In the past few days, the sudden death of Dr. Lu Jingning, a doctor of hepatobiliary surgery at the First Affiliated Hospital of Guangxi Medical University, has exploded the circle of friends of healthcare workers, 37 years old, medical doctor, father of 2 children. These key words instantly burst the tip of each of our hearts, suddenly left his colleagues, his teachers, his patients, his parents, his wife and children. Dr. Lu’s sudden departure leaves those around him with endless grief and reflection. It also left his peers to reflect on how to cope with sudden death. Let’s recognize the definition of sudden death. Definition of Sudden Death (WTO version): Sudden death is defined as the sudden death of a patient who is or appears to be in good health and who dies suddenly of a natural disease within an unexpectedly short period of time. Analyzing the characteristics of this definition, in unhealthy patients, uncertain time, due to disease suddenly died. It is currently recognized that those who die within 1 hour of the onset of the disease mostly die of sudden cardiac death. Cardiac diseases account for more than 80% of all causes of sudden death, especially coronary heart disease and various unknown arrhythmias. The famous writer Bi Shumin with a work, called “appointment death” had this paragraph: we as a nation do not like to discuss the death of ordinary people. We honor the heroic death, the tragic death, the chaste death, the suffering death, and we despise the ordinary death. No doubt we are not afraid of death, but we are afraid of dying in a wimpy way, afraid of dying without a choice, before we have said goodbye to our dear ones. While we have not yet accepted how to face death, we have been forced to face sudden death, the sudden kind of death. If we have to say that there is any meaning between life and death, it must be that we can choose to live or die with dignity. And sudden death is the kind we don’t make a good choice about. In fact, sudden death is the third leading cause of death among young people, the first being suicide and the second being accidents. Some data show that there are more than 600,000 sudden deaths in China every year. When you have gone through a lot of hard work, over the Everest, thought the bitter sweet, talk about life, you can never predict: sudden death let your life come to an abrupt end. When you think you are going to make it big, the next second comes the end of your life. Although the incidence of coronary heart disease is getting younger, there are still not many young people with coronary heart disease, and there are data showing that the majority of sudden deaths in young people are due to a variety of unknown cardiac arrhythmias. Most sudden deaths are preceded by an aura, and as the saying goes, there is no such thing as love or hate without a cause. Most of the aura of sudden death manifests itself in the form of frequent chest tightness, panic attacks, shortness of breath, and even fainting, and in some cases, easy fatigue, stomach pain, and so on. More often than not, the symptoms are not directed and are not easy to take seriously. Regarding the sudden death in places outside the hospital after the success rate of CPR in the country is less than 3%, you can brainstorm once the sudden death almost means death. Causes of sudden death: stress, depression, overwork, heavy smoking, alcohol abuse, of which exertion is the most important cause of sudden cardiac death. Of course, there are other causes of sudden death for which there is no evidence of disease at all.
