NCT03409536

Brief Summary

Brachial plexus block is a common regional anesthesia technique which is performed by anesthesiologists to anesthetize the arm for surgery. In this study, we are investigating the relationship between the nerve conduction (induced by brachial plexus block) and the patients' symptoms before and after the brachial plexus block. We will attach a nerve conduction device (SSEP device) to monitor the patients' arm conduction and we will assess the patients' symptoms simultaneously.

    Neurological symptoms (including sensory and motor)

    0-30 minutes after receiving the brachial plexus block

Study Arms (1)

SSEP Monitoring

participants will receive a brachial plexus block for their surgery and will be monitored for brachial plexus injury using the automated SSEP monitor.

Device: SSEP monitoring

Interventions

Participants will be monitored using the SSEP device both before and after induction of a brachial plexus block.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

All adult patients who are scheduled to have elective upper limb surgeries and require a brachial plexus block as part of their standard of care.

You may qualify if:

  • All adult patients who are scheduled to have elective upper limb surgeries and require a brachial plexus block as part of their standard of care.

You may not qualify if:

  • Patients unable to perform a complete neurological examination (e.g. dementia, upper limb fracture).
  • Patients who refuse to participate or unable to provide informed consent.
  • Patients who are contraindicated for SSEP monitoring.
  • Patients who have known pre-existing peripheral neuropathy or brachial plexus injury.
  • Patients who are contraindicated to brachial plexus block.
  • Patients who are not undergoing brachial plexus block for their procedures (e.g. elective C5 nerve root block).
  • Patients who had failed brachial plexus block.
