Diagnostic accuracy of somatosensory evoked potential and electroencephalography during carotid endarterectomy.
Perioperative stroke risk following carotid endarterectomy (CEA) is reported to be approximately 2-3%. The diagnostic accuracies of intraoperative EEG and SSEP monitoring during CEA have been studied separately. However, to date, the effectiveness of simultaneous EEG and SSEP monitoring during CEA has only been evaluated in small study populations. This study examined the diagnostic accuracy of combined EEG and SSEP monitoring in a large (N = 1165) patient population. ⋯ The diagnostic accuracy of multimodality IONM during CEA is higher than an approach using single modality IONM. Simultaneous EEG and SSEP monitoring improves the likelihood of detecting periprocedural strokes after CEA. Neuro protective therapies to prevent periprocedural strokes can be based on changes in SSEP and EEG during CEA.

A modified procedure for lumbar intrathecal catheterization in rats.
Intrathecal catheterization and drug delivery in rats has always been a very important method for neuroscience and pain research. Although the technique has been continually improved since the first report, the experience gained over the years suggested that some defects remained unsolved. On the basis of modification of the standard epidural needle, lumbar needle, and intrathecal tube, we aimed to develop a simple and practical technique for intrathecal catheterization, which was similar to the 'needle-through-needle technique' used in combined spinal-epidural (CSE) anesthesia. ⋯ We suggest that the modified method of intrathecal catheterization is well suitable for long-term behavior and pharmacology research on spinal cord.
