New findings involving the brain in traumatic and septic shock and after brain injury are reported in this book, including pathophysiological and pathohistological results. An experimental and clinical approach to treatment is presented together with specific results obtained from the encephalogram and from histopathological study with regard to the immunohistochemistry of toxic lipid peroxidant products. The latest results of clinical and experimental pathophysiology in inflammatory processes after traumatic brain injury and the therapeutic effects of hypertonic fluid therapy are also discussed.

This supplement of Acta Neurochirurgica contains the proceedings of the Ninth Convention of the Academia Eurasiana Neurochirurgica held in Chateau St. Gerlach, Houthem, The Netherlands, 29 July - 1 August 1998. During this convention a three-day symposium on Neurosurgery and Medical Ethics was held. In this time of tremendous technical advancement in medicine in general and neurosurgery in particular, we are liable to lose sight of the sick patient as a human being, and the odds are that he will be the object rather than the subject of our action in the near future. It is a purpose and a task of the Academia Eurasiana Neurochirurgica to recognize this thread and to pay attention to tradition, morality and ethics in neurological surgery. The theme of this convention and the subject of the symposium met this purpose as no other. In the scientific sessions during the first day, the moral backgrounds of medical ethics in the most important cultures and religions in east and west were elucidated by invited experts in this field. A mutual respectful understanding of each other's conception of and belief in ethical principles is a growing necessity in our multicultural societies in both continents. On the second day, the ethical aspects of different fields of neurological surgery were discussed by members of the Academia. In this context, also the internationally much-discussed and much-criticized regulations on euthanasia in The Netherlands were explained.

C. Manni The focusing of general interest and of many disciplines on disaster medicine is an interesting and recent phenomenon in our society. Disasters have by now left the his torical and philosophical sphere and finally entered the operational arena. Modern man, in other words, no longer accepts disasters in a passive and fatalistic manner, but claims to be able to control them like so many other forces of nature. The new approach is aimed at preventing, containing, and remedying the invariably tragic consequences of these events. The role of medicine in this context is of fundamental importance and is charac terized by two main aspects: application of techniques of intervention appropriately and effectively, and collaboration with the general organization, assuming responsi bility for the protection of health and the treatment of injuries. Following a period of more or less chaotic growth, during which sectionalism and empirical interests prevailed, and localized aspects of this new discipline underwent considerable development, a need is now felt to propose and realize a more com prehensive scientific approach. It has become necessary to identify and to rationally analyze the individual components of this branch of medicine. As in any analysis, the recognition of the "object" of the research is of fundamental importance: hence the title of this first round table: "Types and Events of Disaster."

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."

A workshop was organised in order to achieve multi-discipli- nary review of the pathogenesis and management of acute failure, particularly as it occurs and is managed in intensive therapy units. The book deals with the realities and practicalities of this important area of acute medicine. Each chapter is followed by a discussion, so that a concen- sus view is obtained from an international body of experts.

The 1992 International Yearbook of Nephrology is the 4th in a successful series of yearly books updating practising nephrologists and nephrologists-in-training on rapidly changing areas of nephrology. We were encouraged to proceed in our editorial venture by reviews of the previous issues which have appeared in various Nephrology Journals. These reviews have pointed to the successful use of the International Editorial Board, the broad range of topics of current interest which have been covered and the comprehensive and practical nature of the reviews. The principal aim of the Yearbook remains to provide reviews which are more current than those which appear in Nephrology textbooks and which can be in the hands of the readers a few months after the authors have completed the manuscripts. The appointed authors are always experts in the field, who are asked to give an objective review of the topic, up-dating the readers on the world-wide literature and providing them with a complete, accurate and up-ta-date list of important recent references. We have decided to maintain the successful format of the first three issues. Thus, the volume will continue to be divided into sections; each section will continue to have a different primary focus every year, depending upon what is of greatest interest at the time.

