This book covers the gamut of emergency medicine practice in brief, clinically focused chapters. New to this edition are chapters on bioterroism and weapons of mass destruction, pharmacology of antimicrobials, antifungals, and antivirals, principles of drug interactions, endocarditis, and abdominal and pelvic pain in the non-pregnant patient. Pharmacologic considerations, tables of vital differential diagnoses, and observation criteria throughout are new features reflecting developments in this dynamic specialty.
