In autumn and winter, the temperature drops and the temperature difference between indoor and outdoor increases. Recently, the number of cardiovascular emergency patients in Beijing has increased significantly. In the second week of November (November 7-14), Beijing Emergency Center dispatched 1730 emergency vehicles for cardiovascular disease, more than 200 more than the second week of October. Mr. Zhang, who has just retired, found himself a part-time guard. Recently, when he got up early and rode his bike to work, he suddenly felt pain and suffocation in his left shoulder. Mr. Zhang thought it was the cold weather in the morning that caused the wind, so he asked for leave to go to the nearby Chinese medicine clinic to get rid of the cold. Unexpectedly, during the diagnosis and treatment, he became more and more uncomfortable, sweating profusely and looking pale. The medical staff of the clinic called 120 hurriedly. When the first aiders arrived at the scene, Mr. Zhang had "ventricular fibrillation" and lost consciousness. First aiders rushed to use the vehicle mounted defibrillator to give first aid. Fortunately, Mr. Zhang recovered his heartbeat after receiving the first aid and was promptly transferred to a nearby hospital for further treatment. "Mr. Zhang's situation is particularly likely to occur in the early morning of cold weather." Liu Yang, the chief physician of Beijing Emergency Center, said that after heating, the temperature difference between indoor and outdoor is large, and sudden changes in body temperature are likely to bring about vasoconstriction, leading to related emergencies. Remind the elderly, especially those with hypertension, diabetes, cardiovascular disease and other related basic diseases, not to rush out. "It is recommended to" buffer "out, from home to the corridor, and then slowly from the corridor to the outside." Liu Yang introduced that the typical symptom of patients with angina pectoris or myocardial infarction is precordial pain, but there are also some patients, especially the elderly, who can show "radiation pain" such as left shoulder and arm pain, epigastric pain, toothache, and even left finger pain, which is prone to disease delay. If there is persistent or frequent pain accompanied by sweating, nausea, dizziness and other symptoms, we should be more alert to the risk of myocardial infarction. Once a similar situation occurs, it is necessary to go to the hospital for ECG examination. The first aiders remind that it is better to wear a reminder card for the elderly who have a history of acute disease or are at risk. The prompt card includes the contact information of the family members, the medical history of the elderly and the types of drugs taken. "In winter, we often encounter emergencies during outdoor activities. This prompt card will help the first aiders to rescue more specifically." November 20 is the Chinese Day of Myocardial Infarction Treatment. First aid workers hope to introduce to the public two "120" concepts that are crucial to the treatment of myocardial infarction. "One is 120 minutes: that is, the patients with myocardial infarction can get effective treatment such as opening the occluded blood vessels within 120 minutes, and the effect is the best. The other is 120 emergency call: remember to call for help at the first time when an emergency occurs." Liu Yang said. (Outlook New Times)
