This second edition offers a revision of the original text. While keeping the regional chapter organization, the content of the text has been brought up-to-date to reflect current concepts and treatment modalities. The text has been expanded to cover a broader scope of clinical practice and to provide greater depth of coverage of specific subject areas. It is designed to serve as a definitive reference for most practitioners. At the same time, its regional organization, format and manageable size make it a handy ready reference for the office of an emergency room.