Sepsis and Innovative Treatment: The Odyssey R. C. Bone The Odyssey by Homer, dates back to the 8th century, B. C. [1]. It is a great epic adventure of Odysseus's dramatic journey from Troy back home to Ithaca. Odysseus survives the ordeals of this journey and returns with new powers and insights. The study of the pathogenesis and treatment of sepsis has also been an odys- sey. I feel we will return from this odyssey with new insights and treatments. However, as with Odysseus, this will occur only after considerable struggle. In the 1980s we had a rather simplistic view of sepsis. It was a highly lethal complication caused by infection and often charac- terized by shock and multi-organ failure. Our knowledge of the inflammatory responses associated with sepsis was embryonic compared to today. The inflammatory response was often treat- ment with mega-dose corticosteroids along with fluid resuscita- tion, vasopressors and antibiotics. Because of the paucity of mul- ti-center controlled trials documenting the risk/benefit ratio of the treatment of sepsis with corticosteroids, two large multi-cen- ter controlled trials were organized to evaluate the role of corti- costeroids in sepsis [2, 3]. Because animal models showed bene- fits of corticosteroids only with pre-treatment or early treatment, a definition of sepsis was used that did not require positive cul- ture documentation or septic shock to be included in the studied population.

It gives me great pleasure to have this opportunity to write a Foreword for this new book. In the past two decades we have witnessed very significant advances in the management of the very ill patient. The great success in this field of medical endeavour is largely due to the establishment of intensive care units, but a great deal of progress can also be attributed to the major developments in technology, which affect patient management and care as well as the many sophisticated techniques of diagnosis and patient monitoring. Imaging and Labelling Techniques in the Critically III covers this new important and difficult field of diagnosis and visual monitoring. By establishing the criteria and algorhythms for the choice of the different methods available for this purpose, defining the diagnostic signs on images and resolving some of the mis conceptions and pitfalls, this book will go a long way to help the reader, particularly those involved in the care of patients in the intensive care units. This book brings together many different methods of investigation and discusses the advantages and limitations of these techniques in different clinical circumstances. Some of the techniques are well established and their usefulness in the intensive care unit is in no doubt. Some of the newer techniques such as PET scanning or NMR imaging have not yet found a defined position of usage in the critically ill patient. There is, however, little doubt that in due course this situation will change.

The acute abdomen is one of the most frequent, most dangerous and most difficult problems that the diagnostic radiologist has to deal with. This comprehensive manual presents a clinico-radiologic approach to the use of diagnostic imaging techniques for acute abdominal conditions. Imaging techniques, radiologic symptoms and clinical conditions are treated separately. This lucid format, together with a detailed subject index, offer the reader a quick and reliable reference aid in daily practice. The text is clearly structured and concise in style, and provides helpful practical hints, including discussion of diagnostic pitfalls. It is supported by a wealth of illustrations covering native diagnosis, ultrasonography, computer tomography and angiography.

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."

This book concentrates on problems generated by acute care in severely traumatized patients during the first 24 hours after injury. During this hectic period, highly complicated problems have to be solved at the site of the accident, during transport to hospital, and in hospital. Multiple medical and paramedical disciplines are involved in providing care to the severely injured. This book endeavors to present a problem-oriented approach to the diagnostic, therapeutic, and organizational aspects that may be encountered.

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.

Sepsis and infection are the major enemies of the intensive care patient in whom immunological defenses are severely impaired. This major problem is thefocus of attention in this book, based on the presentation of the First International Congress on the Immune Consequences of Trauma, Shock, and Sepsis, which is one of the first attempts to exchange ideas on the state-of-the-art in this area of immunology. Both basic and clinical research, including new centres of attention, are described. The growing role of immunology in medicine opens new avenues to the under- standing of trauma and sepsis and will allow the design of novel therapeutic approaches.

The book is based on papers presented at the recently held international meeting on central-nervous-system monitoring in Hamburg, Germany. Experts inthe fields of neurophysiology, experimental and clincial anesthesia and intensive care discussed the state of the art in noninvasive central-nervous-system monitoring. Starting with the principles of CNS monitoring in humans, the topics covered include pharmacokinetic pharmacodynamic interactions, the usefulness of spontaneous and evoked brain electrical activity as an overall-control for afferent systems andfor the assessment of analgesic drug treatment, perioperative anesthesiological monitoring, and intraoperative awareness. Recently developed specific EEG and EP indices such as spectral edge frequency, median frequency, auditory and somatosensory evoked responses for the assessment of depth of anesthesia are evaluated for intraoperative monitoring. The surgical and anesthesiological perspective in intraoperativemonitoring during vascular surgery are presented, as is the state of theart in the monitoring of afferent central-nervous-system pathways by monitoring transcranial motor evoked potentials. Bispectral EEG analysis forthe assessment of anesthetic adequacy represents the future trend in intraoperative monitoring. In addition to neurophysiological methods, assessment of jugular bulb venous oxygen saturation and transcranial Doppler sonography may give additional information for the interpretation of brain fuction. In the field of intensive care, topics in multimodal long-term monitoring of brain function are presented. The application of an expert system supporting the diagnosis of brain death is also included.

