What is the temperature of heatstroke?

Heatstroke is a disorder of body temperature regulation under the influence of high temperature, which is often caused by exposure to hot sun or heavy physical labor in high temperature environment.

Common causes of heatstroke:

Normal people's body temperature can be kept at 37. C or so is the result of balancing heat production and heat dissipation through the role of hypothalamic thermoregulation center. When the ambient temperature exceeds the skin temperature, heat dissipation mainly depends on sweating and evaporation on the skin and alveolar surface. The heat dissipation of human body can also bring the heat of deep tissue to upper and lower tissues through circulating blood flow, and dissipate heat through expanded skin blood vessels, so the more blood flow in skin blood vessels, the more heat dissipation. If heat production is greater than heat dissipation or heat dissipation is blocked, there will be too much heat accumulated in the body, that is, high fever and heatstroke will occur.

Heatstroke can be divided into:

1, threatened heatstroke

In high temperature environment, heatstroke patients have symptoms such as dizziness, dizziness, tinnitus, nausea, chest tightness, palpitation, fatigue, thirst, sweating, inattention, numbness of limbs and so on. At this time, the body temperature is normal or slightly higher, generally not exceeding 37.5. C. This is a harbinger of heatstroke. If measures are taken in time, such as leaving the high temperature scene quickly, the development of heatstroke can be prevented.

2, mild heatstroke

In addition to the symptoms of threatened heatstroke, there are early symptoms of respiratory and circulatory failure, such as flushing or pallor, nausea, vomiting, shortness of breath, sweating, hot or wet skin, weak pulse, increased heart rate and decreased blood pressure. At this time, the body temperature is over 38. C.

3. Severe heatstroke

In addition to the symptoms of threatened heatstroke and mild heatstroke, it is accompanied by fainting, coma, spasm or high fever.

4, severe heatstroke can continue to be divided into:

Heatstroke and high fever, that is, a lot of heat accumulation in the body. People suffering from heatstroke will have drowsiness, coma, flushing, dry and hot skin, no sweat, shortness of breath, increased heart rate, decreased blood pressure and high fever, and their body temperature may exceed 40 degrees.

Heat exhaustion means that there is not a lot of accumulated heat in the body. People suffering from heatstroke may have pale face, cold skin, weak pulse, shallow and rapid breathing, syncope, coma and blood pressure drop.

Heatstroke spasm:

That is, it is not directly related to high temperature, but occurs after strenuous labor and exercise. Because drinking water without supplementing salt after sweating a lot, blood sodium and chlorine are reduced, and blood potassium can also be reduced, resulting in paroxysmal painful muscle spasm (commonly known as cramp), thirst, less urine, but normal body temperature.

Eclipse:

That is, strong sunlight irradiates the head, leading to an increase in intracranial temperature. Patients with heatstroke have severe headache, dizziness, nausea, vomiting, tinnitus, dizziness, irritability, mental disorder, coma in severe cases, and slight increase in body temperature.

Emergency rescue in case of heatstroke:

Get rid of the high temperature environment and quickly transfer the heatstroke victim to a cool and ventilated place to rest. Let it lie flat, raise its head and unbutton it.

Cosmetic liquid:

If heatstroke patients are conscious and have no nausea and vomiting, they can drink salty drinks, tea, mung bean soup and so on. To cool down and replenish blood volume.

Artificial heat dissipation:

You can use a fan to cool down, but you can't blow directly at the patient to prevent catching a cold again.

Ice compress:

Cold compress can also be used on the head. Ice packs should be placed in the head, armpits, groin and other large blood vessels (ice cubes, popsicles, water ice cream, etc.). Put it in a plastic bag and seal it tightly), you can rub it with cold water or 30% alcohol until your skin turns red.

Temperature was measured every 10- 15 minutes 1 time.

Preventive measures and key points of first aid after heatstroke in the field

When outdoor athletes go to Shan Ye, they often run after them. However, when they are exposed to intense sunlight for a long time, the heat and temperature in the body are not fully distributed, which leads to the increase of body temperature, the damage of the thermoregulatory center inside the brain and the cessation of activities. This is heatstroke.

People suffering from heatstroke will have headaches, high fever, vomiting or fainting, and sometimes they will die. So outdoor athletes must pay attention to prevention and first aid. You'd better wear a sun hat to prevent exposure to the sun for too long.

Once heatstroke occurs, first aid should be given as soon as possible to avoid collapse and death. First, move the patient to the shade, loosen or take off his clothes, let him lie down comfortably, and raise his head and shoulders with something.

Cover his head with a cold wet towel, preferably a water bag or an ice bag. Wipe your body with a sponge soaked in alcohol or a towel soaked in cold water, and fan it as cold as possible to let his body temperature drop to normal temperature.

Finally, measure his temperature or observe the patient's pulse rate. If it is lower than 1 10 per minute, it means that his body temperature is tolerable. If it is above 1 10, all cooling methods should be stopped. Observe 10 minutes or so. If the body temperature continues to rise, it should be cooled again.

After regaining consciousness, give salt water to drink, but not irritants.
