The weather may also be warm!Do not do this when you fall in warmth ...

Many people think that the temperature loss will only happen in winter. In fact, no matter whether it is cold or hot, as long as the corresponding conditions are available and lasting for a period of time, it breaks through the body's defense bottom line, and it may occur if you lose temperature.

Under what circumstances is it easy to warm? How should someone be rescued correctly after someone gets warm? Today we invite two doctors to talk about this issue.

Drunk and rainy rain men's warmth in summer night

The weather was hot, and 35 -year -old Zhao Cheng (a pseudonym) met with friends to drink and drink at night. The friends returned to their friends, and he drank high, drunk alone on the side of the road. When it rained that night, Zhao Cheng was unconscious and lay in the rain like this until one or two hours later was discovered by passers -by. Passengers called 120 to call the ambulance, and Zhao Cheng, who was unconscious, was taken to the Second Affiliated Hospital of Xiamen Medical College.

Li Xiaoyan, chief physician of the Emergency Department of the Second Hospital, said that at the time, the patient was pale and curled up into a ball. He was unclear, and the body surface temperature could not be measured. Initial judgment, the patient's vascular dilation after drinking, and the clothes were soaked. The high temperature evaporation took away a large part of the calorie in the body, which caused warmth for a long time. "It must be rescued immediately. If it is not intervened in time, its cardiovascular and lung may have problems, such as pulmonary edema, atrial fibrillation, ventricular fibrillation, etc., and may even stop breathing and cardiac arrest."

The medical staff of the emergency department took off the patient's wet pants, wiped his body for him, put on dry clothes, wrapped it with a quilt, turned on the air conditioner heating, and put the hot water bag on his armpit, neck and The root of the thigh.

In addition, he injected heated saline and glucose for him to supplement liquid and energy. One hour later, Zhao Cheng's body temperature returned to above 36 ° C. Due to the timely rescue, no complications occurred. After a period of observation, he was discharged smoothly.

Common cause of temperature loss: temperature and humidity wind power

Li Xiaoyan said that it is not uncommon for the warm -up patients in the emergency department of the Second Hospital in the summer. It is the most common situation of drunk and drowning. Some people lose their feet and fall into the water. They have been in the water for a long time. After ashore, they did not replace the wet clothes in time, evaporated at high temperature, and the wind blowing, the body's calories quickly lost, resulting in temperature loss.

Li Xiaoyan said that the temperature of the external environment does not necessarily reflect the true feelings of people's temperature. For example, at a high temperature of 35 ° C, people will feel very hot. When the fan is opened, the temperature remains 35 ° C, and people will feel a lot cold. This is because the wind accelerates the evaporation of the body's sweat and speeds up the heat on the body, which is why it will be warm even in summer. The environmental temperature, humidity, and wind are the three most common causes of warmth.

In the same environment, some people do not feel, and some people are prone to warmth, such as older, weak constitution, fatigue, severe malnutrition, chronic diseases, hypothyroidism, etc. , Antidepressant or drunk, are also prone to warmth.

Ning Yaogui, deputy director, chief physician, and doctor of medicine at Xiamen University's First Affiliated Hospital, said that in addition to the above three factors may cause temperature loss, when the temperature difference between day and night or frozen rain and other disasters, when the human body's heat production capacity is lower than the calories than the calories When the dispersion is lost, the temperature loss may also occur. There is also a special case that may also lead to warmth, that is, after surgery anesthesia. "In order to prevent this situation, it can usually be adjusted by actively heating such as air conditioning, covering blankets,"

The symptoms of the three stages of the warmth are different

Ning Yaogui introduced that in general, there are three stages of the development of temperature loss, namely mild and warm, moderate temperature loss, and severe temperature loss.

In the first stage, the heat of the human body began to lose, and the temperature began to decrease until the core temperature was as low as 32 ° C -35 ° C. At this time, the muscles will constantly shrink and the symptoms of "tremor" occur. His hands are numb, and some complex movements cannot be completed. Some skin will appear goosebumps to reduce body temperature loss. May also feel fatigue, abdominal pain, etc., and sometimes increase urine. At the same time, breathing and heartbeat gradually slowed down, muscles gradually stiff, and patients' actions became slow.

