Brief Summary:
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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Consistency in values obtained by ToFscan and TetraGraph [ Time Frame: up to 10 hours postoperatively ]
    Obtain ToFscan values and TetraGraph values simultaneously in the recovery period simultaneously (same measuring units).


Secondary Outcome Measures :
  1. Number of patients with incomplete neuromuscular blockade reversal [ Time Frame: up to 10 hours postoperatively ]
    Identify patients who demonstrate TOF reading below 90% in the recovery period

  2. Patient's reported discomfort with use of devices [ Time Frame: up to 10 hours postoperatively ]
    Number of patients reporting discomfort associated with use of either device
