Graphic Representation of the Typical Triphasic Core Temperature Pattern that Occurs after Induction of Anesthesia Note that the Phase 3 Plateau May Not Occur, Particularly During Regional Anesthesia or During Combined Regional and General Anesthesia. Although Core Temperature is Preserved During the Phase 3 Plateau, Heat Will Continue to Be Lost to the Environment from the Peripheral Compartment.
