Chapter 2971 Command From Anesthesia

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

"Boss, are you really going to visit the ICU for a few days and nights?" Su Yun asked.

"Yeah." Zheng Ren said, "It's better for me to go take care of it, and you don't want to go. Although our 912 is very powerful, it is a 3D-printed lung after all, so there is no certainty about what will happen to it. I don't worry about them. .”

Su Yun's lips moved, wanting to say something, but he held back in the end.

The others entered the operating room early in the morning to make preparations, and the entire medical team attached great importance to this operation. Even Gao Shaojie asked to come to help and stop today's tips operation.

This request was rejected by Zheng Ren, so Gao Shaojie had no choice but to go to the operation with Zhou Chunyong, and the others went to the big surgery room early in the morning, and started preparations in the innermost hybrid surgery room.

It took a week to prepare for this operation, but when it was time to go on stage, Zheng Ren felt a sense of homelessness. After changing their clothes in silence, Zheng Ren and Su Yun walked into the operating room.

Director Xu stood at the door of the operating room. Seeing Zheng Ren coming in, he said with a wry smile, "Boss Zheng, where did you find the itinerant nurse?"

"Ah?" Zheng Ren thought Director Xu was going to ask if there was anything he could do to help, but he didn't expect him to ask such a sentence.

"Nurses who are studying abroad." Su Yun replied cleverly and directly.

"Even I won't let in." Director Xu complained.

"Uh..." Zheng Ren was speechless, "I told her yesterday, try to keep as few people as possible, so as not to damage the sterile environment. I'm sorry, Director Xu."

"Boss Zheng, from now on you won't be able to take care of the itinerant nurses." Director Xu said half-jokingly and half-seriously.

"I don't know." Zheng Ren was also at a loss about this matter.

"Director Lin said that this is a foreign friend with a great background." Director Xu asked in a low voice.

"Well, I should be regarded as a patient."

While speaking, the three of them came to the operating room. Maris is preparing various things for surgery. After a period of training and adaptation in the past few days, she is as proficient as a 912 nurse.

Today, Maris is wearing an isolation suit. After a period of treatment, the lower body fat has been removed, and she has regained a proud figure; or more accurately, it has become the appearance that Kerry helped her order.

Zheng Ren's cosmetic plastic surgery is quite good. At least from the back view, he thought it was some supermodel busy in the operating room. He couldn't tell that the lower body was like a mountain of meat, and the upper body was haggard like a skeleton.

"Maris, this is Director Xu, the leader here." Zheng Ren introduced to Maris after entering.

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

Hearing her question, Su Yun frowned. The atmosphere was a bit awkward, and Zheng Ren felt that it was not as good as the professor who was full of scorn. At least the professor is a doctor, he understands the rules of the operating room, and will never conflict with the person in charge of the operating room.

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

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

"Yes." Director Xu's voice was a bit dry. This is the operating room of 912. It's really unreasonable that I have to get permission to enter! If it weren't for Boss Zheng's request, I would definitely lose my temper.

"I'm sorry to trouble you," Zheng Ren said.

"Zheng, is there anyone else?" Maris asked seriously and stubbornly, "Too many people enter is not conducive to sterility, that's what the book says."

"Dr. Charles will come in a while, and there will be nothing left." Zheng Ren said helplessly.

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

Lao He was already ready, he nodded and prepared to anesthetize.

"Wait a minute, I'll go brush my hands first." Zheng Ren said, "I'll direct this operation from the beginning."

Lao He didn't say anything about Boss Zheng's weird request. More than 20 pages of A4 paper were not enough, and Boss Zheng had to start from the beginning. It seemed a little too careful.

Sometimes Lao He feels that Boss Zheng treats the little patient in front of him differently from others.

Zheng Ren strode out to brush his hands, and when he came back to put on his clothes, the singing of good luck had already sounded, not loudly, more as a background.

Dr. Charles came to the operating room stepping on the beginning of the operation, and Linge accompanied the doctor, explaining the 912 operating room to him.

Zheng Ren narrowed his eyes and smiled, but didn't talk to the doctor much.

"Puncture the radial artery, do blood gas analysis, and take a sample first." Zheng Ren put on his clothes and said standing in the corner.

Lao He and his assistant quickly started the operation, and Su Yun, Lin Yuan, and Gu Xiaoran had already started laying sterile sheets, preparing for ECMO catheterization.

"Midazolam 1 mg, etomidate 0.15 mg/kg. Sufentanil 0.15 mg/kg, atracurium cis-besylate 0.12 mg/kg." Zheng Ren said in a deep voice.

The dosage of these medicines was the result of discussing with Lao He for a few days and Zheng Ren tried hundreds of times in the operating room of the system, and he was familiar with it by heart. But Zheng Ren took over the command of the operation cautiously for the first time, and he didn't even give up the anesthesia.

Lao He began to administer medication, and after muscle relaxation, endotracheal intubation was performed, and he was connected to a ventilator for mechanical ventilation. The left double-lumen bronchial tube was selected as the endotracheal tube.

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

The anesthesia took effect, Su Yun took Lin Yuan off ECMO.

The right femoral artery and vein were cannulated, and the femoral artery was cannulated to the level of the common iliac artery with a 15 Fr catheter; the femoral vein was cannulated to the level of the inferior vena cava with a 19 Fr catheter. Use whole heparin-coated membrane lungs and pipelines, thermostats, centrifugal pump heads and oxygenators.

After the catheter was placed, the flow was started. The initial flow was 2.5 L·min-1·m-2 of the intermittent cardiac output, and it was maintained at more than 30% during the flow.

Seeing that Xiaoshi's vital signs were stable and his blood oxygen saturation was rising, Zheng Ren began to lay down sterile drapes to prepare for the operation.

The operating room was quiet, only the singing of Good Luck was floating.

After making preoperative preparations, Zheng Ren stood on the operator's seat, concentrating on recalling the mature operation process, and stretched out his hand after preparing the electric cauterization and suction device.

The iodophor gauze held by the hemostatic forceps was slapped in Zheng Ren's hand.

Disinfect, cut open, and take both sides of the thoracic anterolateral incision + sternal transection. The incision is made through the 4th or 5th intercostal space on both sides, from the midaxillary line to the sternal border, and then crosses the sternum.

This incision can provide sufficient exposure of both sides of the chest from the top of the pleura to the diaphragm and the posterior mediastinum, making it easier to mobilize the two lungs and the hilar structures. Although some people have proposed in recent years that there is no need to transect the sternum, Zheng Ren still chose the "oldest" surgical method after undergoing surgical experiments.

Although the damage of this method is a little larger, the operation process is significantly shortened, and it is more suitable for small stones.

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

"It's okay." Zheng Ren narrowed his eyes and replied with a smile.
