There are many causes of heat stroke in high-temperature operation of the plant, and if coupled with poor ventilation, is prone to heat stroke; agricultural and open-air operation, under direct sunlight, coupled with the earth by the sun exposure, temperature of the atmosphere re-rise, people of meningeal congestion, caused by the cerebral cortex ischemic stroke, the air humidity to enhance easy to induce heat stroke; in public places, family, crowded concentration, concentration of heat, cooling difficulties.
According to the severity of clinical manifestations, heat stroke can be divided into precursor to heat stroke, mild stroke and severe heat stroke, the relationship between them is gradual.
★ aura symptoms of heat stroke
High temperature, headache, dizziness, thirst, sweating, weakness sour, inability to concentrate, incoordination and other symptoms. Normal or slightly elevated body temperature. Such as the timely transfer to a cool and ventilated place, add water and salt, can be restored within a short time.
★ Mild symptoms of heat stroke
Body temperature is often above 38 degrees. Of dizziness, thirst, often outside the flushing, sweating, skin burning, such as performance, or there clammy, pale, blood pressure, pulse and fast performance. If timely treatment, can often be restored within a few hours.
★ symptoms of severe heat stroke
As the name suggests, is the most serious heat stroke in a situation, if not where would be life-threatening. Such heat can be divided into four types: heat cramps, heat exhaustion, sunstroke and heatstroke.
Characteristic symptoms of heat cramps: a lot of sweat and occur in thirst, drinking water and more salt added sodium chloride concentration in the blood caused by lack of significant decreases rapidly. Heat stroke occurs when the muscles of such a sudden paroxysmal spasm of pain.
Characteristic symptoms of heat exhaustion: This heat stroke often occurs in the elderly and people who have failed to adapt to high temperatures. The main symptoms are dizziness, headache, palpitation, thirst, nausea, vomiting, clammy skin, blood pressure, fainting, or blurred consciousness. At this time the body temperature normal or slightly high.
Sunstroke symptoms characteristic: the reasons for such heat stroke just as its name, because directly under the scorching sun exposure, intense sunlight to penetrate the skin and skull head caused brain cell damage, thus resulting in brain tissue edema; mainly due to head injury, so the beginning there is a severe headache of discomfort, nausea, vomiting, irritability, followed by coma and convulsions may occur.
Characteristic symptoms of heatstroke: There are some people engaged in manual labor in a hot environment for longer periods, excessive body heat, and lack of heat, leading to a sharp increase in body temperature. There are a lot of the early onset of cold sweat, then no sweat, rapid shallow breathing, pulse rate, irritability, blurred consciousness, blood pressure, falling limbs, convulsions to coma with development; can produce severe cerebral edema, pulmonary edema, heart failure.
