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.

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.

Albumin is the most abundant serum protein produced by the liver. In clinical practice the serum level of albumin continues to be used as an important marker of the presence, progress or ofthe improvement of many diseases, even though it is the complex end result of synthesis, degradation a. nd distribution between intra- and extravascular space. The clinical history of albumin began as early as in 1837, when Ancell first recognized "albumen" and noted that this protein is needed for trans port functions, for maintaining fluidity of the vascular system and for the prevention of edema. However, the important physiological properties of serum proteins and their role in the regulation ofthe oncotic pressure were demonstrated later by the physiologist E. H. Starling in 1895. In 1917 the clinician A. A. Epstein first described the edema in patients with the nephro tic syndrome as being a result of a very low level of serum albumin. Al though the determination of serum albumin concentration became more popular after Howe in 1921 introduced the technique of separation of serum globulins from albumin by sodium sulfate, the first preparations of human serum albumin were made available for clinical use in only 1941 by the development of plasma fractionation by Cohn and his coworkers at Harvard Medical School."

From the viewpoint of a health economist, the intensive care unit (leU) is a particularly fascinating phenomenon. It is the epitome of "high-tech" medicine and frequently portrayed as the place where life-saving miracles are routinely wrought. But the popular imagina tion is also caught up in the darker side, when agonizing decisions have to be made to avoid futile and inhuman continuation of expen sive treatments. My analytical interests led me to approach these issues by asking what the evidence tells us about which leu activities are very bene ficial in relationship to their costs and which are not. This quickly translates into a slightly different question, namely, which patients are most appropriately treated in an leu and which not. Unfor tunately, it is very hard to answer these questions because it has pro ved very difficult to investigate these issues in the manner which is now regarded as the "gold standard: ' namely by conducting rando mized clinical trials or alternative courses of action. I think this is a pity, and I am not at all convinced that it would be unethical to do so in many cases, because there is wide variation in practice and ge nuine doubt as to which practices are best -the two conditions that need to be fulfilled before such a trial is justifiable."

After a long period of neglect, the gastrointestinal tract is increasingly being recog nized as an important target of anesthetics and anesthesia-related processes, as well as of conditions and treatments related to peri- and postoperative period and inten sive care. Drugs used in anesthesia and intensive care and physiological or pathologi cal changes in the perioperative period affect the digestive system in its function from the pharynx to the colon. Prolonged postoperative ileus or stasis of propulsive peri stalsis in the critically ill or multiply injured patient may impair enteral nutrition and give rise to complications such as sepsis or multiple organ failure. In view of this new understanding of the clinical relevance of gut function, we felt that a book on problems of the gastrointestinal tract in anesthesia, the perioperative period, and intensive care was badly needed. The present volume is the product of an international symposium which brought together physiologists, pharmacologists, experimental and clinical anesthetists, gastroenterologists, surgeons, and intensive care physicians to discuss all major contemporary aspects of bowel function in health and under the influence of anesthesia, surgery, and intensive care."

A concise yet complete overview of the treatment of cardiovascular instability in the critically ill patient. The authors consider all aspects, ranging from basic physiology and pathophysiology to diagnostic tools and established and novel forms of therapy. The whole is rounded off with an integration of these principles into a series of clinically relevant scenarios.

The manuscripts in this book were generated from a conference occurring at the University of Heidelberg in September 1996. These manuscripts have been reviewed and updated by the designated authors in late 1997 for publication in early 1998. Conferences occur for a variety of reasons. These include the need to exchange information where complex activities are undergoing reassessment or change. For the emergency and critical care man agement of stroke this is certainly the situation. Today, both the pri mary care and the neurologic physician must provide medical care in an environment where daily change in the knowledge base of: brain function, disease mechanism(s), therapeutic efficacy, and cost control are all occurring. In addition, patient advocacy has become increasingly complex because government, employers, insurers, health care providers as well as families all desire a voice in the phy sician relationship with the patient. Our conference subject was the organization of rapid care delivery and the development of a ration al basis for treatment of a previously untreatable disorder acute stroke. Thus, the obvious need for multiple open and free discus sions about priority setting and modification of current treatment plans. Clearly, the face to face opportunities provided by this first conference on Emergency Management And Critical Care Of Stroke (EMACCOS) are required when patient care issues are as complex as these. Neuroscience is new to the experience of active therapeutic inter vention.

