This excellent symposium is organized into five main sections dealing with (1) general physicochemical and physiological considerations of hypothermia, (2) effects of hypothermia on specific systems, (3) myocardial irritability and hypothermia, (4) clinical application of induced hypothermia, and (5) techniques of inducing hypothermia. Each section is written in an authoritative fashion with extensive bibliographies, where applicable. Though this field is relatively young and rapidly changing, this book should be read by all who are interested in the subject. The authors present the material clearly and thoroughly. The reviews and discussions serve to blend the various sections into a more homogeneous mass than is usual in symposiums. This book should be of special interest to anesthesiologists, surgeons, physiologists, and pharmacologists. Various members of other medical specialties would do well to read the sections pertaining to their fields.
