This doctor is very stable

Chapter 663 Intercepting the Great Saphenous Vein [For subscription, ask for a monthly pass. 】

The mouth is cleaned, intubated, administered, and the anesthetic is confirmed to enter the patient's lungs.

Liu Meng did it very carefully.

There were two big bosses present.

If you do it rough, you will lose your job!
Although hospitals have always been short of anesthesiologists, they have always been short of good doctors.

This point is clear to every doctor, whether it is a surgeon or an anesthesiologist.

After giving the medicine, Liu Meng withdrew, and the patient soon fell into a coma.

Lin Ran looked at the equipment nurse beside him and said, "Tweezers, alcohol cotton, iodophor."

After receiving the tweezers, the operation officially began.

Lin Ran first disinfected the patient's left chest, but the patient's left calf.

The length of the patient's left coronary artery atherosclerosis reached seven centimeters.

The right coronary artery has a sclerotic stenosis of six centimeters.

Heart bypass surgery, also known as coronary artery graft surgery.

It is to intercept a section of vein from the patient's body and implant it into the patient's body to replace the coronary artery that has hardened and embolized.

And this vein generally chooses the great saphenous vein.

The great saphenous vein is the main superficial vein of the human calf.

It starts from the medial side of the dorsal venous arch of the foot, passes through the front of the medial malleolus, goes up along the medial side of the calf with the saphenous nerve, passes about two centimeters behind the medial femoral condyle, enters the inside of the thigh, and accompanies the medial femoral cutaneous nerve.

Gradually, it passes through the saphenous vein hiatus and joins the femoral vein on the outside and below the pubic tubercle.

Therefore, before thoracotomy, it is necessary to intercept the great saphenous vein first!
The reason for choosing the great saphenous vein is, of course, because the interception of the great saphenous vein will not cause too much impact on the patient's body.

Of course, the easier interception of the great saphenous vein is also an important factor!
There are two ways to intercept the great saphenous vein, one is to cut and intercept directly.

The other is minimally invasive interception.

In clinic, the chief surgeon often chooses to cut and intercept.

Because the minimally invasive interception may injure the hidden nerve, and in severe cases, it may cause paralysis of the patient after the operation is completed.

Compared with minimally invasive interception, incision and interception of the great saphenous vein also require ligation, hemostasis, and easy suturing.

Although the recovery speed of the operation is slightly slower, it is safe and reliable.

After the disinfection was completed, the nurse quickly spread the surgical towel on the patient's body.

The patient's great saphenous vein is just under the skin, so there is no need to determine the position and draw a positioning line!
Of course, Lin Ran carefully designed these obvious problems in the operation plan.

However, when cutting, it is quite a test of the operating level of the surgeon.

After all, blood vessels aren't straight.

At the same time, the blood vessels are closely connected with those hidden under the skin.

Therefore, cutting and intercepting is also a test of the knife skills of the main knife.

Received the scalpel from the instrument nurse.

The knife is started at the upper end of the patient's ankle, and the incision is started along the left end of the blood vessel.

Push down and up.

Li Yulong watched Lin Ran's incision, and nodded very satisfied.

The interception and incision of the great saphenous vein is a test of knife skills.

The incision must be made along the edge of the great saphenous vein, and the incision should not be too deep, otherwise it will easily cause unnecessary hidden nerve damage. Also, it should not be cut too far, otherwise it will not be conducive to the interception of blood vessels, let alone incision The great saphenous vein, otherwise it has not been transplanted, and the great saphenous vein that replaces the patient is damaged, which is definitely not suitable.

The thirteen centimeter incision was equivalent to the skin of the patient's calf being cut open by Lin Ran.

After the incision is completed, it is natural to carry out blood vessel occlusion!
"Blocker, Fine Shear."

Block the proximal end of the great saphenous vein, cut off, ligate...

Lin Ran used tweezers and fine scissors to slowly free the great saphenous vein.

"It's so powerful, such a steady free technique."

Amidst Zhang Yang's admiration, a great saphenous vein with [-] to [-] cm long hair had been successfully freed by Lin Ran.

Similarly, the young cardiothoracic doctors watching the live broadcast of the operation in the conference room couldn't believe their eyes.

Lin Ran's method of intercepting the great saphenous vein was too steady, it looked a little slow, but in fact it was already very fast in terms of overall speed.

It took Lin Ran less than 10 minutes to intercept the great saphenous vein.

10 minutes is not even enough time to suture and bandage a wound!
At this time, the great saphenous vein will be intercepted and implanted in the incubator prepared by the nurse in advance.

Before the patient's chest cavity is opened, and before the patient's atherosclerotic crown is intercepted.

The great saphenous vein that will be implanted in the patient's body to replace the coronary arteries naturally cannot be exposed to the air and let it die, otherwise, even if the operation is completed, the great saphenous vein will not survive.

"Saline."

The next job is naturally to rinse and disinfect the patient's cut leg, then ligate the remnant great saphenous vein, and suture the incision.

Lin Ran didn't hesitate to accept the bottle of normal saline from the equipment nurse.

The entire bottle was poured on the patient's calf incision, "tweezers, alcohol cotton."

After simple cleaning, it is ligated and sutured.

Lin Ran has some master-level three-item sutures, so such a simple incision suture is naturally no problem!
"Amazing, this stitching speed is really fast!"

At this time, Zhang Yang seemed like a little doctor who had never seen the world.

"Doctor Lin, you are amazing!"

There was also a wave of admiration from fans in the conference room.

"No wonder our dean is so relieved that Lin Ran will perform this heart bypass operation."

"Excellent technology!"

……

After dealing with the patient's cut leg, Lin Ran turned his attention to the patient's left chest cavity.

"Tweezers, alcohol cotton, iodophor."

Without thinking, Lin Ran stretched out his hand and said.

Before the operation, a very precise operation plan was made, and Lin Ran's operation thinking was particularly clear at this time.

This is the advantage of doing a good enough surgical plan.

During the operation, just follow the idea of ​​the operation plan.

Disinfect before the operation, draw the positioning line, the nurse spreads the drape, and cuts the operation port.

Lin Ran pushed forward the operation process in an orderly manner.

The bosses on the side are better and more comfortable!

The pace of Lin Ran's operation was very smooth.

It's extremely pleasing to watch.

Just like watching the birth process of a piece of art, it starts from scratch and gradually advances.

The Chief Physician of Cardiothoracic Surgery, Liang Yongsheng, was standing next to Big Brother Chen, and he looked at Big Brother Chen and said enviously.

"Principal, I really envy you for receiving a student like Lin Ran. This surgery even makes me feel ashamed!"

The boss Chen chuckled. From the operation Lin Ran had just performed, he saw Lin Ran's progress again, and the progress was not small.

This made him a little puzzled!
This little guy is really amazing.

If he can really complete the heart bypass operation, then maybe Lin Ran can also complete the liver transplant operation.

Maybe my previous care was really wrong.

Big brother Chen's thoughts were racing.

Looking at Lin Ran's operation, Boss Gu also had the urge to grab Lin Ran out of his liver and lock him up to prevent him from going out.
