Advances of cardiovascular engineering prompt one to consider innovative device technology - that is, the development of new replacement heart valves or engineering of a totally implantable energy source for an artificial heart. However, these kinds of advances have often proved unable to achieve a long-lasting benefit as the cardiovascular field has matured so fast. Cardiovascular engineering has matured to the point where a major innovation must not only function, but must continuously function better than existing devices. This is difficult to accomplish in the complex cardiovasculature system, in which energy source, biocompatibility, compliance, and functionality all must be considered. The maturation of the field is evident from the fact that many engineered prosthetic systems perform well - for example, heart valves function for long periods of time, large-vessel vascular grafts are quite adequate, extracorporeal membrane oxygenation has significantly prolonged the feasible length of heart bypass and other surgical operations, and total artificial hearts can be used as a bridge to transplant without serious complications, yet none of these systems is as good as the natural ones it replaces. The reasons for this are many and incompletely understood. The next stage of progress must be better to alterations understandings of the various components of vasculature and their response by our devices, be they at the micro- or macro-circulatory levels, in the blood, or associated with the vascular wall.

This book fills the void to provide a comprehensive review of the theoretical knowledge and scope of opioid pharmacotherapy in pain medicine. While the information provided is obtainable in other major texts already in print, the present format style plus the illustrations will make easy reading and fast accessibility of information on opioids available. Information provided is based on clinical practice rather than pure experimental for use in daily practice.

The publication of the Vth International Symposium 1995 on "Mechanisms of Secondary Brain Damage" in Mauls/ltaly is a collection of focused reviews reaching from novel molecular- and cell biological findings to aspects of clinical management in head injury and cerebral ischemia. A specific purpose of these series of meetings introduced in 1984 is for an exchange on problems of mutual interest by international high ranking experts from the basic sciences and related clinical disciplines, such as intensive care medicine, neurology, or neurosurgery. The present volume covers three major areas: (a) Molecular and cell biological mechanisms including inflammation (b) Novel findings on mechanisms and treatment in cerebral ischemia (c) Secondary processes in head injury, regeneration and treatment Molecular-and cell biology is currently attracting attention towards activation of genomic processes associated with the demise of cells referred to as "programmed cell death" and "apoptosis" which, actually, might be distinguished from each other. Thus, the phenomenon of delayed neuronal death in selectively vulnerable brain areas following brief interruption of blood flow is scrutinized as to the contribution of the activation of suicide genes. The physiological role of such a response, among others, is removal of surplus neurons during ontogenesis of the brain. Yet, evidence is accumulating that similar mechanisms playa role in cerebral ischemia, probably also trauma, where nerve-and other cells demonstrate features of apoptosis. Observations on protection of neurons by administration of protein synthesis inhibitors in cerebral ischemia provide more direct support.

This book has been written for the general health care professional, from every medical and paramedical specialization. Because pain is the most common factor driving patients to seek professional advice, it is likely that every physician, psychologist, and therapist has been clinically exposed to the difficulty and the frequent frustration of dealing with people in pain. All of them may find in this book some explanations for their puzzles and some updated information, which usually are published in specialized journals not ordinarily read by the general practitioner. Actually the book has been addressed to professionals at two different levels of general practice. At one level is the busy practitioner who treats most patients with' 'acute" pain, and who may use this information in daily practice to prevent the onset of chronic pain; a common effort from all professionals currently is needed to curb the "epidemic" of chronic pain in the United States. At another level the book has been addressed to the practitioner who may have a more intense desire to become involved in the actual management of chronic pain patients.

25 years have passed since a small group met for the First International Symposia on Brain Edema in Vienna. Subsequent Symposia were held in Mainz, Montreal, Berlin, Groningen, Tokyo and Baltimore. During this time we have witnessed a virtual explosion of the number of publications in this field and our basic and clinical understanding of this disease process has increased tremendously. Our meetings have always been a landmark to take stock of our experience so far and to provide perspectives toward future developments. In addition, it always was a good opportunity to renew old friendship and to make new friends. This volume is a compilation of papers presented at the Eighth International Symposium on Brain Edema held on June 17-20, 1990 in Bern, Switzerland. During this Symposium 158 papers were presented as oral or poster presentations. This considerable number of papers was chosen from more than 230 abstracts that were received. The organizers wish to thank the Advisory Committee for the work done in paper selection and focus on the Symposium. Appreciation is also given to all persons, who have contributed to the success of this meeting, the Chairmen, the participants and last but not least all the staff who worked behind the scene.

