Chapter 2972 Command from anesthesia

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

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

“Yes.” Zheng Ren said,”it’s better for me to take care of her. Don’t leave.” Although the critical condition of our 912 is very strong, it’s still a 3D printed lung, after all, so we can’t be sure what will happen. I’m worried with them around. “

Su Yun’s lips moved. She wanted to retort, but she held it back in the end.

The others had already entered the operating room to make preparations early in the morning. The entire Medical Group attached great importance to this operation. Even Gao Shaojie had suggested to help out and cancel the tips operation for the day.

This request was rejected by Zheng Ren, so Gao Shaojie and Zhou chunyong had to go for the surgery. The others went to the large operating room early in the morning and started to make preparations in the innermost hybrid operating room.

He had been preparing for this surgery for a week, but when it was time to go on the stage, Zheng Ren felt a sense of homesickness. After changing their clothes in silence, Zheng Ren and Su Yun walked into the operating theater.

Director Xu was standing at the door of the operating room. When he saw Zheng Ren come in, he said with a bitter smile,”boss Zheng, where did you find this circulating nurse?”

“Ah?” Zheng Ren thought that director Xu was going to ask if there was anything he could help with, but he did not expect him to ask such a question.

“She’s an in-service training nurse from overseas. ” Su Yun was quick-witted and answered directly.

“Not even I can enter.” Director Xu complained.

“Uh …” Zheng Ren was speechless.”I told her yesterday to minimize the number of people to avoid damaging the sterile environment. I’m sorry, director Xu. “

“Boss Zheng, you won’t have to bring your own circulating nurses in the future, will you?” Director Xu said half-jokingly.

“I don’t know,” Zheng Ren was also at a loss about this matter.

“Chief Lin said that he’s a foreign friend with a big background.” Director Xu asked in a low voice.

“Well, you can consider me a patient.”

As they spoke, the three of them arrived outside the operating room. Maris was preparing all kinds of things for the surgery. After a period of training and adapting in the past few days, she was as skilled as the nurse of 912.

Today, Maris was wearing a hazmat suit. After a period of treatment, the fat in her lower body had been removed, and she had regained the figure she was proud of. Or to be more precise, she had turned into the shape that Chris had ordered for her.

Zheng Ren’s cosmetic surgery was done quite well. At least, from the back, one would think that it was a supermodel working in the operating room. It was impossible to tell that his lower body was like a mountain of meat and his upper body was as dry as a skeleton.

“Maris, this is the leader of this place, director Xu.” Zheng Ren introduced Maris to her after he entered.

Maris turned around and asked,”leader? Big brother Yun, what’s that?”

Hearing her question, Su Yun frowned. The atmosphere was a little awkward, and Zheng Ren felt that he might not even be as good as the professor, who had a big mouth. At the very least, the professor was a doctor. He knew the rules of the operating theater and would never have any conflicts with the people in charge of the operating theater.

“He can come in?” Maris also felt the awkwardness in the atmosphere, so she asked.

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

“There is.” Director Xu’s voice was a little dry. This was operating theater 912, and he actually needed permission to enter. This was ridiculous! If it wasn’t for boss Zheng’s request, he would have definitely flown into a rage.

“I’ll have to trouble you. ” Zheng Ren said.

“Zheng, is there anyone else?” Maris asked very seriously and stubbornly,”it’s not good for sterilization if too many people enter. That’s what the books say.”

“Dr. Charles will be here in a while, that’s all.” Zheng Ren said helplessly.

Zheng Ren and little stone exchanged a few words before looking at old he.

Old he was already prepared. He nodded and prepared the anesthesia.

“Wait a moment, I’ll go wash my hands first.” Zheng Ren said,”I’ll be in charge of this surgery from the beginning.”

Old he didn’t say anything about boss Zheng’s strange request. More than 20 pages of A4 paper weren’t enough, and boss Zheng had to command from the beginning. He seemed to be a little too careful.

Sometimes, old he even felt that boss Zheng treated this little patient in front of him differently from others.

Zheng Ren strode out to wash his hands and came back to put on his clothes. Lucky’s singing had already started. It was not loud and was more of a background.

Professor Charles stepped into the operating room. Lin Ge accompanied the doctor and explained to him the operation room of Room 912.

Zheng Ren narrowed his eyes and smiled, but he didn’t talk much with the doctor.

“Puncture the radial artery and do a blood analysis. Leave a sample first.” Zheng Ren put on his clothes and said as he stood in the corner.

Old he and his assistant started the operation quickly. Su Yun, Lin Yuan, and Gu Xiaoran had already started to lay out the sterile sheet and were ready to insert the ECMO tube.

“Mizodiazepine 1mg, etomidate 0.15 mg/kg. Shutendon 0.15mg/kg, traqumou vespenic acid 0.12mg/kg. ” Zheng Ren said in a deep voice.

The dosage of these drugs was determined after discussing with old he for a few days and Zheng Ren had tried it hundreds of times in the operating theater of the system. He had long memorized it by heart. However, this was the first time that Zheng Ren had cautiously taken over the command of a surgery. He did not even give up on the anesthesia.

Old he began to administer the medicine. After muscle relaxation, he placed an tracheal tube into the trachea and connected it to a ventilator for mechanical ventilation. For the tracheal ducts, he chose the left dual-chamber bronchi duct.

Zheng Ren also gave instructions on the values of the various ventilators. Then, he injected 0.02nag/kg/min of anesthetics, 1ug/kg/min of vecurodine, and interrupted intravenous injection of schutenfen.

The anesthesia took effect, and Su Yun brought Lin Yuan to get an ECMO.

Tubes were inserted into the right femoral vein, and a 15 QR catheter was used for the femoral vein, which was inserted to the level of the common ilial artery. The femoral vein was administered with a 19 QR catheter, and the tube was inserted to the inferior vena cava. A full-heparin coated membrane lung, tube, a temperature changer, a centrifugal pump head, and an oager were selected.

After the catheter was inserted, the cardiopulmonary bypass began. The initial flow was 2.5 L·min ” 1·m” 2 of the interrupted cardiac output, and it was maintained at more than 30% during the cardiopulmonary bypass.

Seeing that Little Rock’s vital signs were stable and his blood oxygen saturation level was rising, Zheng Ren began to place a sterile sheet and prepare for surgery.

The operating theater was quiet, and only the song of good luck was heard.

After the preoperative preparation was done, Zheng Ren stood at the surgeon’s position and focused on recalling the surgical process that he had already mastered. He reached out his hand after preparing the electroburner and the suction device.

The iodophor gauze from the hemostatic forceps was slapped into Zheng Ren’s hand.

He disinfected, made an incision, and took an anterolateral incision on both sides of the chest + sternum cross-section. The incision went between the fourth and fifth ribs on both sides, from the mid-succubus line to the edge of the sternum, and then the sternum.

This kind of incision could provide sufficient exposure to both sides of the chest from the top of the pleura to the diaphragm and the posterior medicinum, making it easier for the separation of the two lungs and the structures of the lunges. Although in recent years, there were people who suggested not to cross the sternum, Zheng Ren still chose the most “ancient” surgical method after surgical experiments.

Although the damage caused by this method was slightly greater, the surgery process was obviously shortened, so it was more suitable for small stones.

“Boss, are you nervous?” Su Yun asked with a chuckle as she stood in front of Zheng Ren and felt the heavy atmosphere in the operating theater.

“It’s alright. ” Zheng Ren’s eyes narrowed as he replied with a smile.
