At 11:00 a.m., a 28-year-old courier brother in Beijing Anzhen Hospital ward complex first floor hall suddenly collapsed whistle heart stop, by medical staff scrambled to save the life of the courier brother in a timely manner, fortunately turned to safety. In recent years, sudden deaths have been reported repeatedly, although there is no clear statistics, but it does feel that in recent years, the proportion of sudden deaths, young people in the gradual increase in the proportion of young people, there is a clear upward trend. “Death from overwork” has become a sword of Damocles hanging over the heads of urbanites. The increasingly fierce social competition, fast pace, high pressure, overwork, unhealthy lifestyle are the invisible killers of life. What is sudden death? What diseases can cause sudden death? Sudden death is defined by the World Health Organization as death within 6 hours after the onset of acute symptoms. There are cardiac and non-cardiac causes of sudden death, of which sudden cardiac death (SCD) is the most common, defined as the sudden and irreversible termination of all biological functions, accounting for more than 80% of cases, and most often occurring within one hour. Coronary artery disease, aortic coarctation, severe heart failure, obstructive hypertrophic cardiomyopathy, fulminant myocarditis, and hereditary arrhythmias are all possible causes of sudden death, with coronary artery disease and acute myocardial infarction being the most common, accounting for more than 30% of cases.The highest incidence of SCD occurs on Mondays, with a peak between 6:00 a.m. and noon, and the highest incidence occurs during the winter months when the patient dies within one hour of onset of the event.1 Sudden death from non-cardiac causes is defined as the sudden irreversible termination of all biological functions, accounting for more than 80% of cases. Sudden death from non-cardiac causes is commonly associated with cerebral hemorrhage, pulmonary embolism, and asthma. What is the process of sudden cardiac death? Are there warning signs? Sudden cardiac death is categorized into four periods, i.e. prodromal period, terminal event period, cardiac arrest and biological death. 1. Prodromal phase: Although there are no clear warning signs, there are some clues that are overlooked because they are not specific. More than 50% of cardiac arrest days ~ 1 month before the early warning signals will be issued, chest pain is the most common about 56%, shortness of breath 13%, 4% for dizziness, fainting or palpitations. If there is chest tightness and chest pain, left shoulder and back pain, breathlessness, panic and palpitations, fainting, as well as epigastric distension, nausea and vomiting, throat tightness and pain, toothache, jaw pain and discomfort, and other atypical symptoms, it is necessary to consult a doctor in a timely manner. 2, the terminal event period: cardiovascular acute changes to the time before cardiac arrest, usually within 1 hour. The performance of chest pain, arrhythmia, palpitations, hypotension, difficulty in breathing and dizziness. 3.Cardiac arrest: It occurs suddenly, the heart loses effective mechanical contraction and pumping function. It is characterized by sudden loss of consciousness, convulsions, cessation of whistling or sigh-like whistling, and incontinence of urine and feces. When cardiac arrest occurs outside of the hospital, timely chest compressions and whooping 120 are the keys to successful treatment. Most of the sudden cardiac deaths reported as successful in the media refer to this period, which technically should be called sudden cardiac arrest, but it is easier for the public to understand when talking about sudden death. This was the case of the courier boy at Anzhen Hospital, who was fortunate to receive timely treatment and did not progress to biological death. 4, biological death: irreversible brain damage occurs within 4 to 6 minutes after cardiac arrest. After cardiac arrest without timely cardiopulmonary resuscitation or failure of cardiopulmonary resuscitation, the transition to biological death after a few minutes to a few weeks. Can sudden death be prevented? What should I pay attention to in my working life? 1, the pace of life is getting faster and faster, and the pressure is getting higher and higher. Everyone wants to stand out from the fierce competition, working overtime and staying up late has become the norm, and the ducks and pears are huge! High work pressure and lack of sleep will increase the risk of sudden death. Feeling tired for a long time, stop to rest and relax. Don’t take yourself too seriously, the earth away from who all according to turn, but the family lost you, is a permanent pain. 2, excessive drinking kills people! Some of the nature of the work decided to socialize more, drink after the hi song, crisis. Excessive drinking induces acute hemorrhagic necrotizing pancreatitis; excitement and agitation when drinking, elevated blood pressure, induced cerebral hemorrhage, acute myocardial infarction and other serious cardiovascular diseases. Although the wine is good, do not be greedy. If you can’t drink, don’t drink, and if you can drink less, don’t drink more. 3.Unhealthy eating habits. Trouble comes out of the mouth, disease enters by the mouth! Long-term high-calorie, high-salt, high-fat diet, high blood pressure, high blood fat, diabetes and coronary heart disease will quietly find you, unknowingly buried in the body time bomb. Light diet, eat fish in moderation, eat less beef, lamb and pork, eat more soy products and fresh fruits and vegetables, a small handful of nuts every day. 4, don’t take colds seriously! Colds are commonplace diseases, but the cold virus will invade the heart muscle caused by myocarditis, causing serious arrhythmia, heart failure leading to sudden death cases are not a few. After 1~3 weeks after the cold palpitations, chest tightness and chest pain, difficulty in breathing, swelling or fainting must see the cardiology department. 