Sepsis is still the leading cause of death in surgical and general intensive care units. Although our knowledge of this complex syndrome has increased in recent years, it is still far from com- plete. New therapeutic approaches have been developed. Some did not fullfill the high expectations for their use in clinical prac- tice; others are still under clinical evaluation. is the aim of this monograph to offer basic information on the It etiology, definition, pathophysiology, prevention and therapy of sepsis and septic shock to both the clinician and the scientist. We believe that it presents an extensive overview that may help the clinician to better understand and treat sepsis and septic shock. We also hope that this work will give some directions for future research both in the clinical field as well as the laboratory.

Leading investigators critically evaluate the latest information on how anesthetics work at the molecular, cellular, organ, and whole animal level. These distinguished experts review anesthetic effects on memory, consciousness, and movement and spell out in detail both the anatomic structures and physiological processes that are their likely targets, as well as the cellular and molecular mechanisms by which they operate. Comprehensive and authoritative, Neural Mechanisms of Anesthesia draws together and critically reviews all the recent research on anesthetic mechanisms, highlighting the precise routes along which these substances operate, and how this deeper understanding will lead to the design of effective drugs free ofundesirable side effects.

During the last decade a multitude of studies concerning the dynamic changes in cerebral blood flow (CBF), cerebral metabolic rate of oxygen (CMRO2), and intracranial pressure (ICP) in the acute phase after head injury have been published. These studies have been supplemented with studies of cerebral autoregulation, CO2 reactivity and barbiturate reactivity. Other investigations include studies of cerebrospinal fluid pH, bicarbonate, lactate and pyruvate. In this book experimental and clinical studies of the dynamic changes in CBF, CMRO2, CO2 reactivity and barbiturate reactivity are reviewed. The author's own clinical studies of the dynamic changes in CBF and cerebral metabolism are summarized and discussed, and the therapeutical implication as regards the use of artificial hyperventilation, sedation with barbiturate and mannitol treatment are discussed.

Before the late 1970s, interest in caffeine among both the general public and the scientific community was at a relatively low level for many years, even though it was recognized that caffeine was an al most universal component of the diet. The National Coffee Associa tion was supporting a continuing program of research, some re search was being conducted by a few of the largest companies selling coffee, and an occasional university researcher became inter ested in caffeine and conducted experiments, often on effects of caf feine in very high concentration in vitro on skeletal muscle fibres or on dividing cells. Since 1978, however, there has been a mighty up surge in both public and scientific interest in caffeine. It is interest ing to note that this was prompted not by discovery of hitherto un known effects or hazards of caffeine, but by the actions of a regulatory agency, the Food & Drug Administration (FDA) of the U. S. Public Health Service. The U. S. Congress passed new laws on foods and drugs in 1958. One of the provisions was for testing of food additives to assess risk to health. As it was clearly impracticable to require immediate test ing of all additives already in use, a list was drawn up of some hun dreds of additives that were generally recognized as safe (GRAS)."

Geriatric anesthesia is a rapidly growing and evolving field. The last few years have seen significant advancements in and important new modalities for addressing the needs of an aging population. The editors of Geriatric Anesthesiology's second edition are uniquely situated to put together a text highlighting both essential knowledge and recent breakthroughs of importance to any who work with the elderly. For the second edition, the editors have introduced a streamlined chapter format and have assembled a selection of chapters intended to deepen the understanding of anesthesic management of the geriatric patient.

