Chapter 2118 Cardiac Resuscitation Through Diaphragmatic Lift
With the vascular anastomosis magnetic ring, after Zheng Ren got used to it, he quickly shortened the time of the anhepatic period to an unbelievable degree.
The previous "world record" is like a piece of paper, which can be broken with a poke. The experimental subject's cardiac arrest and seemingly insurmountable obstacles were also successfully overcome by Zheng Ren.
Dozens of operations were trained, and the shortest time for anhepatic surgery was 8 minutes and 12 seconds.
This is undoubtedly a huge breakthrough, but it is only the beginning.
During Zheng Ren's intensive operation, the magnetic ring for vascular anastomosis was installed, and the blood flow in the portal vein was opened. This is the most difficult step in Zheng Ren's mind.
Sudden recovery of blood supply to the heart, whether the heart of the patient already has heart failure can sustain it is a question.
Sure enough, within 3 seconds of restoring the blood supply of the portal vein, the subject suffered cardiac arrest.
After nearly 30 hours of surgical training, Zheng Ren came to a conclusion—the operation must be completed as soon as possible under the condition of cardiac compression.
However, the heart was pressed and the severe tremor affected the operation. However, the chest was opened and the heart was pressed under direct vision. The trauma was too great. Even if Zheng Ren managed to complete the operation, the degree of completion of the operation was not high.
This means that it is difficult for patients to survive the perioperative period after surgery.
Zheng Ren didn't even dare to leave the door of the operating room of the system, but that bastard Su Yun was staring at him from outside.
Opening up the blood flow in the portal vein will indeed lead to a sudden change in blood pressure, which Zheng Ren has no way to solve.
It can't be like a magician, if a "replacement" skill is used, the liver will change its position, right?
The vascular anastomosis magnetic ring can solve the problem of too long anhepatic period, and it can also help the patient in front of him to some extent, but it can't solve all the problems.
Zheng Ren tried ten operations, but at the end of his life, he left the operating room of the system in desperation.
It seems that there are still a few krypton gold treasure chests that have not been opened before.
Zheng Ren, who has always had little love for luck, got the box and forgot it.
In fact, most of these boxes are also experience points.
He glanced at the skill tree of general surgery. It was still a long way from the peak.
Even if a few boxes have opened a large amount of experience points, it is still impossible to make my general surgery skills reach the peak level and make a qualitative change.
Zheng Ren left the system space.
This time it was a really tangled operation, and even after repeated tossing, Zheng Ren couldn't get a satisfactory solution.
"Boss, 15 minutes of anhepatic period doesn't work for you? Do you want to go to heaven?" Su Yun said contemptuously: "The standard time for a surgery is 3-4 hours, I believe you can finish it within 2 hours. But the time of the anhepatic period was at least 30 minutes before, are you really going to shorten it to 10 minutes?"
"That's not the point." Zheng Ren's voice was a little hoarse, and he said hoarsely, "Have you read the patient's latest echocardiogram?"
"Look, the condition is very bad."
"Well, I think that after opening the blood flow in the portal vein, the change in pressure will lead to cardiac arrest." Zheng Ren entered the state of jumping over the wall, not thinking about any loopholes or loopholes, and all his attention was devoted to how to make the patient safe. Finish the surgery.
"Stop jumping...do you want to open your chest?" Su Yun asked after pondering for a few seconds.
"Cardiopulmonary resuscitation under direct vision is the last step. After liver transplantation, there are many problems. It is best not to open the chest and cause greater trauma." Zheng Ren said firmly, "The vascular anastomosis magnetic ring, the hospital has Is it?"
"Let me get in touch." Su Yun said, "Cardiac arrest...external chest...no, we opened the abdominal cavity."
Zheng Ren was taken aback for a moment, and immediately said, "Your Majesty!"
The method of lifting and squeezing the cardiopulmonary resuscitation through the diaphragm is rarely seen in clinical practice, and it is an unconventional operation method under special circumstances.
After all, he didn't have enough experience. Under the reminder of Su Yun, Zheng Ren worked hard to piece together the possibility of success.
Dry!
Zheng Ren finally found a complete path this time, and the rest is practice.
He immediately came to the system space, bought system operation time, and entered the operating room.
This time, he practiced transdiaphragmatic CPR. It is very difficult, especially if it does not affect the operation. But Zheng Ren did it anyway, and the final successful way of pressing was learned from Fan Tianshui.
