Common sense of heatstroke

1. Seek all the knowledge about heatstroke.

Summing up heatstroke refers to the symptoms of disorder of body temperature regulation, disorder of water and electrolyte metabolism and impairment of nervous system function under the long-term action of high temperature and thermal radiation.

Patients with brain diseases, the elderly and the infirm, and women with poor heat tolerance are particularly prone to heatstroke. There are many reasons for entering the topic of heatstroke. Working in a high-temperature workshop, if coupled with poor ventilation, is prone to heatstroke; In agriculture and open-air operations, the direct exposure of the sun, coupled with the exposure of the earth, makes the atmospheric temperature rise again, making people's meninges congested and cerebral cortex ischemic, causing heatstroke, and the increase of humidity in the air is easy to induce heatstroke; In public places and families, people are crowded and concentrated, heat production is concentrated, and heat dissipation is difficult.

The symptoms are 1, fever, fatigue, burning skin, dizziness, nausea, vomiting and chest tightness. 2, irritability, rapid pulse, blood pressure drop.

3. Severe patients may have severe headache, fainting, coma and spasm. Clinical classification 1, threatened heatstroke: sweating, thirst, fatigue, dizziness, dizziness, tinnitus, nausea, palpitation, inattention, numbness of limbs, etc. Occurs in a high temperature environment, and the body temperature does not exceed 38℃.

2. Mild heatstroke: the above symptoms are aggravated, the body temperature is above 38℃, facial flushing is pale, sweating, the skin is wet and cold, the pulse is weak, the heart rate is fast, the blood pressure drops, respiratory and circulatory failure and other symptoms and signs. 3, severe heatstroke: (l) heatstroke and high fever: the function of the thermoregulatory center is disordered, it is difficult to dissipate heat, and the body accumulates too much heat.

At first, I had symptoms of threatened heatstroke, and then I had headache, anxiety, lethargy and even coma. Flushing face and dry skin.

Blood pressure drops, shortness of breath, and heart rate increases. The body temperature is above 40℃.

(2) heatstroke failure: water and salt are lost due to excessive sweating, and blood volume is insufficient. The clinical manifestations are pale face, cold skin, weak pulse, low blood pressure, shortness of breath, unconsciousness, low axillary temperature and anal temperature of about 38.5℃.

(3) heatstroke spasm: After sweating a lot, you only drink plenty of water and don't supplement salt, so the blood sodium and chlorine are reduced, and the blood potassium can also be reduced. The patient is thirsty and has little urine.

Muscle spasm and pain, normal body temperature. (4) Heatstroke: Due to the strong sunlight in the head, a large amount of ultraviolet rays enter the skull, which raises the intracranial temperature (up to 465,438+0 ~ 42℃), resulting in edema and congestion of the brain and meninges.

Therefore, there will be severe headache, dizziness, nausea, vomiting, tinnitus, dizziness, irritability, disturbance of consciousness and severe convulsions and coma. The body temperature can be slightly raised.

The above situations can sometimes appear in combination. Check 1, blood routine, urine routine, stool routine.

2. Detection of liver function, renal function, electrolyte and inorganic elements. 3. Cardiovascular examination.

4.CT examination. 5, blood gas and acid-base balance index detection.

Treatment 1, immediately transferred to a cool place or an air-conditioned room, and given physical cooling. In severe cases, the temperature dropped rapidly, an ice cap was put on the head, an ice pack was placed near the neck and axillary inguinal artery, and compound chlorpromazine was injected intravenously. 2. Correct the balance between water and electrolyte.

3. Prevent complications and control infection.

Tips for heatstroke prevention and cooling in summer

Here are some common sense of life for your reference. Please take measures to prevent heatstroke and cool down, and pay attention to your health.

First, replenish water in time but drink less drinks. Juice, cola, sprite, soda and other drinks contain more saccharin and electrolytes. Drinking too much will have adverse effects on the gastrointestinal tract and affect digestion and appetite. So drink more boiled water or light salt (sugar) boiled water in summer.

Second, it is not advisable to binge drink after being thirsty. After sweating a lot in labor and sports, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be supplemented appropriately, because after sweating a lot, too much salt is lost in the human body, accounting for about 0.5% of sweat. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder.

3. The strongest time of solar short-wave radiation is around 10-15. Try to avoid going out during this time, and apply some sunscreen skin care products to your skin. It is best to wear light clothes in summer.

