The patient's heart rate and blood pressure continue to drop, and he may have a cardiac arrest at any time, and time waits for no one.

Chen Qi quickly ran to the General Affairs Department and asked them to set up a tent in the backyard as quickly as possible.

Ask, why not perform surgery in the operating room? The answer is: the radiation from interventional surgery is too great and can easily cause damage to the precision instruments in the operating room.

This reason is okay, because whether it is X-ray or CT\MR, a dedicated room is required for radiation isolation. If you really have to destroy several computers, you will have no place to cry.

Chen Qi then directed the logistics staff to carry out a small X-ray machine from a warehouse, which was about the size of a desk.

Question: When did the People's Hospital have this kind of small X-ray machine? The answer is: employees should stop asking questions about leadership matters.

In short, Chen Qi's preparation for this interventional surgery was very low-key. Not only did the medical staff in the emergency department be required to keep it confidential, but even the doctors at Xijing Hospital were not allowed to watch.

Why don't you just watch?

They are professionals, and all of them are professors and associate professors. They are old people. They are not as easy to fool as young people like Yi Zewen, Chen Li and others, so I will not show them.

Of course, the obvious excuse is: interventional surgery radiates too much and has a great impact on health. For the safety of my friends, I refuse to watch.

Professor Tong was not convinced at first, thinking that it would not matter if he took some radiation when he was old.

But when Chen Qi said that the amount of radiation in one hour is equivalent to the amount of radiation in 1,000 X-rays, the old man was immediately taken away by his disciples.

The tent operating room is set up quickly and can be used after being disinfected.

Cardiac interventional surgery does not have high requirements for a sterile environment, because this kind of surgery does not require dissection, and only requires a pinhole in the wrist or the inside of the leg. This is why Chen Qi dared to be confident in such a temporary tent.

The reason for the surgery.

When Yi Zewen and Chen Li came in, they looked around curiously.

Both of them had worked with Chen Qi in Africa for two years. They were no strangers to the tents of field hospitals, and they felt right at home.

"Dean, it's like we were back in Africa, doing surgery in a tent."

"The conditions are better than those in Africa. The land in Africa is all mud, but here we have cement."

Chen Qi struggled to take out a few pieces of lead clothing from the box:

"Come on, this surgery is special. The radiation will be serious. For your health, put on the lead suit."

Yi Zewen and Chen Li casually reached for the lead clothes with one hand, but suddenly they lost their grip and the lead clothes fell to the ground.

Yi Zewen picked it up in surprise and thought about it: "Dean, this lead coat is not light, it weighs more than 20 kilograms, doesn't it?"

Chen Qi laughed out loud when he saw his two subordinates making a fool of themselves:

"One piece of clothing weighs 30 pounds. This is specially made. Don't take it off while you're wearing it. Otherwise, don't blame me if you can't have children in the future."

It doesn't matter that Yi Zewen is already married and has children, but Chen Li is a little scared as she is still an unmarried girl.

And she tried it, but the 30-pound lead suit couldn't last long on her body, so she was sweating profusely.

Chen Qi felt a little sorry for his two subordinates. He wanted to show his authority, but he had to bring down the entire team. Even if he was the dean, he felt a little embarrassed.

"Let's do this. Lao Yi will be operating with me in a while. Chen Li, you can leave after preparing all the surgical instruments. The little girl can't stand wearing a lead suit."

Chen Li is 160cm tall and weighs only 45kg. The 15kg lead suit is overloaded for the little girl.

But Chen Li still gritted her teeth: "No, Dean, let's start the operation."

Chen Qi looked at the strong little girl and nodded slightly, thinking that when she grows up for a few more years, she will be promoted to head nurse.

It was Yi Zewen's first experience with "cardiac interventional surgery", so he didn't know anything about how to operate it.

"Let's not perform surgery first. Let's do an arteriogram first to check which part of the heart is blocked and narrowed, and then we can place a stent. Please bring the patient in."

Cui Tongzhi felt that he was about to die. It turned out to be just abdominal pain, but now his chest was also tight, and he felt like he was on the verge of death.

"Dean Chen, save me!"

At this time, Cui Tongzhi's heartbeat had dropped to 40 beats per minute, and his consciousness began to become a little blurry. The situation was already very critical.

Chen Qi nodded heavily: "Don't talk, relax. I have everything, so you can't die!"

Cui Tongzhi's tears came out immediately after rinsing them. Since ancient times, who wants to die?

Chen Qi looked at Yi Zewen and Chen Li: "Are you all ready?"

"Ready!"

Chen Qi shouted outside the tent again: "The X-ray machine will be turned on soon. Everyone should stay away from more than 20 meters and are not allowed to approach. People from the security department are responsible for guarding."

Afterwards, Chen Qi directly turned on the switch of the angiography X-ray machine. This piece of black technology from later generations is digitally controlled throughout the process and does not require too much operation by the surgeon.

