“…Setup of monitoring equipment was performed in parallel with standard setup for ablation interventions to prevent increase in procedure time. Criteria for abnormal neurotonic activity were those recommended by the American Society of Neuromonitoring 8 . Somatosensory evoked potential (SSEP) amplitude changes of greater than 50% or prolonged latency greater than 10% from baseline were considered significant.…”

Purpose To assess feasibility of intraoperative neurophysiologic monitoring (IONM) during image-guided, percutaneous thermal ablation of tumors. Materials and Methods From February 2009 to October 2013, a retrospective review of all image-guided percutaneous thermal ablation interventions using IONM was performed and data was compiled using electronic medical records and imaging studies. Results Twelve patients were treated in 13 ablation interventions. In 4 patients, real-time feedback from the monitoring neurologist was used to adjust applicator placement and ablation settings. IONM was technically feasible in all procedures and there were no complications related to monitoring or ablation. All nerves at risk remained intact and of the 11 patients who could be followed, none developed new nerve deficit up to a minimum of 2 months after ablation. Conclusion IONM is safe and feasible for use during image guided thermal ablation of tumors in the vicinity of nerves. Outcomes in this study demonstrate its potential utility in image guided ablation interventions.

“…Monitoring sensory functioning while performing a procedure on the somatosensory cortex is essential to minimize any loss of sensory function, to prevent accidental clipping of a critical vessel, and to prevent lesions to important brain regions [3]. The CsM can be utilized during the surgical procedure involving but not limited to epilepsy, arteriovenous malformations (AVM), aneurysms, embolism, and brain tumors.…”

Intraoperative sensory cortical mapping is a reliable and safe method for the functional localization of the central sulcus (CS). It is utilized during neurosurgical procedures performed near eloquent brain tissue. It helps in identifying the somatosensory cortex and CS, hence preventing any postoperative neurological deficits. When executed properly, this method can identify the somatosensory cortex for both the upper and lower limbs by locating the CS. This technical report outlines the benefits of cortical sensory mapping (CsM) and detailed methodology. With the help of a properly trained intraoperative neuromonitoring staff who can accurately interpret the signals being monitored, CsM can help in injury prevention during brain surgeries.

“…The particularity of evoked potentials rests in their capability to monitor spinal cord function and indirectly monitor its metabolism [13]. By the judicious use of electrode montage, evoked potentials may inform about nervous conduction through the whole CNS until the different cerebral cortical lobes [69]- [71]. Similarly, their analysis may be global or segmental, and they can be divided into conduction index (subcortical) and in function index (cortical), as detailed in Table 4 and Table 5 [72].…”

Monitoring the metabolism and function of the central nervous system not only is an old idea but also is a topic that is of increasing interest to the technological evolution. Beside the optimization of cerebral and spinal cord perfusion and the preservation of vasoreactivity to ensure the viability of cerebral tissues and structures, we want to know more and more about the real intimate situation of these organs in real time at the patient's bedside. To this end, several tracks have been explored during the two last decades, leading to the development of numerous concepts and the conception of various monitoring systems. One of the main problems is to characterize the respective strong points and weaknesses of those ones and to conclude regarding their individual relevance and value in current clinical practice. It is more and more clear that the combination of different categories of monitoring is a way to try to find the most valuable technological compromise, to increase the chance of prediction or of early detection of intercurrent deleterious events corresponding to the concept of multimodality. The intraoperative period and the intensive care goals and targets are appreciably different. This is the reason for the attempt to define different and distinct sets of goals and targets for the intraoperative anesthetic setting and for the intensive care unit.
