To help prevent hypothermia, active warming should begin in which area?

• A. In the Operating Room
• B. In the Recovery Room
• C. In the Preoperative Holding Area
• D. Just before the incision

Answer: (C)

Starting active warming in the preoperative holding area is most effective because it builds a thermal reserve before anesthesia begins. Anesthesia stops the body's normal thermoregulatory responses and causes vasodilation, allowing heat to move from the core to the periphery quickly. If warming starts only after entering the OR or just before incision, much of the heat loss has already occurred, which can lead to intraoperative hypothermia and associated risks like shivering, increased cardiac stress, and wound complications. Warming in the holding area allows you to keep the core temperature closer to normal by preemptively reducing the temperature gradient before exposure to the cold operating room environment. A typical goal is to pre-warm for 15–30 minutes with a warming device when feasible. Warming in the recovery room is important for ongoing comfort and preventing postoperative hypothermia, but it does not prevent the intraoperative temperature drop as effectively as pre-warming in the holding area.
