Electromyographic and Acceleromyographic Monitoring in Restricted Arm Movement Surgical Setting

Electromyographic and Acceleromyographic Monitoring in Restricted Arm Movement Surgical Setting. A Prospective, Randomized Trial.

Researchers are comparing the ease of use and repeatability of the force vs electrical activity produced by a muscle after it has undergone nerve stimulation during a surgical procedure in which the patients' arm movement is restricted (placed under surgical drapes) in laparoscopic or robotic procedures.

Inclusion Criteria:

• Age > or = 18 years old
• Patients willing to participate and provide an informed consent
• Patients undergoing an elective laparoscopic or robotic surgical procedure that requires use of NMBA agents administered intraoperatively.

Exclusion Criteria:

• Patients with disorders, such as stroke, carpal tunnel syndrome, broken wrist with nerve damage, Dupuytren contracture, or any similar wrist injury.
• Patients with systemic neuromuscular diseases such as myasthenia gravis
• Patients with significant organ dysfunction that can significantly affect pharmacokinetics of neuromuscular blocking and reversal agents, i.e., severe renal impairment or end-stage liver disease.
• Patients having surgery that would involve prepping the arm or leg into the sterile field
