Which field treatment steps are essential for a severe heat stroke patient with CNS dysfunction?

• A. Provide a slow cooling approach and reassess.
• B. Administer oral rehydration and rest.
• C. Place in shade and give fans only.
• D. Initiate rapid cooling (ice packs to groin/axillae), ensure airway and breathing, provide high-flow oxygen, and expedite transport.

Answer: (D)

Rapid cooling is the priority in severe heat stroke with CNS dysfunction. When the brain is involved, the risk of permanent brain injury and multiorgan failure is high, so you must lower the body's core temperature as quickly as possible. In the field, the most effective approach is rapid cooling using ice packs placed in the groin and under the arms to speed heat extraction from the core. At the same time, secure the airway and support breathing because altered mental status can compromise airway protection, and provide high-flow oxygen to optimize oxygen delivery during this crisis. Transport to definitive care should be started immediately, and continue cooling during transport if possible. Slower cooling or passive measures like shade and fans do not reduce core temperature quickly enough, and oral rehydration with rest does not address the urgent need to lower core temperature in a patient with CNS symptoms.
