"Lao He, prepare for extracorporeal circulation." Zheng Ren touched down again, feeling the same as in the system operating room, and felt much more stable.
Lao He responded, turned on the timer on his phone, put it at hand, and hurriedly prepared the extracorporeal circulation accessories.
"Boss Zheng, where is the filter?" Liu Zewei asked when he saw Lao He starting to prepare the sterile pipeline.
In fact, he was not curious. This was a perfect opportunity to praise him, and it would be a pity to miss it.
"About 5cm below the pulmonary valve, there may be a pulmonary valve tumor, which slows down the blood flow and causes thrombus." Zheng Rendao: "The Fuguier filter is good."
The professor smiled on the side.
Zheng Ren just explained casually. He had not forgotten that this was a live broadcast surgery.
First use hemostatic forceps to separate the gap between the aorta and pulmonary artery, and cuff the ascending aorta.
The band over the ascending aorta is pulled to the left to expose the medial aspect of the superior vena cava.
Then Zheng Ren stretched out his hand and said: "Right angle..."
Before he finished speaking, the right-angled pliers were clenched in the palm of his hand.
Because extracorporeal circulation is required, Zheng Ren is worried that Xie Yiren will not be able to keep up with the operating procedures.
But he didn't expect that Xiao Yiren was still skillful. He raised his head, bent his eyes at Xiao Yiren, and smiled.
What awaited him was a pair of smiling eyes.
Their eyes met, and Zheng Ren forgot that he was still live broadcasting.
The doctors who watched the live broadcast of the surgery exploded instantly!
Having surgery and spreading dog food is simply intolerable!
"Boss, the live broadcast is going on." Su Yun reminded.
"..." Zheng Ren lowered his head and looked at the surgery area again.
At this moment, countless doctors watching the live broadcast of the surgery witnessed it with their own eyes.
This is the dream of many surgeons, to have a gentle and pleasant instrument nurse, and the two of them have the same mind.
It didn’t matter that the surgery was not as good as the surgeon’s, but he still had a good instrument nurse, and she actually smiled at him!
This wave of dog food has been spread, and resentment from all over the world has skyrocketed.
Zheng Ren didn't know what the doctors watching the live broadcast were thinking. He used a right-angle forceps to bypass the posterior cuff along the inner side of the superior vena cava. Use the same method to wrap the inferior vena cava cuff with the inferior vena cuff clamp as a backup.
"Lao He, are you ready?" Zheng Ren asked.
"Okay, start anytime." Lao He said in a deep voice.
For this operation, he adjusted his condition to the best level and wanted to show himself in front of Boss Zheng.
Opportunities are rare and fleeting.
After receiving Lao He's reply, Zheng Ren did not look up.
Reaching out his hand, he claps the needle holder into his palm. At the same time, Lao He clicked the timer button.
At the distal end of the ascending aorta, make two concentric purse-string sutures using No. 7 suture.
The purse-string suturing technique is extremely delicate. The small needle only penetrates the adventitia of the blood vessel but not the blood vessel. The No. 7 suture is sutured around the adventitia of the aorta.
"Boss, I thought you wanted to use a microscope." Su Yundao said.
"No, the aorta is so thick. I'm worried that my vestibular nerve won't be able to bear it after using the microscope for a long time." Zheng Ren said.
This is Zheng Ren's weakness. Riding a roller coaster will make you dizzy. Microsurgery, with a slight movement, the field of vision in front of me is like a roller coaster, the field of vision changes rapidly.
Although there is no up and down feeling, Zheng Ren tries to avoid too much time for microsurgery.
Zhao Yunlong remained silent as he watched Zheng Ren leave a purse string on the adventitia of the aorta.
Have you ever done a similar operation, and when have you not been careful
Although the aorta is very thick, the gap between the adventitia and the aortic trunk is surprisingly small. If you're not careful, blood will spurt out.
Although it was not fatal, it was very troublesome to stop the bleeding and the operation time was extended indefinitely.
Looking at Boss Zheng's operation, it is easy to do it with ease. The difficulty just now is not a difficulty at all in his hands, it is just an ordinary operation.
Zhao Yunlong was originally worried about Zheng Ren's level of extracorporeal circulation surgery, but after just one glance, he got the general idea.
The level is a geometric level higher than his own.
Zheng Renliu's purse line has one opening on the left and one on the left.
He put the purse string into the hemostatic device to stop the bleeding and fix it during intubation.
Cut off the outer membrane of the central part of the purse.
"Heparin, 3mg/kg." Zheng Ren said.
"It has been prepared for a long time." Lao He said. He knew that Boss Zheng was worried about his skills, but such detailed instructions were obviously a bit contemptuous, Lao He muttered in his heart.
Zheng Ren smiled, then injected heparin into the right atrial appendage, then used a lancet blade to make an incision in the center of the purse that was slightly smaller than the caliber of the arterial cannula. While withdrawing the blade, he inserted the arterial cannula into the ascending aorta incision.
At the same time, Su Yun immediately tightened the two purse string hemostats and used thick silk thread to fix the arterial cannula and the hemostat together.
Finally, the arterial cannula is fixed on the edge of the incision or the petiole of the spreader, and the cannula is connected to the artificial heart-lung machine.
Similar to this step, Zheng Ren then sewed a purse string on the right atrial appendage and right atrium and put on a hemostatic device.
Then make an incision, insert the superior and inferior vena cava cannula, and tighten the hemostat.
Use a thick silk thread to surround the cannula and ligate the atrial appendage and atrial wall 2 to 3 mm below the incision, and use this ligature to fix the upper and lower chamber cannulas to prevent slippage. Connect the upper and lower chamber intubations to the artificial heart-lung machine.
Lao He watched the operations on the operating table while observing the time.
He has performed at least several hundred cases of extracorporeal circulation. Extracorporeal bypass masters can determine the surgeon's surgical level by following the process of establishing extracorporeal circulation.
3′12″…
It was an outrageous time.
What was the previous record? Although it has not been completed, Lao He is sure that Boss Zheng will definitely break the national record.
Of course, this record is not officially certified.
There is a group of extracorporeal circulation specialists in large tertiary hospitals in Imperial Capital and Shanghai. In the group, everyone records the time it took for the experts in their respective hospitals to establish extracorporeal circulation.
Comparison only hurts.
It’s not them who are hurt anyway. If any of the chief surgeons has a lot of things to do and thinks he is a high-level surgeon, he can directly use the data to criticize others.
Lao He felt proud, but he didn't smile. Instead, he glanced at the time on the timer and went to work.
I'm afraid that if someone else undergoes extracorporeal circulation in the future, they will have to drive in an honest and gentle manner and make small jokes. With this number here, who dares to play big cards
Are you still shameless? !
Boss Zheng’s hand speed is too fast and extremely stable.
If you are not careful, you will delay the operation process. However, Lao He was proud that it would have been him, but someone else would have started to delay the operation at this time.
I don’t know if Boss Zheng can realize his own value, Lao He thought to himself.
What twin sisters, can they wear lead suits into the operating room? Can they be so skilled in cooperating with extracorporeal circulation
impossible!
Zheng Ren didn't know what Lao He was thinking, he was performing the operation silently.
