Zhou Sheng called the circulating nurse and gave Boss Li a towel to cover his legs.
A towel is not of much use.
But Boss Li feels a little warmer.
The role of human psychology is sometimes very powerful.
Just like in the operating room, doctors and patients have completely different feelings about cold.
Doctors often don't feel cold very much.
Patients often feel a little cold.
Not long after, Su Quan and Cao Xin had prepared anesthesia.
The two returned to the operating table.
Next it's time for surgery.
Zhou Sheng also ended his chat with Boss Li at this time.
Cao Xin held the anesthesia needle but had not yet injected it.
Before the operation, Zhou Sheng had already held a simple pre-operative meeting.
He also knew that the access point for this PCI surgery was the patient's right radial artery.
But he was a little nervous. He didn't dare to do anything without Zhou Sheng's medical advice.
Zhou Sheng is very considerate and doesn't talk too much.
He directly began to disinfect Boss Li's exposed right arm surgery site.
After disinfection is completed.
Zhou Shengsheng signaled to Cao Xin that it was okay.
This service has been provided to everyone on Monday, and even the injection area has been disinfected.
Originally, Cao Xin should have done the disinfection work himself.
Now, Cao Xin only had the job of giving injections.
Local anesthesia is often used in emergencies.
Cao Xin has been practicing regularly these days, and his skills are still good.
At that moment, Cao Xin began to give local anesthesia to Boss Li’s right arm.
Within minutes, the anesthesia takes effect.
Started on Monday.
During PCI interventional surgery, the site to be treated is the blood vessels in the heart.
But the amazing thing is that the entry point for this surgery is the blood vessel in the arm.
Of course, sometimes it is even possible to access the blood vessels in the legs.
The principle behind this is, of course, that blood vessels are all connected.
Through the blood vessels in these parts, the therapeutic stent material is delivered bit by bit to the location of the heart blood vessels. This is a groundbreaking treatment method that has allowed thousands of myocardial infarction patients to avoid the pain of thoracotomy.
As Boss Li said, this surgery was first invented by Dr. Gt in the 1970s.
Now that Zhou Yisheng is alive, I want to pay tribute to him.
And with the help of modern technology and systematic help, Zhou Yisheng is confident to do better.
Turn on the auxiliary on Monday and start the surgery.
Zhou Shengsheng first found the radial artery in Boss Li's right arm and made a small incision with a skin knife.
Then he said in a deep voice: "Puncture needle!"
The nurse immediately handed over the equipment.
Zhou Sheng carefully used the puncture needle to puncture the blood vessel.
Just like intravenous drip, whether the needle punctures the blood vessel accurately or not depends directly on the blood return in the needle tube.
If blood returns, the puncture is successful.
If there is no blood return, it means the muscle has been punctured.
There is definitely no difficulty in doing this kind of puncture on Monday.
After one injection, you can directly see the blood returning.
After the puncture is successful, the next step is to insert the puncture guidewire for positioning.
The puncture guidewire is in place.
At this time, pull out the puncture needle, insert a tube along the puncture guide wire.
After the tube is placed, the positioned puncture guide wire is useless and must be removed.
The tube is left, which is equivalent to establishing a working channel in the blood vessels of the right arm.
Puncture, guide wire positioning, and cannulation.
This is a common routine used in many endoscopic surgeries, and Zhou Yisheng is very skilled at it.
Once the access is established, it is equivalent to establishing a temporarily open door on the blood vessel.
Building the gate is still the easiest part of the PCI surgery.
Next, we have to go through this door and perform a difficult operation to make Boss Li's blood vessels clear under the X-ray machine.
The X-ray machine is not an auxiliary system for Zhou Sheng. There is no way to see normal blood vessels clearly.
In this case, contrast agent must be used.
Zhou Sheng operated an extremely thin guidewire and passed it retrograde from the radial artery in the right arm to the great blood vessel of the heart through a complex vascular path.
After the guide wire is positioned, a catheter is inserted along the guide wire.
The catheter inserted into the blood vessel can deliver contrast agent in real time.
With the help of the contrast agent, the thickness and direction of Boss Li's blood vessels, as well as the location of the blocked blood vessels, were clearly visible under the X-ray machine.
Now, the preliminary work of PCI surgery is completely completed.
The blood vessels in question were revealed on the computer monitor connected to the X-ray machine.
The next step is to deal with the blood vessel problem.
Zhou Sheng pulled out the catheter used for angiography and inserted another catheter.
The catheter in front is called the contrast catheter.
At this time, the guiding catheter is inserted.
The biggest difference between the two is that the imaging catheter is thinner and the guiding catheter is thicker.
This is normal. At the beginning, there is no contrast, and the blood vessel condition and the location of the lesion are not clear. Use a thin tube to be safe, and do not use a tube that is too thick for the injection of contrast agent.
Now, with angiography, the blood vessels are clearly visible on the monitor.
Although this X-ray imaging is not as powerful as Zhou Shengsheng's auxiliary system.
But it can be regarded as a plug-in developed by today's medical technology.
Therefore, PCI surgery must be performed in an X-ray machine environment.
Of course, Zhou Shengsheng has an auxiliary system. He can accurately know the location and condition of the diseased blood vessels without using an X-ray machine or angiography.
But he is not alone in the surgery, and the process still has to go through.
Next, Zhou Shengsheng hardly 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 guiding catheter to pass through Boss Li's blood vessels.
Wait until you reach the diseased blood vessel.
PCI surgery is almost half successful.
The next step is to insert the stent through the guiding catheter.
The entire operation was very easy for Zhou Sheng to perform.
In this minimally invasive surgery, Zhou Yisheng’s powerful auxiliary system plays an even more vivid role.
If it weren't for the presence of Bai Mingming and others.
He can do these operations without even looking at an X-ray machine.
An hour later.
A metal mesh stent was left in Boss Li's blood vessel.
Zhou Sheng carefully removed the catheter again.
The next step is to remove the "door" left on Boss Li's right arm.
This job is not very difficult.
There is no life risk.
In minimally invasive surgery, the wound is very small and no stitches are needed. It is just a wound treatment.
Zhou Sheng asked Bai Mingming to do the work for him.
Bai Mingming came here mainly to learn the PCI puncture technique from Zhou Sheng.
After watching it for a long time, he had gained a lot.
At this time, he became generous and gave up the job of "breaking down the door" to Su Quan and Cao Xin.
These two are still in the internship period, so of course they are willing to do any kind of work.
This surgery will make the most idle person understand.
Su Quan and Cao Xin were busy "breaking down the door".
Zhou Sheng chatted with Boss Li again.
In fact, Boss Li was conscious throughout the entire operation.
It's just putting a guide wire or catheter in a blood vessel, which is a delicate job. Zhou Yisheng didn't have time to chat with him.
At this time, of course it is possible.
"How's it going? You're not feeling uncomfortable," Zhou Sheng asked.
"It's okay. Is the operation completed?" Boss Li asked.
"The stent has been installed successfully. Your wound is being treated."
Boss Li was slightly surprised, "So fast?"
Zhou Sheng smiled and said, "One hour, normal operation."
Boss Li thought to himself that it seemed that his decision was correct. This young doctor could complete the PCI operation in one hour, which proved that he was quite capable.
Boss Li said: "Thank you very much. By the way, I don't know what to call you?"
Zhou Sheng said: "My name is Zhou Sheng, and I am the one I want in my life."
