Outdoor heatstroke, sunstroke, and urgency first aid knowledge

In the summer, the grass is abundant and it is a good season for traveling. However, due to the increase of temperature, it is easy to suffer from heat stroke outside. Therefore, when you go out in summer, you need to be especially careful. In the event of heat stroke, you must find a cool place for people with heat stroke to sit and rest. Water, if serious, must be sent to nearby rescue centers or hospitals for prompt treatment.

1. Heat stroke emergency

Summer is a season with more outdoor activities. If you love to run in the wild, don’t you know the danger of “heat stroke”? In the eyes of the average person, all discomfort caused by hyperthermia is called heatstroke. In fact, the discomfort caused by hyperthermia is divided into two types, each with different treatment points:

a cause of heat stroke: Because of the high heat and humidity in the environment, the body temperature cannot be normal and it is caused by sweat perspiration, which leads to sudden rise and damage to brain cells. Symptoms that can be seen: dry red skin, headache, vomiting and dry mouth, low urine volume, superficial breathing, strong and rapid pulse, high body temperature, and finally the patient will be confused and fainted (at this time the patient's blood pressure will be urgent The reason is that the oxygen function of red blood cells is low due to overheating, blood oxygen is insufficient but the blood volume is still enough, and the body has to command higher blood pressure to maintain blood oxygen content.) Treatment: Move the patient to a cool place, supine, give He cooled (you can take off some of the patient's clothing, wipe him with a wet towel or ice, cool, etc., but be careful not to make the patient cold). If the patient is awake, you can give him some water, but do not give hot drinks or stimulants such as coffee; at the same time can use Huoxiangzhengqi water, cool oil, Shidi Shui, Dan and other hot weather. Coma people acupuncture people, Shi Yi points. Sent to hospital for treatment

Causes of heat failure: A lot of sweat due to hot weather, the body lack of water and salt and thus prostration. (In fact, it is a type of shock.) Symptoms that can be seen: tiredness and weakness, pale and cold skin (this is the biggest difference), rapid and weak pulse, dizziness and nausea, unrest, and fainting. (Because the patient loses water, blood pressure drops, and the blood does not carry enough oxygen to the brain, so use a method to save the coma.) Treatment: Move the patient to a cool, cool place (with heatstroke) to allow the patient to lie supine, double up If the foot is awake and does not vomit, give the patient a cup of salt water every 15 minutes for a total of two drinks. Hospital treatment Note: Do not drink anything to fainted patients, so as not to trip patients or liquid into the lungs, it would be more troublesome. Prevention: Prevent heatstroke and cool down during the middle of summer. Classrooms should open windows to allow air to circulate, often sprinkle water on the ground, and include shade curtains. It is not advisable to exercise too much time in the hot noon under strong sunlight during reasonable schedules. Strengthen personal protection, wearing a sun hat, drink refreshing drinks. When you have a headache or panicky, you should immediately go to a cool place to have a rest and drink water.

2. Heatstroke First Aid Words

In summer, due to the excessively high ambient temperature and high humidity in the air, the residual heat in the body is difficult to dissipate, and the heat builds up, causing the body temperature regulation center to get out of control and cause heat stroke. Keep in mind the following five words: When you find a person suffering from heatstroke, you can urgently seek treatment:

shift. Quickly move the patient to a cool, ventilated place while raising the head and unfastening the clothes so that they can breathe and dissipate heat.

apply. Use cold water towels to cover the head, or ice packs, ice cubes placed on the patient's head, armpits, thighs, etc.

promote. Place the patient in water at 4°C and massage the skin of the extremities to expand the blood vessels of the skin, accelerate blood circulation, and promote heat dissipation. When the temperature of the anus drops to 38°C, cooling can be stopped.

Dipping. The patient's body is immersed in a well at about 45 degrees in the well water, about the degree of immersed nipple. In elderly, infirm and cardiovascular patients, the water temperature is too low to tolerate.

rub. Four people rubbed the skin around the patient's body with a towel at the same time, rubbing the skin red, generally rub about 15-30 minutes, then the body temperature can be reduced to 37-38 °C, the brain is not seriously injured who can quickly wake up.

3. Sunstroke emergency treatment

When swimming on the seashore, hiking, or during a hot summer day, due to prolonged sun exposure and lack of protection on the head, sudden high fever, tinnitus, nausea, headache, vomiting, drowsiness, photophobia, etc. are signs of sunstroke. . Severe sunstroke disease can also lead to death. Do not be careless and take urgent action.

first-aid:

The light person should quickly rest in a cool and ventilated place, unfasten the clothes button, belt, and open top. Can serve ten drops of water, Rendan and other drugs to prevent heat stroke.

If the patient's body temperature continues to rise, there are conditions to soak the lower body with warm water in the bath and wipe the upper body with a wet towel.

If the patient is unconscious or paralyzed, he should take a coma. While notifying the emergency center, pay attention to ensure that the airway is open.

Precautions:

1. As a means of cooling, you can also use alcohol to wipe the body and blow the fan, you can achieve the purpose of cooling. However, this method can be used to cool down quickly. If the doctor is not on site, it is best not to use it.

2. Some people have mild symptoms and participate in sports. They should pay more attention to prevent them from getting daily shots.

3. There is also a heat stroke similar to sunstroke. This is caused by excessive heat accumulation due to work or travel in hot weather. The symptoms are dry, hot, sweaty skin, body temperature as high as 42°C, fatigue, headache, dizziness, frequent urination, red color, gait instability, drowsiness, or lethargy. The reasons for the two are somewhat different, but the first aid measures are the same.

4. Emergency treatment

When working in a hot and humid place such as a factory for a long period of time, sometimes suddenly his face becomes blue and he feels headache, nausea, dizziness, and paralysis. This is called enthusiasm. If this disease is not dealt with in time, it will further develop so that consciousness will disappear and eventually die.

first-aid:

1. Light person should quickly lie in a cool and ventilated place to rest, unfasten clothes, belts, open tops, and then drink cold water or salt water.

2. If the consciousness is lost and the convulsions are severe, the patient should be put in a coma position (side-to-side, head-to-back) to ensure that the airway is clear and the emergency center is quickly notified.

3. If the collapsed person wakes up, he should also be taken to the hospital. The patient is forbidden to walk on his own, and atropine and hypnotic and sedative drugs are also prohibited. Precautions: 1) It is a simple and effective method for a hot patient to drink cool salt water (a spoon of salt in a glass of water). Due to the large amount of sweat during enthusiasm, the body lost a lot of water and salt, and the blood was concentrated and poorly cycled. At this time, salt water is life-saving water and it should be immediately replenished. 2.) Enthusiasm is often confused with sunstroke. However, the prominent feature of the disease is that the skin is sticky and the body temperature is not high. Its treatment is somewhat different from sunstroke, and it must be distinguished. Whenever working in a high temperature environment for a long time, you should drink plenty of salt water to prevent the disease. 3) If conditions allow, patients with mild symptoms may be given medicines such as Jen Dan, Shi Di Shui or Huo Xiang Zheng Qi Shui.
