2. Mild heatstroke: the above symptoms are aggravated, the body temperature is above 38℃, facial flushing is pale, sweating, the skin is wet and cold, the pulse is weak, the heart rate is fast, the blood pressure drops, respiratory and circulatory failure and other symptoms and signs.
3. Severe heatstroke:
(l) Heatstroke and high fever: dysfunction of the thermoregulatory center, difficulty in heat dissipation and excessive heat accumulation in the body. At first, I had symptoms of threatened heatstroke, and then I had headache, anxiety, lethargy and even coma. Flushing face and dry skin. Blood pressure drops, shortness of breath, and heart rate increases. The body temperature is above 40℃.
(2) heatstroke failure: water and salt are lost due to excessive sweating, and blood volume is insufficient. The clinical manifestations are pale face, cold skin, weak pulse, low blood pressure, shortness of breath, unconsciousness, low axillary temperature and anal temperature of about 38.5℃.
(3) heatstroke spasm: After sweating a lot, you only drink plenty of water and don't supplement salt, so the blood sodium and chlorine are reduced, and the blood potassium can also be reduced. The patient is thirsty and has little urine. Muscle spasm and pain, normal body temperature.
(4) Heatstroke: Due to the strong sunlight in the head, a large amount of ultraviolet rays enter the skull, which raises the intracranial temperature (up to 465,438+0 ~ 42℃), resulting in edema and congestion of the brain and meninges. Therefore, there will be severe headache, dizziness, nausea, vomiting, tinnitus, dizziness, irritability, disturbance of consciousness and severe convulsions and coma. The body temperature can be slightly raised. The above situations can sometimes appear in combination.
