Presents evidence-based national guidelines and treatment algorithms for managing pain in patients in the critical care, trauma, and emergency room settings. Such patients often present with co-morbid and complex conditions which often make accurate pain assessment and treatment a challenge. In an easy-to-use, bulleted format, the book provides the most current information on assessing and managing pain in a variety of critical conditions. Both pharmacological management therapies and non-pharmacologic interventions are included along with information about pain assessment screening tools for special populations. Topics covered include the basics of pain physiology in critical, emergency, and operative care patients, assessing pain in the critically ill, medications and advanced pain management techniques useful with this population, and commonly occurring conditions in the various care environments. Also addressed are the management of particularly challenging patients (elderly, obese) and conditions (chronic pain, renal failure, chemically dependent patients, and burn patients). The book contains tables that efficiently summarize information and figures to illustrate key concepts.