To be asked to prepare a second edition of a book is heartening for any author or editor. Apart from the opportunity to make the corrections and amendments which are inevitable in a practical manual there is also the possibility to make additions which enhance its usefulness. Above all a further edition usually means that the book has been found to be accept able to a large number of readers and has fulfilled a need. This is indeed the case with Offshore Medicine, which in its description of the medical aspects of offshore work has provided a unique guide to the occupational health of a new industry. The rapid development of offshore exploration for gas and oil which began in the 1960s created a whole new range of related industries. Most attention was focused on the problems of deep diving in the North Sea because of the great expansion of the diving industry, its technological advances and the high mortality of divers in the early years. Diving, however, is only a fraction of the total endeavour concerned with the offshore industry. The much larger population of workers offshore who man the rigs and barges, the toolpushers, helicop ter pilots, crane drivers, scaffolders and roustabouts, geologists and so on, so sympathetically described by A. Alvarez in his recent book Off shore, A North Sea Journey, and the harsh and difficult conditions in which they often have to work are sometimes forgotten."

There is a tendency of an increasing number of signals and derived variables to be incorporated in the monitoring of patients during anesthesia and in intensive care units. The addition of new signals hardly ever leads to thedeletion of other signals. This is probably based on a feeling of insecurity. We must realize that each new signal that is being monitored brings along its cost, in terms of risk to the patient, investment and time. It is therefore essential to assess the relative contribution of this new signal to the quality of the monitoring process; i. e. given the set of signals already in use, what is the improvement when a new signal is added? Beyond a certain point the addition of new information leads to new uncertainty and degrades the result (Ream, 1981) In the diagnostic process, it is possible to evaluate "result" in an objective, qualitative way. The changes in the sensitivity and specificity of the diagnosis as a result of the addition or deletion of a certain variable can be calculated on the basis of false negative, false positive, correct negative and false negative scores. Different methods for multiple regression analysis have been implemented on computers (Gelsema, 1981) which can support such decision processes. In monitoring, the situation is much more complex. Many definitions of monitoring have been given; the common denominator is that monitoring is a continuous diagnostic process based upon a (semi)continuous flow of information. This makes simple assessment methods useless.

Modern critical care is characterized by the collection of large volumes of data and the making of urgent patient care decisions. The two do not necessarily go together easily. For many years the hope has been that ICU data management systems could play a meaningful role in ICU decision support. These hopes now have a basis in fact, and this book details the history, methodology, current status, and future prospects for critical care decision support systems. By focusing on real and operational systems, the book demonstrates the importance of integrating data from diverse clinical data sources; the keys to implementing clinically usable systems; the pitfalls to avoid in implementation; and the development of effective evaluation methods.

The science of neuroanaesthesia and neurointensive care is fascinating, and the amounts of experimental and clinical studies are overwhelming. Surely, everyone can surf Medline and other database systems in order to get information. If you, however, ask for head injury, cerebral ischaemia or barbiturate, you will get hun dreds, may be thousands of titles and even the same number of abstracts. The aims of this book are to review important experimental and clinical data with emphasis on up-dated references. The text within each issue and sub-issue systematically covers experimental and clinical data separately, and details con cerning cerebral blood flow, cerebral metabolism, intracranial pressure etc. are reviewed accordingly. In our survey of the literature we did not use Medline or other database sys tems systematically. Rather, we used available medical journals which covered the topics of anaesthesia, neuroanaesthesia and neurointensive care. In this way we hope that relevant literature is presented. On the other hand, we cannot exclude that some important issues are omitted. The book covers 12 topics. In three chapters methodology of CBF measure ments, regulation of CBF, and intracranial pressure are described. In the next 6 chapters inhalation anaesthetics, hypnotic agents, analgesics, muscular relaxants, drugs used for control of blood pressure, and the sitting position are reviewed. The last three chapters cover head injury, subarachnoid haemorrhage and cere bral ischaemia."

