case study

Sudden deaths occurred one after another.

Continuous high temperature in summer is one of the causes of sudden death. In late June this year, 53-year-old Hubei female worker Zhu died suddenly while taking a nap in a luggage factory in Quanzhou Industrial Zone. The reporter learned from the border police station in Fushan, quanzhou taiwanese investment zone that on July 26th, a 72-year-old grandmother in Dongyuan Town fainted while going to the toilet and died after being rescued. The doctor judged that grandma died suddenly.

On July 28th, Huang, a Malaysian national men's basketball player who was preparing with the team in Jinjiang, sat on the court and watched the game. Suddenly, he fainted and was sent to the hospital for rescue and died. The cause of death was sudden cardiac death. Born in 1988, I am only 25 years old this year.

Wake up

Watch for signs of chest pain and fatigue.

Wang, deputy director of the emergency department of the Second Affiliated Hospital of Fujian Medical University and chief physician of cardiovascular medicine, said that sudden death is an unexpected and sudden death, which mostly occurs in patients with cardiovascular and cerebrovascular diseases. Sudden death is easy to occur in hot weather because it is easy to cause telangiectasia of human skin epidermis, reduce blood supply to internal organs and increase the risk of sudden death; High temperature can also cause a lot of sweating. If body fluids are not replenished in time, the viscosity of human blood will increase, causing sudden cardiovascular diseases.

Dr. Chen from the emergency department of the First Hospital of the city introduced that after the summer, the number of patients with sudden myocardial infarction increased, and most of them were elderly people. Sudden death itself is difficult to predict, but most of them have some signs before they happen. The most common manifestations are chest tightness, chest pain, weakness of limbs, cold sweat and dizziness. If the citizens themselves are high-risk groups and have related symptoms, they must go to the hospital in time to eliminate hidden dangers.

Take the medicine and have a rest.

"Patients with cardiovascular diseases must take medicine on time in summer, and they can't increase or decrease their own drugs or stop using them." Wang said that patients with cardiovascular diseases such as coronary heart disease should carry nitroglycerin and quick-acting jiuxin pills with them when they go out, and try to carry emergency cards with home address, family contact number and medical history to prevent accidents.

It is reported that in some cases of sudden death of young people, some people have no symptoms before onset. They may be recessive patients with cardiovascular disease. Because I didn't have a physical examination in time, I didn't notice symptoms such as mild chest tightness, which led to sudden death. Regular physical examination is an effective way to find hidden dangers.

Dr. Chen, the emergency department of the First Hospital of the City, reminded that the weather is hot in summer, and middle-aged and elderly people should pay special attention to rest and not exercise vigorously in a sultry environment. Pay attention to a low-fat and low-oil diet and replenish water in time. Young people should avoid long-term fatigue and mental stress, quit smoking and limit alcohol, and maintain good living habits. If there are sub-health signals such as insomnia, anxiety and irritability, memory loss and inattention, we must adjust the pace of work and life as soon as possible to ensure adequate rest time.

Emergency cardiac compression with artificial respiration

It is reported that the clinical features of sudden death are cardiac arrest, respiratory arrest, loss of consciousness, disappearance of arterial pulsation and failure to measure blood pressure. Sudden death occurs suddenly, often only for a few minutes or ten minutes. Therefore, after sudden death, how to emergency rescue becomes particularly important.

How to give first aid when someone has symptoms of respiratory or cardiac arrest? Wang pointed out that we should call 120 immediately. While waiting for the ambulance to arrive, let the patient lie flat, lift his neck, and then raise his head to promote airway patency. Effective cardiac compression, the specific method is to lock hands and palms, raise palms and place them under the patient's sternum 1/3, and press vertically, the frequency is 100 times per minute, the amplitude is greater than 5cm, and the force is even and gentle; At the same time, artificial respiration is used, holding the patient's nostril with one hand, pushing the jaw open, inhaling hard and blowing into the patient's mouth. Every 30 cardiac compressions are supplemented by two artificial breaths.

Drink water when you are thirsty. Eight cups a day will help you keep healthy.

(Reporter Wu Zhiming) With the arrival of high temperature, people are sweating more and drinking water has become an important "health class" in summer. Experts say that drinking water is also particular.

Zhu, director of Fujian Training Department, a nutrition and health care teacher in china health care association, said that hydration should be done step by step, and drinking too fast, too much and too cold won't do. The amount of drinking water in summer is larger than that in other seasons. Generally, it is advisable to drink 1500 ml to 2000 ml (about 8 cups) every day. He said that drinking water in summer should pay attention to the following points:

Drink when you are thirsty. I only want to drink water when I am thirsty. When you are thirsty, upset, tired and have a headache, it means that the cells of your body have begun to dehydrate. At this time, drinking water again is already "passive drinking". Over time, the human body will be in a state of potential water shortage for a long time, which is not conducive to normal metabolism. Therefore, drinking water, like eating, also needs to be timed, and drinking water before feeling "thirsty".

Drink warm, not cold. Drinking cold water will suddenly cool the gastrointestinal mucosa, shrink the originally unobstructed capillaries, and cause gastrointestinal discomfort and even diarrhea. The optimum water temperature is 10℃-30℃. In addition, drink as little cold drinks as possible.

Drink slowly, but not too fast. Many people are used to "binge drinking", but it is not good for their health. Drinking plenty of water quickly will quickly dilute the blood and increase the burden on the heart; When sweating heavily in hot weather, overeating will increase sweating reflexively and further increase the loss of electrolytes such as sodium and potassium. Drink a small amount of water for many times, and the amount of each time should be controlled within 150 ml.
