This doctor is very stable

Chapter 664 Establishing extracorporeal circulation [For subscription, ask for a monthly ticket. 】

Without him, the wealth will not be exposed, and the treasure will not be shown to others!

Besides, Li Yulong coveted Lin Ran, which was Sima Zhao's heart, and everyone knew it.

After the preoperative disinfection was completed, Lin Ran quickly drew the positioning line.

More than ten centimeters long, the incision is not too long.

The patient himself has three highs and his body immunity is weak, if it is not necessary for surgery.

Lin Ran would not choose to perform large incision surgery on patients with three highs.

Because of the postoperative healing, the patient may not be able to survive.

But there is no way, the degree of coronary atherosclerosis of the patient determines whether the patient needs surgery, and the patient's coronary atherosclerosis is relatively long and both left and right.

The length of the sclerosis and stenosis of the coronary arteries also determines the size of the incision!
The left intercostal entrance.

It was consistent with what Lin Ran mentioned in the previous operation plan.

After confirming the incision approach, Lin Ran no longer hesitated, "Scalpel."

He took the scalpel, held it in a bow, and lowered the knife.

The extremely sharp blade touched the patient's skin and immediately broke a hole.

Slashing deeply, Lin Ran could feel the feeling of the blade cutting through different tissues.

Skin, fat layer, muscle layer, fascia layer, pleural layer!

The blade cut across the wall of the intercostal cavity, followed by blood.

During heart bypass surgery, blood loss is inevitable.

The little nurse on the side has already hung a blood bag on the patient and is on standby at any time.

Lin Ran prepared [-] milliliters of blood in the operation plan.

Soon, under Lin Ran's crisp and sharp knife technique, an incision more than ten centimeters long appeared on the patient's side intercostal space.

Li Jinxia held an electrocoagulation pen in his hand, even though he was already a seasoned attending doctor.

But she was still a little nervous about this operation. Except for the chief surgeon, Lin Ran, all the doctors present were chief physicians, and even the anesthetist was a chief physician, not to mention the big brothers Chen and Li Yulong.

All at the professor level!

As long as she knows that the little attending doctor has to go on stage to pull hooks, how can this make her not nervous.

"呲呲..."

There was the sound of the electrocoagulation pen touching flesh, and at the same time bursts of white smoke came out.

A smell of burnt meat followed.

"Hold on."

Li Yulong looked at his niece and said a word of relief.

"Ah."

Li Jinxia responded, but still didn't dare to slow down.

For thoracotomy for patients with three highs, if there is a delay of 1 minute, the patient will be more dangerous.

This is very clear in her heart.

Otherwise, Lin Ran wouldn't have to make such a strict surgery plan for himself.

When Li Jinxia stopped the bleeding on the chest wall, Lin Ran was also staring at the patient's life monitor.

I'm afraid that the patient's heart rate and breathing will go wrong in the next second.

In Lin Ran's surgery plan, the part of surgical rescue was also formulated.

If the patient's chest is opened, the heart rate is abnormal, the breathing is disordered... and other emergency measures!

Soon Li Jinxia completed electrocoagulation of the chest wall to stop bleeding.

"Tractor."

Li Jinxia took over the retractor steadily from the equipment nurse's operation, and hooked the patient's cavity wall with two of his first hands, and stretched the ribs on both sides!

The operation port was expanded, and the mediastinum in the patient's chest with the heart in his heart was clearly visible.

Likewise, various venous and arterial vessels are also clearly visible.

Anterior descending branch, posterior descending branch, circumflex branch, left ventricular branch, conus branch...

It looks like the various integrated circuits in a computer.

Of course, the distribution of blood vessels in the human body is far more beautiful than integrated circuits.

Because human blood vessels are naturally formed, they evolved through tens of thousands of years of human evolution.

How can an artificial object like an integrated circuit be comparable!
"Tweezers, a scalpel."

The source of the atheromatous coronary is attached to the pericardium, so the operation also starts from the heart.

"Tweezers, non-injury forceps."

Li Yulong and Zhang Yang also started to cooperate with Lin Ran in the operation.

Once the patient's chest cavity is opened, it is a race against death!
This patient in particular, especially with heart bypass surgery.

Half a slack is not advisable!

……

Outside the operating room, the patient's family members have been staring at the warning light on the operating room.

Time passed by little by little, and their family had never felt that time could pass so long.

During the three or four hour operation, ordinary people take naps and naps.

But now the family feels like their days are like years!
……

In the conference room, there was no sound at this time.

The young doctors in the meeting room were all staring at the live screen.

It seemed that speaking would disturb Lin Ran's operation!
Not even breathing.

For fear of disturbing those who are undergoing surgery.

……

In the operating room, Lin Ran carefully opened the thoracic mediastinum with a scalpel.

After pulling the hook, a beating heart appeared in the eyes of everyone under the shadowless lamp.

Looking at the patient's heart, everyone in the operating room began to look serious.

Various blood vessels are also attached to the yellowish pericardium.

Aorta, main vein, right coronary artery, left coronary artery...

Veins are dark red in color and arteries are bright red in color.

However, after the thoracic mediastinum was opened, everyone could clearly see the abnormalities of the right coronary artery and the left coronary artery.

Porridge is off-white!

After seeing the condition of the patient's coronary arteries clearly, Lin Ran smiled, "The situation is within the predicted range!"

Before the operation, in the operation plan, it is necessary to check the length of coronary artery atherosclerosis.

It's about the success or failure of the surgery!

Fortunately, the patient's coronary artery and Lin Ran had the same judgment.

Without any hesitation, Lin Ran put the scalpel in his hand on the tray in front of the equipment nurse.

"Prepare extracorporeal circulation equipment, prepare heart insulation, blockers, tweezers, and scissors."

In order to complete the bypass of coronary artery, it is natural to cut off the coronary artery.

After the coronary artery is blocked and cut off, other organs and tissues of the patient cannot get blood supply, such as the liver, spleen and stomach, etc...especially the brain.

Even if the blood oxygen supply of the heart is lost for a short time, the brain will be necrotic and even die.

So this is the importance of establishing extracorporeal blood circulation, using artificial extracorporeal circulation to temporarily replace the engine of the heart to supply blood to other organs and other parts of the human body.

After a while, the little nurse who had been prepared for a long time said, "The artificial extracorporeal circulation is ready!"

Lin Ran has sharp eyesight and quick hands, blocking the right coronary artery!Block the left coronary artery.

Without stopping, Lin Ran took the scissors from the equipment nurse and immediately cut off the two-day coronary artery.

The coronary artery was cut off, and the patient's blood pressure was dropping rapidly on the patient's life monitor.

"Link extracorporeal circulation!"

The nurse took a picture of the connection port of extracorporeal circulation to Lin Ran.

Connect the right coronary artery, connect the left coronary artery...

"Extracorporeal circulation was established successfully."

"The patient's blood pressure started to rise."

……

After completing the extracorporeal circulation, Lin Ran and everyone in the operating room breathed a sigh of relief.

The establishment of extracorporeal circulation is also one of the difficulties in this operation.
