Boss Li said it was a little cold.

Monday called the roving nurse here and added a towel to Boss Li to cover his legs.

A towel doesn't do much either.

However, Boss Li felt a little warmer.

The role of human psychology is sometimes very large.

Just like in the operating room, the doctor and the patient feel completely different about the cold.

Doctors often don't feel much cold.

And patients often feel a little cold.

It didn't take long for Su Quan and Cao Xin to prepare anesthesia.

The two returned to the operating table.

Then it's time for surgery.

Monday also ended chatting with Boss Li at this time.

Cao Xin was holding the anesthetic needle, but he hadn't gotten the needle yet.

Before the surgery, Monday had already had a simple preoperative meeting.

He also knew that the approach point for this PCI surgery was the patient's right radial artery.

But he was a little nervous, and he didn't dare to do it casually without Zhou Yisheng's medical advice.

Monday is very caring, and not much to say.

He directly began to disinfect the operation of Boss Li's bare right arm.

After the disinfection is completed.

Monday signaled to Cao Xin that it was okay.

On Monday, the service had already arrived at home, and even the place where the injections were given was disinfected.

Originally, this disinfection work should have been done by Cao Xin himself.

At this time, Cao Xin only has the job of injection.

Local anesthesia, often used in emergency departments.

Cao Xin also practices a lot these days, and the technique is still okay.

At that moment, Cao Xin began to give Boss Li a local anesthetic for his right arm.

In minutes, the anesthesia has an effect.

Start on Monday.

In PCI intervention, the area to be treated is the blood vessels in the heart.

But miraculously, the approach point of this surgery is in the blood vessels of the arm.

Sometimes, of course, it can even be accessed from the blood vessels of the legs.

The principle of this, of course, is that the blood vessels are all figured out.

Through the blood vessels in these areas, the treated stent material is delivered to the location of the heart blood vessels. This is a groundbreaking treatment that has saved thousands of patients with heart attacks, thus avoiding the pain of open chest.

As Boss Li said, this surgery was first invented by Dr. GT in the 70s.

Now on Monday, I want to pay tribute to him.

And with the help of modern technology and the help of the system, Zhou Yi is confident to do better.

On Monday, the auxiliary was turned on and the surgery began.

Zhou Zhou first pinpointed the radial artery in Boss Li's right arm, and first cut a small wound with a skin-breaking knife.

Then he said in a deep voice: "Piercing needle!"

The instrument nurse handed it over immediately.

Monday carefully punctures the blood vessels with a needle.

As with intravenous drip, whether the needle punctures the blood vessel accurately or not depends directly on the blood return in the needle.

If there is blood return, the puncture is successful.

There is no blood return, it is punctured into the muscle.

There is certainly no difficulty in doing this kind of piercing on Monday.

One needle goes down, and the blood return is directly seen.

After successful puncture, the next step is to send the puncture guidewire for positioning.

The puncture guidewire is in place.

At this point, the needle is withdrawn, and a tube is inserted along the needle wire.

After the tube is placed, the positioning of the puncture guidewire is useless and removed.

The tube is left behind, which is equivalent to creating a working channel in the blood vessels of the right arm.

Puncture, lower guidewire positioning, cannula.

This is a common routine for many endoscopic surgeries, and Zhou Shengsheng is skillfully played.

When the pathway is established, it is equivalent to creating a temporary open door on the blood vessel.

This is also the easiest part of PCI surgery.

Next, it is necessary to pass through this door and carry out difficult operations to make Boss Li's blood vessels clear under the X-ray machine.

The X-ray machine is not an auxiliary system for Monday, and there is no way to see the normal blood vessels.

In this case, a contrast agent is used.

A very thin guidewire is operated on Monday through a complex vascular pathway, retrograde from the radial artery of the right arm to the great vessels of the heart.

Once the guidewire is positioned, a catheter is fed along the guidewire.

A catheter is fed into a blood vessel and a contrast agent can be delivered in real time.

With the help of contrast media, the thickness and direction of Boss Li's blood vessels, as well as the location of the blocked blood vessels, are clearly visible under the X-ray machine.

Now, the preliminary work for the PCI procedure is fully completed.

The blood vessels in question are already exposed in their original form in the computer monitor connected to the X-ray machine.

The next step is to deal with the problem of blood vessels.

On Monday, the imaging catheter was removed and another catheter was inserted.

The catheter in front is called an imaging catheter.

At this point, a guide catheter is fed.

The biggest difference between the two is that the contrast catheter is thinner and the guide catheter is thicker.

This is normal, at the beginning, there was no imaging, the condition of the blood vessels and the location of the lesion were not clear, with a thin insurance, the injection of contrast agent did not use too thick tubes.

Now, with imaging, the blood vessels are clearly visible in the display.

Although this X-ray, there is no Zhou Life's auxiliary system.

But it can be regarded as a plug-in for today's medical technology.

Therefore, PCI surgery must be performed in the environment of an X-ray machine.

Of course, there is an auxiliary system on Monday, and without X-ray machine and imaging, he can also know exactly the location of the diseased blood vessel and the condition of the blood vessel.

But the operation is not his own, and the process still has to be followed.

Next, Zhou Zhou barely looked at the blood vessels on the X-ray monitor, and directly used his ability to "see through" the patient's body at a glance to operate the guide catheter through Boss Li's blood vessels.

Wait until you reach the diseased blood vessels.

PCI surgery has been almost half successful.

The next step is to place the stent through the guide catheter.

The whole operation, Zhou Yi operated, it was handy.

This kind of minimally invasive surgery is even more vividly exerted by the powerful auxiliary system of Zhou Yi.

If it weren't for the presence of Bai Mingming and others.

He can even do this without looking at the X-ray machine.

An hour later.

A metal mesh stent remained in Boss Li's veins.

On Monday, the catheter was carefully withdrawn.

The next step is to dismantle the "door" left on Boss Li's right arm.

It's not that difficult.

Nor will there be a danger to life.

Minimally invasive surgery, the wound is very small, and no stitches are required, which is a wound treatment work.

Monday made Bai Mingming work for the Ming Dynasty.

Bai Mingming's trip this time was mainly to learn the PCI puncture technique on Monday.

After watching it for a long time, he has gained a lot.

At this time, he was also generous, and he gave up the work of "breaking down the door" to Su Quan and Cao Xin.
