  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study

The goal of this study is to determine the optimal stimulating and recording protocol for visual evoked potentials (VEP’s) during non-cranial surgery using total intravenous anesthesia (TIVA). The study will also determine if VEP’s remain reliably stable in amplitude and latency during non-cranial surgery using total intravenous anesthesia (TIVA), and also determine what factors predict poorly reliable VEP’s during non-cranial surgery using TIVA.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
