2119 diaphragmatic lift compression cardiac resuscitation

With the vascular anastomosis magnetic ring, after Zheng Ren adapted, he quickly shortened the anhepatic period to an unbelievable extent

The previous 'world record' was like a sheet of paper, easily broken. And the experimental subject's cardiac arrest, an apparently insurmountable obstacle, was also smoothly overcome by Zheng Ren

Dozens of Surgical Training, the shortest time for anhepatic period surgery, 8 minutes 12 seconds

This is undoubtedly a huge breakthrough, but it is only a beginning

Zheng Ren focused on the surgery, installed the vascular anastomosis magnetic ring, during the opening of portal blood flow. This is the step Zheng Ren imagined as the most difficult

When cardiac blood supply suddenly resumed, whether the patient's heart failure-ridden heart could hold up became a problem

Indeed, within 3 seconds of restoring portal blood supply, the experimental subject's cardiac arrest occurred

After nearly 30 hours of Surgical Training, Zheng Ren drew a Conclusion: the surgery must be completed as quickly as possible under cardiac compression

However, cardiac compression's violent shaking affects the surgery. Moreover, open-chest direct-view cardiac compression causes too much trauma; even if Zheng Ren barely completes the surgery, its completion degree is not high

This means the patient will hardly survive the perioperative period

Zheng Ren didn't dare to step out of the door of the System Operating Room, as Su Yun that guy could be watching him from outside

Opening portal blood flow indeed causes sudden blood pressure changes, which Zheng Ren cannot solve

One cannot be like a magician, using a 'replacement' Skill to move the liver's position, can one

Vascular anastomosis magnetic ring can solve the problem of the anhepatic phase taking too long, and it also helps the patient before us to some extent, but it cannot solve all problems.

Zheng Ren tried ten Shou Bing, and finally, with no other recourse, he left the System Operating Room.

It seems there were still a few pay-to-win treasure chests that hadn't been opened.

Zheng Ren, who never liked leaving things to chance, would just set the box aside once he got it.

Actually, most of these boxes also contained experience points.

He glanced at the General Surgery Department's Skill Tree; the peak was still far off, a long way.

Even if a few boxes yielded massive amounts of Experience Points, it still couldn't let his General Surgery Department skill reach peak level, with a qualitative change.

Zheng Ren left the System Space.

This Shou Bing was truly a dilemma; after going back and forth, Zheng Ren also didn't obtain a satisfactory Solution.

"Boss, you think 15 Minute of anhepatic phase is impossible? Do you want to go to heaven?" Su Yun said contemptuously: "One Shou Bing, standard time is 3-4 Hour; I believe you can finish within 2 Hour. But the anhepatic phase time, previously at least 30 Minute, are you really preparing to shorten it to within 10 Minute?"

"The key isn't here." Zheng Ren's voice was a little hoarse, he said in a raspy voice: "Have you looked at the patient's recent cardiac ultrasound?"

"I have, and the condition is very bad."

"Well, I'm considering that after opening the portal venous flow, the pressure change will cause cardiac arrest." Zheng Ren entered a desperate state, not thinking about any flaws or loopholes, focusing all his attention on how to let the patient finish the Shou Bing safely.

"Should we stop the beat... or open the chest?" Su Yun pondered for a few seconds and then asked.

"Direct-view cardiopulmonary resuscitation is the last step. Liver transplantation has many postoperative problems; if we can avoid opening the chest and cause less trauma, that's best." Zheng Ren said firmly: "Vascular anastomosis magnetic ring, does the Hospital have one?"

"I'll get in touch." Su Yun said, "Cardiac arrest... thoracic... no, we've opened the abdominal cavity."

Zheng Ren stared for a moment, then immediately said, "Subdiaphragmatic!"

The method of performing cardiopulmonary resuscitation by lifting and squeezing the heart below the diaphragm is rarely seen clinically; it is an unconventional measure used in special circumstances.

After all, lacking sufficient experience, Zheng Ren, under Su Yun's reminder, was painstakingly piecing together the possibility of success.

Damn!

Zheng Ren finally found a complete path this time; all that's left is to put it into practice.

He immediately went to the System Space, purchased System Operating Room time, and entered the Operating Room.

This time, he practiced the subdiaphragmatic cardiopulmonary resuscitation technique. It was very difficult, especially under the premise of not affecting the Shou Bing. But Zheng Ren managed it, and the final successful compression method was what he learned from Fan Tian Shui.

Once, when going out to eat, they encountered a patient with spontaneous pneumothorax; Fan Tian Shui poked a straw into the waiter's chest cavity. That way of applying force concentrates power at a point and then releases it.

