TY - CHAP M1 - Book, Section TI - Evoked Potentials in the Operating Room and ICU A1 - Gordon, Errol A1 - Claassen, Jan A2 - Lee, Kiwon PY - 2012 T2 - The NeuroICU Book AB - Evoked potentials are well established as diagnostic and monitoring tools in the operating room (OR) as well as the intensive care unit (ICU) setting. They may help clinicians to detect injury to peripheral nerves and the spinal cord during surgery, and help prognosticate outcome after traumatic brain injury (TBI) and cardiac arrest.A 55-year-old woman complained for several years of neck stiffness and pain for which she was medicating herself with nonsteroidal anti-inflammatory drugs. Over the past several months, she noted having more difficulty getting around and increasing clumsiness. She denied any bowel or bladder symptoms. Her examination revealed increased tone in all of her extremities with bilateral positive Babinski signs and sustained ankle clonus. Strength was full power on confrontation testing throughout. No sensory level was appreciated. Her primary care physician sent her for a computerized tomographic (CT) scan of the cervical spine, which revealed significant spondylosis and canal stenosis that was worse at C5-C6 and C6-C7, with posteriorly displaced discs. A cervical magnetic resonance image (MRI) revealed cord compression with cord signal changes at C5-C6. After getting these results, the primary care physician referred her to a local orthopedic surgeon who recommended decompression of C5-C6 and C6-C7. He mentioned that he will be using intraoperative neurophysiologic monitoring during the case.
