Data shows that there are about 2.5 million new stroke patients in China each year, and more than 1.5 million people die from stroke (stroke). For stroke patients, time equals brain, and recognizing early stroke symptoms is crucial. The “120” mnemonic for Chinese Currently, the “fast” mnemonic (i.e. Face, Arm, Speech, Time) is used internationally as an early warning signal for determining stroke. Since this mnemonic is composed of English words, it is not easy to be understood and memorized by Chinese people. Recently, a 120-word mnemonic suitable for Chinese people to quickly recognize stroke was published in The Lancet – Neurology. That is, look at 1 face: asymmetry, crooked mouth; check 2 arms: parallel lifting, unilateral weakness; 0(listen) to speech, slurred speech, difficulty in expression. When you find these problems, be the first to suspect a stroke and go to the hospital in time. Look at 1 face. As the brain nerves control the muscles of the face, when the stroke first begins, the nerves are damaged, affecting muscle function, and more than 90% of patients will have a crooked mouth and asymmetrical face. Check 2 arms. Stroke usually involves only one of the two brain hemispheres. Therefore, the patient will suddenly experience weakness and numbness on one side of the limb, and when both arms are lifted in parallel, one of them will droop. 0 (Listening) to speech. When the blood supply to the brain is insufficient, the nerves that govern the movement of the tongue malfunction, and one of the common symptoms is a sudden inability to speak or slurring of words, or even the inability to speak. Call the “120” emergency number immediately When you notice the early symptoms of a suspected stroke, keep the patient quiet and avoid mental stress. At the same time, the patient or family members should immediately call 120 and send the patient to the hospital for treatment. If the family does not know anything about stroke, they should be cautious about taking the patient to the hospital on their own. First of all, randomly moving the patient or the patient walks around on his/her own will increase the risk of secondary injuries such as falls and fractures. By calling an ambulance through “120”, the doctor can also conduct a preliminary diagnosis and treatment during the transportation of the patient and contact the hospital where the patient is going to be transported. Secondly, many people do not know the hospital situation and decide to go to a hospital that may not have the capacity to treat a brain attack, and even if they do have the capacity, the hospital may not have the staff, equipment and beds in place, which may delay the treatment. The significance of calling the emergency number is that the hospital can quickly start a targeted emergency green channel to save time. Finally, many people believe that headache is a typical symptom of stroke, which is not a complete statement. Commonly speaking, stroke is divided into two categories: cerebral hemorrhage and cerebral infarction. Cerebral infarction is a blockage of cerebral blood vessels, light cerebral infarction has no headache symptoms, unless there is a large blockage, resulting in cerebral edema, may have a headache, of course, this is a few days later. Cerebral hemorrhage, on the other hand, refers to the rupture of a cerebral blood vessel. When bleeding irritates the meninges or the formation of a hematoma causes an increase in intracranial pressure, only then will there be an obvious headache. Therefore, don’t assume that the absence of a headache is not a stroke. 3~6am is the high-risk time 3~6am is the most dangerous time for high incidence of stroke. This is related to a number of factors. As the human body has a biological clock and other self-regulating mechanisms, evening rest, relative to the daytime, the body’s metabolism is low, blood vessel relaxation, blood flow is also slow, the formation of thrombus base. Early in the morning, the secretion of vasoactive substances increases, blood pressure rises, aggravating the cerebrovascular load. Coupled with the fact that there is no water supplementation in the evening, but also due to metabolism leading to water loss, higher blood viscosity, all factors increase the risk of stroke.
