Which option best describes preventing hypothermia during anesthesia?

• A. Keep room at normal temperature
• B. Provide warmed blankets
• C. Keep patient cool with fans
• D. Use warming blankets

Answer: (D)

Active warming with warming blankets is the most effective way to maintain normal body temperature during anesthesia. When anesthesia starts, the body’s natural heat-regulation mechanisms are blunted, and the operating room is often cool, so the patient loses heat quickly through radiation, convection, and evaporation. Using warming blankets delivers controlled heat to a large surface area, helping to maintain a stable core temperature and reduce the risk of hypothermia and its complications, such as increased blood loss, infection risk, and cardiovascular stress. Merely keeping the room warm or using passive warmed blankets provides some warmth but isn’t as reliable as active warming. Using fans to cool the patient would worsen heat loss. So, warming blankets offer the best, proactive protection against hypothermia during anesthesia.