Zheng Ren remembered that after that, Su Yun had consulted Fan Tian Shui, and he also tried doing it a few times, imitating the manner.

If that guy could really learn it at a glance, there should be no problem; Zheng Ren could only pin his hopes on Su Yun. If that really doesn't work, then only Gai De·Wu Zi could do Shou Bing, while Zheng Ren himself would do the cardiac compressions.

Lin Yuan stared dumbfounded, wondering what was going on.

Having performed liver transplants at Harvard, with a procedure lasting about 3 Hour, it belongs to the advanced level of the global surgical community.

Moreover, the anhepatic phase varies in length depending on the surgeon's skill, but it still requires at least 30-40 Minute.

And Su Yun, with a single sentence, shortened the anhepatic phase to 15 Minute.

This still isn't the most critical point; Zheng Lao Ban seems dissatisfied with this time!

Moreover, he anticipated that when the portal venous flow was opened, cardiac arrest would occur……

Liver transplantation, with cardiac arrest occurring upon opening the portal venous flow, is not a rare complication; although Lin Yuan has never seen it firsthand, it always exists.

Is Zheng Lao Ban's this a case of foresight or having reached a certain level of skill, instantly killing himself…… himself not counting, directly instantly killing the Harvard Medical School mentors and professors.

Next step, is it to find a dummy and then try the technique? Lin Yuan is a bit confused. At first she could barely say a sentence or two, but now her thoughts can't keep up at all.

"The patient's condition requires a compression frequency of at least 100-120 per Minute." Su Yun said, "The key is when to stop."

Zheng Ren said, "Once the arterial blood vessels begin anastomosis, the patient's condition should improve somewhat."

"To restore normal physiological anatomical structure, under drug effect it's estimated to still need 1-2 Minute." Su Yun pondered.

Zheng Ren looked up, and it was only Su Yun.

"What are you looking at me for?"

"Do you still remember how you learned to exert force with Old Fan?" Zheng Ren asked.

"Of course." Su Yun looked dubiously at Zheng Ren, "Such a special compression? Come on! Boss, I can barely manage it, I can't last long!"

Zheng Ren felt greatly relieved hearing Su Yun say that.

"Zheng Lao Ban, I can do it!" Lin Yuan said.

"Don't talk nonsense, what can you do with those little arms and legs?" Su Yun retorted habitually.

"What can't be done with subdiaphragmatic cardiopulmonary resuscitation!" Lin Yuan snapped.

Tell me, how do you do it?

The right hand extends from the Shou Bing incision below the diaphragm, placing the 2-5 fingers together on the diaphragmatic surface posterior-inferior to the heart, while the left palm is fixed on the lower middle third of the sternum. Using coordinated movement of the right elbow, wrist, and shoulder joints, the right hand's 2-5 palm fingers rhythmically and impactfully lift and press toward the sternum, lifting the diaphragm 4-5 cm, then quickly relax to let the diaphragm return to its original position. Lin Yuan said skillfully.

"Tsk tsk." Su Yun wore a look of contempt.

"How?" Lin Yuan raised their head, flicking their ponytail.

"The basic theory is solid." Su Yun said, "It's not crucial; if necessary, I can do open-chest direct-view compression. The problem is the frequency of 100-120 compressions per Minute—how long can you hold up?"

"……" Lin Yuan was speechless.

This is manual labor, like carrying a thigh in an Orthopedics Department surgery.

It sounds not too difficult; ordinary people have also experienced external cardiac compression, and a few Minutes of high-frequency compression can still be maintained.

But whether the movement is correct is not certain.

But that is regular external cardiac compression, not subdiaphragmatic lift-and-squeeze cardiac resuscitation. This unconventional compression requires the right and left hands to coordinate, the posture is strange, and it is difficult to exert force.

But, these are not the most crucial.

Because the patient's condition is critical, we must shorten the procedure and restore normal anatomical structure.

Cardiac compression must be performed simultaneously with anastomosis of Blood Vessel.

The right hand is below the diaphragm, and the operator must also anastomose Blood Vessel, requiring great strength while not letting the patient's whole body move.

The difficulty thereof can be imagined.

With Su Yun present, Zheng Ren feels this surgery can be secured. Upon careful thought, it seems there is no significant deviation.

"I will do it as soon as possible." Zheng Ren said solemnly.

"It's fine." Su Yun laughed, "The thoracotomy equipment definitely needs to be prepared; I'll call Zhao Yunlong to come together. Once I... your surgery time will be relatively long, maybe you'll need to open the chest."

"Hmm." Zheng Ren nodded.

Preparedness prevents trouble; this is something that must be considered.
