Zheng Ren performed a mattress suturing on the epineurium at the front of the ascending aorta and put it into the hemostat.

After that, he injected the needle with the freezing heart hemostasis spray, drained the air, and inserted it into the central part of the mattress suture thread into the ascending aorta.

He tightened the hemostat and fixed the tracheal tube and the hemostat together with a thick thread. He connected the tube to the perfusion device.

“Boss Zheng? What’s our next step?” Old he asked in advance.

“Left room.”

“Alright,”

There were two options for the next step of the surgery.

It was either left atrial drainage or left cardiac drainage.

There were no advantages or disadvantages, only whether it was suitable or not. For a cardiopulmonary bypass specialist, left octocytic drainage and left cardiac drainage were slightly different. Old he was showing off his professional details to boss Zheng.

I’m definitely more suitable than the beautiful twin sisters! Boss Zheng, look at me, look at me!

Look here, look here!

Zheng Ren could not hear the cry in old he’s heart. He only felt that the surgery was much smoother than being alone in the system operating theater.

He made a mattress suture on the connection between the root of the vein in the right lung and the left atrium and put a hemostat on it.

After making a small incision in the mattress – style suture circle, he inserted the left atrial drainage tube into the left atrium. He tightened the hemostat and tied it with thick silk threads to fix the drainage tube and the hemostat together. He then connected the drainage tube to the artificial cardiopulmonary machine.

After completing all the operations, Zheng Ren checked all the pipes and their connections again to make sure that there were no mistakes. After making sure that there were no obstacles in each channel, he began the cardiopulmonary bypass.

The moment old he started the cardiopulmonary bypass, his hand speed increased rapidly.

Although he knew that he was already firmly in first place, he wanted to leave behind a number that no one could surpass.

In the past, he had not performed many cardiovascular surgeries in the 912 Emergency Medical Center, and the standard of the surgeons was average, so old he did not have any status in the group.

Although it was just a chat group, those with high skill had a certain level of authority.

People in the technical field all had similar problems. Even though it was just a chat group, it was still common.

Old he glanced at the timer from time to time.

However, it was completely meaningless to argue about this, and it was completely different from the heart bypass surgery that was still in the process of stopping the heart.

However, even if cardiopulmonary bypass was withdrawn from the historical stage in the future, he would still be considered to have left a record in the domestic surgical world … Or even in the global surgical world!

5′05″!

When he saw the number, he was a little dazed.

The previous record was 9 ‘ 22 “, but boss Zheng’s surgery had actually increased the time required to establish the external circulation by nearly double!

What the f * ck, is this something a human would do?

After old he saw the time, he clenched his right fist and waved it.

It’s done, this is definitely a world record!

Although no one acknowledged it, in his heart, this was a world record!

He would show off in the group after the surgery, but for now, he should focus on providing boss Zheng with a TV station. He had to leave a good impression on boss Zheng.

Don’t be careless and waste all your efforts.

‘The twin sisters are such powerful opponents. I’m under a lot of pressure.’ Old he carefully observed the progress of Zheng Ren’s surgery from the patient’s head.

After a few minutes of cardiopulmonary bypass, Zheng Ren blocked the superior and inferior vena cava and entered complete cardiopulmonary circulation.

At this time, the blood from the upper and inferior vena cava had completely flowed into the artificial cardiopulmonary machine through the intubation and did not flow into the right atrium.

At the same time, he lowered the temperature of his blood.

Old he kept reporting the blood temperature.

36℃……

35℃……

32℃……

When his body temperature dropped to 30°C, Zheng Ren lifted the ascending aorta dressing and used the aortic dissection forceps to block the ascending aorta.

Su Yun immediately used the infusion tube at the main artery’s root to administer 4 degrees cardiac arrest. At the same time, Zhao Yunlong used frozen saline or ice shards at 4°C on the surface of the heart to lower the temperature, allowing the heart to rapidly stop beating.

Zheng Ren was very satisfied.

It was indeed much faster than the surgery speed in the system operating theater.

He had two assistants who were capable enough to be the chief surgeon for type 1 aortic repair surgery, an anesthetist like old he who could administer anesthetics and perform cardiopulmonary bypass, and most importantly, Yiren was there.

Not to mention anything else, little Yiren’s eyes curved into crescents as she smiled. The fatigue from not sleeping the entire night and only catching up on sleep on the plane was swept away.

In comparison, the experience in the operating theater of the system was extremely bad.

After blocking the ascending aorta, old he focused his attention and began to report various values.

Cardiopulmonary bypass was very difficult. If the patient was not careful, he would not wake up.

“Arterial pressure, 70 mm HCG.”

“Central venous pressure is 9cm of water.”

“Body temperature, 27 degrees Celsius.”

“Old he, lower your body temperature a little more.” Zheng Ren lowered his head to look at the operating area while he communicated with old he.

Under normal circumstances, a person’s body temperature would be maintained at around 28 degrees Celsius under cardiopulmonary bypass.

However, if the surgeon judged that the operation was very difficult and the operation process was particularly long, the cardiopulmonary bypass specialist would have to lower the body temperature further.

“How much?” Old he asked.

“Deep freeze, 15 degrees Celsius.” Zheng Ren said.

Old he was shocked.

The cardiac arrest fluid can cause cardiac arrest and quickly stop all biological and mechanical activities of the heart, which is beneficial for preserving the heart’s energy reserve.

Supplemented by local heart ultra – Low temperature, it could further reduce the consumption of cardiac energy and oxygen, and reduce the accumulation of harmful substances such as carbon dioxide, hydrogen ions, and oxygen free groups.

The low temperature meant that the surgery would take more than three hours.

He immediately started operating the device to lower the temperature.

“Heart muscle temperature, 15 degrees Celsius,” Old he said.

“That’s enough,”

“Flow, 50 – 60ml/kg.”

“Old he, take a look at the blood and Qi Value.” Zheng Ren held a pair of blunt scissors in his hand and began to separate the pulmonary artery segment as he conversed with old he.

His words did not delay Zheng Ren’s operation, and the surgery was done quite meticulously.

After the cardiopulmonary bypass was activated, the patient’s body temperature dropped below 25 degrees Celsius, and the heart muscle temperature also dropped to 15 degrees Celsius. Zheng Ren first observed the patient’s coronary arteries.

Since there was no problem with his coronary artery, Zheng Ren started to drift away from the pulmonary artery.

The pulmonary valve was located between the right ventricle and the pulmonary artery, and it prevented blood from flowing back to the right ventricle after entering the pulmonary artery.

The heart had two ventricular valves and two aorta valves.

The pulmonary artery valve was one of the 3 and a half Moon shaped valves. The valve and the valve ring were relatively weak. The valve ring was connected to the muscles of the right ventricle funnel and was not directly connected to the tristepper by fiber.

It was time for the main event. Zheng Ren paused for a moment, took a deep breath, held his breath, and began to cut open the pulmonary artery. At the junction of the left and right petals.

Zheng Ren was especially careful when he was cutting down. He was more careful than he had ever been.

He knew that if he cut through the pulmonary artery wall, he might hurt the aorta. Moreover, the wound was very deep and it would be difficult to stop the bleeding.

He gently tapped the wound with his lancets and used the hemostatic forceps to separate the wound layer by layer.

It was still the smallest hemostatic forceps. Zheng Ren’s fingers could not reach in, so he could only touch it.

He still did not use the microscope.

At that moment, the assistant was relatively free. However, Su Yun did not say anything. She was focused on Zheng Ren separating the pulmonary artery.
