Available in PDF, EPUB and Kindle. Book excerpt: General anesthesia is a standard medical procedure in today's hospital practice. Although in most cases the administration of anesthetics does not affect severely the patients health, side effects of anesthesia are well-known, such as nausea or cognitive impairment. Moreover 1-2 out of 1000 patients under surgery report a partial wake up from anesthesia during the operation. The reason for such a partial lack of control of depth of anesthesia is that medical procedures are highly optimized based on experience but the neural dynamics during general anesthesia is far from being understood. One reason for this lack of understanding is both the complex neural interactions of neurons on different spatial and temporal scales and the poorly understood action of anesthetics on neural populations. For instance, anesthetic agents act on synaptic receptors on a microscopic scale essentially evoking a macroscopic change of population activity, such as Local Field Potentials, EEG/MEG or resulting change of cerebral blood flow. This population effect then triggers the loss of consciousness in patients. This Research Topic aims to address recent theoretical and experimental advances in the field. The theoretical and experimental studies represent a good overview over the current state of research in the field and provides a deeper insight into the underlying neural mechanisms. Each article in the issue focusses on a specific current research topic in general anesthesia research and several articles introduce to the topic in a pedagogical way. The issue covers various types of anaesthesia and the most important topics in the field, such as (but not limited to) recent advances in theoretical models and states of consciousness reflected in experimental data, the connectivity changes observed during anesthesia or effects of specific drugs on brain activity. The introduction style of the papers facilitates the reader to understand the background of the research aspect and even allows readers not familiar with general anesthesia research to enter the research domain. Hence the Research Topic aims to provide on one hand an overview of the current state of the art and on the other hand a good starting point for new researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Sleep and anesthesia resemble in many ways at a first glance. The most prominent common feature of course is the loss of consciousness, i.e. the loss of awareness of external stimuli. However a closer look at the loss of consciousness reveals already a difference between sleep and anesthesia: anesthesia is induced by an anesthetic drug whereas we may fall asleep without external cause. Other questions may arise about the difference of the two effects: do we dream during surgery under anesthesia, do we feel pain during sleep? Essentially, we may ask: what is common and what are the differences between sleep and anesthesia? To answer these questions, we may take a look at the neural origin of both effects and the involved physiological pathways. In which way do they resemble? Moreover, we ask what are the detailed features of normal sleep and general anesthesia as applied during surgery and which features exist in both phenomena? If yes in which way? To receive answers to these questions, it is necessary to consider several experimental techniques that reveal underlying neural mechanisms of sleep and anesthesia. Moreover, theoretical models of neural activity may model both phenomena and comes up with predictions or even theories on the underlying mechanisms. Such models may attack several different description levels, from the microscopic level of single neurons to the macroscopic level of neural populations. Such models may give deeper insight into the phenomena if their assumptions are based on experimental findings and their predictions can be compared to experimental results. This comparison step is essential for valuable theoretical models. The book is motivated by two successful workshops on anesthesia and sleep organized during the Computational Neuroscience Conferences in Toronto in 2007 and in Berlin 2009. It aims to cover all the previous aspects with a focus on the link to experimental findings. It elucidates important issues in theoretical models that at the same time reflect some current major research interests. Moreover it considers some diverse issues which are very important to get an overview of the fields. For instance, the book discusses not only neural activity in the brain but also the effects of general anesthesia on the cardio-vascular system and the spinal cord in the context of analgesia. In addition, it considers different experimental techniques on various spatial scales, such as fMRI and EEG-experiments on the macroscopic scale and single neuron and LFP-measurements on the microscopic scale. In total all book chapters reveal aspects of the neural correlates of sleep and anesthesia motivated by experimental data. This focus on the neural mechanism in the light of experimental data is the common feature of the topics and the chapters. In addition, the book aims to clarify the shared physiological mechanisms of both phenomena, but also reveal their physiological differences.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years our understanding of molecular mechanisms of drug action and interindividual variability in drug response has grown enormously. Meanwhile, the practice of anesthesiology has expanded to the preoperative environment and numerous locations outside the OR. Anesthetic Pharmacology: Basic Principles and Clinical Practice, 2nd edition, is an outstanding therapeutic resource in anesthesia and critical care: Section 1 introduces the principles of drug action, Section 2 presents the molecular, cellular and integrated physiology of the target organ/functional system and Section 3 reviews the pharmacology and toxicology of anesthetic drugs. The new Section 4, Therapeutics of Clinical Practice, provides integrated and comparative pharmacology and the practical application of drugs in daily clinical practice. Edited by three highly acclaimed academic anesthetic pharmacologists, with contributions from an international team of experts, and illustrated in full colour, this is a sophisticated, user-friendly resource for all practitioners providing care in the perioperative period.

Available in PDF, EPUB and Kindle. Book excerpt: Some important constraints of anesthesia must be taken into consideration when the pharmacological properties of modern anesthetics are discussed. The most imp- tant of these could be that the target effect be achieved preferably within seconds, at most within a few minutes. Similarly, offset of drug action should be achieved within minutes rather hours. The target effects, such as unconsciousness, are pot- tially life-threatening, as are the side effects of modern anesthetics, such as respi- tory and cardiovascular depression. Finally, the patient’s purposeful responses are not available to guide drug dosage, because, either the patient is unconscious, or more problematically, the patient is aware but unable to communicate pain because of neuromuscular blockade. These constraints were already recognised 35 years ago, when in 1972 Volume XXX entitled “Modern Inhalation Anesthetics” appeared in this Handbook Series. The present volume is meant as a follow up and extension of that volume. At the beginning of the 1970’s anesthesia was commonly delivered by inhalation, with only very few exceptions. The clinical understanding of that time considered anesthesia as a unique state achieved by any of the inhalation anesthetics, in- pendent of their specific molecular structure. “The very mechanism of anesthetic action at the biophase” was discussed within the theoretical framework of the “u- tary theory of narcosis”.

