What measure is key to maintaining normothermia during burn resuscitation?

• A. Use warmed IV fluids, warmed humidified oxygen, and warming blankets
• B. Use only warmed IV fluids
• C. Use room temperature oxygen and no warming
• D. Avoid warming to prevent overheating

Answer: (A)

Maintaining normothermia during burn resuscitation requires actively preventing heat loss from all routes, since burns create a high risk of rapid cooling. Providing warmed IV fluids helps stop the infusion itself from lowering core temperature, which can happen when large volumes are given in a cold state. Warming the oxygen and making it humidified reduces heat and moisture loss through the respiratory tract, which is another significant source of cooling during resuscitation. Warming blankets or other active warming devices address heat loss from the skin and environment, helping to keep peripheral and core temperatures stable.

Using only warmed IV fluids would miss the cooling that can occur from inhaled air and external exposure. Room temperature oxygen can contribute to cooling and dryness, undermining efforts to stay warm. Deliberately avoiding warming to prevent overheating misreads the goal; during resuscitation the aim is to prevent hypothermia, not to risk overheating, which is much less common and controllable with monitoring.

So, combining warmed IV fluids, warmed humidified oxygen, and active external warming provides a comprehensive approach to keep the patient warm and stabilize physiology during the critical resuscitation period.
