If the patient is sunburned, it is important to consider that the patient is suffering from heat stroke, and the patient should be transferred to a cool, dry, ventilated environment away from the heat stroke environment for treatment. Heatstroke types and causes are different, but the basic treatment measures are the same. First, cooling treatment: rapid cooling is the basis of treatment, rapid cooling determines the patient’s prognosis. 1, extracorporeal cooling: transfer the patient to a well-ventilated low-temperature environment, take off the clothes, while skin and muscle massage, to promote the dissipation of heat. No defecation patients, cold water bath or ice bath, the patient’s body (except the head) as much as possible immersed in 2.0 ~ 14.0 ℃ cold water, and constantly stirring the water to keep the skin surface with cold water, placed around the top of the head with a wet towel wrapped in ice. This method can reduce body temperature from 43.3°C to below 40.0°C within 20 minutes. Evaporative cooling is used for those who are deficient, such as repeatedly wiping the skin with 15°C cold water, using an electric fan or air conditioner. When the body temperature drops to 39 ℃, stop cooling.2, in vivo cooling: in vitro cooling is ineffective, use ice saline for gastric or rectal lavage, or use sterile saline for peritoneal cavity lavage or hemodialysis.3, medication cooling, control chills. Second, the treatment of complications: 1, comatose patients should be endotracheal intubation, airway protection to prevent aspiration. Intravenous mannitol infusion for increased intracranial pressure. In case of epileptic seizure, diazepam should be infused intravenously.2. Fluid resuscitation: Hypotensive patients should be infused intravenously with saline or lactated Ringer’s solution to restore blood volume. Do not use vasoconstrictor drugs, so as not to affect the skin heat dissipation. 3, multi-organ failure: should be given symptomatic supportive therapy.
