Details and patient eligibility

About

The aim of this investigation is to compare the performance of two quantitative monitors utilized on post-anesthesia recovering patients. The ToFscan (Draeger Medical Inc., Telford, PA) represents one of the few standalone acceleromyography (AMG)-based quantitative monitors available for routine clinical use in the United States. The TetraGraph (Senzime AB, Uppsala, Sweden) is a standalone electromyography (EMG)-based quantitative monitor that recently received Conformité Européene (CE) approval. While both of these quantitative monitors can be utilized to guide intraoperative NMBA re-dosing and confirm recovery, they provide their objective data via drastically different techniques.
