Facing Zheng Ren's relaxed smile, everyone's nervousness was also relieved a little.

The operation began, after opening the chest, Zheng Ren cut the mediastinal pleura around the root of the lungs, and bluntly separated to the lung side, revealing the hilar blood vessels.

Then Lin Yuan and Gu Xiaoran stretched the upper and lower lobe lungs to the posteriorly, exposing the anterior edge of the lung. First, separate the superficial superior lung vein, ligate and cut off the upper and middle lobe veins respectively.

Dr. Charles stood silently and watched the operation, his pupils gradually shrank.

The standard total pulmonary resection procedure is a textbook-level surgery. After 15 minutes of opening, the arteriovenous artery and vein in the right lung have been exposed and ligation begins.

The doctor could see that Zheng Ren did not deliberately pursue speed, but performed a surgery step by step. It was just that the surgery was performed very smoothly. Not only the operator and Yisuke, but also Nisuke and Sansuke were quite familiar with the operation process and had a tacit understanding of the operation.

What do artists most hope for?

The most hope is that the art field is clean, not only that bleeding will block the sight, but also that other tissues can be pulled apart with a pull hook, exposing the art field is also very important.

When Zheng Ren was bluntly separated on the right lung side and exposed the hilar blood vessels, Ersuke Lin Yuan and Sansuke Gu Xiaoran pulled out all the tissues that should be pulled out in advance, and the surgical field was exposed quite fully.

During the surgical practice, Dr. Charles did not notice the role of the assistant. At that time, he focused all his attention on the 3D-printed lung tissue donor; on Zheng Ren's microsurgery skills.

Today, when facing a real patient and looking at the operation from the beginning, Dr. Charles believes that the performance of the two young people is perfect.

The surgery was not done by one person. Today, Nisuke and Sansuke perfectly interpreted this.

"Liver function, alanine aminotransferase..."

"Blood Qi Analysis..."

After 15 minutes, Lao He began to report the test results. Liver and kidney function, blood and gas analysis, and several main indicators were clearly reported.

"Next time." Zheng Ren answered simply. Others sounded stupid, but Lao He nodded and signaled that he understood.

The assistant next to Dr. Charles translated for him behind him, and the doctor began to think about these numerical issues.

Now, the total bilirubin of liver function is 89μmol/L, which is 4 times higher than the upper limit of the normal value. However, according to the records of the medical records, the total bilirubin before the operation of this young patient is relatively high, which is considered to be related to several liver interventional embolization surgeries.

The kidney function is good, the blood qi analysis is also ideal, and the ECMO is running very smoothly. Dr. Charles smiled. Dr. Zheng was really cautious. He even restricted the dosage of low-molecular heparin before the operation, and was constantly observing during the operation.

Although doctors should be cautious, Dr. Zheng was a little too cautious today.

After obtaining the first test report, Zheng Ren ligated and cut off the first branch of the pulmonary artery, that is, the apical anterior artery.

Immediately, the right pulmonary artery trunk was completely exposed and the thick silk thread was blocked.

"Zheng, you're too cautious." Dr. Charles finally couldn't stand it and began to communicate with Zheng Ren.

There is a need to wait here, generally speaking, it is 10 minutes. However, the patient has already taken ECMO, and even if the blood pressure drops due to resection, there will not be too much problem. Just pay attention to rehydration for a long time.

"Doctor, because the patient's liver function is not good, I must be careful." Zheng Ren explained to Dr. Charles why he was careful to observe his blood pressure with the assistance of ECMO.

Zheng Ren's voice in the operating room was mixed with the song of good luck. The others standing on the stage, including Su Yun, did not move, but seemed to be waiting for something.

"Didi~~~" the monitor alarm sounded, and the arterial pressure displayed on it was constantly decreasing.

Dr. Charles does not think it is necessary. As long as the fluid is replenished for a long time, can he stop the surgery because his blood pressure drops after blocking the right pulmonary artery?

It's impossible, so Zheng's waiting is meaningless.

But then Su Yun made a gesture without hesitation. Gu Xiaoran, who was standing beside him, pulled the sterile one-way upwards, retaining the sterile area, exposing the left groin.

What is this to do? Dr. Charles was stunned.

Dr. ICU, who had been prepared, immediately came in from the operating room and pushed a set of strange machines. Xie Yiren handed him a puncture kit, brushed his hands and disinfected it, and he began to operate it.

The machine... made up all the time, and it looked like it had been applied to countless patches, a little shabby and worn. The sound of the monitor alarm sounded in my ears made me feel irritated. It seemed that the singing of good luck was not so pleasant, and they also became impatient.

Dr. Charles did not comment on the machine, he narrowed his eyes and watched Dr. ICU's operation carefully.

The femoral vein puncture sets up a circulation path, and the doctor of the ICU begins to open the machine and connect the pipe.

Adsorb bilirubin and plasma replacement! Dr. Charles quickly discovered the usefulness of this machine. Blood pressure drops, and liver dialysis is needed? Is this operation a little over?

Indeed, hypotension can lead to impairment of renal and liver function, but generally considering the kidney damage will be more serious. Intraoperative dialysis... it seems that this is not necessary.

Could it be that Dr. Zheng had been practicing the operation for a long time and finally lost himself? Dr. Charles guessed in his heart. However, out of respect for the surgeon, he did not express his thoughts on questioning Zheng Ren.

After establishing the liver dialysis channel, Zheng Ren immediately opened the blockade and continued to start the operation. Against the alarm of blood pressure monitoring of invasive artery, he started another methodical operation.

Lin Yuan pulled the lower leaf forward, Zheng Ren and Su Yun began to ligate and cut off the subpulmonary ligament.

Then the mediastinal pleura is pushed open, the inferior pulmonary vein is freed, the conduit is ligated and stitched before being cut off.

Gu Xiaoran pulled the upper lobe lung downward, freed the right main bronchus below the arch of the vein, cut it off 0.5 to 0.8 cm from the tracheal augmentation ridge and sutured it.

No one spoke, and the silent operation was accompanied by a harsh alarm. Even the tacit cooperation of the surgery seemed to be less clear and eye-catching, and became frizzy.

Is this possible? Dr. Charles turned his attention to the monitor and looked at the changes in blood pressure, and felt a little worried. He was worried that the patient's blood pressure would directly lead to cardiac arrest and subsequently lead to the failure of the operation.

Although the blood pressure is still within a range that can be tolerated, it is impossible to say if you don’t replenish the fluid.

"Put heparin 82U/kg, prostaglandin E1 860U/kg, Perferdex fluid anteriorly, the perfusion pressure is 52cm H2O, and the perfusion temperature is 4℃." Zheng Ren said in a deep voice.

"Zheng, do you need to rehydrate?"
