中暑是在高温环境或太阳直接照射下,由于体温调节障碍而发生的一种内科急症。尤以气温骤升、温度高而又通风不良时容易发生。 病理生理 在高温环境下,体内热积蓄过多,体温升高,如超过了体温调节中枢的调节能力,则体热不能散发而骤升至41～43℃,病人将发生中暑高热;或由于大量出汗而引起脱水、电解质紊乱和酸中毒,亦可由于 Heat stroke is a medical emergency occurring due to the disturbance of thermoregulation under high temperature environment or direct sunlight. Especially in the sudden temperature rise, high temperature and poor ventilation occurs easily. Pathophysiology In high-temperature environment, excessive accumulation of heat in the body, body temperature, such as over the regulatory capacity of the thermoregulatory center, the body heat can not be emitted and suddenly rose to 41 ~ 43 ℃, the patient will have heat stroke; or due to a large number Sweating caused dehydration, electrolyte imbalance and acidosis, but also due to
