Available in PDF, EPUB and Kindle. Book excerpt: Evoked potentials are potentials that are derived from the peripheral or central nervous system. They are time locked with an external stimulus and can be influenced by subjective intentions. Evoked potentials have become increasingly popular for clinical diagnosis over the last few years. Evoked potentials from the visual system are used by ophthalmologists in order to localize the abnormalities in the visual pathway. The otologists are mainly involved in brainstem auditory evoked potentials, while the pediatricians, neonatologists, neurologists and clinical neurophysiologists make use of multimodal stimulation. The psychiatrists and psychologists, generally, examine the slow potentials such as P300 and CNV. Anesthesiologists use short latency somatosensory and visual evoked potentials in order to monitor the effectiveness of the anesthesia. Pharmaco evoked potentials are very promising measures for the quan tification of the effectiveness of drug action on the cerebral cortex. Urologists are more and more involved in pudendal somatosensory evoked potentials and in the intensive care unit evoked potentials are used in order to monitor the functional state of the central nervous system of the patient. This overwhelming number of examinations and exam ina tors clearly demonstrates the need for guidelines and standardization of the methods used. The evoked potential metholody is restricted by the relative poor signal to noise ratio. In many diseases this signal to noise ratio decrease rapidly during the progression of the illness. Optimal technical equipment and methodology are therefore essential.

Download or read book Illustrated Manual of Clinical Evoked Potentials written by Aatif M. Husain, MD and published by Springer Publishing Company. This book was released on 2017-08-28 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evoked potentials have been used for decades to assess neurologic function in outpatient studies and are now routinely used in the operating room during surgery. Illustrated Manual of Clinical Evoked Potentials is a modern, practical guide to performing these studies and interpreting the results. The book is uniquely organized as a singular resource that provides the necessary background for understanding and conducting evoked potential studies. It functions as a multi-purpose text, atlas, and reading session, with numerous examples of studies and findings and discussion of key takeaways. Divided into five chapters, the book opens with an introduction to the basics of data acquisition and interpretation that lays the foundation for the modality-specific chapters that follow. The next group of chapters are in-depth reviews of visual, brainstem auditory, and somatosensory evoked potentials. Each of these chapters lays out the specifics of the modality and study protocol with examples to show how things should—and should not—be done. Sample studies with discussions about how to interpret them highlight a particular aspect of normalcy or pathology. Imaging correlates are provided to emphasize salient points and offer perspective. The final chapter is an overview of the use of evoked potentials during surgery with imaging and case discussions to introduce the reader to this very important application. Key Features Detailed review of methodology of evoked potential studies Many examples of actual patient studies with imaging correlates Interpretation of each evoked potential study presented in detail “Reading session”-like discussion of each example Special chapter on evoked potentials in the operating room

Available in PDF, EPUB and Kindle. Book excerpt: Brain dysfunction is a major clinical problem in intensive care, with potentially debilitating long-term consequences for post-ICU patients of any age. The resulting extended length of stay in the ICU and post-discharge cognitive dysfunction are now recognized as major healthcare burdens. This comprehensive clinical text provides intensivists and neurologists with a practical review of the pathophysiology of brain dysfunction and a thorough account of the diagnostic and therapeutic options available. Initial sections review the epidemiology, outcomes, relevant behavioral neurology and biological mechanisms of brain dysfunction. Subsequent sections evaluate the available diagnostic options and preventative and therapeutic interventions, with a final section on clinical encephalopathy syndromes encountered in the ICU. Each chapter is rich in illustrations, with an executive summary and a helpful glossary of terms. Brain Disorders in Critical Illness is a seminal reference for all physicians and neuroscientists interested in the care and outcome of severely ill patients.

Download or read book Advanced Evoked Potentials written by Hans Lüders and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last twenty to thirty years the progressivcly increasing availability of averaging machines has made evoked potential testing available not only in the major neurological diagnostic centers but also in the office of many neuro logists in private practice. This rapid devclopment was closely paralleled by clinical research in evoked potentials and the publishing of books covering in detail the basic techniques necessary to obtain evoked potentials and the main clinical applications of evoked potentials. Less work was done, however, to define some of the general principles underlying the recording of evoked potentials or to analyze critically the recording techniques or the actual prac tical value of the information provided by evoked potential testing. In this book an attempt has been made to cover this gap. It is assumed that the reader has a good understanding of basic recording techniques and is familiar with the main applications of clinical evoked potentials. The main emphasis of the first two chapters is to define with more precision some of the physical principles that inftuence the volta ge distribution and are used for defining the generator sources of evoked potentials. This is followed by a critical analysis of recording techniques and of its main clinical applications. Finally there is one chapter that gives an overview on application of evoked potentials for surgical monitoring. This is a rapidly growing field that also has been covered only incomplctcly in previous publications.
Download or read book Vestibular Evoked Myogenic Potential written by Toshihisa Murofushi and published by Springer Science & Business Media. This book was released on 2009-03-28 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vestibular labyrinth consists of ? ve compartments: the lateral, anterior, and posterior semicircular canals, the utricule, and the saccule. At the beginning of the twentieth century, Robert Bárány proposed the caloric test as a clinical test of the lateral semicircular canal. This test enabled clinicians to assess the individual lateral semicircular canal function easily by using the simple method of irrigating the external ear canal with cold or warm water and observing the induced nyst- mus. We believe that the caloric test was a breakthrough in the ? eld of vestibular research. However, as far as the other compartments were concerned, there was no simple clinical test equal to the caloric test for the lateral semicircular canal function. At the end of the twentieth century, the vestibular evoked myogenic potential (VEMP) test was proposed as a new method for assessing the individual saccule function. This test has some unique attributes. First, it uses sound stimulation, even though it is a test of the vestibular system. This appears to be a contradiction n- rophysiologically. As a result, in its early stages there were controversies conce- ing the origin of the responses. However, such controversies have been overcome by basic neurophysiological studies and clinical studies. Above all, sound sensit- ity of the saccular afferents shown in cats and guinea pigs with single-unit recording methods became the main supporting evidence. Nowadays, VEMP is one of the routine clinical tests for balance disorder.

Download or read book Intraoperative Neurophysiologic Monitoring written by Gloria M. Galloway and published by Cambridge University Press. This book was released on 2010-10-28 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraoperative neurophysiologic monitoring has shown a steady increase in use for surgeries in which neural structures may be at risk of injury. Some of the surgical techniques used carry inherent risks, and these risks have changed the way in which neurophysiologic monitoring has impacted patient safety and quality of care during surgical procedures. It is therefore crucial that those performing and interpreting intraoperative neurophysiologic monitoring are adequately trained. This book is a comprehensive guide to the current practice of intraoperative neurophysiology with chapters on various modalities and clinical uses. Separate chapters devoted to anesthesia, operating room environment, special considerations in pediatrics and the interpretation and reporting of neurophysiologic data are useful and complementary. Questions and detailed answers on the topics covered can be found on the accompanying website for study review. This book will be useful to the trainee as well as the neurophysiologist already in practice.
