The fastest way to recover from heatstroke is to lower the body temperature, including extracorporeal cooling, intracorporeal cooling, and drug cooling. Rapid cooling is the basis of treatment, rapid cooling determines the patient’s prognosis, lowering the patient’s body temperature time period for the “golden half hour”. 1. Extracorporeal cooling: (1) transfer the patient to a low-temperature and rapid circulation of air environment, remove clothing to expose the torso and limbs, bystanders to the patient fanning, etc., to promote heat dissipation. (2) patients without defecation, you can use cold water or ice water immersion bath method to rapidly cool down, the specific method is: the patient’s body as much as possible immersed in 2 ~ 14 ℃ cold water, constantly splash the cold water to the patient’s skin surface, with a wet towel wrapped in ice cubes placed on the top of the patient’s head. (3) patients with defecation, the use of evaporative cooling, the method is: constantly wipe the skin with cold water repeatedly, the use of electric fans or air conditioning as soon as possible to reduce the environmental temperature where the patient is located. 2. In vivo cooling: in vitro cooling effect is not obvious to reconsider, the methods are: gastric or rectal lavage of irrigation, irrigation fluid should be selected with 4 degrees of saline. 3. Drugs to reduce temperature: heatstroke patients with headache and weight, chest and diaphragm stuffiness, epigastric distension, vomiting and diarrhea and other symptoms, can be applied under the guidance of a physician in time patchouli Zhengqi water.
