Common types of heat stroke
The so-called heatstroke is caused by the body's inability to emit excessive heat inside the body in a hot environment. Heat stroke can be divided into the following three types according to the severity of illness:
1. Aura Heatstroke
In the high temperature environment, people with heat stroke appear dizziness, vertigo, tinnitus, nausea, chest tightness, palpitations, weakness, thirst, sweating, inability to concentrate, numbness of the extremities, at this time the body temperature is normal or slightly higher, generally not more than 37.5 °C . This is a sign of heat stroke. If measures are taken promptly, such as quickly leaving the high temperature scene, they can stop heat stroke from happening.
2. Mild heat stroke
In addition to the manifestations of threatened heatstroke, there are early manifestations of respiratory and circulatory failure such as flushing or paleness, nausea, vomiting, shortness of breath, profuse sweating, hot or cold skin, weak pulse, increased heart rate, and decreased blood pressure. The body temperature exceeds 30. °C. If handled in a timely manner, it can often be restored within hours.
3. Severe heat stroke
Severe heat stroke is the most serious form of heat stroke and it can be life-threatening if not treated in time. This type of heat stroke can be divided into four types: enthalpy, heat failure, sunstroke, and heat stroke.
(1) Enthusiasm. Occurred in a large number of sweating and thirst, drinking more water and inadequate salt supplements caused by rapid reduction in blood sodium chloride concentration was significantly reduced.
(2) Heat failure. It often occurs in the elderly and people who are unable to adapt to high temperatures. The main symptoms are dizziness, headache, palpitation, thirst, nausea, vomiting, pale, clammy skin, weak pulse, low blood pressure, shallow and rapid breathing, fainting or confusion.
(3) Live shot disease. Because directly in the hot sun exposure, that is, strong sun exposure to the head, resulting in increased intracranial temperature, thereby causing brain congestion, edema. Since the main cause of injury was the head, the initial discomfort was severe headache, dizziness, nausea, vomiting, tinnitus, vertigo, restlessness, confusion, and coma or convulsions.
(4) Heat shot disease. In the high-temperature environment, it takes a long time to perform manual labor. The body produces too much heat, and the heat is insufficient. A lot of heat accumulates in the body and causes a rapid increase in body temperature, and the body temperature can exceed 40°C. There was a large amount of cold sweat in the hair and early stage, followed by no sweat, rapid breathing, rapid pulse, restlessness, confusion, blood pressure drop, and gradual development of coma with convulsions in the extremities.
Emergency treatment of heat stroke
1. Heatstroke emergency general method
The following general methods are used for emergency relief for the heat-stroked person:
(1) out of high temperature environment. Heatstrokers should be quickly moved to a cool, ventilated place to rest. Keep it flat, raise your head, and loosen the button.
(2) Supplement liquid. If the heat-strokers are conscious and do not have nausea and vomiting, they can drink salty soft drinks, tea, mung bean soup, etc.

2. Two Specific Methods of Rescue for Heat Stroke
(1) Rescue for those who have spent too much time in hot environments. Mainly include the following:
1 out of high temperature environment. Quickly lift the patient into a cool, ventilated environment and lie down. Raise the head slightly and remove the patient's underwear.
2 artificial cooling. Use a paper fan or a fan to fan the wind while brushing or spraying with cold water to speed up the distribution of heat in the patient. Ice cubes can also be placed in the bag and placed on the patient's forehead, neck, underarm and thigh.
3 add liquid. Those who are conscious can feed cool drinks, salted sugar, and Dan, Shi Dihui or Zheng Qi Shui.
4 coma recovery. If the patient is unconscious, he may acupuncture or use a fingernail to lick the patient's middling (located at the mid-1/3 junction between the nasolabial fold), Neiguan (about 5 cm above the inside of the wrist), and Hegu points (both tigers), etc., prompting the patient to wake up. If vomiting occurs, the head should be biased to the side to avoid vomiting into the trachea and causing asphyxia.
5 to the hospital. For those patients with high fever who are not regressing or who have snoring, they should be sent to the hospital as soon as possible, while actively performing the above treatment.
(2) Rescue for those who suffer from excessive fatigue. If you are in a hot and humid environment with a large number of active and over-fatigue patients, you should bring the patient to a cool, well-ventilated place to lie down, release the collar and belt, and keep the air unblocked. Use a cold towel to wet the forehead and neck. can. For coma patients, acupuncture or fingernails can be used to scramble the patient's Acupuncture Point, Neiguan Point and Hegu Point to urge the patient to wake up, and then give plenty of refreshing drinks and sugar water to supplement sweating. Loss of body fluids.
Heat stroke emergency should pay special attention to matters:
(1) When artificially cooling a person with a long duration of heat stroke in a hot environment, the time should not be too long, as long as the patient's body temperature drops and wakes up.
(2) For the relief of heat stroke caused by excessive fatigue, when cooling, use a cold towel to wet the forehead and neck, and do not give other cooling treatment to avoid worsening the symptoms.
(3) After being rescued, the awake patient must fully rest in a cool, ventilated place, and drink plenty of sugar water to supplement the loss of body fluids.