Synthesizing insights from psychiatry, social psychology, and anthropology, this important work sets out a framework for therapy that is as culturally informed as it is productive. An international panel of 23 therapists offers contextual knowledge on PTSD, coping skills, and other sequelae experienced by the survivors of traumatic events. Case studies from Egypt to Chechnya demonstrate various therapeutic approaches. Authors explore the balance of inter- and intrapersonal factors in reactions to trauma and dispel misconceptions that hinder progress in treatment.

Severe head injuries are a frequent occurrence in the life of every emergency care specialist, traumatologist, neurosurgeon, and rehabilitation specialist. For example, between 30.000 to 40.000 severe head injuries occur in Germany each year. Over 75.000 Americans die each year after having suffered a severe head injury. Nevertheless, treatment is not always optimal. Survival and longterm outcome depends not only on the type of injury but also on timely and appropriate diagnosis and treatment. Thus, all physicians involved must be aware of the current procedures in the management of severe head injuries. This reference book, based on the experience of international experts, provides an up to date and practical guideline.

Serious disturbances of fluid and electrolyte balance are frequently encountered in acutely ill patients; somewhat less often in the chronically sick. There seems to be a trend for such cases to increase, due probably to an increase in major surgical procedures on older patients whose renal function is less than adequate. There are already many publications dealing with the physiology of the homeo stasis of fluid and electrolytes, and others dealing with the clinical aspects of the subject. It is often assumed that a knowledge of the basic principles of physiology will enable the doctor to prescribe suitable intravenous therapy. In practice this is often found not to be so and the evidence for this is the frequency of calls for help with electrolyte problems from well-qualified and experienced doctors who are undoubtedly equipped with adequate or even excellent knowledge of the basic It is not an unusual observation that knowledge of theory and principles involved. principles does not necessarily lead to successful practice in this or any other art or craft. Most doctors already possess knowledge of the physiology of the internal envi ronment, but some are aware of being unable to deal effectively with clinical problems related to fluid and electrolyte disturbances and seek guidance to translate theoretical knowledge into practice."

Provision of efficient resuscitation is mandatory to the success ful functioning of all hospital wards and departments. Failure to provide such a service increases morbidity and mortality. Resuscita tion falls largely into the domain of the anaesthetist. However, an anaesthetist is not always instantly available and resuscitation has to be initiated by those in other specialities who have had little or no for mal training in resuscitation techniques. The purpose of this book is to guide those involved in resuscitation in the indications and methods of resuscitation. Its creation and con tents were stimulated by noting the difficulties encountered in both teaching centres and provincial hospitals. 'Basic' is included in the title to emphasize that, with the exception of 'the acid-base laboratory', the apparatus is simple and available in all hospitals. Furthermore, 'basic' indicates the authors' intention to limit their discussion on resuscitation to that involved in the first hour following the start of treatment. Successful treatment during these 60 minutes, and very often the first few minutes, is often vital in the sav ing of life. Further management can then be decided by the ap propriate specialist.

A comprehensive text of intensive care would readily fill the equivalent of the Shorter Oxford English Dictionary. This is because the diseases treated are both numerous and varied; thus the patient can be medical, surgical, trauma or obstetric. It follows that the sum total of knowledge which needs to be available is truly encyclopaedic. This compact volume represents only a fragment of such information. The contributors were chosen because of their experience and because their methods were well-tried. The text therefore summarizes the best of current therapy and includes the controversial. The contributors come from four countries, adding an international flavour. One topic - The Recovery Room - outside the confines of intensive care has been included for two reasons. The recovery room is an important but neglected aspect of care, and it also seems important to define its relationships with the intensive care unit. It is hoped that the book will help the nurses and doctors involved in intensive care and, therefore, the patient. ERIC SHERWOOD JONES Vll Contributors P. M. ASHWORTH K.