The decisive factor in trauma is that many processes first occur at the cellular level before they can be determined in laboratory tests, and recognition of them has only recently found its way into intensive care practice. Yet knowledge of the pathophysiology of these processes is essential for an early diagnosis of multiple organ failure and the implementation of adequate therapy, which ultimately make the patient's survival possible. Professor Schlag, an internationally renowned scientist and clinician, has been concerned with the basic pathophysiological principles of shock for many years. In this book he has brought together for the first time an international team of authors primarily from the USA and Europe, who present their collective findings of trauma, shock, development of the organ in shock and early failure and of sepsis-like syndrome, and development of septic multiple organ failure. Patienten mit Multiorganversagen haben immer noch eine schlechte Prognose in der intensivmedizinischen Behandlung, insbesondere wenn sie noch zusatzlich in einen septischen Schock geraten. Hier hilft auch oft eine breite Abdeckung mit modernsten Antibiotika nicht weiter. Neue Ansatze fur eine Therapie dieser problempatienten haben sich in den letzten Jahren durch Erkenntnisse der pathophysiologischeen Vorgange die zum Schock fuhren ergeben. Herr Professor Schlag hat als anerkannte Kapazitat auf dem Gebiet der Traumatologie und Schockforschung fur dieses erste umfassende Werk zu den Grundlagen des Multiorganversagens eine beeindruckende Liste von mehr als 50 international renommierten Autoren zusammenbekommen. Das Buch ist nicht nur eine Aufarbeitung aller Grundlagen des Schocks und Multiorganversagens sondern zudem ein ausgezeichnetes Nachschlagewerk fur jeden intensivmedizinisch tatigen Klinikarzt, egal ob er aus der Anasthesie, der Inneren Medizin oder der Unfallchirurgie kommt."

Dieser Band gibt die Referate des 4. Internationalen An{sthesie-Symposiums, 15.-17. Juni 1989 wieder. Amerikanische und europ{ische Spezialisten der unter- schiedlichsten Fachgebiete diskutieren neueste Entwicklungen der Labor- und klinischen Forschung.

Perinatal medicine, which is concerned with the problems of the fetus and newborn, has rapidly developed in the last two decades as an important and challenging specialty. Rapid advances in the field, coupled with tech nological advances, now are making survival of infants with weights as low as 500 grams possible. Ventilator care for severe respiratory problems is on the verge of being replaced by surfactant replacement therapy; on the other hand, development of such technologies as extracorporeal mem brane oxygenation and jet ventilation has revolutionized the care of these sick infants. The advances taking place today in the field of perinatal medicine make periodic updates, like the one provided by this volume, a virtual necessity for clinicians and paramedical personnel alike. A distinguished group of specialists in various aspects of perinatal medicine has contributed to this book. Their wide-ranging experience and points of view should make this book a valuable reference for all physicians and allied health personnel involved in the care of the high-risk fetus and newborn. MANOHAR RATHI, M.D. Acknowledgements.

Pain is unfortunately not an early symptom in neoplastic diseases. When it occurs, however, as it so often does in the advanced stages of the disease, then it can be particularly severe. Many physicians are not able to treat such pain efficiently with the standard methods familiar to them. Even in the oncological clinic, it is common for cancer patients not to receive adequate treatment of their pain; the therapeutic efforts are directed principally at the cancer, the pain often being neglected. This book fills a gap in the literature and should enhance the awareness of pain of all those who deal with cancer patients. For the patient, the symptoms of the disease are usually the direct cause of suffering, and pain is often the most severe symptom. The pain may be potentiated by knowledge of the threat posed by the cancer, or may itself considerably increase the patients existing anxiety. Thus there is a vicious circle of pain and psychological factors which will reduce the patient to a state of despair and distress. It is, therefore, obvious that efficient pain therapy is of utmost signi ficance to the patient, who will judge the doctor's ability to provide medical assistance according to the degree of pain relief achieved. The patient's quality of life will also depend critically on the relief obtained."

