Recently, red warnings of high temperature have been issued repeatedly in many places. The maximum temperature in some areas will exceed 40 ℃. High temperature not only makes the human body uncomfortable, but also easily leads to heatstroke, and even life-threatening in severe cases. Among them, heat stroke has attracted the attention of netizens. So, what is heat stroke? What are the consequences of heat stroke? Heat stroke belongs to severe heatstroke Heatstroke is not a single disease, but an acute heat induced disease mainly manifested by central nervous system and / or cardiovascular system disorders caused by heat balance and / or water and salt metabolism disorders under high temperature environment, which can be divided into mild heatstroke and severe heatstroke. The clinical manifestations of mild heatstroke are dizziness, headache, flushed complexion, thirst, massive sweating, general fatigue, palpitations, rapid pulse, inattention, uncoordinated movement and other symptoms, and the body temperature rises to above 38.5 ℃. Severe heatstroke is generally ferocious and may even lead to death, including three types of heat stroke, heat cramp and heat failure, and mixed types can also appear. In the case of heat stroke, high temperature leads to dysfunction of temperature regulation center, which makes the body temperature rise rapidly. When the body cannot regulate its own temperature, heat stroke will occur. In 10-15 minutes, the body temperature can reach more than 40 degrees Celsius. If you do not receive emergency treatment, heat stroke can lead to death or disability. Do these four steps for emergency response The manifestations of heat stroke are diverse, which may include dizziness, pulsatile headache, nausea, extremely high body temperature (oral temperature is greater than 39.5 ℃), red and hot skin, dry and sweat free, fear of cold, fast and heavy pulse, blurred consciousness, slurred speech, unconsciousness, etc. If you see any of the above signs, it means that the situation at this time is likely to be enough to threaten the life safety of patients. While trying to cool the patient, others around should help make an emergency call. First, move the patient to a cool place. Secondly, no matter what method is used, the patient should be cooled quickly. For example: immerse the patient in the cold water of the bathtub; Put the patient under the cold water shower; Spray the patient with cold water for watering flowers; Wipe the patient's body with cold water; Cool and wet towels or ice bags to compress the head, armpits and thigh roots; Or when the weather is dry, wrap the patient in a sheet or clothing soaked in cold water and blow it violently with a fan. Third, monitor the patient's temperature and keep trying to help the patient cool down until the temperature drops to 38 degrees Celsius. Fourth, if the emergency personnel fail to arrive in time, please continue to call 120, 110, etc. for more guidance and help. It should be noted that the patient should not be given water. Sometimes, patients' muscles will twitch involuntarily due to heat stroke. When this happens, the patient should be prevented from hurting himself. Don't put anything in the patient's mouth and don't try to feed him / her with liquid to replenish water. If vomiting occurs, please turn the patient's body over and lie on his side to ensure that his respiratory tract is unobstructed. In addition, it should be reminded that the above self-help measures can not really replace the role of medical treatment. They can help people self identify the body's early warning signals and respond in time to prevent the further deterioration of heatstroke, but it is still necessary to get professional medical assistance as soon as possible. The best way to prevent heatstroke is to keep cool. In hot weather, simple changes in drinking water, behavioral activities and clothing can prevent heatstroke and maintain health. (outlook new era)