Intensive Care Medicine has been continuously growing and expanding, culturally, technically and geographically. Monitoring and instrumentation are continuously improving and more and more hospitals are getting Intensive Care facilities. The costs have proportionally increased over the years, so that ICUs represent today a major cost for health structures. Since the available resources are limited, a real need is emerging to set the limits and indications of Intensive Care. It is understood that the problem not only involves medical considerations, but also ethical and economical aspects of the utmost importance. For the first time in Europe, this book edited by Reis Miranda and his colleagues tackles systematically the many structural aspects of the European Intensive Care. The organisation and financing of health care in the Old Continent is deeply different from the American one, and the results and consequent proposals obtained in the USA cannot simply be transferred to this side of the Atlantic Ocean. Weare extremely pleased to welcome this first European attempt to discuss the Intensive Care problem. It lays no claims to giving definite replies in a continuously developing field, but it will surely become the basis for future discussions and proposals. I am particularly happy that this work has mainly developed within the European Society of Intensive Care, whose final target is to ensure a common standard of therapy in our old Europe, beyond national differences. We warmly congratulate the authors, and I am sure that their work will find wide diffusion and consent.

This volume is published with a triple aim: to take a look back over the advances during the ten years of the Mediterranean Burns Club and mark its anniversary; to follow up and strengthen the successful twin ning of burns as a clinical, individual illness problem and fires as a societal, disaster management problem; and to look ahead at the per spectives of burn care and fire prevention in the fast-approaching new century. The occasion also marks the tenth annual presentation of the prestigious G. Whitaker International Burns Prize, to which the Mediterranean Burns Club acts as the scientific fulcrum. The award is now established as the most distinguished recognition in burns science worldwide, and it is gratifying that the contributions of many of the renowned recipients will be found in this book. This is a sequel to The Management of Mass Burn Casualties and Fire Disasters, which contained the Proceedings of the First International Conference on Burns and Fire Disasters. The book and the conference have fully justified the authors' initial concept that burn specialists, con stantly combatting burn disease and promoting rehabilitation of the victims, especially in mass casualty situations, had for too long remained separate from that other essential sector, the fire-fighting authorities and fire prevention systems, whose aim is also the protection of the individual and the promotion of safety. This long overdue synergism has now become reality, and the present volume strengthens this desirable trend."

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.

Dr. G. M. Woerlee is well known in my department both as a clinician and teacher. Years ofexperience have taught him that the problems discussed here have as yet not been treated in this way in any single work. In my opinion there is a real need for such abook, not only for resident and specialist anaesthetists, but also among surgeons and internists, specialist and trainee. Management of a patient in the operating room is a matter of teamwork, and knowledge of the problems encountered is the basis of any mutual understanding The information which has been assembled and clearly presented in this book should prove to be of great assistance in guiding our patients though an important phase of their lives. Professor Dr. Joh. Spierdijk, Department of Anaesthesia, University Hospital of Leyden, The Netherlands. vii PREFACE Much of the literature being published in the field of anesthesiology today concerns a narrow, in-depth scrutiny of a specific area or anesthetic technique that does not provide the novice with an overview ofthe perioperativeperiod and the commoneveryday problems faced by the anesthetist. Dr G. M. Woerlee of the University of Leiden with his book, "Com mon Perioperative Problems and the Anaesthetist," has filled a void in the current anes thetic literature. Dr Woerlee reviews in a straightforward, no-frills manner problems routinely encountered during the perioperative period. Other anesthesia textbooks do not cover the material in quite the same logical, step-by-step fashion."

Substantialfundamental workhas been undertaken inthe different aspects of impact biomechanics over the past three decades. Much of this has been motivated and undertaken bythe automotive industry intheirefforts to improve transport safety. More recently, however, it has become app- ent that themultidisciplinary synergies which are realisedby interactions between engineers, scientists and clinical practitioners will ultimately lead to a greater understanding of the complex interacting phenomena withinthe human bodyafter it has sustained an impact. In turn, this greater depth of knowledge will provide more fundamentalinsights into the analysis, d- gnosis, treatment and prevention ofimpact injuries across a broader sp- trum of accident environments. Thescienti?c focus of this IUTAM symposium istoaddress those t- ics that are centrally important to the biomechanics ofimpact. These can be groupedinto those that are concerned with the different causes of - cidents (e. g. , transport, occupational and sports injuries), themechanics - volvedinaccident analysis (e. g. , accident investigation, computational m- elling techniques), the different types of resulting traumatic injuries (incl- ing musculoskeletal, organ, spinal and head injuries), methods of asse- ing the extent of injury (e. g. , injury assessment, injury criteria, constitutive laws for human tissue), and providing protection during an impact (e. g. , injury prevention, energy absorption materials, and safety devices).

