　　 After the Shencheng fell into the abbot, the temperature exceeded 30℃. Although it has not yet entered the real high temperature season, the outpatient and emergency departments of major hospitals have already opened quietly. The reporter learned from many hospitals in Shanghai this morning that recently, patients with gastroenteritis, colds and fevers have increased. The elderly suffer from cardiovascular and cerebrovascular diseases. Children have become the main force in medical treatment. ". Experts said that in hot weather, it is necessary to prevent cardiovascular and cerebrovascular diseases, use air conditioners scientifically and appropriately, and pay attention to food hygiene.

　　 Be wary of cardio-cerebrovascular diseases in high temperature
　　 Under high temperature environment, the body's metabolism speeds up, the heart load increases, the heart rate increases, and the oxygen consumption increases. Coupled with sweating and heat dissipation, there is a lot of water loss, blood viscosity increases, and it is easy to block the cardiovascular and cerebrovascular vessels. In severe cases, it can cause cerebral thrombosis or myocardial infarction. In the past few days, the emergency department of the tenth hospital has received some elderly people who have come to see them because of "chest pain" and "heart discomfort".
　　 Dr. Peng Hu, deputy director of the emergency department of the hospital, said that in hot weather, skin blood vessels will expand in order to dissipate heat, and the proportion of body blood distributed to skin tissues will increase significantly compared with normal temperature weather. On the other hand, heat dissipation in summer is mainly through sweating and evaporation of water, and body fluids are lost invisibly, especially in the elderly. The body is often slow to perceive and respond. If the body is not hydrated in time or insufficient, the blood will be concentrated, increasing and shrinking, resulting in blood volume. Decrease, blood flow slows, and some patients stay up late, fatigue, catch cold, etc., which can easily lead to thrombotic diseases. Not long ago, there was a male patient in Hangzhou sweating profusely after exercising and blowing on the air conditioner, and failed to replenish water in time, leading to a stroke.
　　 Peng Hu reminded that young and middle-aged people should not be taken lightly. Many people have the habit of smoking and drinking. Chemicals in cigarettes can cause vasoconstriction, hardening, and stenosis. Clinically, it is not uncommon to have cerebral infarction and myocardial infarction at the age of 30 or 40.
　　 In the hot summer, the blood pressure of some patients is lower than that of other seasons. Many patients with mild hypertension can drop to normal blood pressure in the summer. Experts say that once the medication is stopped or reduced, it is easy to cause disease. Drugs should be adjusted under the guidance of professional doctors, and the disease should not be blindly "autonomous".
　　 Increased diarrhea in summer, or related to food hygiene
　　 Recently, Liqun Hospital in Putuo District admitted to a patient with intestinal disease. He has had diarrhea for 3 days and may have eaten the overnight vegetables at home. Dang Zongyan, deputy director of the Emergency Medicine Department of Liqun Hospital, said that unpreserved food in summer is most likely to cause bacterial infections. The first symptom of patients is diarrhea. Especially the elderly are more sensitive to dehydration and are more likely to cause shock and liver and kidney failure.

　　 In the emergency department of Liqun Hospital, the number of people suffering from acute gastroenteritis has increased recently. "These symptoms are mostly related to unsanitary diet." According to Dang Zongyan, bacteria multiply fast in summer and food is prone to spoilage. Leftovers are kept in the refrigerator for too long, not cleaned in time or not heated enough, which will cause bacteria and viruses to enter. The gastrointestinal tract induces disease. Dang Zongyan said that the simplest way to sterilize is to clean and fully cook. Summer is the season for high incidence of digestive tract diseases. Citizens should order less takeaways and eat less overnight dishes. The cold drinks and fruits in the refrigerator should be kept separately to prevent cross-infection of bacteria; if you are not careful, you should go to the hospital in time. , Replenish water and electrolytes in time.
　　 Many children with fever are caused by air conditioning
　　 Children with weaker constitutions are also prone to respiratory infections that cause fever, accompanied by coughing, sneezing and other symptoms. In the recent period, the daily average number of outpatient visits in the Children's Hospital of Fudan University has reached 5,000, which is an increase compared to the previous period.
