going to measure the depth of muscle relaxation during surgery at two different sites. The muscle response to stimulation of the ulnar nerve (located in the arm) will be compared to the muscle response to stimulation of the median nerve (also located in the arm).
