Based on measurements of biomarkers of liver damage, the team found that the normothermic mechanical perfusion method caused 50% less damage to donor livers than the frozen storage method, increased the average liver shelf life by 54%, and reduced the organ discard rate by 50%.
Not only are there liver sources of the same blood type and matching type, but the donor livers are also sent thousands of miles away using a life support system at room temperature.
When he thought of this, Director Li couldn't help but feel a little dazed. Could it be that the world is unified
It is actually possible to do this—you must have a high status in academia. At the very least, doctors from the world's top hospitals must buy into it, otherwise who would be willing to do it
Seeing the liver taken out from the life support system, with the breath of life, the whole operating room was solemn.
When the Xie people received the donor liver, this side of the liver was cut off exactly, seamlessly, and there was no delay at all.
Director Li was dumbfounded. This was the most ideal situation for liver transplant surgery.
The cut donor liver has no blood supply, and if there is no blood supply for more than a minute, some changes will occur in the tissue.
Although everyone knows that seamless connection is the best way, there are no surgeons who can possibly achieve it.
Director Li stood on the operating table and acted as an assistant. With his rich experience, he felt many details that others could not feel.
Such details were filled in every corner of the operation, and Director Li was not even sure he understood them all.
For the chief director of the 912 Hepatobiliary Surgery Department who has extensive experience in liver transplantation, his hand speed may not be as fast as that of young people. But it would be too much if you can't even understand the operation.
The vascular anastomotic magnetic rings were installed one by one by Zheng Ren, and Director Li kept paying attention to the time. The shorter the liver-free period, the better. No one can deny this.
But is this the first time Boss Zheng has come across a magnetic ring for vascular anastomosis? Why are you so skilled!
"Lao He, dopamine has started to be pumped in at a trace level." Zheng Ren said while performing the operation.
"8ml per hour." Lao He said.
"Prepare to inject dopamine intravenously and prepare ten tubes of epinephrine." Zheng Ren said.
"..." Director Li looked at the ECG monitor in confusion. All the values on it were stable.
What is Boss Zheng doing
The electrocardiogram showed sinus rhythm, 124 beats/min. The rapid heart rate was considered to be caused by acute liver failure or infection and toxic shock. This was the result of the efforts of the top intensive care team at 912.
After a rescue operation, the patient's condition improved slightly, and at least in Director Li's opinion, there was no problem for the time being.
It is said that the older one is, the less courageous he becomes.
Boss Zheng is exactly the young white horse. He is so careful and cautious when wielding the sword. It is indeed interesting to watch.
It was time to transplant the liver. Director Li knew it in his heart and turned his gaze from the ECG monitoring to the operating area.
But,
The moment he looked away,
He felt as if he was hallucinating.
The ECG waveform fluctuates violently. Did you see it wrong? Director Li was stunned for a moment.
"Dopamine, adrenaline." Boss Zheng looked at the surgery area and said in a deep voice.
3 seconds ago, he had opened the portal vein.
Immediately after the portal blood flow was opened, patient Chen Li's vital signs began to change.
Uh... Director Li was stunned.
He immediately turned his head and looked around. The invasive arterial blood pressure monitor was like jumping off a building, with the values swooshing down.
It was still 90 mmHg just now, but the moment I turned my head and back, it dropped to 62 mmHg.
"Pa." Director Li's hand shook slightly, and Zheng Ren's hemostatic forceps hit Director Li's hemostatic forceps.
"Director Li, please concentrate, we don't have much time." Zheng Ren said in a deep voice.
Director Li was awe-inspiring.
It was obvious that Boss Zheng had his own plans and predictions for the entire operation.
There is not much time... He is not talking about ordinary terms such as the normal temperature period of organs, but the patient is really going to die!
Now that Boss Zheng was confident, Director Li stopped thinking about other things and began to concentrate on cooperating with Boss Zheng's surgery.
The moment the portal vein was opened, Su Yun no longer looked at the surgery field, but stared closely at the ECG monitor.
Blood pressure plummeted, arrhythmia, rapid atrial fibrillation.
There wasn't even time for the drug to be administered, and the blood pressure and heart rate immediately returned to zero.
After the venous blood supply to the heart was restored, the patient's heart, which had already suffered from heart failure, could not withstand such great pressure and stopped beating!
The electrocardiogram waveform went from frantically trembling to feebly moving twice, and was about to become a straight line.
The boss’s judgment is so accurate! Su Yun was slightly surprised.
But the boss’s judgment is accurate, isn’t that what it should be? Su Yun didn't know when he had a fixed mindset in his mind.
To say it has returned to zero is an exaggeration. Invasive arterial pressure monitoring shows a rapid decrease in arterial pressure, with the average arterial pressure being 20mmHg.
"The pupils on both sides are dilated, 4 mm in diameter, and the light reflex disappears." Lao He had been prepared. From the moment the ECG monitoring machine started to alarm, he began to observe the patient's pupils.
Su Yun stretched his right hand from the surgical incision below the diaphragm, placed 2-5 fingers together on the diaphragm attachment surface behind and below the heart, and placed the palm of his left hand on the previously reserved incision dressing. He knew that there was a patient underneath. The middle and lower 1/3 of the sternum.
Fix the palm of your left hand, use the coordinated movement of the right elbow, wrist and shoulder joints to drive the 2-5 metacarpal fingers of the right hand to rhythmically and impactfully push the sternum, so that the diaphragm moves up 5.5cm, and then quickly relax to return the diaphragm to its original position.
The entire movement standard is like a machine, without any error.
Although Su Yun's movements were very forceful and impactful, the patient's body remained steady and motionless.
Not to mention the entire body, even the nearby liver undergoing transplantation did not move at all.
Professor Zhang was dumbfounded on the side.
Cardiac arrest occurs suddenly, as if the patient's heart rate is transplanted into his heart.
The steady heart rate of 80 beats/min instantly reached over 150 beats/min. Finally, are you going to take the stage yourself
There was no excitement, just a hint of embarrassment.
Professor Zhang was a little dissatisfied with why Zhao Yunlong was so motionless. Shouldn't he be brushing his hands at this time, preparing to open his chest, and perform compressions under direct vision
He touched Zhao Yunlong with his arm.
"Xiao Zhao, brush your hands."
"Uh..." Zhao Yunlong watched Su Yun's movements without blinking, and just hummed a sound from his nasal cavity.
What kind of attitude is this? Professor Zhang hasn't noticed Su Yun's actions yet. He is very dissatisfied with Zhao Yunlong's reaction.
But Zhao Yunlong didn't move, and why didn't Director Zhang Lin move either!
1.2 seconds later, Professor Zhang noticed that the ECG oscilloscope, which had been stretched into a straight line, fluctuated again.
That kind of fluctuation means the continuation of life. But the waveform is not a sinus heart rate waveform, but a standard squeeze-and-raise waveform.
CPR? Professor Zhang was stunned.
I didn’t see anyone doing chest cardiac compressions, but who did the cardiopulmonary resuscitation!
