High temperatures and alert radical diseases in the next day: Different from heat stroke, the mortality rate is higher

Different from heat stroke, the mortality rate is higher--

High temperature for several days, alert thermal radiation disease

At 14:30 on July 13th, the temperature of the Shanghai Xujiahui Station reached 40.9 ° C, which was the highest temperature record since the local meteorological record (since 1873). "The Chongqing Museum has been hot", "The fan fan has become a hair dryer", "Men's hydrophilic diseases are damaged as cooked" ... In the past few days, various types of topics about high temperatures frequently appear on the Internet heat Search. According to reports, in the past week, Zhejiang has continued to have high temperatures, and patients with heat stroke have been continuously sent to the hospital. Multi -person diagnosis of fever and death has been diagnosed.

It turned out that "hot death" was not just talking casually. So what is fever?

"Simply understand that the most dangerous and serious degree of heat stroke is thermal radiation. The range of normal body temperature fluctuations in normal human body is very narrow, and the cells that constitute the human body can only survive and play normal physiological functions only at about 37 ° C. When you do not retreat above ° C, the body protein degeneration and functional loss will occur, and even cell necrosis will occur. In severe cases, there will be some dysfunction of the organs, which is life -threatening. "Zhang Xiangyang, director of the emergency department of Beijing Tsinghua Chang Gung Hospital, told reporters that reporters told reporters The mortality rate of thermal radiation disease is very high, up to 40%to 50%. For people over 50 years old, the mortality rate even reaches about 70%.

Understanding thermal shooting disease is inseparable from the keyword "heat stroke".

According to the "Consensus and Treatment Experts in China", fever is a severe fatal disease caused by thermal factors to cause the body. That is, the core temperature is higher than 40 ° C, and the central nervous system is abnormal, such as changes in mental state, convulsions, or coma, and accompanied by multiple organs damage. In severe cases, it is life -threatening.

Who are easy to get fever? "High temperature, high humidity climate and high -intensity physical activity are the main pathogenic factor." Zhang Xiangyang introduced that classical thermal radiation diseases are common in young people, pregnant women and old -age bodies, as well as damage to chronic basic diseases or immune functions. Individuals, the adverse effects of heat waves on human functions may last about 1 week. "There is also a labor -type thermal radiation disease that is easier to recruit high -intensity exercise and labor in high temperature and high humidity environment. Healthy young people in summer strenuous exercise. "

"The development of fever is a process." Zhang Xiangyang pointed out that heat stroke will develop from threatened heat stroke, light heat stroke to severe heat stroke, that is, the fever radiosis. At this time , Heat failure, coma or shock.

"Severe heat strokes, the main manifestations are headaches, dizziness, sweating, fatigue, inconsistent attention. At this time, we must quickly get rid of the environment of high temperature and high humidity, and lie in a cool and ventilated place to avoid high -intensity exercise and heavy physical labor. If possible, go to the air -conditioned room to rest, and remove the clothes as much as possible to help heat dissipation, and timely supplement the salt -containing cool drinks, which can be effectively relieved. "Zhang Xiangyang explained that if the threatened heat stroke is not discovered and processed in time, it will progress to light Symarking the heat, the body temperature is significantly higher -often higher than 38 ° C, the color of the face red and sweating in large amounts. In severe cases, there are false performances such as whitening, cold sweat, and unstable standing. At this time, if timely treatment and treatment are obtained, the condition can still be relieved quickly, but if it does not attract attention and develops to severe heat stroke, the condition will turn sharply and prognosis.

What are the serious hazards? "The first is the central nervous system. The typical symptoms are conscious disorders or even coma. There may also be convulsions. CT examination can see cerebral edema." Zhang Xiangyang said that at the same time, it will also cause multiple organs to fail, such as liver and kidney failure, coagulation function Ferry, horizontal muscle dissolution, etc.

Zhang Xiangyang reminded that we must improve the vigilance of threatened heatstroke symptoms, and timely identify and avoid aggravation and development of the condition. Secondly, pay attention to the relatively weak special groups such as the elderly and children. It may be strict in summer, and even because they are afraid of a cold, they are unwilling to blow air conditioning, which leads to heat stroke. The symptoms of such people are more hidden and it is not easy to detect. Even the summer maternal confinement did not turn on the air conditioner and covered it, which led to reports of family tragedy.

"Fever, focusing on prevention!" For labor -type thermal radiation disease, Zhang Xiangyang suggested that it is best to protect it when it is necessary for outdoor activities. Outdoor area activities. "Also pay attention to replenishing moisture and salt, or sports drinks containing electrolytes." Once you are suspected to occur under high temperature and high humidity conditions, you must leave the high temperature and high humidity environment, such as entering the air -conditioned house, wipe the body with warm and cold water to cool down to cool down. If there is a coma, you should seek medical treatment in time. Zhang Xiangyang reminded that the body temperature of heat stroke is not the "fever" in the usual sense, so it is not possible to use the usual "antipyretic medicine".
