heat stroke and high fever
Introduction
Introduction Under the control of the hypothalamic thermoregulatory center, the body temperature of normal people is in a dynamic equilibrium, which is maintained at around 37 °C. Human basal metabolism, various activities, physical labor and exercise rely on the catalysis of sugar and fat to supply heat. The heat is transmitted through radiation, conduction, convection, and other functions such as skin vasodilation, blood flow acceleration, perspiration, respiration, and excretion. The evaporation method is distributed. In an environment with high temperature and high humidity, especially in the case of weak or heavy physical labor, if heat is blocked and heat is accumulated, heat stroke is likely to occur.
Cause
Cause
The ambient temperature is too high:
The human body receives heat from the external environment, and in the environment with elevated atmospheric temperature (>32 °C), high humidity (>60%) and no wind, long-term work or strong physical labor, and lack of adequate heatstroke prevention measures, lack of Heatstroke is prone to heatstroke.
Increased body heat production:
Such as heavy physical labor, fever, hyperthyroidism and the application of certain drugs (amphetamine), these factors can lead to heat stroke disease.
Heat dissipation barrier:
Such as high humidity, obesity or poor ventilation.
Sweat gland dysfunction:
Found in patients with systemic sclerosis, extensive skin burns, scar formation or congenital sweat gland deficiency.
Examine
an examination
Related inspection
Blood routine blood electrolyte examination blood test urine routine
1, physical examination: the examination should be detailed and comprehensive, combined with medical history and symptoms, and then in-depth examination.
2, laboratory inspection: first for general inspection, according to the general screening results, then decide to further check the project, try to avoid the purposeless "casting" type inspection.
3. X-ray and other inspections.
Diagnosis
Differential diagnosis
1. According to the high temperature environment and clinical manifestations at the time of onset.
2, should be identified with summer infection, febrile diseases, such as epidemic encephalitis, meningitis, cerebral malaria.
3, and other reasons for this coma and cerebrovascular accident identification.
4, heat stroke caused by abdominal pain need to be identified with acute abdomen.
