Good medical sound daily popular science ｜ Nothing of heat stroke "while hot" to collect this heat prevention guide

Recently, the temperature has soared all the way, and even exceeded the 40 ° C mark. Not only did everyone call "hot to melting", but many people have suffered from heat stroke from different degrees and were taken to the hospital for treatment. So why does people heat stroke? How to prevent heat stroke? In this issue, a good medical science daily invitation to Yan Baigang, director of the emergency department of the Third Hospital of Chongqing Medical University, gave you several heatstroke defense guidelines.

Expert profile:

Yan Baigang, director of the emergency department of the Third Hospital of Chongqing Medical University, chief physician, doctor of medical, master's tutor, member of Chongqing Health Popular Science Emergency Expert Library. He has been engaged in emergency medical care and scientific research for 34 years, and has worked in the emergency department of Southwest Hospital and Chongqing People's Hospital for more than 20 years. He has long been committed to emergency treatment of trauma and critical illness.

Why do people have a heat stroke?

When the external temperature continues to exceed 35 ° C, the calories in the human body are almost evaporated by sweating. If you work or move in the environment of high temperature, humidity, and heat radiation for a long time, the heat accumulation in the body can gradually increase, while sweating and evaporation and heat dissipation will become less and less, causing the body temperature regulation function to disordinate, resulting in the body temperature of the human body. Stepping on heat stroke.

Will the consequences of heat stroke be serious?

Many people think that if there is a heat stroke situation, drink some Huoxiang Zhengqi fluid, just take a break. In fact, this treatment method is only applicable to mild heat stroke symptoms. Once the severe heat stroke symptoms of life occur, it is necessary to go to the hospital immediately. So, which symptoms are severe heat stroke?

1. Frequent failure

Mechanism: Due to a large amount of sweating, water loss, excessive sodium loss, and insufficient blood capacity.

Performance: dizziness, headache, pale skin, cold sweat, thirst, decreased blood pressure, fainting or blurred consciousness, normal body temperature.

2, heat cram

Mechanism: After a large amount of sweating, thirsty and drinking too much water, and insufficient salt supplement, reduced the concentration of sodium and chlorine in the blood, causing muscle spasm.

Performance: muscle spasm and convulsions are the most common in gastrocnemiomyopal muscle spasm, and the body temperature is normal.

3, fever irritation

Mechanism: The human body temperature regulation function disorders caused by high temperature and excessive accumulation of heat in the body, which causes damage to neurotrans.

Performance: Taking high fever, sweatless, and conscious disorders as a typical manifestation. In the early days, it was headache, dizziness, general weakness, sweating, and the body temperature rose rapidly soon, up to 40 ° C.

It is worth mentioning that thermal radiation disease can be said to be the most serious heat stroke. The phrase "hot death" is really exaggerated. If this disease is very serious, it will cause death.

How to prevent thermal radiation disease?

1. Avoid high temperature travel, prepare heatstroke prevention drugs

Do not underestimate the temperature of Chongqing's summer, try to reduce the frequency of outdoor sports. Avoid wearing tight, impermeable clothes when you go out, wear a sun hat, sunglasses with wide brim, and apply sunscreen.

Prepare heatstroke prevention drugs, such as Huoxiang Zhengqi Drip Pills, Ten drops of water, human dan, wind and oil essence, etc.; Try to avoid going out during the period from 11:00 to 16:00.

2. Be sure to drink plenty of water

Ordinary people should replenish 1.5 to 2 liters of water every day according to the temperature level. You can also choose to drink tea. Because the potassium content in tea is high, it can help maintain the electrolyte balance of the body fluid. The athletes should drink 200ml of water 1 hour and 10 minutes before exercise. Do not wait for thirst to drink water. After exercise, drink water and supplement salt in time.

It should be noted that it is necessary to avoid drinking cold freezing drinks at high temperature and high fever, which can easily cause gastrointestinal spasm; do not drink alcohol or a lot of sugar drinks, which will cause more body fluids and the body is more lacking.

3. Pay attention to diet

Eat as much as possible in the summer to eat high oil and high -fat foods, and eat foods with high moisture content such as vegetables and fruits. In addition, a variety of nutritious diet should also be intake, including foods of protein and amino acids, vitamins and minerals. Magnesium and potassium electrolyte drinks are conducive to reducing the probability of heat stroke.

4. Guarantee adequate sleep

The summer is short and short, the human body is metabolized, consumed, and it is easy to feel fatigue. Successive sleep can relax the brain and the system of the body, which is good for work and study, but also effectively prevent heat stroke.

Remember this "five moves" after heat stroke to help

1. Move

Quickly move the patient to a cool and ventilated place, let them lie flat, unbutton or take off the coat, use a fan, fan, or turn on the air conditioner to help the patient breathe and heat dissipation.

2. Apply

Apply the head with warm water, and then change it with cold water and ice water.

3. Drink

Drink a salt -containing drink, timely supplement the water required for the body, and add part of the inorganic salt at the same time.

4. Wipe

Due to high temperature, high humidity, and no wind, when the body is difficult to heat the body, you can use cold water or ice water to wipe the bath until the skin is red.

5. Downside

The temperature of the heat stroke is as high as 40 ° C. When symptoms such as coma, convulsions, etc., cool down as soon as possible, and wait for the doctor to come.

Avoid the following methods of fresh stroke first aid errors

1. If you take the antipyretic drugs (such as acetylphenol, aspirin, etc.), if you use antipyretics to cool down, the body's metabolism will increase the burden on the body, and the side effects of the drug will be greater.

2. Excessive wiping alcohol will not only stimulate the skin, but also use excessive or even alcohol poisoning.

3. Appretes ice and ice packs, which causes blood vessels to shrink and cannot smoothly dissipate heat.

4. After the blood vessels soaked in cold water, they can induce cardiovascular and cerebrovascular emergencies after cold shrinkage.

5. Applying topical patent medicine (such as 10,000 gold oil) oily substances are even more not conducive to heat dissipation.(Edit/Zhou Lingling Correspondent/Zhou Yang Tu/Vision China)
