With the onslaught of heat, sweating, dehydration and viscous blood, as well as improper use of air conditioning, patients with underlying diseases such as hypertension, hyperlipidemia and diabetes are prone to stroke and should be vigilant. Lack of water in the body increases the risk of stroke In many people’s view, the cold winter is the high incidence of stroke (stroke) season, summer is fine, but in fact, it is not. In the hot summer, people with high blood pressure, high blood cholesterol, diabetes and other high risk of cardiovascular accidents are not safe, and strokes still “follow”. Neurologists warn that the incidence of stroke can be increased by sweating, lack of water, sticky blood, and improper use of air conditioning in summer. Studies have shown that when the temperature exceeds 32°C, the incidence of stroke is 66% higher than usual, and the risk increases as the temperature rises. In summer, the human body sweats more, the body’s internal environment is prone to water shortage, increasing the viscosity of the blood, which can increase the formation of blood clots and even the incidence of stroke for people suffering from hypertension, hyperlipidemia or underlying diseases such as cardiovascular disease. In addition, in clinical practice, experts also found that many patients have strokes related to the improper use of air conditioning. The use of air conditioning in the summer to avoid the heat is common, the temperature difference between indoor and outdoor is too large for the elderly, as well as hypertension, arteriosclerosis patients, is a very difficult to control external factors. Because of the sudden cold and hot temperature changes will make the cerebral blood vessels repeatedly contraction diastole, resulting in cerebral blood circulation disorders, leading to cerebral infarction in serious cases. First Aid for Sudden Stroke Remember the Trilogy Stroke is divided into two kinds of cerebral infarction and cerebral hemorrhage, of which cerebral infarction accounts for 60%-80%. Cerebral infarction (ischemic stroke) is caused by narrowing of cerebral blood vessels, thrombosis or blockage of blood vessels by emboli brought along with blood flow, which makes blood flow blocked. Domestic and foreign treatment guidelines recommend that for patients who are eligible for thrombolysis within 3 hours of the onset of cerebral infarction, intravenous thrombolysis should be given as soon as possible to dissolve the thrombus and reopen the occluded cerebral vessels, thus reducing the disability and mortality rates. After the occurrence of stroke, rescue is equal to life, therefore, wind first aid should remember the three steps: Step 1: detect abnormalities When stroke patients have stroke, they will have numbness and weakness of one limb, numbness of one side of the face, distorted corners of the mouth, or blurred vision, headache and other discomforts. In fact, it is not difficult to identify a stroke, as long as family members or people around you have any one of the following three symptoms, we should send them to the hospital without delay Say a word: ask the patient to repeat a phrase, if his or her speech is slurred or unable to speak is abnormal; smile: ask the patient to “show teeth” or smile, if his or her face is asymmetrical on both sides (one side If the corners of the mouth are crooked, it is abnormal. Hands flat: Ask the patient to close his eyes and hold his arms flat for 10 seconds. If one arm cannot be held flat and falls down, it is abnormal. It can be summarized as a stroke treatment mantra, namely, “the corner of the mouth is crooked when the speech is slurred, and the arm is not lifted to the hospital”. Step 2: Call “120” Once a family member is found to have had a stroke, the family should immediately call “120” and record the time of the attack. While waiting for the ambulance to arrive, do not move the patient, especially avoid shaking his or her head. Try to keep the patient in a side-lying position or with the head tilted to one side to keep the airway open, and remove dentures if they are present. Many families with elderly people are equipped with “Angong Niuhuang Pills”, and after an elderly person has a stroke, many people usually call “120” while feeding the patient medication. Taking any medication before being sent to the hospital will only increase the risk of death, as it can lead to choking by accidental inhalation. Therefore, do not give medication or water to a stroke patient. Step 3: Try to send the patient to a hospital with thrombolytic capability. Hospitals with rich experience in thrombolysis often have green channels and stroke teams. After the patient is admitted, the doctor will make a quick diagnosis and immediately perform an emergency CT scan to ensure that the examination is completed as quickly as possible.
