Causes of heat stroke
Heat stroke is generally divided into aura heat stroke, mild heat stroke and severe heat stroke.
In addition to the causes of heat stroke, such as high temperature, direct sunlight, high labor intensity, and lack of air circulation, there is no good rest and physical weakness are also inducers.
Elderly, frail, obese, pregnant women, patients with hyperthyroidism, sweat gland dysfunction (common patients with scars after burns), people who use certain drugs such as atropine are susceptible to heat stroke.
Aura of heat stroke and mild heat stroke
Aura of heat stroke: when exposed to high temperatures, sweating, limb weakness, dizziness, thirst, headache, inattention, dizziness, dizziness, tinnitus, uncoordinated movements, etc. with or without increased body temperature. If you get out of the high temperature environment, move to a cool place, ventilate and cool down in time to replenish cold brine, you can recover in a short time.
Mild heat stroke: symptoms of haemon heat stroke continue to worsen, body temperature rises above 38 degrees Celsius, and symptoms of skin burning, flushing or dehydration (such as wet and cold limbs, pale face, decreased blood pressure, increased pulse, etc.) appear. It is treated in the same way as the aura heat stroke and can recover within a few hours.
How ordinary people can tell if it is heat stroke or not
* High temperature environment, uncomfortable, elevated body temperature, generally mild heat stroke, after giving the corresponding treatment, can be relieved, you can rest and rest and then observe. For about 5 minutes, if there is no sign of relief, call 120 and send it to the hospital for further treatment.
* High temperature environment, people faint or have confusion in thinking to answer the question, indicating that the situation is very dangerous, you need to immediately call 120 for rescue.
Does heat stroke cause death?
The mortality rate of severe heat stroke is as high as 81.3%, and even if the patients who are rescued, many of them have serious sequelae, and the recovery is extremely bad.
There are no statistics in China, but the United States 17.6 to 26.5 people / 100,000 people, Africa 250 people / 100,000 people, in 1995 Chicago continued heat wave caused 3300 people to suffer from heat stroke, of which 600 people died. In 2003, France was hit by a heat wave, and 1,000 people died of heat stroke. Even in Tokyo, Japan in 2020, the death toll from heat stroke was as high as 187.
What can we do in the face of heat stroke?
#发现自己和其他人有先兆中暑和轻症中暑表现时, the first thing to do is to quickly evacuate the high temperature environment that causes heat stroke, and choose a cool and ventilated place to rest; And drink more refreshing drinks with salt.
Question: Can I drink iced drinks?
Answer: Yes, even iced drinks are better than room temperature drinks. You can also apply cool oil, wind oil essence, etc. to the forehead and temporal area (temple), or take Chinese medicines such as Ren Dan, Ten Drops of Water, and Huoxiang Zhengqi Water.
#如果出现血压降低, when prostrating, you should immediately lie flat and go to the hospital in time to inject intravenous saline. For severe heat stroke patients, in addition to immediately transferring heat stroke from the high temperature environment to a cool and ventilated place, they should also be quickly sent to the hospital, and comprehensive measures should be taken for treatment.
#若远离医院, the patient should be removed from the high temperature environment, wrapped in wet sheets or wet clothes and given a strong fan to increase evaporative heat dissipation. While waiting for transport, it is also a good idea to immerse the patient in a lake or river, or even use snow or ice cold.
#若病人出现发抖, the cooling process should be slowed down, as shivering increases core body temperature.
Warning: Temperature should be taken every 10 minutes and the body temperature should not be allowed to drop to 38.3 ° C, so as not to continue to cool down and lead to hypothermia.
How to deal with heat stroke
Ventilate to avoid the heat, replenish moisture and reduce body temperature.
