Official title
Ultrasound Visualization v. Electrical Nerve Stimulation for the Safety and Effectiveness of Interscalene/Axillary Nerve Block in Upper Extremity Surgery: A Randomized Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Hypothesis and Specific Aims: The investigators hypothesize that ultrasound (US) visualization is as effective as nerve stimulation (NS) for identification of peripheral nervous structures and may be associated with less trauma and patient discomfort. Specifically, the investigators believe that equivalent rates of surgical anesthesia are achievable with non-invasive ultrasonic needle guidance in comparison to needle guidance by intensity of motor fiber response to intermittent electrical nerve stimulation. Specifically, the number of needle sticks to identify the brachial plexus and total time to plexus sheath injection may be reduced while achieving similar efficacy rates. The investigators hypothesize that similar composite safety and efficacy endpoints but improved patient satisfaction and acceptance will favor US over NS guidance of nerve blocks indicated for surgery on the extremity surgery. However, the investigators believe that an economic assessment based upon capital hardware investment, operating room utilization, total block time, and pay for performance patient satisfaction metrics require examination prior to assimilation of new technology into clinical practice.
