It's almost the Chinese New Year, and the entire treatment team, including Sun Lien, and even Dr. Pascal and Brune are immersed in the joy of "coming to a holiday". Of course, Yuan Pingan did not have such good luck - according to the scheduling plan, from Chinese New Year's Eve to the sixth year of junior high school, he had to be on call in the fourth hospital throughout the whole process, always ready to receive patients, in general, emergency doctors have no human rights, and the resident chief physician of the emergency department does not even have the right to be treated humanely.

"It's a holiday next week, where are you going to have a vacation?" In the small conference room, a discussion about the holiday was in full swing. Zhou Ce and Xu Yourong are discussing whether to attend the high school reunion at the end of the year. Brunn, on the other hand, was looking at the map, as if he was planning to take his motorcycle farther north to satisfy a Texan's desire to see heavy snow - the snow in Ningyuan melted as soon as it fell, which seemed too unpleasant. Or head north to see the same snow as in Massachusetts.

"I'm going home. In response to Dr. Pascal's question, only Sun Lien answered seriously, "After all, when I went home before, I didn't even stay for a week, and I rushed back after meeting my parents twice." ”

Pascal laughed, "No matter what country it is, you should be with your family when you spend the holidays." He thought for a moment and said, "I plan to take the children to Shudi and take them to see pandas." ”

The short chat between parents naturally exudes a sense of intimacy and relaxation, which is also something that rarely appears in the chat content of ordinary doctors. Doctors may still have time to relax before surgery, but for emergency doctors, it's a real rarity.

"I've been nervous lately. On the other side, Zhou Ce, who was talking to Xu Yourong, suddenly mentioned a work-related topic, "You had an operation the day before yesterday, and two days later, the patient suddenly had pneumonia in the ICU. ”

"Pneumonia?" Xu Yourong frowned and thought about it, she hadn't heard the news, "Why did you make the hospital nervous again? Is it MRSA (methicillin-resistant Staphylococcus aureus) infection?"

Methicillin-resistant Staphylococcus aureus is the most severe type of hospital-acquired pneumonia. In addition to the rapid progression of the disease itself and the extremely serious consequences, the fact that "sensitivity to vancomycin alone" is enough to be anxious. The nosocomial epidemic of Staphylococcus aureus will also pose a great threat to other hospitalized patients. If you are not careful, someone may die. It's no wonder that the hospital department of the Fourth Courtyard is nervous.

"Not really. Zhou Ce shook his head, "C-reactive protein and D-dimer are both elevated, and there are lymphopenia, the total number of white blood cells is normal, and it feels like a viral infection." ”

Sun Lien pricked up his ears, he didn't feel much about the aforementioned MRSA—and it wasn't that he hadn't been treated. But viral infections are different. As the smallest microorganism, viruses themselves have a simple structure and a small body, which makes them much more troublesome to protect against than bacteria. What's worse is that there are no "broad-spectrum antiviral drugs" in the world. No single drug is effective against all viruses. Even ribavirin, the former first-line antiviral drug, only inhibits the reproduction of a variety of viruses in vitro. However, the effect is not optimal in the internal environment, and serious side effects may even occur.

If a viral infection is present, treatment is very limited. There is also the possibility of more severe nosocomial transmission. Because of its simple structure, the virus is also more viable than bacteria, fungi and parasites – the simpler the structure, the less susceptible it is to other factors – and if there is uncontrolled transmission of the virus in the hospital, the consequences can be unimaginable.

"Speaking of virus infection...... Xu Yourong suddenly looked at Sun Lien, "How is your nephew?"

Xiao Wang Tian was previously admitted to the NICU of the fourth hospital for treatment due to cytomegalovirus infection, and now his jaundice has been completely controlled. He was lucky that there were no serious sequelae. The child was discharged from the hospital two days ago.

"Discharged. Sun Lien sighed with some emotion, "I really dare not relax the work of the hospital, once there is a problem in this aspect, the price will be unacceptably heavy." ”

Xiao Wang Tian survived, but the other children in Changning Maternal and Child Health Hospital were not so lucky. Because of the problem of hospitalization, three newborn children lost their lives like this. The price is simply too high.

"So...... What did the courtyard sense say?" Sun Lien naturally intervened in the topic of Zhou Ce and Xu Yourong, "What problem do they suspect now?"

