Recent advances in medicine for resuscitation and care have led to an increased number of patients that survive severe brain damage but who are poorly responsive and non-communicative at the bedside. This has led to a striking need to better characterize, understand, and manage this population who present a real challenge for the assessment of pain and for planning treatment. This edited collection provides clinicians with a guide to recent developments in research on pain perception and assessment, and the detection of consciousness and communication in patients with disorders of consciousness (DOC). With contributions from leading global researchers, the book gives an overview of issues concerning the assessment of pain. It also covers the development of suitable tools both to improve pain management and to detect consciousness and communication in these patients, to influence their prognosis and treatment, and their quality of life. Methodological and ethical issues concerning the implication for future research are also considered. The book will be an invaluable guide for clinicians, medics and therapists working in rehabilitation and acute care, particularly in the demanding field of pain perception, pain assessment and detection of consciousness and communication in patients with DOC. It will also be useful for students and researchers in neuropsychology and medical sciences.

Highly Commended, BMA Medical Book Awards 2015 In 2008, Paul Farmer and Jim Yong Kim described global surgery as the "neglected stepchild" of healthcare, and now leaders from around the world are working to redefine it as a human right through the Lancet Commission on Global Surgery. In order to help advance global surgery and anesthesia as a public health intervention, providers require a practical, hands-on manual to train and educate them to provide safe and effective surgery and anesthesia in resource-limited settings. In an effort to respond to that need, over 140 clinicians from high-, low-, and middle-income countries collaborated to create the Global Surgery and Anesthesia Manual: Providing Care in Resource-Limited Settings. This guide provides in-depth instruction on epidemiology and ethics surrounding surgical services, and on anesthesia, perioperative care, trauma surgery, and non-trauma surgery. With contributions from a group of culturally and academically diverse clinicians, each chapter is enriched by at least one commentary from a surgeon or anesthesia provider in a low- or middle-income country (LMIC) who shares first-hand perspectives on the realities and complexities of providing surgical care in these settings with limited resources. The book will serve as a core reference for surgeons and anesthesiologists at all levels interested in global surgery. It will assist those working in LMICs who are confronted with surgical problems that they are not routinely exposed to in their traditional practice. Filled with expert guidance, decision-making algorithms, and treatment options, it will also serve as an invaluable text for trainees in LMICs as it covers the majority of surgical disease processes that would be encountered in such settings.

Emergency and critical care providers are often challenged by patients with acute cardiorespiratory symptoms and abnormal electrocardiograms. Critical Cases in Electrocardiography emphasizes clinically-relevant topics, focusing squarely on situations where interpretation of the ECG contributes to clinical decision-making. This atlas is unique, in that it includes numerous examples of ECG 'misses' - cases where the computer algorithm or the clinicians (or both) got the diagnosis wrong. While many textbooks include only smaller, black and white ECG tracings, which do not resemble actual clinical practice, this volume is designed to encourage self-study of the ECG by including full-page tracings in their natural color. The book focuses on 'don't miss' ECG tracings in order to help readers advance beyond the stage of 'competent' electrocardiographer. Anatomic and electrophysiologic correlations are emphasized throughout the work, helping readers appreciate the anatomic and electrical origins of the ECG abnormalities, rather than relying solely on pattern memorization.

Resuscitation is a two-stage process comprising the achievement/maintenance of spontaneous circulation and post- resuscitation management.

For hundreds of years cannabis has been used as a therapeutic medicine around the world. Cannabis was an accepted medicine during the second half of the 19th century, but its use declined because single agent pain medications were advocated by physicians who demanded standardization of medicines. It was not until 1964 when the chemical structure of THC (delta 9-tetrahydrocannabinol) was elucidated and its pharmacological effects began to be understood. Numerous therapeutic effects of cannabis have been reviewed, but cannabis-based medicines are still an enigma because of legal issues. Many patients could benefit from cannabinoids, terpenoids and flavonoids found in Cannabis sativa L. These patients suffer from medical conditions including chronic pain, chronic inflammatory diseases, neurological disorders, and other debilitating illnesses. As more states are legalizing medical cannabis, prescribers need a reliable source which provides clinical information in a succinct format. This book focuses on the science of cannabis as an antioxidant and anti-inflammatory supplement. It discusses cannabis uses in the human body for bone health/osteoporosis; brain injury and trauma; cancer; diabetes; gastrointestinal conditions; mental health disorders; insomnia; pain; anxiety disorders; depression; migraines; eye disorders; and arthritis and inflammation. There is emphasis on using the whole plant - from root to raw leaves and flowers discussing strains, extraction and analysis, and use of cannabis-infused edibles. Features: Provides an understanding of the botanical and biochemistry behind cannabis as well as its use as a dietary supplement. Discusses endocannabinoid system and cannabinoid receptors. Includes information on antioxidant benefits, pain receptors using cannabinoids, and dosage guidelines. Presents research on cannabis treatment plans, drug-cannabis interactions and dosing issues, cannabis vapes, edibles, creams, and suppositories. Multiple appendices including a glossary of cannabis vocabulary, how to use cannabis products, a patient guide and recipes as well as information on cannabis for pets.

The Royal College of Anaesthetists has introduced Constructed Response Questions (CRQs) as an innovative way of testing trainees, in the fields of anaesthesia and intensive care medicine, in their final FRCA examinations from September 2019. CRQs are a more structured way of assessing knowledge and understanding; they also assess the application of knowledge, evaluation and judgement. This book categorises 134 questions based on the Royal College model, with six mandatory sections of training and two separate sections on general duties and optional units. In the FRCA exam, there will be a total of 12 questions, one each from the six mandatory units of training (neuroanaesthesia; obstetric anaesthesia; paediatric anaesthesia; pain; cardiac anaesthesia; and intensive care), and six from general duties which may include one from optional unit training (perioperative medicine; regional, orthopaedic and trauma anaesthesia; other topics in general medicine; and optional topics). The answers have been extensively researched from recent BJA Education papers, e-learning, CEPD resources and other vital educational materials. To make it easy for the revising candidate, the questions have been split into their respective subspecialty topics, so the reader can assess their knowledge appropriately in a timely manner. It is an ideal companion for candidates who are preparing for their final exams in anaesthesia and will help to assess their preparation and guide appropriate revision. The topics are pertinent for other anaesthetic exams worldwide, including the European exams, Australian and New Zealand fellowships and the Indian DNB exams. The authors have extensive experience in anaesthetic teaching and lead anaesthetic intermediate teaching in the UK, running regular and successfully attended courses. This book will help candidates to adapt to the recent exam changes and revise in an efficient manner. It will not only be an invaluable educational resource for trainee anaesthetists but also for practising anaesthetists. Medical students and junior doctors, who are about to embark on a career in anaesthesia or intensive care medicine, will also find the book to be a useful educational tool.
