Everyone is waiting for Zhou Sheng's next step of medical advice.
However, Zhou Yisheng was like an old monk entering samadhi before, without showing any signs of it.
Time passes minute by minute.
Wang Xiaoming and Cao Xin were both a little anxious.
Wang Xiaoming even thought to himself, it's over, Zhou Yi probably has no experience in dealing with such emergencies. It seems that the operation cannot be carried out today.
Zhou Sheng certainly knows how to deal with this kind of problem.
That's why he has been slow to issue medical advice.
It's because he is waiting for an opportunity.
After five minutes of silence.
Zhou Sheng finally gave the doctor’s order, “Prepare the perfusion solution!”
I heard this doctor's advice.
Everyone immediately understood that Zhou Sheng was going to instill cardioplegia again.
If the first infusion is unsuccessful, try a second time.
Changing doctor's orders may seem trivial, but it is also the simplest and most effective method.
Moreover, Wang Xiaoming and Zhao Feihu also understood why Zhou Sheng had to wait five minutes before issuing this simple medical order.
The two of them can be considered as attending cardiac doctors with some qualifications.
Although during the operation, cardioplegia was never injected a second time.
But there is still a reserve of knowledge about cardioplegia.
They speculated that it must be because Zhou Shengsheng was afraid that too short a time interval between two infusions would cause the potassium ion content in the patient's body to be too high, thus endangering the patient's life.
Wang Xiaoming and Zhao Feihu’s guesses are correct.
The normal value of blood potassium for ordinary people is 3.5-5.5mmol/l.
When the value is higher than 5.5, it is hyperkalemia.
When hyperkalemia exceeds 6, it will cause harm to the human body.
After Jing Xinghai's heart was infused with cardioplegia solution for the first time, it did not stop beating for a long time.
Therefore, the plan given by Zhou Shengsheng was to perform a second perfusion.
However, this second infusion must be started at a suitable time.
Because after the first infusion, the blood potassium content will rise rapidly. In two minutes, the blood potassium will reach a peak value of about 5.5.
At this time, if the second infusion is carried out rashly, the blood potassium will definitely exceed 5.5.
Therefore, Zhou Sheng had to wait for the blood potassium to drop to normal levels before performing a second infusion.
When will blood potassium drop to normal levels?
Zhou Sheng has accumulated rich experience in the copy.
Generally speaking, after blood potassium reaches the peak value of 5.5, it does not last for too long and then drops rapidly. This process takes about two minutes, and finally reaches the normal level in about five minutes.
Therefore, the second infusion can be performed five minutes after the first infusion. Of course, it would be better to wait longer.
But for Jing Xinghai, who has already lowered his body temperature.
It is also very important to stop the heart as early as possible and start the operation as early as possible.
As soon as five minutes passed, Zhou Yisheng immediately gave the doctor's order.
The instrument nurse immediately prepared the perfusate again.
Zhou Sheng took over the perfusion solution and pushed the high-potassium perfusion solution from the perfusion cannula into Jing Xinghai's heart again.
Next, everyone in the operating room, including Zhou Shengsheng, was waiting for the results of the perfusion.
Generally speaking, based on Zhou Yisheng’s experience.
In this situation where the cardiac arrest is not smooth, as long as the cardioplegia solution is re-infused, basically 90% of the problems will be solved.
Under the expectant gazes of everyone, Jing Xinghai's vibrant heart stopped again.
And this time, it seemed that the stopping of the heart was really successful. After two or three minutes, the heart was still quiet.
Seeing the situation in front of them, Wang Xiaoming and Cao Xin smiled.
Zhao Feihu's eyes also lit up.
He thought, Hey, this week has been good. Such a difficult problem can be solved by just re-injecting the cardioplegia. And he seems to know the time of the second infusion. It seems that this kid really has two ideas.
Take the brush.
Zhou Yisheng had no time to care about other people's thoughts. He carefully observed Jing Xinghai's heart for a while.
Confirm that it is finally honest.
Zhou Sheng raised his head to greet the nurse and handed him the electric knife. He was going to remove Jing Xinghai's tumor.
"Electric knife!"
Zhou Shengsheng's words had just finished.
The equipment nurse, who was always quick in her movements, did not act immediately.
Zhou Sheng was a little strange. He glanced at the equipment nurse and gave the doctor's order again.
"Electric knife!"
At this time, the equipment nurse said timidly: "Dr. Zhou...it seems that there is something wrong with his heart."
After Zhou Sheng heard this, his heart sank suddenly.
He immediately looked down.
Suddenly, Zhou Yisheng felt bad all over.
I saw that my heart, which was peaceful just now, suddenly began to vibrate abnormally again. The posture was like a beast that had just been tamed, roaring restlessly.
Although at this moment, it has not jumped again immediately, but it seems to be only a matter of time.
The second infusion still had poor results.
This made Zhou Yisheng frown.
For a moment, Zhou Yisheng had the illusion that he was not undergoing surgery in reality, but in a copy.
This surgery seemed to be done deliberately to make things difficult for me.
We have to force out Zhou Yisheng's little universe.
Zhou Sheng thought to himself.
Interesting!
I didn't expect that such a thing would happen in reality. It seems that those unexpected situations in the previous dungeons were not created out of thin air.
I met it today.
Zhou Shengsheng's eyebrows rose, and his eyes became more alert.
He did not lose confidence, on the contrary, he became more motivated.
Thousands of difficult surgeries not only honed Zhou Yisheng's skills, but also honed his will.
Zhou Yisheng is still very capable of fighting.
However, as the first assistant at this moment, Wang Xiaoming was a little confused.
He asked Zhou Yisheng: "Dr. Zhou, what's wrong? Is the perfusion volume insufficient?"
Zhou Sheng shook his head and said: "The perfusion volume is sufficient. Moreover, the second perfusion has been carried out in such a short period of time. No matter how insufficient it is, the two volumes combined greatly exceed the normal perfusion volume."
Wang Xiaoming asked anxiously: "Is the potassium concentration of the perfusion solution too low?"
As soon as Wang Xiaoming said these words.
On the side, Zhao Feihu also nodded frequently, and he also fully agreed with Wang Xiaoming's inference.
But Zhou Sheng didn't think so.
Because of the help of the auxiliary system.
Changes in blood potassium levels in Jing Xinghai’s body.
He can be seen at all times.
While he was speaking, Jing Xinghai's blood potassium level had reached the peak value after the perfusion.
It is close to the human body’s limit of 5.5mmol/l.
If the potassium concentration of the perfusate is insufficient, it is impossible to achieve this value.
But since Wang Xiaoming raised this suspicion.
There is no proof for what he said. Of course, Zhou Sheng must handle it according to the process.
He immediately gave the doctor's order and said: "Then do a blood potassium test. Get a syringe!"
