In the past few days, a large area in the north of the mainland has entered the high-temperature scorching mode, and there have been many cases of heat stroke or heat stroke casualties. A couple of minefields to watch out for.
Recently, the continuous high temperature weather has led to an increase in heat stroke patients in many places.
On July 2, a local pick-up guide in Beijing died of heat stroke and was sent to the hospital due to heat stroke while leading a group tour of the Summer Palace, but the rescue was ineffective. The tour guide, surnamed Gong, is 49 years old and has been working as a tour guide for more than 20 years, and because of his seniority, colleagues and friends call him "Brother Gong".
On the day of the accident, the study group received by "Brother Gong" left the hotel at 8 o'clock in the morning and went to the Summer Palace. He chose a walking route of about 1.5 kilometers and the tour lasted about two hours. After the tour, the bus driver found that "Brother Gong" was in a very bad state and was in a coma, so he called the 120 emergency number. After ineffective rescue, "Brother Gong" unfortunately died, and the cause of death was "heat stroke".
Not long ago, Hangzhou Linping District Hospital of Integrated Traditional Chinese and Western Medicine also received the first heat cramping patient this year: 120 emergency personnel sent 79-year-old Grandma Zhang to the hospital for rescue.
At that time, Grandma Zhang was unconscious, her body convulsed from time to time, her whole body was sweating profusely, and her body temperature was as high as 40.2 °C. Combined with other indicators, considering that it is heat cramps, medical care immediately opened two intravenous channels for rapid rehydration, and took treatment measures such as cooling, brain protection, and anticonvulsants, but the situation was not optimistic, and after some diagnosis and treatment, it was sent to the ICU for further symptomatic treatment.
The hospital learned that Grandma Zhang, an elderly man living alone, was sitting at home without air conditioning and fans, and was in a coma due to excessive heat in the room, and was later rescued after being discovered by her children.
At noon on July 6, a group of people rushed with a child to the Qingbo Street Community Health Service Center in Shangcheng District, Hangzhou for help.
The doctor found that the child's body temperature was 39.1 °C, and at the same time the spirit was weak, the eyes were red, the skin was hot, and the limbs were cold.
It is understood that this family recently specially traveled from Quanzhou, Fujian to Hangzhou, the recent outdoor high temperature, the child himself is a little uncomfortable, as a result, he does not like to drink water, as a result of the day in the West Lake play, suddenly fainted.
How to recognize heat stroke symptoms?Heat stroke refers to acute central nervous system and circulatory system dysfunction caused by human thermoregulation function and water salt metabolism disorders in a high temperature environment, high temperature work and high incidence in summer. According to the symptoms of heat stroke, it can be divided into three categories: aura heat stroke, mild heat stroke and severe heat stroke.
Aura heat stroke refers to symptoms such as fatigue, sweating, thirst, headache, dizziness, dizziness, tinnitus, nausea, and chest tightness in a high temperature environment.
Mild heat stroke is mainly manifested as flushing, burning skin, body temperature increase above 38 °C, and can also be accompanied by early symptoms of respiratory failure, such as sweating, pallor, decreased blood pressure, increased pulse rate, clammy and cold skin, etc.
Severe heat stroke can be divided into heat cramps, heat exhaustion and heat stroke according to the symptoms and degree of onset.
Heat cramps: caused by excessive loss of sodium and potassium in the body due to heavy sweating. Presents with muscle spasms with contractile pain, usually in the extremities and abdomen, often symmetrical, sometimes attacking, sometimes relieving. The patient is conscious and has a normal body temperature.
Heat exhaustion: fainting due to increased blood flow to the skin and viscera caused by high fever, resulting in a temporary decrease in blood supply to the brain. Onset is rapid, beginning with dizziness, headache, palpitations, sweating, nausea, vomiting, pallor, clammy skin, decreased blood pressure, and then fainting. Patients have a normal or slightly elevated body temperature and are usually awake after a short rest.
Heat stroke: dysfunction of the thermoregulatory center due to high temperature. Manifested as sudden onset, rapid rise of body temperature can reach more than 40 ° C, red and hot skin and dry without sweat, cold and confusion, slurred speech, unconscious. Symptoms are the most severe and, if left untreated, can lead to death or disability.
