Summer health reminder | hot summer alert high temperature killer

Every summer, high temperatures are one of the severe harmful factors. This year, high -temperature weather is even more high, high, high in temperature and long -duration, and more and more areas involved. High -temperature red early warning has become a hot search screen. "Hot Dead" is no longer an adjective of high temperature and unbearable, but the description of real events. Thermal radiation disease has become a hot spot for recent public attention. However, fever irritation is not equal to heat stroke. It is only one of the diseases caused by severe heat stroke. Some symptoms and signs of symptoms and signs are highly vigilant before the occurrence of thermal ejection.

Threatened heat stroke

In high temperature environments, dizziness, headache, weak limbs, thirst, sweating, panic, chest tightness, inattention, uncoordinated movements, etc., normal or slightly increased (generally no more than 38.0 ° C), can be accompanied There are redness, skin burning, etc. At this time, the patient should be transported to the cool and ventilated place in time to supplement the water and salt. The symptoms can disappear after a short period of time.

Heat stroke

According to different clinical manifestations, heat stroke can be divided into three types: heat spasm, thermal failure and thermal ejection disease.

1. Hot spasm

It is mainly caused by a large amount of sweating caused by high temperature, and the electrolyte balance disorders caused by the loss of water and salt. It is manifested as the whole body muscle spasm and severe pain. It is the most obvious in the gastrocnemius muscle. The spasm is generally symmetrical, sometimes alleviated, sometimes alleviated.

2. Frequent failure

It is mainly caused by the dilatation of peripheral blood vessels and a large amount of water loss caused by high temperatures, causing a decrease in circulating blood volume, and rapid onset. It is dizziness, headache, panic, sweating, thirst, nausea, vomiting, and then the skin is cold, pale, syncope, and short blood pressure, and the body temperature is not higher. The proportion of thermal failure in the elderly or patients with cardiovascular disease is higher.

3. Fever

Most patients are ill, and a few have the front -wheel drive period, manifested as weakness, headache, dizziness, nausea, vomiting and urine. Typical symptoms are rapid high fever, body temperature is often above 40 ° C, the skin is dry, burning and without sweat, accompanied by different degrees of conscious consciousness, such as the body temperature exceeding 41 ° C and a longer duration. Internal coagulation of sex vascular, the prognosis is poor.

When severe heat stroke occurs, it should be sent to the hospital immediately. The principle of treatment is to reduce body temperature (physical cooling or drug cooling), correct water and electrolyte disorders, and actively prevent shock and brain edema. Patients with hot spasm can take salt -containing beverages, if necessary, you can push the calcium glucose liquid. Patients with fever, first lie in a cool place, can be recovered after supplementing water and salt. Sometimes intravenous injection of 50%glucose solution can help recover.
