Book Synopsis The Cerebral Circulation by : Marilyn J. Cipolla
Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

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.

Book excerpt: This Brief provides a comprehensive introduction to the control of blood flow in the brain. Beginning with the basic physiology of autoregulation, the author goes on to discuss measurement techniques, mathematical models, methods of analysis, and relevant clinical conditions, all within this single volume. The author draws together this disparate field, and lays the groundwork for future research directions. The text gives an up-to-date review of the state of the art in cerebral autoregulation, which is particularly relevant as cerebral autoregulation moves from the laboratory to the bedside. Cerebral Autoregulation will be useful to researchers in the physical sciences such as mathematical biology, medical physics, and biomedical engineering whose work is concerned with the brain. Researchers in the medical sciences and clinicians dealing with the brain and blood flow, as well as industry professionals developing techniques such as ultrasound, MRI, and CT will also find this Brief of interest.
Book Synopsis The Physiology and Pharmacology of the Microcirculation by : Nicholas Mortillaro
Download or read book The Physiology and Pharmacology of the Microcirculation written by Nicholas Mortillaro and published by Elsevier. This book was released on 2012-12-02 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physiology and Pharmacology of the Microcirculation, Volume 1 discusses the biochemistry, metabolism, pharmacology, and physiology of the general microcirculation. This volume is organized into nine chapters that explore the microcirculation in several organ systems, such as brain, eye, heart, and kidney. The introductory chapters treat the biochemistry of isolated elements of the microvasculature, with special emphasis on the central nervous system. These chapters also explore the microvascular element and the vascular smooth muscle, focusing on their ultrastructural characteristics, innervation, and contraction-relaxation, and the effects of both endogenous and pharmacological vasoactive substances on vascular smooth muscle. The subsequent chapters deal with the exchange mode of the microcirculation; the mechanisms involved in the regulation of transcapillary fluid exchange; and the permeability of capillaries to small and large molecules in a variety of tissues. A discussion on the control mechanisms modulating microcirculatory dynamics is also included. The remaining four chapters are organized to deal with the microcirculation process in selected organs.

Book Synopsis Local Control of Microvascular Perfusion by : Michael Hill
Download or read book Local Control of Microvascular Perfusion written by Michael Hill and published by Biota Publishing. This book was released on 2012-10-01 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Local control of microvascular perfusion refers to the ability of individual tissues to maintain a relative constancy of hemodynamics in the face of changing perfusion pressure while meeting metabolic demands appropriately. The regulation of local blood flow, or autoregulation, and its underlying mechanisms have been a subject of considerable interest for over 100 years. Particular focus has been placed on the acute interaction of myogenic (pressure-induced) and metabolic (local production of vasodilator metabolites) parameters and how they interact with flow (shear stress)-dependent and conduction-based mechanisms to produce integrated local vascular network responses (for example, as seen during reactive and functional hyperemia). This monograph discusses each of these vasoregulatory phenomena while also considering evidence for their underlying cellular mechanisms. Further, an attempt is made to integrate the information into complex in vivo situations and consider their relevance to pathophysiological situations.
Book Synopsis Monitoring of Cerebral Blood Flow and Metabolism in Intensive Care by : Andreas Unterberg
Download or read book Monitoring of Cerebral Blood Flow and Metabolism in Intensive Care written by Andreas Unterberg and published by Springer. This book was released on 2012-02-28 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, monitoring of cerebral blood flow and metabolism was an unattained goal. Determination of cerebral blood flow was limited to intermittent measurements and particularly difficult to perform in critically ill patients. Meanwhile there are techniques available, however, to monitor cerebral blood flow and cerebral oxygenation, both globally and regionally. Therefore we thought it worthwhile to discuss these new continuous techniques and to compare them with well-known techniques which discontinuously measure CBF. For that purpose, an international workshop with some leading experts in the field was held in October 1992 in Berlin. The workshop consisted of about 20 lectures, either reviews on a special topic, or latest results. These contributions were given by invitation and were extensively discussed. Unfortunately it is impossible to reproduce the discussions. On the other hand, all speakers delivered a manuscript promptly after the meeting so that we were able to edit them within a short time. Since monitoring of cerebral blood flow in intensive care is a rapidly growing and changing topic, the written contributions should be quickly available. Authors, editors and publishers have tried to come close to this ideal. As editors we would like to thank the authors and the publishers who enabled us to come out with this volume of the proceedings as early as possible.

Book Synopsis Transcranial Doppler Sonography by : Rune Aaslid
Download or read book Transcranial Doppler Sonography written by Rune Aaslid and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every few years a dissertation comes to the area of clinical application of medical technology which carries us forward as on a magic carpet into new regions of understanding and patient care. This book is such a magic carpet. It brings together, in a clear and incisive fashion, important hemodynamic principles with a simple noninvasive method of application to a part of the cerebral vasculature which has been relatively inaccessible. To the lucky and perceptive person who reads this book, a feeling of excitement and hope for progress is engendered. The diligent application of the potentials of transcranial Doppler ultrasound brings new power to our efforts in understanding the cerebral circulation and the causes, treatment and prevention of cerebrovascular disorders. Merrill P. Spencer, M. D. Director Institute of Applied Physiology and Medicine Seattle, Wash. , July 1986 Acknowledgements I am greatly indebted to Prof. He1ge Nornes, Oslo, who introduced me to the fascinating study of cerebral hemodynamics in the early 1970's and since then continually encouraged my interest in this field. It was through his pioneering work on the cerebral circulation-using peroperative electromagnetic flowmetry and Doppler techniques-that the basis was laid for the noninvasive trans cranial approach to the circle of Willis described in this book. I also gratefully acknowledge the stimulating case discussions with Prof. Peter Huber, Berne, at the very early introduction of trans cranial Doppler, the inspiring exchange of ideas with Dr. Merrill P.
