On January 16, the joint prevention and control mechanism of the State Council held a press conference on the health security of key groups. Mi Feng, spokesman of the National Health and Health Commission and deputy director of the Propaganda Department, pointed out that as the epidemic prevention and control entered a new stage, the country was carrying out classified dynamic services and "gateway forward" work for the elderly, children, pregnant women, patients with chronic basic diseases and other key groups in an orderly manner. Mi Feng stressed that it is necessary to detect and use drugs as early as possible for infection in key populations, and do a good job of regular contact services and daily health monitoring; Early identification and early referral of people at serious risk, and smooth referral channels; Intensive population should be concentrated in advance, strengthen the emergency force allocation, give priority to the treatment of high-risk patients, optimize the admission of inpatients, and ensure the inpatient needs and the treatment needs of critical patients. At the meeting, experts in the fields of the elderly, women and children, cardiovascular, nutrition, children and other fields gave answers to the common health problems of key groups one by one. After "Yangkang", do you still need to use drugs to consolidate it? "The symptomatic treatment of COVID-19 infection should be stopped in time after the symptoms disappear." Zhao Yangyu, director of obstetrics and gynecology at Peking University Third Hospital, said that while the drug has therapeutic effects, it also has some side effects. Zhao Yangyu suggested that to consolidate the treatment effect, pregnant women and other key groups should continue to pay attention to protection after "Yang Kang", and gradually restore the body to the pre-infection state through sleep, nutrition, exercise and other measures suitable for individuals. Zhao Yangyu said that if pregnant women infected with COVID-19 have no symptoms or very mild symptoms, they can not take drugs, and they can recover slowly by taking more rest, drinking moderate water and ensuring sleep; If the pregnant woman has symptoms such as fever above 38.5 degrees, and high fever will cause heat damage to the embryo, especially the embryo within 12 weeks, it is recommended to use drugs, and choose single preparation, and try not to use compound preparation. How fast is the heartbeat safe? "When you have a fever, your heart beats faster 10-12 times every 1 degree Celsius. When you have a fever above 39 degrees Celsius, it is normal for your heart beats faster." Zhou Yujie, executive vice president of Beijing Anzhen Hospital, said, but when your heart beats faster, you have to go to a doctor in time. Zhou Yujie said that there are some patients who do not have a fever, but have symptoms such as palpitation and tachycardia. At this time, they should go to the hospital to check myocardial enzymes, electrocardiogram, dynamic electrocardiogram, cardiac function, etc. If the results of these items are correct, it may be the result of sympathetic nerve excitation, which can be recovered slowly. Zhou Yujie suggested that if the heart rate of COVID-19 in the recovery period exceeded 100 times per minute and accompanied by panic, shortness of breath and chest distress, the myocardial enzyme and electrocardiogram should be checked in time. How to prevent and cure COVID-19 among people with chronic diseases? How should patients with chronic bronchitis, emphysema, cardiovascular and other basic diseases do well in disease treatment and COVID-19 prevention and treatment? Li Yanming, director of the Department of Respiratory and Critical Care Medicine of Beijing Hospital, said that both COVID-19 infection and chronic respiratory diseases belong to respiratory diseases. Once people with chronic respiratory diseases suffer from COVID-19 infection, they are prone to acute exacerbation of basic lung disease. Therefore, whether they have not yet been infected with COVID-19, are currently infected with COVID-19, or after "Yangkang", they should strengthen the diagnosis and treatment of chronic respiratory diseases and use drugs regularly. Li Yanming said that the respiratory system is slow
