Question

Quizplus · Accepted Answer

Active rewarming involves applying an external source of heat, such as warm blankets, heating pads or warm fluid infusions, to the patient's body to raise his core temperature. This method is effective and recommended for patients with mild to moderate hypothermia. Peripheral rewarming, on the other hand, involves warming only the limbs and extremities and is not recommended for patients with severe hypothermia. Central rewarming involves applying heat directly to the core of the body, such as through warm intravenous fluids or a warming catheter, and is typically reserved for severe cases of hypothermia. Endogenous rewarming refers to the body's natural processes for increasing core temperature, such as shivering or metabolic processes, but is not a reliable method for treating hypothermia.
