Chapter 2119 Heart resuscitation through the diaphragm
With the magnetic ring for vascular anastomosis, after Zheng Ren got used to it, he quickly shortened the time for the liver-less stage to an unbelievable degree.
The previous world record was like a piece of paper that could be broken easily. Zheng Ren had also successfully overcome the seemingly insurmountable obstacle of the experimental’s cardiac arrest.
Out of the dozens of surgeries he practiced, the shortest time he took to perform a non-liver stage surgery was 8 minutes and 12 seconds.
This was undoubtedly a huge breakthrough, but it was only the beginning.
Zheng Ren focused on the surgery. He installed the magnetic ring for vascular anastomosis and opened up the portal vein’s blood flow. This was the most difficult step in Zheng Ren’s mind.
It was a question whether the patient’s heart, which already had heart failure, would be able to withstand the sudden recovery of blood supply to the heart.
As expected, the experimental’s heart stopped beating three seconds after the blood supply to the portal vein was restored.
After nearly 30 hours of surgery training, Zheng Ren came to the conclusion that Wanwan had to complete the surgery as soon as possible while performing heart compressions.
However, the heart was pressed, and the violent trembling affected the surgery. However, the trauma caused by chest compressions under direct vision was too great. Even if Zheng Ren managed to complete the surgery, the completion rate was not high.
This meant that it would be very difficult for patients to survive the perioperative period.
Zheng Ren did not even dare to step out of the operating room. Su Yun was staring at him from outside.
Opening up the portal blood flow would indeed cause a sudden change in blood pressure, and Zheng Ren had no way to solve this.
He couldn’t possibly be like a mage who could use a skill like “replacement” to change the position of the liver, right?
The magnetic ring for vascular anastomosis could solve the problem of the patient not having liver for too long, and it would also be of some help to the patient before him. However, it could not solve all problems.
Zheng Ren tried ten operations and finally left the system operating theater helplessly when he was at the end of his rope.
It seemed that there were still a few in-game cash treasure chests that had not been opened.
Zheng Ren, who had never liked to try his luck, took the box and forgot about it.
In fact, most of these boxes were also filled with experience points.
He took a glance at the general surgery skill tree, and there was still a long way to go before he could reach the peak.
Even if he obtained a huge amount of experience points from a few boxes, it would not allow his general surgery technology to reach the peak level and have a qualitative change.
Zheng Ren left the system s.p.a.ce.
This was a very complicated surgery. After repeated trials and tribulations, Zheng Ren still did not get a satisfactory solution.
“Boss, you don’t think 15 minutes of the liver stage is enough? You want to go to heaven?” “The standard Time for a surgery is three to four hours, and I believe that you can finish it within two hours,” Su Yun said in disdain. But the time for the liver-free stage is at least thirty minutes before this. Are you really going to shorten it to ten minutes?”
“The key is not here.” Zheng Ren’s voice was a little hoa.r.s.e as he said in a hoa.r.s.e voice,””Have you seen the patient’s recent ultrasound?”
“I did. He’s not in a good state.”
“Well, I’m thinking that after the portal blood flow is opened, the change in pressure will lead to cardiac arrest.” Zheng Ren entered a state of desperation. He did not think about any flaws or loopholes. All his attention was focused on how to let the patient end the operation safely.
“Stop … Should I open up the chest?” Su Yun pondered for a few seconds before asking.
“Direct CPR is the last step. There are a lot of postoperative problems for liver transplantation. It’s best not to open the chest and cause greater trauma. ” Zheng Ren said firmly,”does the hospital have magnetic ring for vascular anastomosis?”
“I’ll make the contact. ” Su Yun said,”cardiac arrest … Thoracic Surgery … No, we’ve opened the abdominal cavity.”
Zheng Ren was stunned for a moment and immediately said,”F * ck!”
Travelling through the diaphragm to perform CPR was a rare clinical method, and it was an unconventional operation under special circ.u.mstances.
After all, he did not have enough experience. With Su Yun’s reminder, Zheng Ren tried his best to piece together the possibility of success.
F * ck!
Zheng Ren had finally found a complete path this time, and all that was left was to put it into practice.
He immediately went to the system s.p.a.ce, bought the system’s operation time, and entered the operating room.
This time, he was performing heart resuscitation through the diaphragm. It would be very difficult, especially when it did not affect the surgery. However, Zheng Ren still managed to do it. He had learned the final successful chest compression method from fan Tianshui.
When they had gone out to eat and encountered a patient with spontaneous pneumothorax, fan Tianshui had poked a straw into the waiter’s chest. The method of exerting force was to gather the power at a point and then burst it out.