　　 "Fever is accompanied by mild coughing, sneezing and other symptoms, most of which are upper respiratory tract infections." The doctor said that the respiratory tract is very fragile. Once the air-conditioning breaks the "line of defense" of the respiratory tract, cold symptoms such as coughing, sneezing, and runny nose will appear. . In addition, tightly closed doors and windows prevent dust and dust mites from circulating, and allergic reactions are prone to occur.
　　 In the pediatric clinic, there are some children who come to see you because of an asthma attack. According to the doctor, the use of air conditioners without cleaning at home in summer is also an important cause of asthma. Due to the large difference in temperature and humidity inside and outside the room, if you do not pay attention to protection when entering and leaving the air-conditioned room, this is equivalent to being stimulated by sudden changes in temperature and cold air, which may easily induce asthma. The doctor recommends that in order to prevent childhood asthma, it is necessary to develop the habit of cleaning the air-conditioning filter regularly; when entering and leaving the air-conditioned room, strengthen protection to prevent the cold air in the air-conditioned room from irritating the respiratory tract.
　　 Appointment appointment, off-peak treatment
　　 It is still in the period of epidemic prevention and control. Although the major hospitals in the city have returned to normal, the string of epidemic prevention cannot be relaxed. At the Huashan Hospital affiliated to Fudan University, the reporter saw that entering the outpatient hall must pass through the serpentine queuing area and show the application code. During the day, the morning is still the time when the number of people visiting a doctor is the largest. The hospital reminded to make an appointment before coming to the hospital for treatment, and arrange the treatment time reasonably. Before entering the hospital, prepare the application code and wear a mask.
　　 In order to effectively cope with the possible peak of visits, many hospitals have adopted a series of measures, such as adjusting the source of numbers and sending more doctors. Shen Guomei, director of the Outpatient and Emergency Management Office of the Children's Hospital, introduced that there are more children who choose to see a doctor during the summer vacation, most of which are concentrated. Specialties such as endocrinology, orthopedics, and ENT, therefore, it is also recommended that non-school-age children try not to come to the hospital for surgery during the summer peak.

　　The high temperature hits, "baking" everyone's heat resistance ability, the emergency rooms of Shanghai hospitals are experiencing a wave of small peaks, which is about 15% more than that in July. In the past few days, reporters visited the hospital and found that compared with previous years, there were fewer emergency respiratory infections this year, but there were a lot of critically ill patients observed, and gastrointestinal patients continued to increase. In addition, due to the use of air-conditioning, heatstroke patients are rarely seen in urban hospitals, but air-conditioning diseases caused by improper air-conditioning, and blood sugar bursts caused by large amounts of cola and other sugary carbonated beverages have become "seasonal restrictions in emergency rooms." disease".
　　There are a lot of elderly patients
　　"In the normalized epidemic prevention stage, the number of patients in the emergency room is relatively stable, but there are many critically ill patients, especially the elderly," said Fei Aihua, director of the emergency department of Xinhua Hospital, pointing to the "full" observation room. In hot weather, some elderly people who have underlying diseases are more difficult. Cardiovascular and cerebrovascular diseases and lung infections are common problems.
　　"Now every household in the city basically has air conditioners, and they pay more attention to the care of the elderly. Therefore, there are very few elderly people who suffer from heat stroke because of too much heat. On the contrary, they are more affected by vasoconstriction due to the cold and hot air conditioning. Get up.” Fei Aihua said, the indoor temperature is low, and the outdoor is very hot, the blood vessels dilate, and the burden on the heart increases. In summer, sweating is more frequent. The body's water evaporates through sweat, and the blood viscosity also increases. It is easy to cause ischemia or blockage of cardiovascular and cerebrovascular vessels. In severe cases, it may even cause myocardial infarction or stroke.
　　She suggested that elderly people with underlying diseases must not stop taking drugs casually, while maintaining a good mood and mentality. Always pay attention to heatstroke prevention and cooling, drink plenty of water. In addition, the temperature of the air conditioner should not be too low, it is more appropriate for the elderly to be about 8?C lower than the outdoor temperature. If you want to go out, you can turn off the air conditioner in advance to let your body adapt.
　　"Air conditioning disease" can be completely prevented
　　"The life of summer is given by air conditioning." As everyone knows, many illnesses in summer are also given by air conditioning. A few days ago, the emergency department of Huashan Hospital admitted to the patient who had "crooked mouth and unable to close one eye" due to air conditioning. Chen Mingquan, director of the emergency department, told reporters that every year he encounters such patients, many of whom are young and middle-aged. Some citizens are accustomed to staying in air-conditioned rooms for long periods of time, coupled with bad habits such as staying up late, lack of exercise, and a preference for cold drinks, resulting in decreased resistance and easy to induce facial neuritis.
