The hot weather lasted for many days, and the number of emergency patients with cerebrovascular disease in the Neurology of Xuanwu Hospital increased. Zhao Wenbo, a neurologist, reminded that high-risk people should remain vigilant and seek medical advice in time if symptoms occur; Patients with a medical history who interrupt medication at this time have a much higher risk of developing the disease than usual, so it is more important to pay attention to regular medication. At 9:30 am yesterday, the reporter saw in front of the emergency building of Xuanwu Hospital that emergency vehicles were coming from time to time. The attending doctor told the reporter, "In recent days, the number of patients with sudden cerebrovascular emergencies has increased due to the high temperature." "It is important to take medication regularly and continue to recover." In the ward of the stroke rescue center, Zhao Wenbo is instructing Mr. Zheng, who is about to be discharged. Mr. Zheng is in his 60s and has a history of mild cerebral infarction. On the first day of the Dragon Boat Festival holiday, when his children came home for dinner, Mr. Zheng was happy and spent the whole day shopping and cooking. At night, after the children went home separately, he suddenly noticed that there was an obstacle in the movement of his upper and lower limbs. "In fact, after the last attack, the patient's blood pressure, blood sugar and blood lipids were well controlled. However, due to the stenosis of the middle cerebral artery and poor vascular conditions, after sweating and dehydration in summer heat, Hypovolemia was reduced and the blood supply to the brain was insufficient, resulting in cerebral infarction." Fortunately, Mr. Zheng, who had a medical history, was more sensitive to his own physical state and went to see a doctor in time. The emergency team of Xuanwu Hospital conducted a comprehensive evaluation and arranged targeted treatment, and his condition quickly improved. Zhao Wenbo introduced that during the Dragon Boat Festival holiday, for three consecutive hot days, the Neurology of Xuanwu Hospital received an average of more than 120 emergency patients every day, including about 20 patients with cerebrovascular emergencies. "This proportion is one quarter higher than that before the arrival of hot days." He reminded that high temperature days lead to a large loss of body fluid, which is likely to lead to cerebrovascular emergencies. Therefore, first of all, drink more water to ensure adequate fluid supply. In hot environments, it is important to avoid repeatedly entering and exiting air-conditioned rooms with low temperatures to prevent sudden contraction of dilated blood vessels, which can lead to the progression of infarction. For people with a medical history, it is important to pay special attention to regular medication during hot weather. "At this time, the blood is in a concentrated state, which is prone to the formation of blood clots. The risk of disease caused by interrupting medication is much higher than usual." In addition, the elderly and high-risk individuals with multiple underlying diseases should always be vigilant for cerebrovascular emergencies. If relevant symptoms occur, they should seek medical attention in a nearby stroke center in a timely manner, To avoid delaying the optimal treatment timing. (Reporter Sun Leqi)
