What strategies help prevent hypothermia during trauma care, and why is this important?

• A. Exposing skin to ambient air to check for injuries
• B. Warm blankets, warmed IV fluids, radiant heat, and minimizing exposure; prevents coagulopathy and improves outcomes
• C. Using ice packs to dress wounds
• D. Delay warming until after imaging

Answer: (B)

Preventing hypothermia during trauma care is essential because cold body temperature worsens bleeding and overall outcomes. When the patient becomes hypothermic, enzymatic reactions needed for coagulation slow down and platelets don’t work as well, contributing to ongoing hemorrhage, acidosis, and increased mortality—the so-called lethal triad in trauma. The most effective strategies address heat loss directly: using warm blankets or a radiant heat source to shield the patient from the cold environment, keeping the room warm, and minimizing the time the patient spends exposed. Warming IV fluids and other infused products prevents further cooling from those infusions, and radiant heat or forced-air/systematic warming adds direct heat to the body. By maintaining normothermia, you support coagulation, stabilize metabolism, and improve the chances of a favorable outcome. Exposing skin to ambient air, applying ice packs to wounds, or delaying warming until after imaging all promote heat loss and would worsen hypothermia and its consequences.
