In severe hypothermia, which warming method is preferred for rapid rewarming?

• A. Passive external warming
• B. Pharmacologic warming
• C. Ambient warming with blankets
• D. Rapid active warming with circulating 37-40°C water

Answer: (D)

In severe hypothermia, restoring core temperature quickly is the priority because organs and the heart are at risk when the body is that cold. Passive warming or just piling on blankets can slow the process and leave the core temperature dangerously low for longer. The most effective way to rewarm rapidly is an active method that directly heats the body's core: circulating warm water at about normal body temperature (37–40°C). Water transfers heat very efficiently, and circulating systems deliver a controlled, even amount of heat to the patient, warming from the core outward much faster than blankets or ambient warmth. Pharmacologic warming doesn’t provide a real source of heat and can’t reliably raise the core temperature quickly enough in severe cases. So rapid active warming with circulating warm water is the preferred approach for fast rewarming in severe hypothermia.
