Heatstroke refers to a group of clinical symptoms caused by long-term exposure to high temperature or physical activity in hot environment, which are characterized by high fever, dry skin and central nervous system symptoms. The core temperature of 465438 0℃ is an indication of serious adverse prognosis. The death rate of severe heatstroke with body temperature above 40℃ is 4 1.7%, and the death rate above 42℃ is 8 1.3%.

Common etiology

Workshop work at high temperature is caused by direct sunlight, crowded and concentrated crowds and difficulty in heat dissipation.

common symptom

Thirst, loss of appetite, headache, dizziness, excessive sweating and heatstroke are diseases characterized by dysfunction of thermoregulation center, sweat gland failure and excessive loss of water and electrolyte in hot weather and high humidity and windless environment. According to the different pathogenesis and clinical manifestations, heatstroke is usually divided into heat spasm.

Heat exhaustion and heatstroke (heatstroke). The clinical manifestations are headache, dizziness, thirst, hyperhidrosis, weakness and pain of limbs, inattention, uncoordinated movements and other symptoms.

Heatstroke refers to the symptoms of disorder of body temperature regulation, disorder of water and electrolyte metabolism and impairment of nervous system function under the long-term effect of high temperature and thermal radiation. Patients with brain diseases, the elderly and the infirm, and women with poor heat tolerance are particularly prone to heatstroke. Heatstroke is a life-threatening emergency. If it is not treated quickly and forcefully, it will cause convulsions and even death.

Permanent brain injury or renal failure. The core temperature of 465438 0℃ is a sign of serious prognosis. A slight increase in body temperature often leads to death. Old age, weakness and alcoholism can aggravate the prognosis.