Nutritional support of critically ill patients is a major treatment modality which will enhance recovery and shorten convalescence. New knowledge has emphasized that much of the organ dysfunction associated with sepsis and altered blood flow is related to oxidative injury. Specific nutrients are highly effective in counteracting these effects and their early administration may attenuate cellular damage and multi-organ failure. Patient outcome may also be enhanced by the route of feeding, administration of newer nutrient combinations, utilization of evolving methods of monitoring and the use of growth factors. This new knowledge has evolved to a new area of metabolic support which is addressed for the first time by a group of international experts. The topics presented and general conclusions are of major importance to the practitioners in this field, for they show, for the first time, a departure from the more traditional approaches of nutritional support in patients with life-threatening diseases.

Nephrology, initially born as a small branch of medicine, has, in the last few decades, become an extraordinary large field of medicine. The recent development of renal medicine is mirrored by the numerous nephrological journals published, a natural consequence of the increasing number of basic and clinical research studies performed continuously all over the world. Undoubtedly the progress which has occurred in the different, specific fields of renal medicine has given rise to subspecialities which range from renal physiology and pathology to hemo- and peritoneal dialysis and renal transplantation. Even the diagnostic methodology in nephrology, very useful in the clinical practice, has become a speciality within the speciality. Thus, the problem for clinical nephrologists, as well as for internists, is to remain continuously up-dated in all fields of nephrology. Nephrology textbooks are published continuously and in great number. However, the time required for having authors appointed, chapters completed, manuscript edited, galley proofs corrected and the whole book printed makes many textbooks already out of date when they go on sale and their half lives are very short. On the other hand, nephrological journals are so many and the articles so numerous and detailed, that it is often impossible to rely on them for up-dating practicing clinicians.

Echocardiography has been one of the most significant advances in cardiology in the past two decades. It can provide anatomic, functional hemodynamic, and blood flow information. Conventional transtho- racic echocardiography has limitations, particularly in certain patients such as those with obesity, chronic lung disease, or chest wall defor- mity, or in those where a transthoracic approach is difficult for reasons including trauma, life support apparat uses, and surgical dressings. There are also certain disease states or conditions in which transtho- racic echocardiography expectedly gives incomplete or inadequate in- formation. Transesophageal echo cardiography has opened a unique "new window to the heart." The immediate proximity of the esophagus and the posterior heart permits exceptionally high resolution images, par- ticularly of the left atrium, mitral valve, and intraatrial septum. Addi- tionally, from the stomach (trans gastric views), the ventricles can be dependably imaged. Transesophageal echo cardiography presently is utilized in two environments: intraoperatively and for outpatient examinations. Intraoperatively, TEE is utilized to monitor cardiac function and de- tect intracardiac air or debris, to diagnose or quantitate cardiac path- ology, and to access operative results.

The simple reason for creating this book was my impression that the law is having an increasing impact on the practice of medicine. There is hardly a physician I know who has not been deeply troubled by legal problems professionally, economically, and most important of all, psychologically. The past decade has seen medical practice premiums steadily rising. Multimillion dollar verdicts have not been unusual. Having disregarded these vital issues for many years, physicians have suddenly become very aware of litigation-related problems. Having been interested for a long time in the logic ofthe law and the romance of legal research, I thought it would be useful to create a book that would result in the blending of great minds in law and medicine. It has been my long standing observation and belief that the approach of professors of medicine, and that of learned members of the bar and bench, when put together, produce unique results. Putting these views together has been the real challenge in editing this book."

