Is cold saline recommended for a patient with a heat-related illness?

• A. Yes
• B. No, unless directed by a physician
• C. Only for dehydration
• D. Only if hypothermic

Answer: (B)

The main idea is that cooling and hydration for heat-related illness should be guided by rapid cooling and safe fluid management, not by giving cold IV fluids as a standard step. Cold saline is not routinely recommended because introducing very cold fluids can cause peripheral vasoconstriction and shivering, which can actually hinder cooling and place stress on the heart, especially in a patient who is already thermally stressed or electrolyte-impaired. Because patient factors vary, cold IV fluids should only be given if a physician explicitly directs it. In practice, you focus on rapid external cooling (evaporative cooling, removing excess clothing) and provide IV fluids per protocol, with the temperature of the IV fluid left to standard care unless there’s a physician order to use cold fluids.
