Study 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.

Read the detailed 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.

  3. Patients must be capable of understanding the and have signed the informed consent document prior to any study-specific screening procedures or evaluations being performed.

Exclusion criteria

Exclusion Criteria:

  1. Patients ≥ 70 years of age

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Study arms

  • Experimental
    Autonomic nervous system monitoring

    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 all patients who consent to participate in the study. EMG data and additional demographics and clinical data (e.g. operative time, adverse events) will be collected for each patient.

    Device: Autonomic nervous system monitoring

Interventions

  • DeviceAutonomic 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.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: Duration of surgery

Secondary outcomes

  1. 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.

    Time frame: Duration of Surgery

  2. The believable and repeatable smooth muscle EMG response, if any, measured by amplitude and frequency after deliberate spinal/extra-spinal neural stimulations.

    Time frame: Duration of surgery
