After entering the operating room, Lao He brought the little stone in, and Zheng Ren and Su Yun went to change their clothes.

"Boss, how many days and nights are you really going to visit ICU?" Su Yun asked.

"Yes." Zheng Ren said, "It's better for me to go to the care of my husband, so don't leave. Although our 912 has strong severe symptoms, it's 3D printed lungs after all, and it's not necessarily true that anything happens. I'm not at ease."

Su Yun's lips moved, and he wanted to make a few remarks, but he finally held them back.

Others went to the operating room early in the morning to prepare. The entire medical team attached great importance to this operation. Even Gao Shaojie asked to help and stopped today's tips operation.

This request was rejected by Zheng Ren, so Gao Shaojie had to go for surgery with Zhou Chunyong. The others arrived at the Dawai Operating Room early in the morning and started preparing with the innermost hybrid operating room.

This operation took one week to prepare, but when it was about to go on stage, Zheng Ren felt a sense of timidity. After changing his clothes silently, Zheng Ren and Su Yun walked into the operating room.

Director Xu stood at the door of the operating room. When he saw Zheng Ren coming in, he smiled bitterly and said, "Boss Zheng, where did you find the circuit nurse?"

"Ah?" Zheng Ren thought Director Xu was going to ask if there was anything he could do, but he didn't expect that he actually asked this question.

"A foreign advanced nurse." Su Yun answered cleverly.

"I don't even let me in." Director Xu complained.

"Uh..." Zheng Ren was speechless, "I told her yesterday, try to avoid destroying the sterile environment. Sorry, Director Xu."

"Boss Zheng, you won't be able to take the nurses on your own in the future." Director Xu said half-jokingly and half-takingly.

"I don't know." Zheng Ren was also confused about this matter.

"Chief Lin said that this is a foreign friend and is of great origin." Director Xu asked in a low voice.

"Well, I should be considered a patient."

While speaking, the three of them came outside the operating room. Maris was preparing various things for surgery. After a period of training and adaptation in recent days, she was as skilled as a nurse in 912.

Today, Maris is wearing an isolation suit. After a period of treatment, the fat in her lower body was removed and she regained her proud figure; or, more accurately, she became the one that Kerry helped her customize.

Zheng Ren did a very good cosmetic surgery. At least he thought that the supermodel from the back was busy in the operating room. He couldn't tell that his lower body was like a meat mountain, and his upper body was withered and like a devil like a skeleton.

"Marys, this is the leader here Director Xu." Zheng Ren introduced to Maris first after coming in.

Maris turned her head and asked, "Leader? Brother Yun, what is that?"

When Su Yun heard her question, she frowned. The atmosphere was a little awkward. Zheng Ren felt that it seemed that he was not as good as a professor who was full of thorns. At least the professor was a doctor. He understood the rules of the operating room and would never have conflicts with the people who managed the operating room.

"Can he come in?" Maris also felt the awkward atmosphere, and she asked.

"Come in..." Zheng Ren arrived, "Director Xu, do you have time to help with your help?"

"Yes." Director Xu's voice was a bit dry. This was the operating room of 912. He actually had to get permission to enter. It was really outrageous! If it weren't for Boss Zheng's request, he would definitely be angry.

"Please trouble you." Zheng Ren said.

"Zheng, are there anyone else?" Maris asked very seriously and stubbornly, "If you enter too much, it is not conducive to sterility. This is what the book says."

"Dr. Charles is coming soon, and the rest will be gone." Zheng Ren said helplessly.

Zheng Ren and Xiao Shitou said something, then looked at Lao He.

Old He was already ready, so he nodded and prepared for anesthesia.

"Wait a moment, I'll go and clean my hands first." Zheng Ren said, "I will start to direct this operation."

Lao He didn't say anything about Boss Zheng's strange request. More than 20 pages of A4 paper are not enough, and Boss Zheng has to start commanding again, so he seems to be a little too careful.

Sometimes Lao He thinks that Boss Zheng is different from others in front of him.

Zheng Ren strode out to brush his hands and came back to put on his clothes. The singing of Good Luck has already sounded, but it is not loud, but it is more of a background.

Dr. Charles began to come to the operating room while the operation was on the operation room. Linger was with the doctor and explained to him the operating room of 912.

Zheng Ren narrowed his eyes and smiled, but did not talk much with the doctor.

"Radial artery puncture, blood qi analysis, leave a sample first." Zheng Ren put on his clothes and stood in the corner and said.

Lao He and his assistants started to operate quickly. Su Yun, Lin Yuan, and Gu Xiaoran had already started laying sterile sheets and were preparing to do ECMO pipe storage.

"Imidazolam 1mg, etomidate 0.15 mg/kg. Sufentanil 0.15 mg/kg, atracuronium cisphenylsulfonate 0.12 mg/kg." Zheng Ren said in a deep voice.

The dosage of these drugs was the result of discussing with Lao He for a few days and Zheng Ren tried it hundreds of times in the system operating room. He was familiar with the chest. However, Zheng Ren was cautious and took the command of the surgery for the first time and did not even give up anesthesia.

Lao He started giving the medicine, and after relaxing the muscles, he performed endotracheal intubation, connected to a ventilator for mechanical ventilation, and selected the left double-cavity bronchial catheter for both tracheal catheters.

Zheng Ren also explained the values ​​of various ventilators, and then intravenously injected propofol 0.02 nag/kg/·min, vecuronium bromide 1ug/kg/·min, and intermittent intravenous injection of sufentanil.

After the anesthesia took effect, Su Yun took Lin Yuan to ECMO.

The right femoral artery vein is intubated, and the femoral artery is 15 Fr catheter is intubated to the level of the common iliac artery; the femoral vein is 19 Fr catheter is intubated to the level of the inferior vena cava. The entire heparin-coated membrane of the lungs and pipes, thermostats, centrifugal pump head and oxygenator are selected.

The flow transfer starts after the catheter is placed, and the initial flow rate is 2.5 L·min-1·m-2 of the interrupted center output, and it remains above 30% during the flow.

Seeing that Xiao Shitou's vital signs were stable and his blood oxygen saturation was rising, Zheng Ren began to lay a sterile sheet and prepare for the operation.

The operating room was quiet, only the song of good luck was floating.

Before the operation, Zheng Ren stood at the position of the surgeon and recalled the mature surgical process. After preparing for the electric scorching and attraction, he reached out.

The iodine gauze clipped with the hemostatic forceps was patted in Zheng Ren's hand.

Disinfect, incision, and take the anterior and lateral incision on both sides of the thoracic area-transverse sternum. The incision passes through the 4th or 5th intercostals on both sides, from the mid-axillary line to the sternum margin, and then crosses the sternum.

This incision can provide sufficient exposure to the thoracic cavity on both sides from the pleura to the diaphragm and the posterior mediastinum, making it easier to free the structure of the lungs and the hilar structure. Although some people have proposed not to cross-section of the sternum in recent years, Zheng Ren chose the most "oldest" procedure after surgical experiments.

Although the damage caused by this method is a little larger, the surgical process is significantly shortened, making it more suitable for small stones.

"Boss, are you nervous?" Su Yun stood opposite Zheng Ren, feeling the atmosphere in the operating room a bit solemn, and he asked with a smile.