In the second stage, as the heat continued to lose, the core temperature was as low as about 28 ° C -32 ° C. The patient's mouth was unclear, the response was slow, and the situation was stunned. Some patients' mouths, ears, fingers, and toes may become blue, which is a manifestation of ischemia and hypoxia. In a short period of time, people have the illusion of "as if they are in a hot environment." Patients may have an abnormality of undressing, and the result is that more heat loss and the core temperature decline rapidly.

In the third stage, the body temperature dropped below 28 ° C. The expression was unclear, the thinking was slow, the skin became like frostbite, and the blue piece was white. At this time, the pulse, breathing, and heart rate all became slow, blood pressure decreased, muscles became stiff, the heart had fibrillation, and the heart stopped at any time.

【Rescue】

Someone beside me warm

It should be like this

If someone is suddenly warm, how to first aid? Li Xiaoyan said that the patient must be transferred to the place where the back is. If there is a tent, the patient can be transferred. After that, take off the wet clothes on the patient. If there is hot water, you can use the mineral water bottle around him to warm the hot water to warm it for it, and place it on the neck, armpit and thigh roots.

If the patient has a conscious change, it is necessary to be sent to the hospital for further treatment. The hospital's various rescue measures are very complete, including ECG, life signs and custody. Measures such as hot water enema to help patients restore calories. Once he has a severe warmth

Cardiopulmonary recovery

Ning Yaogui specially reminded that once he has a severe temperature, the patient's heart beating is very slow and mild, and the response to the external forces is very sensitive. Even when the patient is moved, most of the movement may cause the heartbeat to stop and die. At this time, do not easily do cardiopulmonary resuscitation. In the cold environment, it is difficult to accurately identify the cardiac arrest. The patient's peripheral blood vessel shrinkage and excessive heart movement cause the pulse to be difficult to touch and the blood pressure is difficult to measure. Especially when the body temperature is <30 ° C, some patients may have wet surface and stiff limbs, and their limbs are stiff. Symptoms such as fixed pupils, fixed pupils, cannot smell and heart sounds, and cannot see the thoracic undulating symptoms such as death, etc., should be judged according to ECG monitoring. If there is a regular ECG rhythm, it should be regarded as the existence of life signs, and it is not advisable to press the chest.

I thought heat stroke

In fact, it's warm

Recently, a news has attracted widespread attention. When a lady played in a drifting scenic spot in Zhejiang, she suddenly pale, dizzy, and stiff limbs. At that time, the temperature was as high as 41 ° C, and the people around thought she had heat stroke, and she kept shouting cold. Later, he was diagnosed with acute temperature loss.

How does heat stroke and warm -up?

Ning Yaogui said that heatstroke is caused by the high temperature caused by heat dissipation disorders. After a long time exposed to high temperature environment, symptoms such as headache, dizziness, thirst, and sweat have occurred. At first, the body temperature was normal or slightly higher. When the core temperature continues to rise to above 38 ° C, in addition to the above symptoms, there will also be flushing, a lot of sweating, hot skin, and wet limbs. The opposite temperature loss is that the body temperature is reduced due to excessive heat loss of the body. When the body temperature is lower than 35 ° C, it begins to be in a temperature loss state. The warmth of the warmth will cause stiffness and cold hair, loss of consciousness, and even coma.

【remind】

Do not drink and warm up in warmth.

Li Xiaoyan reminded that it is best not to be greedy to prevent warmth, and control the amount of alcohol when drinking. During outdoor exercise, do your own protection. If you go to the place where there is water, try to wear quick -drying clothes that help quickly sweat, keep warm and windproof, and so on. To participate in the drift project, it is best to prepare a set of dry clothes, put it in a waterproof bag to carry, and change it as soon as possible after the clothes are wet. Before doing various exercises, you need to consume sufficient nutrition, such as eating chocolate, drinking hot drinks to supplement heat, and do not overdraw your physical fitness. If it feels a little cold, drink hot water quickly. Remember that if you have a temperature loss, you must not drink and warm it. The blood vessels of the body surface will expand after drinking, and the wind will blow, but it will accelerate the evaporation of heat in the body.
