What is the treatment for hypothermia during anesthesia?

• A. Cold blankets
• B. Increase oxygen
• C. Lower vaporizer
• D. Active warming

Answer: (D)

Hypothermia during anesthesia happens because anesthetic drugs blunt the body's thermoregulation and promote heat loss, so the goal is to actively add heat and reduce ongoing heat loss to restore normal temperature. Active warming provides external heat input, using methods like forced-air warming blankets, circulating warm water devices, warmed IV fluids, and warmed humidified gases. This directly raises core temperature and helps prevent complications associated with perioperative hypothermia, such as coagulopathy, shivering, and impaired wound healing. Passive measures like simply covering with blankets or relying on the room environment are less effective and slower at correcting hypothermia under anesthesia. Increasing oxygen helps with gas exchange but does not address body heat. Lowering the vaporizer reduces anesthesia depth but does not rewarm the patient.
