Doctor Peerless

Chapter 765 Second Perfusion
Zhou Yisheng's doctor's order came belatedly.

It can be said that it is highly anticipated.

Unexpected surgical situation.

It made everyone in the operating room look helpless.

All eyes were on Zhou Sheng.

Everyone is waiting for Zhou Sheng's next doctor's order.

However, before Zhou Sheng was like an old monk in meditation, he didn't show the slightest sign.

Time passed by minute by minute.

Both Wang Xiaoming and Cao Xin were a little anxious.

Wang Xiaoming even thought to himself, it's over, probably Zhou Zhou has no experience in dealing with such emergencies in his life.It seems that the operation cannot be carried out today.

Of course Zhou Sheng knew how to deal with this kind of problem.

The reason why he has been slow to give a doctor's order.

It was because he was waiting for an opportunity.

After a minute of silence.

Zhou Sheng finally gave the doctor's order, "Prepare the perfusion solution!"

Hear this doctor's order.

Everyone immediately understood that Zhou Sheng wanted to infuse cardioplegia again.

If the first infusion is unsuccessful, then a second time will come.

Changing a doctor's order may seem trivial, but it is also the simplest and most effective way.

Moreover, Wang Xiaoming and Zhao Feihu also understood why Zhou Sheng had to wait 5 minutes for this simple doctor's order to be issued.

The two of them could be regarded as attending cardiologists with some qualifications.

Although during the operation, cardioplegia was never perfused twice.

However, there is still a reserve of knowledge about cardioplegia.

They speculated that it must be because Zhou Sheng was afraid that the interval between two infusions would be too short to make the potassium ion content in the patient's body too high, which would endanger the patient's life.

Wang Xiaoming and Zhao Feihu's guess was 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 injected with cardioplegia for the first time, it did not stop for a long time.

So the plan given by Zhou Sheng is to perform a second perfusion.

However, for this second perfusion, an appropriate time must be chosen to start.

Because after the first perfusion, the blood potassium content will rise rapidly, and in 2 minutes, the blood potassium will reach a peak value of about 5.5.

At this time, if the second perfusion 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 a normal level before performing a second perfusion.

When will blood potassium drop to normal levels.

Zhou Sheng has already accumulated a wealth of experience in dungeons.

Generally speaking, after blood potassium reaches the peak value of 5.5, it will not last for too long, and then it will drop rapidly. This process is about 2 minutes, and finally reaches the normal level in about 5 minutes.

Therefore, the second perfusion can only be performed 5 minutes after the first perfusion.Of course it's better to wait longer.

But for Jing Xinghai who had lowered his body temperature.

It is also very important to stop the heart earlier and start the operation earlier.

After 5 minutes, Zhou Sheng immediately issued a doctor's order.

The instrument nurse immediately prepares the perfusate again.

Zhou Sheng received the perfusate, and pushed the perfusate containing high potassium from the perfusion cannula into Jing Xinghai's heart again.

Next, everyone in the operating room, including Zhou Shengsheng, was waiting for the result of the perfusion.

Generally speaking, based on Zhou Sheng's experience.

In the case of unsatisfactory cardiac arrest, as long as the cardioplegic fluid is reperfused, basically 90% of the problems will be solved.

Under the expectant eyes of everyone, Jing Xinghai's vigorous heart stopped again.

And this time the stop seems to have really succeeded.After two or three minutes, my heart was still quiet.

Seeing the situation in front of them, Wang Xiaoming and Cao Xin smiled.

Zhao Feihu's eyes also brightened.

He thought, Yo, life is good this week, such a difficult problem, just refilling with cardioplegic fluid can solve it.Moreover, he seemed to be very clear about the time of the second infusion.It seems that this kid really has two brushes.

Zhou Yi had no time to care about other people's thoughts, so he carefully observed Jing Xinghai's heart for a while.

Make sure it's finally honest.

Zhou Sheng raised his head to greet the nurse to hand over the electric knife, and he was going to perform tumor resection for Jing Xinghai.

"Electric knife!"

Zhou Sheng's voice just fell.

The equipment nurse, who has always been quick to move, 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: "Doctor Zhou... It seems that there is something wrong with his heart."

Zhou Sheng's heart sank when he heard this.

He immediately looked down.

Immediately, Zhou Sheng felt bad all over.

I saw that the heart, which was still quiet just now, began to vibrate abnormally again in an instant. The posture was like a beast that had just been tamed, roaring restlessly on the ground.

Although at this moment, it has not jumped back immediately.But that also looks like a matter of time.

The second perfusion is still not effective.

This made Zhou Sheng frowned.

For a moment, Zhou Sheng had the illusion that he was not performing the operation in reality, but in the dungeon.

This operation seems to be deliberately trying to make things difficult for myself.

He had to force out Zhou Sheng's small universe.

Zhou Sheng thought to himself.

interesting!
Didn't expect this kind of thing to happen in reality.It seems that the emergencies in the previous dungeons are not considered out of thin air.

I met it today.

Zhou Yisheng raised his eyebrows, and his eyes became more energetic.

He didn't lose confidence, on the contrary, he was full of fighting spirit.

Thousands of difficult operations not only honed Zhou Sheng's skills, but also honed his will.

Zhou Sheng was still full of fighting power.

However, at this moment, Wang Xiaoming, who is the first assistant, is already a bit confused.

He asked Zhou Sheng: "Doctor Zhou, what's the matter? Is the perfusion insufficient?"

Zhou Sheng shook his head and said, "The amount of infusion is sufficient. And in such a short period of time, the second infusion has already been carried out. No matter how insufficient it is, the sum of the two amounts greatly exceeds the normal infusion amount."

Wang Xiaoming asked anxiously, "Is that because the potassium concentration of the perfusate is too low?"

As soon as Wang Xiaoming said this.

On the side, Zhao Feihu also nodded frequently, and he also very much approved of Wang Xiaoming's inference.

But Zhou Sheng didn't think so.

Because of the help of the auxiliary system.

Jing Xinghai's blood potassium levels changed.

He is visible all the time.

While speaking, Jing Xinghai's blood potassium level had already reached the peak after infusion.

It is close to the limit of human body 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 doubt.

There is no basis for saying it, Zhou Sheng must of course deal with it according to the procedure.

He immediately issued a doctor's order and said, "Then do a blood potassium test. Get a syringe!"