　　Many netizens also complained that their spring sleepiness lasted until Xia sleepy, poor appetite, dizziness, joint pain, and exhaustion. "This situation may actually be related to air-conditioning disease." Chen Mingquan said that the "cold" stimulation of air-conditioning causes the body's blood vessels to contract, which affects the blood supply of the cardiovascular and intestinal blood vessels, which in turn induces the onset of the aforementioned diseases, especially in children and the elderly. And people with weaker resistance.
　　For the treatment of "air-conditioning disease", Fei Aihua recommends drinking plenty of warm water to avoid wind and cold. Patients with diarrhea can be treated with fluid rehydration. During the treatment, attention should be paid to electrolyte imbalance. Those with joint stiffness and pain can be treated with local hot compress, or with some mung bean soup for diet therapy. Air-conditioning-related diseases are completely preventable. It is recommended to open windows for ventilation, reasonably adjust the indoor temperature difference, and clean the air-conditioning regularly.
　　Gastrointestinal infections can be fatal
　　The reporter learned from the Municipal Children's Medical Center that the high temperature has caused an increase of more than 10% in small patients, many of which are gastrointestinal diseases such as diarrhea. The doctor said that due to high temperature and other factors, all kinds of bacteria are easy to grow and multiply, and food is very easy to spoil, and the child's gastrointestinal function is not yet mature, and the resistance is poor. Infantile diarrhea has become a common disease. If the child has diarrhea, parents should not blindly give medicine to the child. First, observe the child's stool and mental state, and treat it symptomatically. Diarrhea will lose a large amount of water and electrolytes, and it is easy for children to have symptoms such as dehydration and electrolyte balance disturbances to different degrees, so parents should take their children to see a doctor as soon as possible.
　　For ordinary adults, diarrhea may not be a major event, but for some people, it may be fatal. Not long ago, the emergency department of Xinhua Hospital received a patient with diarrhea, blood in the stool and then a perforation of the digestive tract. Fei Aihua said that this patient had a gastrointestinal tumor and was treated with fever due to infection. His condition progressed very quickly, and eventually he died. "Elderly people with underlying diseases should not be procrastinated if they are unwell, go to the hospital as soon as possible, don't take it seriously, and don't be afraid of going to the doctor, because seeing early and seeing late at night may lead to different endings." Fei Aihua reminded .
　　Drink plenty of warm white exercise, don't overdo it
　　"In summer, we advocate drinking plenty of water. It is best to drink warm plain water instead of using beverages." Fei Aihua said that last month, the hospital saw a 28-year-old man who was obese and loved to drink Coke very much. Such carbonated drinks. Drinking beverages as water for a long time will eventually lead to coma. Fei Aihua said that some people have diabetes or abnormal metabolic function, but they don't know that after drinking a lot of sugary drinks, the acute complication of diabetes, namely diabetic ketoacidosis, is caused. In fact, for ordinary people, regular or excessive consumption of sugary drinks is not good for the body. Sugary drinks can cause obesity, diabetes, fatty liver, high blood pressure, gout, dental caries, etc., and sugar reduction has become a consensus.
　　At the same time, because drinking less water, after a lot of exercise may also cause muscle dissolution! A 25-year-old young man suffered from swelling of muscles all over his body due to frantic exercise in hot weather, and his urine turned soy sauce. He was sent to the emergency department of Gongli Hospital in Pudong New Area by a friend and was diagnosed with rhabdomyolysis syndrome. Guo Dongfeng, the director of the emergency department, said that young people "too much iron" and fail to replenish the lost water in time have increased the risk of rhabdomyolysis syndrome. Guo Dongfeng said that although the cause of the disease is very complicated, in recent years, it has been heard about the disease caused by excessive exercise. He suggested that you should not exercise too much, do what you can, and replenish the water lost in the body in time after exercise, which is conducive to the elimination of metabolites and reduces the chance of kidney damage. If you find that your urine is soy sauce-colored, you must go to the hospital in time. (Reporter Zuo Yan)
