head/neck positioning - Answer✔During posterior cervical fusion for spinal stenosis, a global
shift in latency cortical and subcortical tibial and ulnar SSEPS are noted an hour following
exposure. this change could be indicative of
hearing loss - Answer✔what is at greatest risk during resection of CPA tumor
right EEG slowing and Left upper cortical SSEP amplitude decrease - Answer✔You are
monitoring a right carotid. if the patient does not have adequate collateral flow what changes
will you see when the surgeon clamps the artery
decreased beta on side of surgery - Answer✔during Carotid the first eeg change indicating
possible cerebral ischemia is
loss of all waves due to vascular compromise - Answer✔extreme cerebellar retraction during
CPA tumor surgery likely results in
after cross-clamping - Answer✔a stroke associated with a carotid will most likely occur
spinal cord ischemia - Answer✔cerebrospinal fluid drainage through a lumbar drain during
thoracic and thoracoabdominal aortic aneurysyms is to prevent
intersubject variability - Answer✔compared to common peroneal stim, responses from ptn stim
are subject to less