Book excerpt: “An engaging and illuminating exploration of the invisible medical specialty that is anesthesia.… Counting Backwards pulls back the veil on the very act of being alive.” —Danielle Ofri, MD, PhD, author of What Patients Say, What Doctors Hear For many of the 40 million Americans who undergo it each year, anesthesia is the source of great fear and fascination. In Counting Backwards, pediatric anesthesiologist Dr. Henry Jay Przybylo delivers an unforgettable account of the procedure’s daily dramas and fundamental mysteries. Przybylo has administered anesthesia more than 30,000 times over his thirty-year career: on newborn babies, screaming toddlers, sullen teenagers, even a gorilla. Filled with intense moments of near-disaster, life-saving successes, and simple grace, Counting Backwards is for anyone curious about what happens after we lose consciousness.

Available in PDF, EPUB and Kindle. Book excerpt: Synthesis of Essential Drugs describes methods of synthesis, activity and implementation of diversity of all drug types and classes. With over 2300 references, mainly patent, for the methods of synthesis for over 700 drugs, along with the most widespread synonyms for these drugs, this book fills the gap that exists in the literature of drug synthesis. It provides the kind of information that will be of interest to those who work, or plan to begin work, in the areas of biologically active compounds and the synthesis of medicinal drugs. This book presents the synthesis of various groups of drugs in an order similar to that traditionally presented in a pharmacology curriculum. This was done with a very specific goal in mind – to harmonize the chemical aspects with the pharmacology curriculum in a manner useful to chemists. Practically every chapter begins with an accepted brief definition and description of a particular group of drugs, proposes their classification, and briefly explains the present model of their action. This is followed by a detailed discussion of methods for their synthesis. Of the thousands of drugs existing on the pharmaceutical market, the book mainly covers generic drugs that are included in the WHO’s Essential List of Drugs. For practically all of the 700+ drugs described in the book, references (around 2350) to the methods of their synthesis are given along with the most widespread synonyms. Synthesis of Essential Drugs is an excellent handbook for chemists, biochemists, medicinal chemists, pharmacists, pharmacologists, scientists, professionals, students, university libraries, researchers, medical doctors and students, and professionals working in medicinal chemistry. * Provides a brief description of methods of synthesis, activity and implementation of all drug types* Includes synonyms* Includes over 2300 references

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the developments and improvements in electroencephalography (EEG). In recent years, digital technology has replaced analog equipments, and it is now possible to easily record and store EEG tracings and to quickly recall previously acquired material for subsequent analysis. In addition, not only static figures, but also electronic supplementary materials can be included in books, enabling EEGs to be viewed in real-time. In clinical practice, EEG still represents the most important functional examination in the study CNS development and its anatomical and physiological integrity throughout life. In the pathological context, EEG provides indispensable diagnostic information for classification of epileptic syndromes, and it is also valuable in all the other CNS diseases (infectious, cerebrovascular, neurodegenerative, etc). Furthermore, monitoring EEG can be widely used in emergency settings, such as emergency departments or intensive care units. In comatose patients, EEG provides information regarding prognosis and evaluation of the sedative effect of anesthetic drugs. Written by a group of leading national and international experts, it offers a substantial, yet practical, EEG compendium, which serves as a reference resource for physicians and neurodiagnostic technologists as well as physicians-in-training, researchers, practicing electroencephalographers and students.

Book excerpt: The problem of how the brain produces consciousness, subjectivity and 'something it is like to be' remains one of the greatest challenges to a complete science of the natural world. While various scientists and philosophers approach the problem from their own unique perspectives and in the terms of their own respective fields, Biophysics of Consciousness: A Foundational Approach attempts a consilience across disparate disciplines to explain how it is possible that an objective brain produces subjective experience.This volume unites the crème de la crème of physicists, neuroscientists, and psychiatrists in the attempt to understand consciousness through a foundational approach encompassing ontological, evolutionary, neurobiological, and Freudian interpretations with the focus on conscious phenomena occurring in the brain. By integrating the perspectives of these diverse disciplines with the latest research and theories on the biophysics of the brain, the book tries to explain how consciousness can be an adaptive and causal element in the natural world.

Available in PDF, EPUB and Kindle. Book excerpt: Ethical issues facing anesthesiologists are more far-reaching than those involving virtually any other medical specialty. In this clinical ethics textbook, authors from across the USA, Canada and Europe draw on ethical principles and practical knowledge to provide a realistic understanding of ethical anesthetic practice. The result is a compilation of expert opinion and international perspectives from clinical leaders in anesthesiology. Building on real-life, case-based problems, each chapter is clinically focused and addresses both practical and theoretical issues. Topics include general operating room care, pediatric and obstetrical patient care, the intensive care unit, pain practice, research and publication, as well as discussions of lethal injection, disclosure of errors, expert witness testimony, triage in disaster and conflicts of interest with industry. An important reference tool for any anesthesiologist, whether clinical or research-oriented, this book is especially valuable for physicians involved in teaching residents and students about the ethical aspects of anesthesia practice.
