Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research is to determine the time it takes to reverse the effects of the intraoperative medication given to relax the muscles and how this period of recovery correlates with a function of the heart.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

TetraGraph monitoring

Subject scheduled to undergo an elective surgical procedure will have TetraGraph device lead placement on either hand at a discretion of the anesthesiologist

Group Type EXPERIMENTAL

TetraGraph

Intervention Type DEVICE

FDA approved neuromuscular transmission monitor capable of measuring the depth of neuromuscular block in anesthetized patients who received neuromuscular blocking agents. TetraGraph uses EMG to measure the muscle action potentials that are generated in response to electrical neurostimulation via skin electrodes.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age \> or = 18 years old.
* Patients willing to participate and provide an informed consent.
* Patients undergoing an elective surgical procedure requiring administration of rocuronium, and the use of a pulmonary artery catheter intraoperatively.

Exclusion Criteria

* Patients with unilateral disorders, such as stroke, carpal tunnel syndrome, broken wrist with nerve damage, Dupuytren contracture.
* 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.
