When exposed to high temperature, sweating, limb weakness, dizziness, thirst, headache, inattention, dizziness, tinnitus, uncoordinated movements, etc. It may occur when the body temperature rises or does not rise. If you leave the high temperature environment and move to the shade, you can recover in a short time by timely ventilation and cooling to replenish cold salt water.
2, mild heatstroke.
The symptoms of threatened heatstroke continue to worsen, and the body temperature rises above 38 degrees Celsius, resulting in skin burning, flushing or dehydration (such as cold limbs, pale face, decreased blood pressure, and accelerated pulse). ). Using the same treatment as threatened heatstroke, you can recover within a few hours.
3. Severe heatstroke.
Include heat spasm, heat exhaustion and heatstroke. Heat spasm. More common in healthy young people.
It is characterized by short and intermittent muscle twitching during or after training in high temperature environment, which usually lasts for about 3 minutes.
Patients often have no obvious temperature increase, which may be related to a large amount of sodium deficiency or hyperventilation in the body when they only supplement water without salt and sweat a lot. Heatstroke failure.
More common in the elderly, children and patients with chronic diseases. The patient has a group of clinical syndromes characterized by insufficient blood volume, such as hyperhidrosis, fatigue, fatigue, dizziness, headache, decreased judgment, nausea and vomiting.
At this time, the patient's body temperature increased and there was no obvious nervous system damage. If not diagnosed and treated in time, it can develop into heatstroke. I have heatstroke.
It can be divided into two types: labor heatstroke and non-labor heatstroke. Exercise heatstroke.
More common in healthy young people (such as athletes, training officers and soldiers). It is characterized by long-term exposure to high temperature, high humidity and windless environment, and after a period of intensive training or heavy physical labor, symptoms such as fever, headache, sudden fainting and unconsciousness appear. Then the body temperature rose rapidly, reaching more than 40 degrees Celsius, causing delirium, lethargy and coma.
Patients may be accompanied by rhabdomyolysis, acute renal failure, acute liver injury, disseminated intravascular coagulation (DIC) and other manifestations of multiple organ failure, with rapid deterioration and extremely high mortality. Non-labor heatstroke.
It often occurs in the elderly, the infirm (children) and chronic patients, and generally has a slow onset. At first, the symptoms were not easy to find. 1 ~ 2 days later, the symptoms worsened, and confusion, delirium and coma appeared. The patient's body temperature can be as high as 40 ~ 42 degrees Celsius, and the rectal temperature can be as high as 46 degrees Celsius, which can cause heart failure and renal failure.