Heat stroke is the easiest to target these 7 types of people In case of heat stroke, how to treat it correctly? Under normal circumstances, patients with threatened heat stroke and mild heat stroke can return to normal after on-site rescue, so do not panic too much when encountering heat stroke, and master the first aid method first.
One move: Quickly get out of the hot environment, move the patient to a cool and ventilated place, and at the same time raise the head and untie the pants to facilitate breathing and heat dissipation.
Second compress: the head is first applied with warm water, and then changed to cold water and ice water to help the patient cool down the body temperature.
Three drinks: drink salty beverages, replenish the water needed by the body in time, and replenish some inorganic salts at the same time.
Four rubs: Due to high temperature, high humidity, no wind, and it is difficult for the body to dissipate heat, you can use cold water or ice water to wipe the bath until the skin is red.
Five drops: When the body temperature is as high as 40 ° C, heat stroke patients have coma, convulsions and other symptoms, especially in the face of heat stroke patients, treatment should follow 3 principles:
1. Fast, effective and continuous cooling.
2. Rapid replenishment and expansion. If oral fluids are difficult, intravenous fluids are given.
3. Control agitation and convulsions. At the same time, dial 120 to take the patient to the emergency department of the hospital as soon as possible.
Remember! Never give water to a person who has severe heat stroke.
Because when the patient sweats a lot, sweat will take away a lot of salt, resulting in an imbalance of electrolytes in the human body, if you give him a lot of water at this time, it will further reduce the effective concentration of electrolytes, making the condition worse.
Let's introduce a few more cooling methods:
1. Evaporative cooling: spray with cool water or spray water mist on the skin, and at the same time cooperate with continuous fanning, effective cooling can be achieved.
2. Ice cooling, ice pack physical cooling, pay attention to frostbite.
3. In the case of medical permission, the method of cooling in the body and cooling with drugs can also be used.
Is Huo Xiang Zhengqi Water a miracle medicine for summer? These misunderstandings should be notedMany people think that heat stroke will occur outdoors, or heat stroke will occur when it is hot, in fact, there are some misunderstandings in these cognitions, come and see if you are recruited?
Myth 1: All discomfort in summer is heat stroke?
In summer, many people will have fever, dizziness, headache, chest tightness, shortness of breath, abdominal pain, diarrhea, nausea and vomiting and other uncomfortable symptoms, some people take it for granted that they are suffering from heat stroke, do not need to go to the hospital, drink some Huo Xiang Zhengqi water. Remember not to attribute some uncomfortable symptoms (headache, fever, fatigue, chest tightness or even syncope) to heat stroke, so as not to delay medical treatment and delay the condition.
Myth 2: Heat stroke only outdoors during the day?
Many people will think that only exposure to the sun will cause heat stroke, in fact, the high temperature and humidity environment is the main factor of heat stroke. Studies have shown that in a high humidity environment, even if the temperature is less than 30 degrees, it is easy to cause heat stroke. In particular, some elderly people live in crowded, poorly ventilated and stuffy places, or worry that the air conditioner will waste electricity or do not install the air conditioner, which can also lead to heat stroke.
Myth 3: Heat stroke in hot weather?
Heat stroke can also occur in a closed environment or when wearing too thick clothing. For example, it is thought that confinement is afraid of wind, still wearing thick clothes in summer, or covering sweat with a quilt for cold and fever, etc., will affect the body's heat dissipation, resulting in a sharp increase in body heat in a short period of time, inducing heat stroke. Some children are forgotten in closed cars, even if the outside is in their twenties, the temperature in the car can quickly rise to forty or fifty degrees when the sun is sunny, and if they are not detected in time, they will still suffer from heat stroke.
Myth 4: Is Huo Xiang Zhengqi Water a miracle medicine for heat stroke?