Fourth, it is not advisable to drink too much. In summer, human body is easily affected by temperature, and excessive damp heat is the cause of skin sores, carbuncle and toxic swelling. If you drink a lot of white wine, it will contribute to dryness and dampness, which is tantamount to adding fuel to the fire.

Fifth, the diet should not be too light. In summer, people have long activities, sweat a lot and consume a lot. They should eat more nutritious foods such as chicken, duck, lean meat and fish eggs to meet the metabolic needs of the human body.

Sixth, the nap time should not be too long. If the nap time is too long, the central nervous system will deepen the inhibition, the cerebral blood flow will be relatively reduced, and the metabolic process will slow down, leading to discomfort after waking up and more sleepiness.

7. Avoid "rapid cooling" after heating. In hot summer, when people go out or come back from work, they like to either turn on the electric fan or take a cold bath immediately, which will make the pores of the whole body close quickly, but the heat in the body is difficult to dissipate, and it will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which makes people dizzy.

Eight, air conditioning indoor and outdoor temperature difference should not be too big. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees.

Nine, it is not appropriate to wear metal jewelry. Some metals in metal ornaments are stained with sweat, and the skin will be red or itchy when worn, which may easily lead to contact dermatitis.

In order to prevent the occurrence of heatstroke, in addition to avoiding going out from the morning to 2 pm in the strongest sunshine 10, necessary protective measures should be taken: ① keep indoor ventilation and lower the room temperature, at least with electric fans; ② Working hours at high temperature should not be too long, and should not exceed 8 hours every day; (3) Reduce labor intensity, prepare heatstroke prevention and cooling drinks, and supplement brackish boiled water or salty drinks as much as possible; Ensure adequate sleep and eat more nutritious fruits and vegetables. ⑤ Try to penetrate the air-cooled cotton-padded jacket.

How to prevent heatstroke in hot summer?

In recent days, the hot weather has scorched the land of Sanjin, and people who come to major hospitals in the provincial capital for heatstroke are in an endless stream. To this end, this edition will provide you with some tips for heatstroke prevention and cooling. I hope it can provide you with a cool and comfortable life.

Eight kinds of people are prone to heatstroke.

Compared with ordinary people, some people with poor health or other diseases are more prone to heatstroke, so in hot weather, they and their families should pay more attention.

Due to the atrophy of sweat glands, the function of circulatory system declines in the elderly, and the body is not well cooled.

Pregnant and lying-in women are weak because of their great physical exertion during pregnancy or postpartum. If they stay indoors with poor ventilation and high temperature, they are prone to heatstroke.

Infants and young children have underdeveloped systems, poor thermoregulation function and more subcutaneous fat, which is not conducive to heat dissipation.

Hot weather will excite the sympathetic nerves of patients with cardiovascular diseases and increase the cardiovascular load. Especially for people with heart failure, the heat in the body can not be distributed and accumulated in time, which is easy to suffer from heatstroke. The body of diabetic patients is slow to respond to the temperature changes in the internal and external environment. Although heat has accumulated in the body, the patient's conscious symptoms appear late, which is easy to cause heatstroke.

Some patients with infectious diseases, because bacterial or viral infection can make the human body produce endogenous pyrogen, so that the body can accelerate the production of heat. Inflammation can also cause the body to release some substances, causing vasospasm and contraction, which is not conducive to heat dissipation and is prone to heatstroke.

The blood pressure of malnourished people drops because of lack of nutrition, which reflexively causes vasoconstriction. They are also prone to recurrent diarrhea, leading to dehydration and electrolyte disorders and heatstroke.

People who take antihistamines, anticholinergic drugs, sleeping pills, etc. There will also be vasoconstriction, which will lead to disorder of thermoregulation center and easy heatstroke.

Drink more light salt water and go out less in the afternoon.

Most people suffering from heatstroke in summer are migrant workers. The main factors leading to heatstroke are high labor intensity, long working hours, poor living environment, stuffy and unventilated rooms and malnutrition.

In addition, patients who are old and weak, pregnant, obese, hyperthyroidism, diabetes and cardiovascular diseases are also prone to heatstroke. Therefore, once dizziness, fatigue, dry mouth, nausea and vomiting, fever, convulsions, convulsions, anhidrosis, dyspnea and other symptoms appear. When it happens, you should immediately rest in a cool and ventilated place or wet compress with cold water and ice water, and then go to the hospital immediately. If the treatment is not timely, it will easily lead to complications and even death.