This volume is a compilation of papers presented at the Tenth International Symposium on Brain Edema held on October 20-23, 1996, in San Diego, California. This follows the sequence of meetings that was initiated 31 years ago in the First International Symposium held in Vienna. Subsequent symposiums were held in Mainz, Montreal, Berlin, Groningen, Tokyo, Baltimore, Bern, and Tokyo CY okohama). A considerable number of papers was chosen from over 100 papers that were received. The organizers wish to thank the Advisory Committee for the excellent work done in selection of the papers. We also wish to thank all the persons who contributed to the success of the Tenth International Symposium, especially the staff who worked behind the scenes. These papers were reviewed, edited, approved or disapproved by the Editorial Board. Those manuscripts that were felt not pertinent to this publication were not accepted by the Editorial Board. Therefore, the excellent quality of those that are in the book are a reflection of the authors' dedication and work and that of those of the Editorial Board in their review process. For the reader's convenience, the papers are structured according to the various disease processes which are associated with the primary topic: hypertension, hydrocephalus, infection, ischemia, tumor, etc. We do hope that the reader will enjoy the articles and that they will provide an impetus and insight for future work.

Local anesthetics are among the most widely used drugs. Their development over the past century ranges from a documented influence on Freud's Interpretation of Dreams 1 to the synthesis of the ubiquitously popular lidocaine, as described in Chapter 1. For surgical procedures the use of regional, epidural and intrathecal local anesthesia has increased continuously during the past decade. Local anesthetics are also applied by physicians to ameliorate unpleasant sensations and reactions to other procedures, such as tracheal intubation. The presence or the threat of cardiac arrhythmias is often countered by chronic administration oflocal anesthetic-like agents, such as lidocaine or procainamide. Relief of acute pain, accompanying dental manipulations, for example, and of chronic pain are also accomplished with traditional local anesthetics. And over-the-counter formula tions of topical local anesthetics provide practitioners of solar indiscretion welcome relief from their otherwise unaccommodating sunburn. In all these applications the final effect of the local anesthetic is an inhibition of electrical activity, accomplished as a reduction or total blockade of action potentials. The primary site of action is the sodium channel, a transmembrane protein which is essential for the influx of sodium ions that subserves impulse generation and propagation in nerves, skeletal muscle, and heart. The detailed mechanisms oflocal anesthetic action are still being investigated and Chapter 2 of this volume provides a current overview of that subject."

In January 1980, the First Symposium on the Measurement of Tis sue Oxygen Pressure in Patients was held in Frankfurt. After a 4-year "rest period," the organizers of the 1984 symposium, Profes sor R. Huch of Zurich and Dr. J. Hauss of Munster, together with myself, extended another invitation to come to Frankfurt to find out what had gone on in the field of oxygen pressure measurement and its application in clinical medicine. As the following presentations will show, the application of oxygen pressure measurements has been broadened considerably. Furthermore, technological advances have been made, particularly with the increased use of computers. For various reasons, including technical ones, these methods have not been adapted as widely as one would want. Although con gresses on tissue oxygen pressure have been held in the last few years, the clinical aspect of tissue P0 measurement has not been 2 dealt with in such a concentrated and comprehensive way since 1980. It therefore seemed necessary to hold such a symposium, not only for scientific reasons, but also to enable a larger group of clini cians to gain insight into the importance of the possibilities these methods offer."

Successful pain management is key to patient quality of life and outcomes across many fields of medicine. The Handbook of Pain Management provides an insightful and comprehensive summary, authored by a noted expert.

Concise and insightful review of an important and complicated area of medicine

Are you looking for the essentials you need to learn the basics of echography for anesthesiology, intensive care and emergency medicine? This is what this book offers you! These few pages condense the essential knowledge to make getting started with echography in emergency situations easier. Ultrasounds are presented in great detail in order to facilitate and optimize the medical diagnosis process. As a doctor, you will first be placed in front of the machine in order to take the pictures that will serve to answer the questions asked. Just as the author did, you will realize that, when facing the patient with the machine, the best echographic examination is worth nothing without a good clinical examination. As a "beginner's guide", this book also offers self-training procedure that lays the foundations of the "FAST" learning method. This FAST Program of Echography allows you to learn the process by watching, feeling and talking. This training course is based on an ancient methodology that centers on the learning of a manual gesture: 'practice makes perfect'. This book will show you that you can quickly master this Program of Echography, and will in turn increase your self-confidence when taking care of your patients. Have a nice trip through the fascinating world of ultrasounds!

