Why is maintaining normothermia during anesthesia important in Fear Free protocols?

• A. Increases metabolic rate and stress during recovery.
• B. Reduces stress, improves recovery, and lowers risk of wound infection and coagulopathy.
• C. Has no impact on healing or inflammation.
• D. Prevents hypothermia but has no other benefits.

Answer: (B)

Maintaining normothermia during anesthesia matters because body temperature directly shapes the body's stress response and healing after surgery. Keeping the patient warm blunts the perioperative stress response, leading to more stable hemodynamics, smoother recovery, and less agitation. Warmth also supports better immune function and wound healing, reducing the risk of wound infection and coagulopathy— since hypothermia impairs platelet function and the activity of clotting enzymes, while also dampening immune cell performance. In Fear Free protocols, minimizing stress and discomfort is a primary goal, and maintaining normal temperature helps achieve that by reducing shivering, pain-related stress, and overall sympathetic activation during and after anesthesia. Temperature control also helps preserve tissue perfusion and predictable drug metabolism, aiding recovery. The other statements miss key benefits: simply stating that normothermia increases metabolic rate and stress is inaccurate, as it’s the absence of normothermia (hypothermia) that generally elevates stress and metabolic demand. Saying there’s no impact on healing or inflammation ignores the clear effects of temperature on immune function and coagulation. And suggesting it only prevents cooling ignores the broader advantages for recovery, infection risk, and coagulopathy.
