The Moyamoya disease surgery was a success. However, just as Zheng Ren was about to leave, he noticed that the test subject's electrocardiogram began to fluctuate violently. The heart rate instantly reached 120 … 130 … 150 … 180 …
Before Zheng Ren could do anything, the test subject's heart rate plummeted to zero.
Without opening the chest, he performed chest compressions under direct vision. The System notified him that the test subject was dead.
Uh …
Zheng Ren stared at the test subject speechlessly. He was not disappointed, but rather excited.
Although the test subject was dead, the System was telling him that he should first undergo the ECMO and then push the machine to the operating theater for surgery. Alternatively, he could push the patient to the operating theater for the ECMO.
Although it was troublesome, it was the only feasible method.
This also explained why the System had rated the Moyamoya disease bypass surgery as a 50% completion rate.
He just needed to find the reason! He just needed to make improvements in the subsequent surgeries.
Zheng Ren immediately began the next surgery.
First, he started the ECMO on the test subject.
There were two methods of ECMO bypass to adapt to different conditions.
V-V bypass was to draw venous blood through the veins. Oxygen was combined with carbon dioxide and then pumped into another vein.
This method was suitable for patients with lung failure. V-V bypass was a lung replacement method, often used in patients with heart function but lung failure.
It was more commonly used in the respiratory department for extracorporeal support in patients with acute respiratory distress syndrome, acute lung injury, and other respiratory failure. It mainly used the membrane lung system of the ECMO to provide adequate oxygenation for the patient to buy time for the respiratory system to recover.
V-A bypass was to draw venous blood through the veins. Oxygen was combined with carbon dioxide and then pumped into the arteries.
This method was a combined cardiopulmonary replacement method, commonly used in patients with heart failure and cardiopulmonary failure.
If the patient may have prolonged cardiac insufficiency or cardiac arrest, the AA-v pathway can be used. That is, two cannula are drawn from the left and right atrium respectively. The oxygen is combined with the removal of carbon dioxide and then pumped into the artery.
This method could ensure adequate blood flow and prevent thrombosis in the heart and lungs as well as pulmonary edema.
If the patient was conscious, muscle relaxants such as pancuronium or closuccinylcholine, intravenous morphine, and topical lidocaine would be given before intubation.
However, in the System's operating theater, the test subject was under general anesthesia, so Zheng Ren could skip this step.
After administration of heparin 100u/kg, cervical arteriovenous catheterization was performed.
The intubation tube he had chosen was not very thick and could provide 2-3 L/min of blood flow. Incision, direct view of intubation. The intubation tube was not deep and tilted at a certain angle to prevent the pressure of the vertical intubation tube from being too high, leading to rupture and bleeding.
After the insertion, it was confirmed under X-ray. After the intubation was sutured, the tube was fixed.
He connected the machine to the machine and began the Moyamoya disease surgery again.
The surgery went smoothly. This was the 14th training session.
Zeiss's microscope was excellent. Zheng Ren did not experience dizziness or other symptoms like the last time he was training to suture the intestines.
The surgery completion rate was 98%!
Zheng Ren finally heaved a sigh of relief. It should be a success!
However, he did not go back immediately. He had already spent so much time on surgical training. Why not make the surgery perfect?
After another eight surgeries, the completion rate increased by 1% to 99%. The surgery time was reduced by about 30%. He was satisfied with the result.
The next step was to convince the patient's family to carry out the surgery.
If the patient's family was in financial difficulties, they could choose to broadcast the surgery live.
Zheng Ren calmly left the System and returned to the EICU ward.
"Boss Zheng, invite a whole-hospital consultation," Zhao Yunlong suggested. "The neurosurgery department will take a look. If you feel that there's a problem, let them come up with a treatment plan."
"Okay." Zheng Ren nodded.
It was a normal procedure to organize a whole-hospital consultation. This was not a hospital owned by his family. Zheng Ren could not do whatever he wanted like in the System's operating theater.
Actually, it could not be said that he could do whatever he wanted. He could be reasonable outside. However, the System never reasoned with Zheng Ren. The mission was also random and not based on the severity of the patient's condition.
Perhaps in the System's judgment, the patient in front of him was extremely difficult to treat. There was no need to issue a mission at all.
"Little Zhao." As he spoke, Professor Zhang walked in.
"Professor Zhang," Zhao Yunlong replied respectfully.
"The patient's family refuses to fight for it …" Professor Zhang glanced at the patient and saw that the IABP had already been inserted. He could not help but be stunned.
Was it so fast?
When did Zhao Yunlong become so quick in doing things? Yes, he was usually quite quick, but this IABP was too fast.
Professor Zhang then took a look inside the ward. When he saw Zheng Ren, he immediately understood what had happened.
"They refuse to resuscitate him?" Zheng Ren frowned.
"Yes." Professor Zhang nodded and said, "I communicated with the patient's family. The hope is not high, and the cost is still very high. The family cannot afford it, so they decided to give up."
His impression of Zheng Ren was quite good.
Although Professor Zhang had more or less lost face during the surgery for the fish bone and the mediastinal abscess, that was how medicine was. If he could perform the surgery, that was his ability.
As long as one had some understanding of the situation, they would have to admit this.
Professor Zhang did not have any objections to this.
Young people were indeed young people. When it came to resuscitation, they were really hot-blooded. Professor Zhang looked at Zheng Ren, Su Yun, and Zhao Yunlong and thought to himself.
Wasn't he the same when he was young? But now, it had changed. To him, this was just a job.
There was no need to compete with himself for a patient that could not be saved.
Everyone in the ward fell silent at the same time.
Professor Zhang felt that the atmosphere was not right. He said that the patient's family had agreed to give up resuscitation. Shouldn't everyone be relieved?
Why was the atmosphere so depressing?
"Professor Zhang, it's like this," Zheng Ren said. "The patient's situation is rather special, but I think we can still save him."
"You can?" Professor Zhang said in surprise.
The IABP had already been applied, but the patient's heart rate was still not stable. It seemed that the burden on the heart was still too great and it was difficult to maintain.
Based on experience, the patient would soon have heart failure.
With the technical strength of the 912, they could still do this to keep him alive and continuously resuscitate him.
But was there any point in doing this?
Professor Zhang was a little angry.
Young people, in order to show off their skills, they used the patient's life as a sacrifice. How could they do things like this!
He glared at Zheng Ren and said coldly, "Boss Zheng, tell me about the patient's situation."