Chronic and persistent pain, which is a problem for the individual who suffers and the society that has to deal with it, has become increasingly appreciated. Over the last three decades, several books and journals have been specifically devoted to the topic of pain, especially chronic and persistent pain. It has been increasingly recognized that chronic and persistent pain, unlike acute pain, involves significant psychosocial factors and requires treatment strategies that deal with these issues. All measurements and factors that affect improvement seem to be in the psychosocial area rather than the medical/ biological/physical areas. Psychosocial conveys the importance of the environmental and interpersonal factors of the patient's functioning. The writing of this book has brought together some of the leading researchers and clinicians in the area of managing the patient with chronic pain. The authors express their opinions based on experience and review of the literature available to date. Each of the chapters focuses on an important element of the assessment and/or treatment intervention utilized for the individual with chronic pain. The concluding chapter summarizes the status of the assessment and treatment strategies for those patients.

Contrary to common belief, infectious diseases are not as well under control as we would like. We are now at a crossroads regarding the impact of the environment on infectious diseases. Renewed interest in biological weapons and the emergence of new pathogens, coupled with a better understanding of the impact of infectious agents on other conventional diseases, has led us to realise that we can no longer remain complacent about the impact of infectious agents on human, animal and crop health. The present book first discusses current and emerging military and civilian policies on the environment. In addition, the impact of environmental biology on the future of space exploration is discussed, especially in reference to the Mars mission. There follows a discussion of the state of bacteria in the environment, with a presentation of current and emerging techniques of microbial investigation. Finally, two case studies are presented on the impact of these techniques on both political and environmental problems.

Theodore H. Stanley, M. D. Anesthesiology and the Heart contains the Refresher Course manuscripts of the presentations of the 35th Annual Postgraduate Course in Anesthesiology which took place at The Cliff Conference Center in Snowbird, Utah, February 16-20, 1990. The chapters reflect new data and concepts within the general framework of "evaluating myocardial function," "pharmacology and the cardiac patient," "anesthesia for patients with cardiac disease," and "stress, cardiopulmonary bypass, coagulation problems and related issues. " The purposes of the textbook are to 1) act as a reference for the anesthesiologists attending the meeting, and 2) serve as a vehicle to bring many of the latest concepts in anesthesiology to others within a short time of the formal presentation. Each chapter is a brief but sharply focused glimpse of the interests in anesthesia expressed at the conference. This book and its chapters should not be considered complete treatises on the subjects addressed but rather attempts to summarize the most salient points. This textbook is the eighth in a continuing series documenting the proceedings of the Postgraduate Course in Salt Lake City. We hope that this and the past and future volumes reflect the rapid and continuing evolution of anesthesiology in the late twentieth century. vii LIST OF CoNTIUBUTDRS Bailey, P. L.

Thoracic anaesthesia is regarded as a post fellowship sub-speciality within anaesthesia, and can be daunting. This handbook provides an easily accessible, informative, and palatable guide to this often complex subject. The text is sub-divided into basic sciences, pre-operative assessment, diagnostic procedures, and an anaesthetist's walk-through of key thoracic surgical procedures. It concludes with an emergency section covering thoracic anaesthesia emergencies, critical care, and the thoracic surgical patient, and ends with essential guidance on the relevant practical procedures necessary to manage cases. The text provides an essential reference for the core curriculum of the Fellowship of the Royal College of Anaesthetists and for the day-to-day practice of post fellowship anaesthetists alike. The discussions of the surgical procedures are simple, highlighting the poignant stages that can affect the anaesthetic management of the patient. The authors use the very latest evidence in order to keep the reader up to speed with developments in the field. Whether on-call, running day-to-day lists or working within critical care, this indispensable guidebook will optimise the preparedness of all staff in dealing with any case, whether simple or complex.