In order to prevent the occurrence of heatstroke, in addition to avoiding going out from the morning to 2 pm in the strongest sunshine 10, necessary protective measures should be taken: ① keep indoor ventilation and lower the room temperature, at least with electric fans; ② Working hours at high temperature should not be too long, and should not exceed 8 hours every day; (3) Reduce labor intensity, prepare heatstroke prevention and cooling drinks, and supplement brackish boiled water or salty drinks as much as possible; Ensure adequate sleep and eat more nutritious fruits and vegetables. ⑤ Try to penetrate the air-cooled cotton-padded jacket.

4. Urgent for heatstroke prevention knowledge publicity materials.

Prevention and precautions of heatstroke:

1. Drink more water. In hot weather, regardless of the amount of exercise, we should increase the intake of liquid. Don't wait until you feel thirsty to drink water. For some patients who need to limit liquid intake, the amount of drinking water at high temperature should be in accordance with the doctor's advice.

2. Pay attention to supplement salt and minerals. Alcoholic drinks and high-sugar drinks will make people lose more water and should not be drunk at high temperature. At the same time, avoid drinking too cold frozen drinks to avoid stomach cramps.

3. Eat less high-oil and high-fat foods to reduce human calorie intake.

4. Wear light, loose and light clothes.

5. Try to move indoors. If possible, you should turn on the air conditioner. If there is no air conditioner at home, you can turn to public places such as shopping malls or libraries for help in the summer. Although the use of electric fans can temporarily relieve the thermal sensation, once the temperature rises above 32.2 degrees Celsius (90 degrees Fahrenheit), electric fans will not help to reduce the occurrence of high-temperature related diseases such as heatstroke. Taking a cold bath or turning on the air conditioner is more effective for cooling the human body.

6. When going out, you should apply UVA/UVB sunscreen with SPF 15 or above, wear a wide-brimmed hat and sunglasses, or use a sunshade.

7. Travel as far as possible to avoid the time around noon, outdoor activities as far as possible in the shade.

8. Outdoor sports should be reduced at high temperature. If you need outdoor sports, drink 2-4 non-alcoholic cold drinks every hour. Sports drinks can help replenish salt and minerals lost by sweat.

9. Travel by car at high temperature, and don't leave children and pets in the car when you leave the parking lot.

10. Although all kinds of people may be affected by high temperature heatstroke, infants, people over 65 years old, patients with mental illness and patients with chronic diseases such as heart disease and hypertension are more likely to be in danger and need special attention. For these high-risk groups, special attention should be paid in hot weather to observe whether there are signs of heatstroke in time.

5. What is the common sense of heatstroke prevention in summer?

In the hot summer, the heat is unbearable.

Healthy eating habits and reasonable living habits are very important for relieving summer heat and preventing heatstroke. The sunshine is long in summer, early in the morning and late in the evening.

Therefore, daily life and routine should be adjusted accordingly, and it is better to go to bed late and get up early. When going out, it is best to wear light-colored long-sleeved clothes such as cotton and hemp, and wear less chemical fiber clothes, so as to avoid the heat from being distributed in time when sweating heavily.

Some people like to do things with * * * tops. In fact, they are not cool, but they will get sunburned by ultraviolet rays. Summer heatstroke is often caused by excessive loss of body fluids and sodium in the body. According to the temperature, drink more 1.5 to 2 liters of water every day, preferably some salty boiled water or salty tea, which can supplement the salt lost in the body, thus achieving the effect of heatstroke prevention and cooling.

Here are some methods to prevent heatstroke and cool down. You might as well try. Best drink: boiled water-Chinese medicine calls boiled water "the king of all medicines".

Drinking boiled water should choose fresh cold boiled water (20℃ to 25℃) that is naturally cooled after boiling. This kind of boiled water has specific biological activity, and it is easy to enter cells through the cell membrane and be quickly absorbed and utilized. You'd better add some salt to drink boiled water. Salt can replenish the loss of sodium in the body.

Tea potassium is an important trace element in human body, which can maintain the normal function of nerves and muscles, especially the normal movement of myocardium. Tea contains more potassium, accounting for about 1.5% of its proportion.

Potassium is easily excreted with sweat, and tea with suitable temperature can quench thirst and fatigue, and it is also the first choice drink in summer. Chrysanthemum tea-Chinese medicine says that chrysanthemum is sweet, bitter and slightly cold.
