Two days ago, the tragedy of a worker hit the hot search: 
What is heat stroke?
Although we have never heard of the word "heat stroke", everyone must know another word - heat stroke .
is correct! Heat stroke is actually severe heatstroke !
When did heat stroke become so scary? Wouldn't it be better to take a short rest?
Facts tell us that severe heat stroke is dangerous to death. When the human body suffers from severe heat stroke, the body temperature regulation is imbalanced, sweat cannot be discharged, and the heat cannot be discharged from the human body, but is accumulated in various organs of the human body.
Think about it, if you stay in a steam room without air conditioning at 40°C, you will definitely be too hot to bear and unable to work; there will be a lot of heat accumulated around the body organs, and they will definitely be too hot. I can’t stand it and can’t work.
The functions of organs and tissues throughout the body are affected, just like a factory "shut down", and the human body cannot maintain normal functions. Multiple organ and multi-system injuries such as consciousness disorder, rhabdomyolysis, disseminated intravascular coagulation (DIC), acute liver damage, and acute kidney damage may occur, which are life-threatening.
How can long-term outdoor workers prevent heat stroke?
There are two types of heat stroke. The Zhejiang worker who died in the news fell into the labor-related type of heat stroke. is common in healthy young people who undergo high-intensity training or engage in heavy physical labor in high temperature and high humidity environments.
(1) Three environmental factors for the onset of heat stroke
- High temperature:Daily average temperature >30°C, daily maximum temperature ≥37°C;
- High humidity:Relative humidity >73%;
- Windless environment.
Red high temperature warnings have now appeared in many places, and the temperature has reached 37-40°C. Outdoor workers, construction workers, and workshop workers in these areas must pay attention to two other conditions: whether the humidity is too high, and whether the environment is clean. wind. If it is true, be careful and don't push yourself too hard to avoid tragedy.
(2) Symptoms of exertional heat stroke
- Early stage: After a period of physical labor, you suddenly feel general discomfort, fever, headache, dizziness, slow reaction, or sudden fainting, confusion, accompanied by nausea, vomiting, Shortness of breath, , etc.,
- mid-term: then the body temperature rises rapidly to above 40°C, delirium, drowsiness and coma appear. The skin is dry and hot, the complexion is flushed or pale, sweating profusely, cold sweat, then no sweat, tachycardia , shock , etc.
- Late stage: accompanied by severe rhabdomyolysis, so acute renal failure , acute liver damage.
The condition of heat stroke worsens quickly, so it is necessary to detect early symptoms in time and take timely countermeasures to avoid further deterioration.
Elderly people at home also need to be careful about heat stroke
Looking back at the initial news, in addition to the worker in Zhejiang, the news also mentioned a patient: A 70-year-old woman did not pay attention to heatstroke prevention at home and developed high fever and consciousness while taking a nap. He was blurry, his body temperature reached 42.5°C when he was sent to the hospital, and he had multiple organ failure. He is still being rescued.
This is another type of heat stroke: Classic heat stroke. It is more common in the elderly, frail and patients with chronic diseases.
Why is this? The main reason is that many elderly people have poor living conditions. The old houses have poor ventilation, or they are reluctant to turn on the air conditioners. These elderly people often suffer from chronic diseases, so even if they stay at home and meet the conditions of high temperature, high humidity and no ventilation, the same You'll get heat stroke.
- early symptoms: similar to heatstroke symptoms, dry skin, elevated muscle temperature, no sweat, etc.;
- mid-term symptoms: symptoms worsen after 1-2 days, with confusion, delirium, coma, etc., or incontinence of urine and feces, body temperature High, reaching 40 ~ 42°C;
- Later symptoms: heart failure , kidney failure and other symptoms may occur.Like
, classic heat stroke must be discovered and treated in time when early symptoms appear.
How to deal with the symptoms of heat stroke?
The key points are firstly to quickly reduce core temperature, secondly to blood purification and thirdly to prevent and treat DIC. Before medical workers arrive, the core of treatment for ordinary people is early cooling down.
Clinical data show that the mortality rate of heat stroke is closely related to hyperthermia and its duration. If cooling is delayed, the mortality rate will increase significantly. How to do
specifically?
① Immediately take the patient away from the high temperature environment and move to a ventilated and cool place;
② Start cooling down the patient immediately after leaving the high temperature environment, lay the patient down and remove all clothes;
③ Spray the patient with cold water or wipe the whole body with a wet towel;
④ Fan, It can accelerate evaporation and convection heat dissipation;
⑤ Continuously monitor body temperature, cooling goal: quickly reduce core body temperature to below 39°C within 10-40 minutes, and below 38.5°C within 2 hours.