5, snoring should not be ignored! Snoring is medically known as sleep apnea syndrome, which greatly increases the chances of hypertension, diabetes and coronary heart disease, thus inducing sudden death. Attention to weight loss and weight control, snoring is also a disease, to timely medical care. 6, do not underestimate the ordinary constipation, hard to defecate when elevated blood pressure, induced cerebral hemorrhage and acute myocardial infarction. More exercise, eat more fiber-rich fresh fruits and vegetables, eat less stimulating food. Difficulty in bowel movement can be treated with localized corkscrew and medication under the guidance of a doctor if necessary. Do not use too much force to avoid accidents. 7, pay attention to temperature changes! In the alternation of fall and winter and summer and fall, the temperature drops, the blood pressure of hypertensive patients fluctuates greatly, and the incidence of critical illnesses such as myocardial infarction, stroke and aortic dissection increases. Cold weather, snowy weather, and respiratory infections in winter are all contributing factors to heart disease, and the risk of sudden death is significantly higher. Measure your blood pressure two to three times a week during the change of seasons, and consult a doctor promptly if your blood pressure rises or if you experience dizziness, headache, or chest tightness. Avoid outdoor activities in sub-zero temperatures and snowy days, and pay attention to keeping warm. Strenuous exercise, sauna, full meals; smoking, drug use, hey sports, as well as anger, depression, anxiety and fear and other bad emotions can induce sudden death. According to statistics, fans watching the World Cup cardiac emergencies increased 2 to 3 times, the peak is 2 hours after the start of the game. Duke University study found that the stock market crash, the incidence of myocardial infarction increased significantly. Cardiovascular disease patients and high-risk groups to stay away from the stock market and intense ball games. Heart disease patients should pay attention to the regular review of indicators, strictly follow the doctor’s instructions for medication. Regular medical checkups for healthy people can help detect health problems at an early stage and prevent them from occurring in the first place. A healthy lifestyle with a balanced diet, moderate exercise, a calm mindset, and abstinence from smoking and alcohol can not only prevent sudden death, but also prevent chronic diseases such as cancer. How to deal with sudden deaths around you? Courier brother is unfortunate and fortunate! Luckily it happened in the hospital, lucky to get timely treatment by cardiologists. Cardiac arrest for more than 4 to 6 minutes, permanent damage to brain tissue occurs, more than 10 minutes will be brain dead! And with ambulances unlikely to arrive in time, the person found at the scene becomes the key to saving lives. Everyone should learn first aid techniques that will save lives at critical moments. The first 4 minutes after cardiac arrest is the golden time for resuscitation! The earlier the resuscitation, the higher the success rate and the fewer the sequelae. For every minute of delay, the success rate decreases by 10%. If someone suddenly collapses, loses consciousness, stops breathing or wheezes, do not take him/her to the hospital, but resuscitate him/her immediately! Step 1: If there is only one person, first call the emergency number 120 or 999, briefly explain the situation and the location. If someone else is present, ask them to call the emergency number. Step 2: Immediately apply chest compressions. Kneeling on the side of the patient’s hands overlap, the root of the palm of the hand is placed in the center of the chest at the midpoint of the double nipple line continuous force rapid vertical pressure, frequency of 100 times per minute or more, the amplitude of the pressure at least 125px. without CPR training can only press, do not have to blow, insist until the arrival of professional emergency personnel. Step 3: Lift the jaw and tilt the head back to open the airway. Step 4: If there is an external automated defibrillator (AED) in the place of occurrence, after chest compressions, immediately cooperate with the use of the AED, and operate according to the voice prompts to improve the success rate of resuscitation. In 2013, the media reported a sudden death incident on a bus in Fujian. Through checking the surveillance video to understand that in the man unconscious 17 minutes, only one person went up to pinch his human middle. Reporters interviewed 10 bus drivers, all said they did not know first aid. Mastering the simple and easy chest heart compression techniques can save lives at critical moments. Europe and the United States will be CPR first aid training into the compulsory courses for primary and secondary school students, cardiac arrest resuscitation success rate is much higher than our country. Actively promote a healthy lifestyle at the same time, universal popularization of first aid education, public places to configure AED, in order to fundamentally improve the success rate of rescue, to save lives!