When going out to eat, Fan Tianshui poked a straw into the chest cavity of the waiter when he encountered a patient with spontaneous pneumothorax. The way of exerting force is to gather the strength at one point and then burst out.
Zheng Ren remembered that Su Yun asked Fan Tianshui for advice after that, and he also tried to do it a few times, looking decent.
If that guy really takes a look at it, it should be fine. Zheng Ren can only pin his hopes on Su Yun. If it doesn't work, then Gerd Woods can only do the surgery and do the heart compressions himself.
Lin Yuan was dumbfounded, what's going on?
He did a liver transplant at Harvard, and the operation lasted about 3 hours, which is at the advanced level in the world's surgical field.
The length of the anhepatic period varies according to the level of the surgeon, and it takes 30-40 minutes.
And Su Yun shortened the anhepatic period to 15 minutes with one sentence.
This is not the most important thing, Boss Zheng seems not satisfied with this time!
And it is expected that when the blood flow of the portal vein is opened, there will be a sudden cardiac arrest...
Cardiac arrest due to liver transplantation is not a rare complication. Although Lin Yuan has never seen it with his own eyes, it always exists.
Boss Zheng, is this a foresight, or has his level reached a certain level, and he directly kills himself... It doesn't matter to him, he directly kills all the tutors and professors of Harvard Medical School.
The next step is to find a dummy and try the tricks? Lin Yuan was a little confused. At first, she could barely speak a word or two, but now she can't keep up with her train of thought at all.
"For the patient's condition, the compression frequency should be at least 100-120 times per minute." Su Yundao, "The key is when is the size."
Zheng Rendao, "After the anastomosis of arteries begins, the patient's condition should be relieved."
"It will take 1-2 minutes to restore the normal physiological and anatomical structure under the action of drugs." Su Yun pondered.
When Zheng Ren looked up, it was only Su Yun.
"What do you see me doing?"
"Do you still remember how you and Lao Fan learned how to exert force?" Zheng Ren asked.
"Of course." Su Yun looked at Zheng Ren suspiciously, "Want such a special pressure? I'll go! Boss, I can barely do it, and it won't last too long!"
Zheng Ren was very pleased to hear what Su Yun said.
"Boss Zheng, I can do it!" Lin Yuan said.
"Don't talk nonsense, what can you do with those little arms and legs." Su Yun habitually ranted over.
"CPR through the diaphragm, what can't be done!" Lin Yuan said angrily.
"Tell me how to do it."
"Extend the right hand under the diaphragm from the surgical incision, place 2-5 fingers together on the attachment surface of the diaphragm under the back of the heart, and place the left palm on the lower middle 1/3 of the sternum for fixation. Use the right elbow, wrist and shoulder joint to coordinate the movement Drive the 2-5 palm fingers of the right hand to rhythmically lift and squeeze the sternum, so that the diaphragm moves up 4-5cm, and then quickly relax so that the diaphragm returns to its original position." Lin Yuan said skillfully.
"Tsk tsk." Su Yun looked contemptuous.
"What?" Lin Yuan raised his head and flicked his ponytail.
"The basic theory is very solid." Su Yundao, "It's not critical. It's really not possible. I can do chest compressions under direct vision. The problem is the frequency of 100-120 compressions per minute. How long can you last?"
"..." Lin Yuan was speechless.
This is physical work, like carrying a thigh in orthopedic surgery.
It sounds like nothing difficult. Ordinary people have had exposure to chest compressions, and high-frequency compressions can still be maintained for a few minutes.
But it doesn't matter whether the action is right or not.
But that was routine chest compressions, not subdiaphragmatic lift and squeeze CPR. In this unconventional pressing, the right and left hands must cooperate with each other, the posture is weird, and it is very difficult.
But, this is not the most important thing.
Because the patient's condition is critical, the operation must be shortened and the normal physiological and anatomical structure must be restored.
Cardiac compressions should be performed simultaneously with the anastomosis.
The right hand is under the diaphragm, and the operator also needs to anastomose the blood vessels, which requires great strength without allowing the patient's entire body to move.
One can imagine the difficulty.
With Su Yun here, Zheng Ren felt that this operation should be possible. If you think about it carefully, there seems to be no deviation.
"I will do it as soon as possible." Zheng Ren said solemnly.
"It's okay." Su Yun said with a smile, "the thoracotomy equipment must be prepared. I'll call Zhao Yunlong to come with me. Once I... your operation time is relatively long, maybe you have to have a thoracotomy."
"Yes." Zheng Ren nodded.
Be prepared, this is something that must be considered.
