Academician Zhong Nanshan's live video for the first time shared China's "new crown full path" experience; controlling social distance and wearing masks are more successful prevention and control experiences
China's epidemic is still under control and masks cannot be completely abandoned
Zhong Nanshan said that one of the most successful experiences of China's national defense control is the upstream prevention strategy. "This is one of the most successful experiences in China, which can further reduce the number of infections." In addition, controlling social distance and wearing masks are also more successful empirical methods for prevention and control in China. "
Beijing News Yesterday, Academician Zhong Nanshan, together with Dean He Jianxing and Associate Dean Li Shiyue of Guangzhou Respiratory Health Research Institute, broadcast live video for the first time to share China ’s screening of asymptomatic patients, diagnosis of suspected cases, treatment of diagnosed patients and severe ICU The "New Crown Full Path" experience of the later detection and online answer to the focus of the frontline doctors of anti-epidemic problems.
Talk about the onset
Fatigue and cough are more likely to become the first symptom of asymptomatic patients
Zhong Nanshan said that China is currently paying more attention to people with asymptomatic infections. According to the data, the incubation period of asymptomatic patients is mostly 3-7 days, and the highest incubation period may be 14 days. During the incubation period, many patients may not have symptoms, or the symptoms are very mild, and patients Is unclear.
Zhong Nanshan said that from the data, about 50% of asymptomatic patients have no symptoms of fever. Therefore, fever is not the core symptom of asymptomatic patients, and fatigue and cough are more likely to become the primary symptoms of asymptomatic patients.
Speaking of China's anti-epidemic experience, Zhong Nanshan said that one of China's most successful experiences in national epidemic control is upstream prevention strategies. Zhong Nanshan said that once the patient is infected with the new coronavirus, relevant departments will pay close attention to their close contacts. When someone is diagnosed, they need to be isolated at home, and their close contacts will also be isolated. "I think this is one of the most successful experiences in our country, which can further reduce the number of infections."
"On the other hand, controlling social distance and wearing masks is also a relatively successful experience in prevention and control in China." Zhong Nanshan said that even though China's current epidemic prevention has achieved certain results and fewer newly diagnosed patients, most people continue to abide by these rules .
Talking about diagnosis
Many mild patients have no abnormalities in lung CT imaging
Zhong Nanshan said that CT diagnosis is indeed very necessary, which depends on the application of CT equipment. He introduced that a small number of patients had no abnormalities and no imaging findings on routine CT examinations, but they had a positive virus test.
"In this case, I hope that there will be more advanced CT diagnostic technology, so that patients can be identified at an early stage." Zhong Nanshan said that many patients did not have abnormal CT imaging of the lungs throughout the course of the disease, they entered In the recovery period, this is also the performance of very mild patients.
Zhong Nanshan pointed out that new coronary pneumonia generally causes lung damage to patients and whether other organs are damaged. He believes that this is related to the patient's own complications.
"These patients may already have a disease, and you can see that the ultrasound and electrocardiogram change very quickly, so I think that patients with many comorbidities will find other organs damaged." Zhong Nanshan said that during the autopsy process, he did not see Clear damage to other organs based on the virus.
Zhong Nanshan said that at present, he observed that the patients showed some problems of the renal tubules, and there may be some damage to the renal tubules and necrosis of the renal tubules. "Other research teams have also found that 25% to 30% of patients will We found a very obvious kidney damage, which is what we currently know. "In addition to the damage to the heart, brain, and kidneys, the damage to the central nervous system is not so obvious.
Talk about treatment
Lianhua Qingwen is suitable for mild and non-severe patients
Zhong Nanshan said that Lianhua Qingwen had an inhibitory effect on the virus. There were 284 patients in the clinical study. The recovery rate of the treatment group was higher than that of the control group, but there was no significant difference from severe to mild. Therefore, Lianhua Qingwen Capsule may be more suitable for mild and non-severe patients with new crowns.
For the treatment, Zhong Nanshan said that inhaling a mixed gas of hydrogen and oxygen can relieve patients' difficulty in breathing, especially in critically ill patients. The research data on the inhalation of hydrogen-oxygen mixed gas will be published by the team in the next few weeks.
Introducing plasma therapy, Zhong Nanshan said that new coronavirus antibodies can be detected in the blood of patients in the rehabilitation period, and patients are regularly used in the plasma of the rehabilitation period. The viral load decreases significantly over time and then turns negative.
Zhong Nanshan said that China promotes the use of IGG and IGM for testing. “We not only use PCR testing (nucleic acid testing), but also add plasma antibody testing, especially for those patients whose PCR is recovering during the recovery period.” Zhong Nanshan said, These patients actually have antibodies to this virus in their bodies. Adding plasma antibody testing is a very good opportunity to allow us to better monitor the outbreak, which is worth promoting.
Talking about epidemic prevention
Prevention and control is very important during the resumption of production
Talking about whether China's epidemic prevention measures should be maintained, Zhong Nanshan said, "Everyone must maintain the understanding that China's epidemic situation is still in the control stage, and masks cannot be completely abandoned. The situation in China and abroad is different.
Zhong Nanshan said that he very much hopes that the epidemic in European countries will enter the platform period as soon as possible. During the platform period, the epidemic situation may show a restriction or a downward trend, so that more people can resume work and production, but prevention and control at this time are very important. "Imported cases are worth noting. There are imported cases on the Sino-Russian border and elsewhere, and they will continue to spread to other people. This is a big problem."
Zhong Nanshan said that some countries should not resume work urgently. The government may want to balance economic development and epidemic prevention. Health should be the first consideration.
In response to the United States, Zhong Nanshan said that although the number of global cases has tended to slow down or decline, the United States is an exception. The control measures adopted by the United States are not enough. It may take another week to see the changes in the epidemic before it can enter the platform stage of the epidemic, depending on what action the United States takes.
