Beware of Heat Stroke First Aid in Summer Remember the Four Steps

   Since the beginning of summer, there have been many cases of heat stroke patients. Heat stroke is commonly referred to as severe heat stroke. Heat stroke is divided into exertional heat stroke and non-exertional heat stroke. Exertional heat stroke is caused by high-intensity physical exercise in a high-temperature, high-humidity environment and no wind, resulting in a rapid increase in the core temperature of the body, exceeding 40 degrees Celsius. , An extremely serious clinical syndrome with multi-organ and multi-system damage such as disturbance of consciousness, rhabdomyolysis, disseminated intravascular coagulation, acute liver damage, and acute kidney damage. Exertional heat stroke is the most serious type of heat stroke, which is characterized by acute onset and rapid disease progression. If there is no timely and effective treatment, the mortality rate is high. It is common in young people who exercise vigorously in summer. Once the suspected person has symptoms of heat stroke, they should be immediately transferred to the hospital for treatment. Nonexertional heat stroke is seen in elderly, frail, and chronically ill patients, and the onset is usually gradual. Early symptoms are not easy to find, but after 1 to 2 days, the symptoms worsen, confusion, coma, etc., or incontinence, high body temperature, up to 40 to 42 degrees Celsius, accompanied by heart failure, renal failure and other manifestations.
   High fever (body temperature over 40°C), lack of sweating, confusion, convulsions and even unresponsiveness are the three prominent features of heat stroke. For heat stroke first aid, cool down quickly. Remember the four-step first aid of “transfer dressing and clothes turning”. Remove and untie the clothes to facilitate breathing and heat dissipation, quickly move the patient to a cool, ventilated place, and move the patient to an air-conditioned room if possible. For application, use a cold towel or ice pack on the head or place it on the patient’s armpit, thigh root, etc., or rub it with 30% to 40% alcohol, and at the same time use an electric fan or a fan to quickly dissipate heat. If the patient is still conscious, they can take some cool drinks, such as light salt water, mung bean soup or sports drinks, or take traditional Chinese medicines such as Rendan and Huoxiangzhengqi water. If you are not aware of it, do not feed it to avoid aspiration. Transfer, for severe heatstroke patients, they must be sent to the hospital for diagnosis and treatment immediately, preferably in an air-conditioned car.
   Sanitation workers and construction workers who work outdoors for a long time, people who stay in closed rooms and cars for a long time, people with chronic diseases, especially cardiovascular and cerebrovascular diseases, as well as the elderly and infirm, children and pregnant women, are heat radiation high-risk groups of disease.
   So, how to prevent heat stroke? After sweating a lot, you should replenish water in time, and you must ensure that you have enough drinking water when working at high temperatures. It is recommended to minimize the time spent outdoors in hot weather, and prepare for sun protection when going out. It is best to prepare sun umbrellas, sun hats, and light-colored, breathable clothing. Pay attention to maintaining air circulation indoors. When using the air conditioner, avoid blowing against the air vent or the temperature is too low, so as not to induce respiratory, gastrointestinal diseases and joint diseases.