The birth of a baby is the culmination of months of anticipation and plan ning. Most often, mother and infant are healthy and readily able to estab lish close contact-a bond. However, in some situations either mother or baby or both present complications. The more prompt and rational the treatment, the sooner the normal parent-infant relationship will commence. This book is devoted exclusively to the first days following birth. In its 15 chapters, postpartum and postnatal physiology and pathophy i: .;logy are reviewed by 18 specialists. Normal and abnormal development of mother and child is correlated with proven means of clinical management. Chapters 1 through 3 cover maternal postpartum developments and complications. Chapter 4 stresses the importance of a normal parent newborn relationship, a concept of increasing concern in modern society. The following ten chapters discuss neonatal physiology and pathophysi ology; the effects of obstetric anesthesia on infant behavior, pulmonary function measurements in the postnatal period and treatment of the sick newborn are discussed in detail. The final chapter reviews maternal and perinatal mortality; the data, based on extensive surveys in New York City, indicate that current management is effecting an overall decline in mortality."

During the last 20 years two groups of investigators have concerned themselves with the problem of acid-base regulation at various body temperatures. Each group, in professional isolation, pursued a separate path. Surgeons and anesthe tists developed techniques and tools for hypothermic cardio-pulmonary by-pass operations and based their rationale for acid-base management on in vitro models of blood behavior. Physiologists and biochemists, on the other hand, endeavored to understand acid-base regulation in living organisms naturally subjected to changes in body temperature. Only in the last decade has there been an increasing awareness that each group could benefit from the other's experiences. With this goal in mind members of both groups were invited to present their views and observations in the hope of arriving at a better understanding of acid-base management during hypothermia and gaining a greater insight into the factors which control acid-base regulation during normothermia. This led to the presen tation of the present volume with the aim of providing the clinician with a survey of present theories and the resulting strategies for management of the hypother mic patient.

When someone has successfully completed a Standard First Aid Course, they often have a desire to extend their knowledge of first aid. The aim of this book is to give the holders of a Standard First Aid Certificate the opportunity to study the principles of first aid in greater detail. It is not intended to convert the first aider into a highly trained paramedic - so a discussion on the use of intra venous fluids, defibrillators etc., is beyond the scope of this book. It is hoped that the book will provide a useful in-depth study for demonstrators, instructors and first aiders likely to be involved in ambulance duties. I am very grateful to Brigadier D.O. O'Brien, Chief Medical Adviser, British Red Cross Society and Mrs. R.H. Smith, Assistant Branch Director (Training), Leicestershire Branch of the British Red Cross Society for their helpful comments and encouragement. I acknowledge the use of illustrations from the Clinical Symposia Series by CIBA on the "Heimlich Manoeuvre" to form the basis of Figures 3.7,3.8 and 3.9."

The expense of critical care and emergency medicine, along with widespread expectations for good care when the need arises, pose hard moral and political problems. How should we spend our tax d'ollars, and who should get help? The purpose of this volume is to reflect upon our choices. The authors whose papers appear herein identify major difficulties and offer various solutions to them. Four topics are discussed throughout the volume: First, encounters between patients and health professionals in critical situations in general, and where scarcity makes rationing necessary; second, allocation and social policy, including how much to spend on preventive, chronic or critical care medicine, or for medicine in general compared to other important social projects; third, conflicts between or ranking of important goals and values; and fourth, conceptual issues affecting the choices we make. Since these topics are raised by the authors in almost every essay, we did not divide the papers into separate sections within the volume. Warren Reich begins the volume with a parable illustrating a key problem for contemporary medicine and two very different approaches to its solution. His story begins with the "delivery" of three indigent, critically ill, foreign patients to the emergency room of a large American private hospital. Although the hospital is legally bound to care for these patients, providing long term, high cost care for them and others soon becomes a major financial strain.

Intracranial Pressure is a linking keyword, uniting various aspects of diagnostics and treatment of hydrocephalus, head injury, subarachnoid haemorrhage, and brain ischaemia. This volume contains selected papers presented at the XIth International Symposium on Intracranial Pressure and Brain Biochemical Monitoring, held in Cambridge, UK, in July 2000. Various clinical and experimental methodologies are discussed including multiparameter brain biochemical monitoring (including brain oxygenation, microdialysis and novel imaging techniques), assessment of cerebral autoregulation, measurement of brain compliance, etc. This state-of-the-art volume introduces neuroscientists into a world of new techniques, models, monitoring modalities but also theories and new concepts, which highlight directions for the further research and future clinical practice.
