Train-of-four Monitoring Using the Tetragraph

Train-of-four Monitoring Using the Tetragraph Neuromuscular Transmission Monitor and Comparison to Standard (Visual) Train-of-four Assessment With a Peripheral Nerve Stimulator

This is a prospective study that will evaluate the feasibility of using the Tetragraph Neuromuscular Transmission Monitor in comparison to standard (visual) train-of-four assessment with a peripheral nerve stimulator in pediatric patients undergoing surgery.

Inclusion Criteria:

• Pediatric patients requiring anesthetic care and use of neuromuscular blockade
• Weight range of 20 - 60 kg

Exclusion Criteria:

• Patients with history of a peripheral neurologic or neuropathic disorder
• Patients in whom the upper extremity cannot be used for TOF monitoring
• Patients undergoing a surgical procedure in which neuromuscular blockade is not required
• Edematous patients