"The biggest suspicion at the moment is adenovirus. Zhou Ce replied, "The Department of Infection and Infection consulted and gave the patient ribavirin first. ”

Sun Lien nodded, adenovirus infected with pneumonia...... Adenovirus?his eyes widened, "Adenovirus circular?"

"That's right. "Zhou Ce hasn't reacted to what is wrong," this is what Yuan Sense suspects at the moment. ”

"In the ICU, there are cases of adenovirus infection?" Sun Lien frowned, the infection speed of adenovirus is very fast, from entering the body to the onset of the disease, it basically does not take more than a day. Moreover, in terms of the transmissibility of adenovirus, if the patient in the ICU who has just completed neurosurgery is infected with adenovirus in the ICU, then there will be multiple patients who will also be infected before and after his illness. "The hospital is so nervous...... But this is the only one patient who showed viral pneumonia?"

Zhou Ce nodded slowly, he also sensed that something seemed to be wrong here. "Something wasn't quite right, it seemed like ...... A little slow?"

"It's slow. Xu Yourong thought for a while and said, "I'll ask who the chief surgeon of this patient is." With that, she walked out the door and called.

Dr. Brunn scratched his itchy chin and asked Dr. Pascal, "What are they talking about?" He didn't understand the word adenovirus, but several ICUs did. But when a few people chatted, the speed of talking was too fast, and with his Chinese level of the three knives, he really didn't understand the specific content.

"They are suspicious...... The virus that is circulating in the hospital is not adenovirus. Dr. Pascal concluded, "Dr. Sun, do you think there's a problem here?" in the second half of the sentence, he asked Sun Lien.

"There's definitely a problem, but I don't know how serious it can be. Sun Lien replied, "You guys stay first, and I'll go to Shenwai to see the situation." Dr. Yuan, the patient pleases you. ”

Yuan Ping'an shrugged his shoulders helplessly, "You are the leader, you have the final say." ”

Sun Lien put on his N95 mask when he went out, and at the same time emphasized to his teammates, "Since there may be an epidemic of the virus in the hospital, then everyone must do a good job of personal protection." Don't forget the masks and gloves. ”

As soon as he walked out of the door of the small conference room, Sun Lien saw Xu Yourong with a somewhat solemn face, "The chief surgeon is Teacher Dong Xin, who is now in the Department of Respiratory Medicine." ”

"What is he doing in the Department of Respiratory Medicine?" Sun Lien didn't understand what Xu Yourong's words meant, "Director Huang, what patients need to be consulted with Shenwai?"

"He's not going to see a doctor, he's going to see a doctor. Xu Yourong shook his head, "Teacher Dong said that he had difficulty breathing, dry cough, and weakness, and was admitted to the inpatient ward of the Department of Respiratory Medicine this morning for examination and treatment. ”

"Let's go, let's see. Sun Lien walked to the inpatient department without hesitation, he always felt that something was wrong in his heart, a little awkward feeling that could not be explained. On the one hand, he doesn't believe that what could have caused so much tension in the four hospitals is just a sporadic case of adenovirus infection. On the other hand, he doesn't think adenovirus will develop so slowly.

It's not like an adenovirus...... Sun Lien frowned and quickened his pace. Dr. Dong Xin is a very responsible and humanistic doctor. He felt that he should do something for his colleagues.

As soon as he stepped into the eighth floor of the inpatient department where the respiratory medicine department was located, Sun Lien saw the familiar warning again. It was like a huge cordon, running through the entrance to the inpatient department.

"Warning, high risk of transmission", "Warning, fatal risk", "Warning, risk of pathogen mutation".

Sun Lien narrowed his eyes, and then silently put on his mask and goggles.

Avian influenza is a high risk of transmission, and pneumonic plague is a high risk of transmission and high fatality, so this carries the "risk of pathogen mutation...... And what is it?

"Sun, Sun, Sun...... Dr. Sun?" Director Huang Wenhui, who was not wearing a mask, happened to pass by the door, she looked at Sun Lien, who was fully armed, and was a little nervous and even stuttered for a while.

Sun Lien looked at Huang Wenhui and didn't speak, and the status bar on her head gave Sun Lien a chance to confirm his worries.

"Huang Wenhui, female, 39 years old, ,???? coronavirus infection. ”

Not adenovirus...... Sun Lien gasped, the four words of coronavirus, like a thunderbolt, made him stiff and unable to move. It was as if he had returned to that hot summer, the plague that affected the whole country, the coronavirus that took away his two uncles.

SARS。
