What are the symptoms of heatstroke and what should be done?

Heatstroke presents with a variety of symptoms and can be categorized into the following stages according to severity, each requiring corresponding management measures. Symptoms: 1. Early-stage heatstroke: Characterized by headache, dizziness, thirst, excessive sweating, weakness in limbs, and normal or slightly elevated body temperature (≤37.5°C). 2. Mild heatstroke: Body temperature rises above 38°C, accompanied by facial flushing, chest discomfort, hot dry skin, nausea, vomiting, and a drop in blood pressure. 3. Severe heatstroke: Body temperature may reach above 40°C, presenting with absence of sweating, impaired consciousness, coma, muscle spasms, convulsions, difficulty breathing, and potentially multiple organ failure in severe cases. Management: 1. Immediately move the patient to a cool, well-ventilated area and loosen clothing to promote heat dissipation. 2. Use cold water, wet towels, or ice packs for physical cooling to reduce body temperature. 3. Provide electrolyte-containing fluids orally or intravenous hydration to correct dehydration and electrolyte imbalance. 4. Closely monitor the patient's condition; if symptoms worsen, seek immediate medical attention for professional treatment.