Heat stroke is divided into "yang heat" and "yin heat", yang hot is caused by long-term anticipation in hot weather or exposure to the sun, and yin hot weather is caused by sudden cold in hot weather. Huo Xiang Zhengqi Water mainly treats yin and heat, such as blowing air conditioners on hot days, taking cold showers when sweating, and suddenly entering the cold room from the hot outdoors to get cold, abdominal distention, chest tightness, etc. However, patients with "sun heat" (high fever, confusion, etc. caused by too long exposure to the scorching sun) should take measures such as cool ventilation, physical cooling, and electrolyte drinks as soon as possible, at which time the use of lotus fragrance can not be relieved, but may delay treatment.
Minefield 1: Drink cold "happy water"
Imagine that on a hot afternoon, you have just finished exercising, sweating profusely, and at this moment, you happen to have a cold bottle of carbonated drink that has just been taken out of the refrigerator...
If that's what you really think, then only congratulations... Successfully stepped on a summer minefield.
We do need hydration after a lot of sweating, and opting for a chilled drink is not the best option. Iced drinks not only contain a lot of sugar, but also the temperature is too low, which will irritate the gastrointestinal tract and cause harm to our body.
The correct way to hydrate should be to drink cool white or light salt water, and drink small amounts multiple times.
Minefield two: The diet is too light
Some people say that summer is the season for watermelons. What's more, watermelon is used as a meal.
Some people say that summer is too hot, and they just want to eat some fruits and vegetables, so that they can be healthy and lose weight.
Doesn't the above point sound so exciting that you can't agree more with it in front of the phone screen, right? Then I can only tell you with regret once again, successfully stepping on the thunder ...
Fruits and vegetables do provide the vitamins we need, but they do not provide essential fatty acids and proteins. If you only eat fruits and vegetables, the skin will be rough and inelastic, and the heavy will be sore and pale.
Foods rich in protein and lipids, such as chicken, fish, lean meat, and eggs, can provide nutrients and energy to maintain the normal operation of the human body.
Cooling is precious, weight loss is also expensive, if it is for health, both can be thrown away.
Minefield three: "Cool quickly" yourself
The sun "scorches" the skin in the heat, the midday sun makes it impossible to see directly, and the summer wind blows quietly, leaving only upset heat.
At this time, do you really want to hurry back to the dormitory where there is air conditioning, small beds, sunlight cannot invade you, and heat cannot oppress you?
Or are you already thinking about the question "how many steps does it take to put yourself in the freezer"?
The answer is one step, which is to abandon the idea. Immediately after returning from going out, blowing air conditioners and taking cold showers can easily lead to the rapid closure of pores throughout the body, and it is difficult to dissipate body heat, making people dizzy. At the same time, the temperature of the air conditioner in summer should not be too low, so that the temperature difference between the inside and outside the house can be lower than five degrees.
Minefield four: heat stroke fever, take antipyretic drugs to cool down?
Heat stroke, after sweating profusely, can lead to imbalance in thermoregulation and electrolyte disturbances. Antipyretics can further cause excessive sweating and exacerbate water and electrolyte losses, thereby aggravating the condition. When heat stroke and fever, physical cooling should be mainly used.
Minefield five: heat stroke, rubbing alcohol and cooling oil to cool down?
The most important measure of heat stroke is to lower the body temperature, so is it okay to use alcohol or cool oil? Cooling oil just makes us feel cool and can't cool down. Rubbing alcohol on the skin can be absorbed through the skin, causing further dehydration or worsening heat stroke. Therefore, it is not possible to cool down with rubbing alcohol and cooling oil.
Minefield six: Heat stroke fainting, can pinch people?
Human acupoints have the effect of awakening and enlightening, mainly for shallow coma caused by hypoglycemia and cerebrovascular disease. When heat stroke and high fever syncope, there is no first aid effect in pinching, and it may cause the unconscious injured person's airway to be more unobstructed, which is dangerous. At this time, you need to dial 120 and rush to the hospital for treatment.
Finally, one point reminds everyone that once the body temperature rises above 38 ° C, accompanied by flushing, heavy sweating, burning skin, or cold limbs, paleness, decreased blood pressure, rapid pulse and other manifestations, it is recommended to seek medical attention immediately.
If there is high fever, syncope, shock, coma, convulsions and other manifestations, you need to immediately call the 120 emergency number and send to the hospital for treatment.
