Start with an emergency physician

See all

Yuan subconsciously glanced at the end of the corridor, turned the operating bed, and pushed it to the operating room with his back to the end of the corridor.

Qian Wei's wife heard the noise, waited for another two seconds, and slowly raised the camera of her mobile phone that was recording...

It was not until a minute later that Qian Wei's wife came out and entered Qian Wei's ward, silently folded the quilt, and tidied the things on the bed.

At this time, Qian Wei's wife could not do anything to help Qian Wei. Even the most basic companionship could become a risk factor that would kill Qian Wei. She could only hide behind and give silently.

After cleaning the bed, Qian Wei's wife sat on the bed, turned on the video on her mobile phone, wiped her tears, and browsed the seven years since they knew each other, until today, Qian Wei was pushed into the operating room by several doctors.……

……

In the operating room, the light from the shadowless lamp was so dazzling that Qian Wei could hardly open his eyes.

"Did you know that the former president of Country M also had a heart bypass surgery?"Zhou Yuan glanced at Qian Wei and found that he was a little nervous, so he found a topic to talk about.

"He did it too?" Qian Wei looked at Zhou Yuan in surprise.

Zhou Yuan nodded,"Yes, as you know, people in Country M like to eat junk food like fried chicken and hamburgers, so many of them have high blood pressure and high blood lipids, which are one of the causes of acute myocardial infarction, so the heart is naturally prone to problems."

"Is the coronary bypass technology in Country M better than ours?" Qian Wei asked.

Zhou Yuan frowned and said,"It's not better than ours. They have an innate advantage in technology, and some of their equipment may be better than ours, but they have fewer people, fewer patients, and their doctors don't have enough experience."

"On the contrary, in our country, many doctors may perform four or five operations a day. In terms of surgical skills, I am confident that doctors in our country are better.

Qian Wei smiled and said,"That's great.""

"The equipment has been tested and is ready." The nurse said.

Zhou Yuan nodded and said to Qian Wei,"Lie down in a comfortable position. We will anesthetize you soon. When you wake up, your heart problem will be solved."

Qian Wei felt much more relaxed, nodded, and lay down on his back.

"General anesthesia, endotracheal intubation to maintain breathing."Zhou Yuan said.

The anesthesiologist and He Jianyi came up, one in charge of anesthesia and the other in charge of intubation.

"Should we do internal thoracic artery bypass or radial artery bypass?"The director of cardiac surgery asked.

After choosing arterial bypass, which artery should we choose next?

""Radial artery bypass." Zhou Yuan said.

The long-term patency rate after internal thoracic artery bypass surgery is good, with a 10-year patency rate of 90%. The internal thoracic artery can regulate blood flow according to the physiological needs of myocardial blood supply, and the chance of atherosclerosis is very small, but the length of the internal thoracic artery is limited and not suitable for Qian Wei.

Although the patency rate of radial artery bypass surgery is not as good as that of internal thoracic artery surgery, there is no need to worry too much about the length.

Generally, doctors will perform internal thoracic artery bypass surgery because of the patency rate.

However, with Zhou Yuan's technology, the disadvantage of insufficient patency of radial artery can be overcome, and radial artery bypass surgery is obviously more suitable.

"Anesthesia is complete." The anesthesiologist's voice sounded.

Zhou Yuan immediately raised his head and checked the time."The operation begins."

"Disinfection."

Zhou Yuan and He Jianyi began to disinfect the skin of the chest and upper limbs.

The chest was for opening the heart, and the upper limbs were for taking the radial artery as a vascular bridge.

The great saphenous vein, radial artery, internal thoracic artery, etc. can be used as vascular bridges and transplanted to other parts of the body because the tissues and organs they connect have compensatory blood vessels.

For example, the radial artery, the deep palmar arch and the superficial palmar arch in the palm can replace the radial artery and provide compensatory blood supply to the radial side of the hand, thereby ensuring that the blood supply will not be affected in the absence of the radial artery.

Although it will definitely have a certain impact on the patient's body, such as not being able to engage in strenuous exercise, not putting too much burden on the palm, etc., but compared to saving his life, this is nothing.

""Start the radial artery graft removal." Zhou Yuan said.

The cardiac surgeon next to him handed over a scalpel and stared at Zhou Yuan's movements closely.

Zhou Yuan picked up the scalpel and made a few gorgeous cuts to expose the radial artery.

The radial artery is actually the artery at the wrist, which is the part where the pulse is felt clinically.

When Qian Wei recovers and is discharged from the hospital, he will go to see a Chinese doctor again. If he is found to have no pulse, will the old Chinese doctor be scared to death?

Zhou Yuan almost laughed out loud.

"Zhou Yuan, your vascular clamp……"He Jianyi looked at Zhou Yuan in horror.

Who would smile while operating? It was too scary...

The cardiac surgeon came over and asked,"Old He, how long has it been since Zhou Yuan touched a scalpel?"

He Jianyi was silent for a moment and said,"It's been several days since I last used a scalpel.……"

Zhou Yuan focused on the operation and ignored He Jianyi and the director of cardiac surgery.

After deftly blocking the blood flow of the radial artery, Zhou Yuan began to measure the pulsation at the distal end of the palm.

Theoretically, after the loss of the radial artery, the body can compensate for the blood supply through the deep palmar arch and the superficial palmar arch, but it is also necessary to prevent the deep palmar arch and the superficial palmar arch from having accidents and special situations where the compensatory blood supply disappears.

"The distal pulsation is good, the thumb artery oxygen saturation has not decreased significantly, and the compensatory blood supply is good."

This data shows that the radial artery can be harvested.

Although Qian Wei's coronary artery is stenotic to 80%, there is no stenosis of multiple blood vessels, so only one hand is needed, that is, unilateral radial artery harvesting. Unilateral radial artery harvesting is generally performed with the non-dominant hand. Qian Wei is right-handed and uses his right hand more, so Zhou Yuan chose the left hand, which is relatively less used.

"The upper limb is abducted at a right angle and rotated backward."Zhou Yuan said.

He Jianyi posed Qian Wei.

After disinfecting and laying the towel, Zhou Yuan picked up the scalpel again and began to dissect along the direction of the radial artery two centimeters below the elbow.

During the dissection, Zhou Yuan's knife was biased towards the inside of the arm to prevent injury to the blood vessels on the outside.

After the incision was completed, Zhou Yuan made another skin incision at the distal end, reaching two centimeters above the wrist.

After the skin was incised, Zhou Yuan began to separate the subcutaneous fat.

The blood vessels are protected by adipose tissue, superficial fascia, deep fascia, etc., and these things must be separated from the outside to the inside in order to reveal the blood vessels.

After the subcutaneous fat was separated, the brachioradialis muscle was exposed in the surgical field.

The brachioradialis muscle is a muscle on the forearm, and its proximal two-thirds of the area covers the superficial layer of the artery.

Next to the brachioradialis muscle, it is connected to the radial flexor carpi.

Zhou Yuan dropped the knife again, cut the belly of the two muscles, and exposed the deep fascia between the belly._To read the ununderlined version of the novel, please download Fulu Novel AP
