Neurologic consultations are essential to patient outcomes, not only providing diagnostic, therapeutic, and prognostic advice but also directing care to the patient. Neurologic Complications of Critical Illness is the foremost guide for neurologists entering the intensive care unit (ICU). This fourth edition has been thoroughly updated, refreshed, and expanded in recognition of the vast number of changes in neurology and neurocritical care. In addition, every chapter provides a representative selection of the state-of-the art management and latest clinical innovations in critical care medicine. As with previous editions, the book offers practical advice on dealing with coma and outcome after cardiopulmonary resuscitation (CPR), failure to awaken after surgery, delirium, new onset seizures, generalized weakness, acute paraplegia, movement disorders and many other manifestations of a neurologic emergency such as complications after organ transplantation, neurologic complications of invasive procedures and devices, complications from cardiac surgery, traumatic brain, spine and peripheral nerve injury, and environmental injuries such as hypothermia and near drowning. Chapters include a wealth of helpful tables, precise algorithms, and a large, curated selection of neuroimaging. Each chapter has a section to reconcile theory and practice. This edition offers new chapters on the interpretation of focal findings and acute movement disorders in critical illness, cancer immunotherapy and ethical dilemmas. This clinical text with dedicated coverage of all major neurologic illnesses will be helpful to a very wide audience of health care providers and any intensivist and general neurologist managing complex medical disorders, surgeries, and co-morbidities.
