A reliable rapid-access guide to assessing and treating poisoned patients. Designed and organized for quick consultation and focused on practical clinical issues, the reference covers the full range of chemicals, medications, natural compounds, adverse interactions, and patient presentations with toxicologic causes. Each topic is divided into standard categories: Basics, Diagnosis, Signs/Symptoms, Treatment, Follow-up, and Pitfalls. An entire section is devoted to evaluating patients with suspected but unidentified poisoning. At least two experienced, board-certified, practicing emergency physicians and toxicologists were involved in the editing of every section.