Zheng Ren remembered that Su Yun had asked fan Tianshui for advice after that. He had also tried to do it a few times, and it looked decent.
If that fellow really knew how to do it with just one look, it should not be a problem. Zheng Ren could only place his hopes on Su Yun. If it really didn’t work, then only gade woods could perform the surgery and do the heart compression himself.
Lin Yuan was dumbfounded. What was going on?
He had performed a liver transplant at Harvard, and the surgery took about three hours. He was considered to be at the advanced level in the world of foreign surgery.
The length of the No liver period varied according to the skill of the surgeon, and it would take at least 30 to 40 minutes.
However, Su Yun shortened the liver-free period to 15 minutes with one sentence.
This was not the most important thing. Boss Zheng did not seem to be satisfied with the time!
He also predicted that there would be a cardiac arrest when the portal blood flow was opened …
Cardiac arrest after opening the hepatic portal vein for a liver transplant wasn’t a rare complication. Although Lin Yuan hadn’t seen it with his own eyes, it still existed.
Boss Zheng’s ability to predict the future was so high that he could beat him in seconds … He wasn’t a big deal, but he could beat all the teachers and professors at Harvard Medical School in seconds.
The next step was to find a fake person and then try out the hand technique? Lin Yuan was a little confused. At the beginning, she could still manage to say one or two sentences, but now, her thoughts could not keep up at all.
“Based on the patient’s condition, the frequency of chest compressions should be at least 100 times per minute.” Su Yun said,”the key is when it will end.”
Zheng Ren said,”after the artery is anastomosed, the patient’s condition should be better.”
“It will probably take one to two minutes for her to recover her normal physiological and anatomical structure under the influence of the medicine.” Su Yun was deep in thought.
Zheng Ren raised his head only to see Su Yun.
“Why are you looking at me?”
“Do you still remember how you learned how to use force from old fan?” Zheng Ren asked.
“Of course.” Su Yun looked at Zheng Ren in confusion.”Do you need such special chest compressions?” I’ll go! Boss, I can barely do it, but I can’t hold on for too long!”
Hearing Su Yun’s words, Zheng Ren was very pleased.
“Boss Zheng, I can do it!” Lin Yuan said.
“Don’t talk nonsense. What can you do with your small arms and legs?” Su Yun retorted out of habit.
“What’s wrong with CPR through the diaphragm?” Lin Yuan said angrily.
“Tell me how to do it.”
“Extend your right hand under the diaphragm from the surgical incision, place your two and five fingers together at the border of the diaphragm below the heart, and place your left palm at the lower 1/3 of the sternum to fix it. With the coordinated movement of the right elbow, wrist, and shoulder joint, drive the two to five fingers of the right hand to rhythmically push and squeeze toward the pectoral bone, so that the diaphragm moved up 4 to 5 cm, and then quickly relax the diaphragm to return to its original position. ” Lin Yuan said skillfully.
“Tsk, tsk.” Su Yun’s face was filled with disdain.
“What’s wrong?” Lin Yuan raised his head, his ponytail swinging.
“Your basic theory is very solid.” Su Yun said,”that’s not important. If it really doesn’t work, I can open up the chest and perform chest compressions under direct vision. The problem is, how long can you last at the frequency of 100 chest compressions per minute?”
Lin Yuan was speechless.
This was physical work, just like carrying someone’s thigh in an orthopedic surgery.
It did not sound difficult. An ordinary person had experience in chest compressions before, and they could still maintain a high frequency of chest compressions for a few minutes.
But whether the action was right or not was a different story.
However, that was a regular chest compression, not a heart resuscitation technique that was performed through the diaphragm. This kind of unconventional chest compression required the cooperation of the right hand and left hand. The posture was strange, and it was difficult to exert force.
However, this was not the most important thing.
Due to the patient’s critical condition, the surgery had to be shortened and the patient’s normal physiological and anatomical structure had to be restored.
Chest compressions had to be done at the same time as anastomosed blood vessels.
The right hand was below the diaphragm, and the surgeon had to anastomose the blood vessels. He needed to use a lot of strength, but he could not move the patient’s entire body.
One could imagine how difficult it would be.
With Su Yun around, Zheng Ren felt that he should be able to take down this surgery. Thinking about it carefully, there didn’t seem to be any deviation.
“I’ll do it as soon as possible,” Zheng Ren said solemnly.
“I’m fine. ” Su Yun smiled.”We definitely have to prepare a chest opening device. I’ll get Zhao Yunlong to come along.” If I … If your surgery takes too long, I might have to open up your chest. “
“Yes.” Zheng Ren nodded.
It was better to be safe than sorry, this was something that had to be considered.
