What is the recommended management for heat syncope?

• A. Move to a shaded area, monitor vital signs, elevate the legs above the heart, cool the skin, and rehydrate
• B. Apply ice packs to the head only and monitor
• C. Give high-flow oxygen and keep the patient upright
• D. Encourage continuous standing activity to promote circulation

Answer: (A)

Heat syncope happens when hot conditions cause blood vessels to dilate and fluid to shift into the legs, reducing blood flow to the brain. The goal in management is to stop further heat exposure, restore circulation, and replace fluids. Move the person to a shaded area to reduce ongoing heat stress. Have them lie down and elevate the legs above heart level to help push blood back toward the brain and improve cerebral perfusion. Cool the skin to help dissipate heat, using fans, removing excess clothing, or applying a damp cloth. Rehydrate with fluids as soon as they can safely drink—oral rehydration or water with electrolytes is appropriate if they’re alert and able to swallow. Throughout, monitor vital signs and watch for any worsening symptoms; seek medical care if there’s no improvement or symptoms recur. These steps specifically address both the need to improve blood return to the brain and to reduce the body’s heat load. Other options don’t tackle both issues: cooling only the head doesn’t address circulation or heat exposure; keeping the person upright can worsen brain perfusion; and continuing to stand promotes blood pooling rather than restoring flow.