PATIENT FLOW: Reducing Delay in Healthcare Delivery is dedicated to improving healthcare through reducing the delays experienced by patients. One aspect of this goal is to improve the flow of patients, so that they do not experience unnecessary waits as they flow through a healthcare system. Another aspect is ensuring that services are closely synchronized with patterns of patient demand. Still another aspect is ensuring that ancillary services, such as housekeeping and transportation, are fully coordinate with direct patient care. Past experience shows that effective management of healthcare delays can produce dramatic improvements in medical outcomes, patient satisfaction, and access to service, while also reducing the cost of healthcare. The 15 chapters of this book exposes the healthcare community of researchers, practitioners and administrators to a set of techniques and strategies that can be used by clinicians and administrators to substantially reduce delays in healthcare delivery. It is the first book treatment to have reduction in patient delay as its sole focus, and therefore, provides the foundation by which hospitals can implement change. Reflecting the highly interdisciplinary and practitioner nature of this book, the chapters have been written by doctors, nurses, industrial engineers, system engineers and geographers, and thus, these perspectives provide the comprehensive view needed to address the problem of patient delay.

The book provides a "hands-on" discussion and methods for solving a variety of problems that inhibit prompt and swift health care delivery. Some examples are:

• presents a set of breakthrough strategies that use "real-time" monitoring systems for continuous improvement;
• offers techniques for scheduling staff needs to match patterns in patient demand, and thus reduce predictable delays;
• utilizes simulation modeling techniques for both healthcare design and process improvement;
• provides methods for forecasting the demand for healthcare on a region-wide basis;
• presents queueing theory as a general method for modeling patient waits in healthcare;
• outlines rapid delivery of medication in the event of a catastrophic event, such as a pandemic or terrorist attack;
• demonstrates the importance of optimizing care as patients transition from one care setting to the next care setting with an emphasis on clinical outcomes and the business case;
• provides project management tools to guide the implementation of patient flow projects.

lnflammatory reactions are generated in response to extemal and intemal stimuli, such as infection, trauma, clinical insult or dysregulation of the umnune system. The int1ammatory responses may bc antigen-specific or non-specific, local or systemic, chronic or rapid and severe, characterized by a massive release of mediators, often lethal. The aim of this book is to review selectcd aspects associated with the mechanism of the pathology of int1ammatory processes of ditlerent origin and to evaluate therapeutic strategies aimed at combating various inflamma- tory diseases. The introductory article describcs the inmlllnological status of patients with severe sepsis, with particular attention paid to the roJe of circulating neutrophils. Intcgrin activation and chemokine receptor expression and the roles of IL-15, prostaglandins and leukotriens in inflmmnation and immunity are the subjects of next articles. Subsequent reviews are focused on allergic diseases involving mast cells and Th2 type cytokines, in particular the mech- anisms of atopic dennatitis and signaling hy IL-13. The intlmmnatory responscs elicited by Mycobacterium tuberculosis and Mvcobacferium nviwn are also analyzed with special interest paid to the mechanisms which allow the bacteria to escape the host' s immune reactions. The thcrapeutic potential of IL- I 0 in infection and inflammation and thc possible factors contributing to the devclopment of idiopathic pulmonary fibrosis are rcvicwed in the next articles. The final report demonstrates the advantages of bacteriophage ther- apy in thc context of the aggravating problem of hactcrial resistance to antibi- otics.

Therapeutic Hypothermia will provide a review of the subject, in particular, resuscitative hypothermia and include known mechanisms of action and results from both mechanistic and outcome laboratory studies and clinical trials. Cooling methods and potential side effects of hypothermia will be addressed as well as recommendations for future laboratory and clinical research.

This volume will be of interest to both the researcher interested in therapeutic hypothermia as well as the clinician interested in the potential use of therapeutic hypothermia in their patient population.
