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.
