This book was originally designed largely for those who work in remote places associated with an environmental hazard such as heat or cold. Since it has been used for the families left at home it also has general appeal. Basically it is a first-aid book but it is presented so that it provides an understanding of the basic nature of the various emergency situations not only to allow appropriate first-aid to be administered but also to care for the casualty for a time if evacuation from the remote place is delayed or even absent. It also trains the casualty handler to communicate an appreciation of the problem to a remote doctor so that he will be in a position to provide quality advice. The book avoids technical terms and is presented in the simple and yet detailed terms of a series of lectures. Certain important areas are thus repeated for emphasis so that a full understanding of the subject can rapidly and painlessly be acquired. It is based on the lecture material for the course which was originally part of the system for remote personnel operating in the offshore oil and gas industry in the North Sea and which was subsequently found to be equally useful for the personnel of the British Antarctic Survey operating in small parties far from base. The lecture course has also been extensively used by oil company personnel in the Middle East, particularly those who operate in lonely desert areas or offshore. The book is illustrated by clinical pictures and diagrams to show the nature of the injuries and conditions described such as burns, fractures, wounds, bleeding, eye injuries, heat illness, etc. This introduces the trainee to the types of emergency which he may be called upon to manage and helps to determine how best they should be treated in both urban and remote situations. The descriptions of such fundamental areas as the management of unconsciousness, the nature of respiratory and circulatory failure and resuscitation are also fully complimented by diagrams and photographs.
