Heatstroke refers to an acute disease characterized by dysfunction of central nervous system and/or cardiovascular system due to dysfunction of thermoregulation center or sweat gland and excessive loss of water and electrolyte in high temperature or high humidity and closed environment. In recent years, the global climate has gradually warmed, and the incidence and mortality of heatstroke have increased.
This paper introduces its epidemiology from three aspects: time, susceptible population and regional distribution. There are outbreaks of heatstroke all over the world. China's tropical and subtropical areas are relatively large, the degree of urbanization is getting higher and higher, and the urban population is becoming increasingly dense, resulting in the "urban heat island effect", and the incidence of heatstroke among urban residents is gradually increasing.
After being exposed to high temperature for a long time, symptoms such as headache, dizziness, thirst, sweating, etc. appear, and the body temperature is normal or slightly elevated at first. When the core body temperature continues to rise above 38 degrees Celsius, in addition to the above symptoms, there will be flushing, sweating, burning skin, chills in limbs and so on.
If not intervened in time, it can gradually develop into coma with limb convulsions, and in severe cases, it can produce multiple organ failure.
Severe heatstroke includes heat spasm, heat exhaustion and heatstroke. Heat spasm is 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 is 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. Heatstroke can be divided into two types: labor heatstroke and non-labor heatstroke.
Occupational heatstroke is more common in healthy young people (such as sports participants and officers and men in training). It is characterized by long-term exposure to high temperature, high humidity and windless environment, and after a period of high-intensity 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.
