When experiencing medical problems in the wilderness, the dictum "Don't do any harm until the doctor comes" is not adequate because in many cases the doctor is not coming and mere first aid becomes insufficient for addressing problems. This work, edited by Wilkerson (chairman, Continuing Medical Education Committee, Wilderness Medical society), Moore (director, Rocky Mountain Regional Trauma Center, Denver Health Medical Center), and Zafren (medical director, Alaska Mountain Rescue Group), is thus a handbook of medicine, not first aid, for the prevention, diagnosis, and treatment of traumas and diseases that may be encountered during wilderness expeditions. Thirty-three chapters (expanded from the last edition's 25) are organized into sections covering general principles, traumatic disorders, nontraumatic disorders, and environmental injuries.
