Multicenter Study
Intraoperative monitoring of carotid endarterectomy by transcranial motor evoked potential: a multicenter study of 600 patients.
This study was to investigate the utility of motor evoked potential monitoring elicited by transcranial electrical stimulation (tcMEP) during CEA in addition to the established median nerve somatosensory evoked potentials (mSSEPs). ⋯ TcMEPs seem to improve postoperative outcome, especially in case of a timely correction of cerebral ischemia.
-
To evaluate the utility of near-infrared spectroscopy (NIRS) and transcranial Doppler (TCD) parameters as potential markers for amnestic mild cognitive impairment (aMCI). ⋯ The reduction of TOI may be considered a new marker for aMCI, especially when combined with the increase of PI in MCA.
-
To determine the percentage change in somatosensory evoked potential amplitude and the duration of spinal cord compression that can be tolerated intraoperatively in a rat model before there are significant post-operative functional deficits. ⋯ This study is an important first step in providing basic science evidence for the establishment of acceptable "alarm criteria" during spinal surgery.
