Clinical Trial Summary

A safety and feasibility study of free-run and stimulated corporal electromyography (EMG) to assess autonomic neural function during spinal and/or pelvic surgery in women and men.


Description:

This is a safety and efficacy trial to assess autonomic neural function monitoring during spinal and/or pelvic surgery.

During standard intraoperative neuromonitoring, additional smooth muscle free-running and stimulated EMG will be recorded from corporal tissues (corpus spongiosum) of male and female genitalia from individual patients. Throughout the duration of the spinal surgery, the neurophysiologist will continuously monitor autonomic function. Smooth muscle free-running (continuous) and stimulated EMG will be recorded.

EMG data and additional demographics and clinical data (e.g. operative time, adverse events) will be collected for each patient. The success rates of 1) credible and safe EMG recording and 2) positive EMG responses to each stimulation method will be calculated.

Study Design

Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Supportive Care


Intervention

Device:
Autonomic nervous system monitoring
Two intracorporal electrode needles will be inserted beneath the skin of the genitalia. After insertion, the electrodes will be secured and connected by leads to two standard neurophysiological devices for differential amplification, display, and storage. Smooth muscle free-running (continuous) and stimulated EMG will be recorded.

Outcome

Type Measure Description Time frame Safety issue
Primary Amplitude and frequency of changes in free-run smooth muscle EMG under varying surgical and anesthetic conditions. Free-run smooth muscle EMG will be monitored continuously throughout the duration of surgery. Any changes in the EMG, as indicated by fluctuations in amplitude and/or frequency, will be recorded. Duration of surgery Yes
Secondary Amplitude and frequency of changes in smooth muscle EMG resulting from the inadvertent effect of intraoperative monitoring stimulations and recordings. Smooth muscle EMG in response to stimulations and recordings will be monitored. Any changes in the EMG, as indicated by fluctuations in amplitude and/or frequency in response to IOMN (intraoperative neuromonitoring) stimulations and recordings, will be recorded. Duration of Surgery Yes
Secondary The believable and repeatable smooth muscle EMG response, if any, measured by amplitude and frequency after deliberate spinal/extra-spinal neural stimulations. Duration of surgery Yes