After Yi Zewen fully disinfected and local anesthetized the patient's wrist joint, Chen Qi directly took out a vascular puncture needle, touched the patient's radial artery and inserted it. After inserting it in place, he began to place a guide wire inside.

Yi Zewen was a little curious:

"Dean Chen, is this guide wire made of metal? If it is inserted into the blood vessel like this, will it cause accidental damage to the blood vessel if I am not careful?"

Chen Qi gently placed the guide wire while looking at the X-ray display:

"It will not damage blood vessels. This kind of guide wire is made of special materials. When it encounters liquid, it becomes slippery and very flexible."

Chen Li also asked curiously: "If the guide wire is in the blood vessel, will the patient feel pain?"

"It won't hurt, because there are no nerves in the blood vessels, so the patient can't feel it. This is one of the reasons why general anesthesia is not performed."

Under the guidance of the X-ray monitor, the position of the guide wire reached the aortic root and did not penetrate into the heart.

At this time, Chen Qi replaced an angiography catheter and used the guide wire as a track. The contrast medium catheter was placed retrograde along the artery in the coronary sinus and aligned with the coronary artery opening.

Chen Qi then reminded:

"Okay, now that the catheter is in place, I'm going to inject the contrast agent. You will be able to see which blood vessel is blocked in a while. Remember that position. We will also place the stent later."

Yi Zewen nodded repeatedly and looked at the screen without blinking.

At this time, you can see on the display that the blood vessels of the heart are like branches with different branches, appearing from time to time as the heart pumps blood.

Where the blood vessels are suddenly interrupted or become smaller, it means that the blood vessels in that part are blocked or infarcted, and it is clear at a glance.

Suddenly Yi Zewen shouted excitedly: "I saw it, right here, the proximal segment of the right coronary artery is occluded."

Chen Qi glanced at Yi Zewen with relief.

Although this was Yi Zewen's first time exposed to interventional surgery and the first time he had seen this kind of two-dimensional vascular image, his ability to quickly prepare and tell the location of vascular occlusion shows that Yi Zewen's anatomy skills are very solid and he is indeed a usable doctor.

Talent.

"Okay, now that we have found the blockage, the next clinical idea is very simple. Since you have a blockage here, I will install a stent for you to open up the blockage and the blood vessels will

Once it is unblocked, the myocardial infarction will be cured, right?"

Yi Zewen nodded excitedly after hearing this,

"I understand. It turns out that this is the secret of interventional surgery. It is simple and the effect is immediate. So how do you put the stent in next?"

Chen Qi took out a liquid metal stent from a small and precise box, which was quite emotional.

In his previous life, there was just such a bracket, worth about 28,000 yuan, an absolute high-tech product.

However, this kind of good thing has been ruined by a few unscrupulous doctors because the kickbacks are huge.

A bracket costs 10,000 to 30,000 yuan, and the rebate may range from 1,000 to 5,000 yuan. What consequences will this lead to?

There is only one narrow or occluded place, and it can be solved by installing a stent, but the doctor exaggerates and says that this is a problem or that is troublesome. Why will someone die if it is not done correctly?

What should we do? Install more brackets.

The family members nodded obediently and went home to borrow money to save their lives, but the doctor got a lot of kickbacks.

Although there are only a few such doctors, it is these few black doctors who spoil the whole pot of porridge like a mouse, causing the people and public opinion to be black all the way when they encounter doctors.

Later, the higher authorities also learned about this drawback, so they began to impose restrictions on imported stents, either restricting your bidding or restricting your medical insurance reimbursement, hoping that everyone would use domestic stents.

There is definitely a difference between the quality of domestic stents and imported stents, but the difference is not big. After all, they are more than half cheaper.

But sometimes good intentions lead to bad things. Why do you say that?

The imported brackets cost tens of thousands of yuan each, but they won’t be used.

Okay, if you use a domestically produced stent, you can accept it for a few thousand yuan, but the relevant departments forcefully raise the price to a few hundred yuan.

The purpose is to benefit patients and reduce their burden, and the starting point is definitely good.

But when it comes to medical devices, you get what you pay for, and the cheaper the better.

If you lower the price to such a low level, the manufacturer's profit will be gone, so how can they still use the best materials for you? They will definitely cut corners, just like cutting down on parts of a car.

In the end, it is the patient who suffers, because the patient takes the stent to save his life and wants to live a few more years.

If the quality of the stent is not up to standard, the disease will still occur after a few years, and the patient may die directly.

Or if it doesn't die, the stent needs to be replaced, which costs a lot of money. Do you think the patient will save money or not?

To use an internet slang:

For expensive things, you feel distressed the moment you pay for them, and you feel happy every day when you use them. It feels so worth it!

Cheap things are only happy the moment you buy them, not the whole day when you use them.

Therefore, the domestic medical market is really in chaos as soon as it is released, and it dies as soon as it is controlled, which makes people extremely helpless.
