Chapter 1020 D+3 day (4)

According to the schedule, Sun Lien should lead the team to the morning shift today.But because he had to attend a meeting at noon, he temporarily transferred a class with Director Lu Zhimin. Director Lu, who worked a whole day shift on the 26th, will take the doctors from the Comprehensive Diagnostic Center of the Fourth Central Hospital to stick to another day shift today.

And Sun Lien will cooperate with Lu Zhimin's team, Director Jiang Qingmin from the Endocrinology Department of the First Central Hospital, Director Tang Guozhi from the Department of Gastroenterology, Director Long Changsheng from the Neurology Department of the Second Central Hospital, and the Department of Hematology from the Affiliated Hospital of Ningyuan Medical College Director Meng Hongxiang worked the whole night shift together.

Four deputy directors, three attending doctors, and one Sun Lien.With eight doctors and 27 nurses to take care of 48 patients, manpower is still in short supply as usual.But Sun Lien felt a lot more relaxed.

On the fourth day when he came to Yunhe, he finally got two potentially effective weapons—tocilizumab, which had just been approved for small-scale clinical trials to observe the effect, was the same, while the other weapon was more valuable.

Professor Zhang Zhifu called Sun Lien at two o'clock in the afternoon to inform him of the arrival of this special weapon.

"The blood center has sent 800ml of convalescent plasma." On the phone, Professor Zhang Zhifu's excitement was beyond words. "I left 200 plasma for you in North Five District, AB type RH positive."

Convalescent plasma therapy is a recommended therapy for severe and critically ill patients in the guidelines.This experience has been verified during the SARS period, and it is also in line with the results of most researchers' research on human immunity and infection mechanisms.

For patients with pneumonia infected by the new coronavirus, it is not clear whether plasma therapy is effective.But its known and potential benefits far outweigh the potential and known risks.Coupled with the type AB plasma specifically mentioned by Professor Zhang Zhifu, this gave Sun Lien a lot of confidence.

Plasma transfusion also needs to check the blood type, but unlike red blood cells, type AB plasma is the most ideal one in terms of immunity.

Theoretically, the "combined blood" prepared by O-type washed red blood cells and AB-type plasma is the ideal blood transfusion after RH-negative O-type whole blood.After confirming that the patient's RH type is compatible, type O washed red blood cells without A and B agglutinogens and type AB plasma without A and B agglutinins can avoid all acute hemolytic transfusion reactions.

In other words, the 200ml of AB type RH positive convalescent plasma can be transfused to all non-RH negative blood patients.The neutralizing antibodies contained in these plasma can help patients develop passive immunity and quickly reduce the number of viruses in the body.

This is currently the most ideal antiviral treatment that doctors can find.

"Great." Sun Li'en almost jumped up happily, and then the energy of digging deep into the wall came out again, "But...Mr. Zhang, there are 48 patients in our ward. 200ml of serum Not enough."

"You don't need this set!" Zhang Zhifu suddenly became unhappy, "If you don't think it's enough of the plasma I specially reserved for you, then don't use it at all - other departments are also in short supply!"

Quanyunhe City currently has less than 80 cured and discharged patients, most of whom are middle-aged and elderly people or patients with underlying diseases.For plasma collection, the donor must be in good health, be at least 18 years old, and in principle not exceed 55 years old, and the body weight of men should not be less than 50 kg, and the body weight of women should not be less than 45 kg.

The three screening criteria of age, weight, and "physical health" basically screened out the recovered patients.And the voluntary principle screened the remaining people down to single digits.

Many people who have just escaped from the hands of death will have psychological stress on disinfectant and white coats.They can't wait to stay away from the hospital forever, as far away from needles and doctors as possible.This is a normal human reaction, very natural, and no wonder.

Rather, under such circumstances, there are still two recovered patients who decided to donate plasma, which is simply good news that came out of nowhere.According to the previous SARS experience, the plasma donated by a recovered person can be used by at least two to three people.

Sun Lien's plasma from convalescents could at least bring back a critically ill patient—how could he be unhappy?
"I'll go into the cabin now and arrange for them to analyze the patient's condition." Sun Li'en, who had the good news, felt that he had a lot of energy to work, "Mr. Zhang, 200 convalescent plasma is really not enough, please take care , think of ways to mobilize those recovered patients."

"There are only a few of the recovered patients who are of the right age. Where can I change a few more for you?" Zhang Zhifu was amused by Sun Lien's rascal appearance, "There are a few old party members among the recovered patients. Call me late and say you want to donate blood. But among these people, either the old lady is in her 44s and weighs [-] kilograms, or the old man has cancer. I dare to collect the plasma of these recovered people, do you dare to use it?"

"Anyway, don't worry about it." Sun Li'en would not be so stupid as to confront Zhang Zhifu. A qualified student of Liu Tangchun not only has to learn cunning from the fox, but also learns the ability to be slippery from the loach. "I'll be there soon, hang up first."

After wearing the industrial protective clothing, the cuffs, trouser legs and all zippers were tied with tape.Sun Li'en put on the goggles and took a deep breath, and pushed open the door to the red zone.

Li Chengping and other comrades on the small night shift were gathering to prepare for the morning handover meeting. After seeing Sun Lien and others coming in, Professor Li Chengping was stunned for a moment, making sure that the words "Sun Lien" were written on his chest, and then lowered his voice. Sun Lien asked, "Why did you come in wearing this kind of protective clothing?"

"There aren't enough medical ones, so I'll try wearing industrial ones first." Sun Lien was a little out of breath when he answered. Although this kind of industrial protective clothing is similar to ordinary medical protective clothing, it still takes a little effort to stick the tape.And now Sun Lien also regrets that he didn't put all the tapes on first, and then put on the mask.

Wearing a two-layer mask and bending over to stick tape everywhere, this action consumes much more oxygen than he expected.

"Are you... are you okay?" Seeing Sun Lien panting in the industrial protective clothing, Professor Li Chengping was nervous for a moment before thinking about it. It is estimated that Sun Lien is also a little confused about the effect of the industrial protective clothing. I was just a little bit nervous.At least not far from tachypnea.

Wearing a two-layer mask, the impact of tachypnea on the human body is much smaller than usual-the mask actually increases the length of the anatomical dead space of the human body, and tachypnea does not easily cause a drop in carbon dioxide concentration in the body.

"It's all right." Sun Li'en quickly raised his body. It is a very important principle to ensure that you are healthy and normal in the red zone - if your colleagues feel that you have a physical problem, they will be dragged out of the red zone and reimbursed for a set of protective equipment If it is serious, the protection should be released on the spot and the first rescue should be started. As a result, there is a high probability of infection with the new coronavirus.Therefore, there is a clear rule in the medical team: Once you feel unwell, you should immediately leave the red zone, enter the yellow zone and seek help from colleagues on duty.

Reimbursement for a set of protective clothing, this loss is still acceptable.But it would be an intolerable loss for a medical staff who came to Yunhe to be infected with the new coronavirus.

Secretary Chen has repeatedly told him to take all the treasures of Song An Province back.

"I'm fine, but I was a little suffocated at first." After Sun Lien explained the reason for his breathlessness, he conveyed the good news of Professor Zhang Zhifu to Li Chengping, "We have 200ml of convalescent plasma for use."

"Why didn't you get more?" Professor Li Chengping, who was born in Ningyuan Medical College, had a problem with Sun Lien, "Who is 200 enough for?"

"Now there are only two eligible rehabilitators, and a total of 800 have been brought back." Sun Li'en explained, "Professor Li, you are too dark, you have finally cured so few people, and you plan to drain them all? "
