In concert with an evolution toward an increased awareness of the need to tightly manage temperature, the methods used to monitor and manipulate temperature have evolved from mercury-filled glass thermometers, alcohol baths, and ice packs into a high technology-driven multidisciplinary activity. The purpose of this article is to provide a brief overview of the historical development of temperature management and the primary tenets of each of the 3 phases (induction, maintenance, and rewarming), which are now recognized as crucial steps to ensure the safe practice of therapeutic temperature management.
