Chapter 535 Imported blood vessel supply crisis

After the female reporter left, the cardiac surgery department quickly returned to calm.

At 3 o'clock in the afternoon, 6 hours after the operation, the patient finally woke up from anesthesia in the extracardiac ICU ward.

The doctors who heard the news surrounded the patient and carefully examined her physical condition.

"The patient's blood supply has recovered well. The skin temperature is 36.7, the pulse is 78, the heart rate, and the blood pressure have all returned to normal."

Yunfeng completed the physical examination of the patient and compared it with the parameters on the monitor one by one. After confirming that they were correct, a smile appeared on his face.

Since he had already been busy for a day when the operation started and fell down from exhaustion, he did not participate.

Now that I see the success of the operation, I can't help but feel a little regretful. It would be great if I could do such a major operation with the director.

However, he did not show any emotion and gave the doctor's orders like a precise machine.

"The patient will then be monitored closely to prevent signs of bleeding and infection, as well as any neurological complications and liver and kidney damage."

"The patient is young and in good physical condition. He should be able to recover quickly. He is expected to be extubated tomorrow and the day after tomorrow. As long as he survives the first three days without any problems, he can be sent to a general ward for rehabilitation treatment."

The doctor next to him couldn't help but exclaimed: "It's amazing. After a meter-long blood vessel was replaced, the patient's condition recovered so well."

Yunfeng said with a smile: "The director's aortic replacement surgery is the signature of our department. Three months ago, a patient had a 40-centimeter artificial blood vessel. He recovered well after the operation and was extubated the next day.

I was discharged from the hospital in less than ten days."

"The imported polyester blood vessels from McVei were used that time. Wasn't the effect very good? Why did the 1-meter length be replaced with Sanqing's new product this time?" A young resident doctor asked in confusion.

road.

Yunfeng glanced at the patient and found that the patient had fallen asleep, so he replied in a low voice: "Isn't it that imported artificial blood vessels are too expensive? One tube costs 20,000 to 30,000 yuan, and a 1-meter-long blood vessel replacement surgery must be used at least.

Three tubes, which is almost 100,000, plus the surgery fee and ICU hospitalization fee, the financial burden on the patient is too heavy."

"Because Sanqing's artificial blood vessels are still in clinical trials, they are all free, including surgical fees and hospitalization fees. If you don't have money to treat patients, which one will you choose?"

The resident doctor scratched his forehead in embarrassment: "Of course I choose the free one, I understand."

Yunfeng smiled slightly and explained: "Besides, Sanqing's artificial blood vessels are no worse than MaiKeWei's. MaiKeWei's blood vessels are polyester polyester, but the surface is impregnated with a natural silk fibroin coating, which improves the maneuverability and

It is biocompatible and the patient’s rejection reaction is lighter than that of ordinary polyester blood vessels.”

"But Sanqing's artificial blood vessels are all made of biological elastin materials. There are basically no polymers in them. The technical content of the materials is naturally different, and the biocompatibility is even worse."

"Not only has the patient's rejection reaction been greatly reduced, but the stability and tensile strength are also very high. Most importantly, it also has a certain degree of growth."

"I read the animal experimental data on artificial blood vessels. Sanqing's bioprotein artificial blood vessel implant can perfectly replace the original aorta and integrate perfectly with the native blood vessels at both ends 14 days after implantation."

"Before this total aortic replacement surgery, we also performed two replacement surgeries of about 20 centimeters last week, both of which used Sanqing's artificial blood vessels. The surgical results were very good. Not only was the implantation process easy to operate, but it was not easy to penetrate.

The elasticity of the blood and material is also very high, and it can still maintain high stability after the stent is placed."

Another doctor suddenly interjected: "You don't have to be superstitious about imported artificial blood vessels. That Mai Kewei, I heard that there was a recall incident a few years ago. It is said that the anastomosis of the branches of the artificial blood vessels leaked during the operation, and then it was

I complained, but within two years, the product was recalled again due to packaging issues.”

"In my opinion, imported products are increasingly being overshadowed by domestic products. If we can use domestic products, we will use domestic products. At least Sanqing has not had any recalls in the world so far."

Yunfeng nodded in agreement and said: "I agree with you, but it's not because of product quality, but because of supply issues. You may not know that the recent relocation of Mai Kewei's factory has caused a sharp drop in supply, and imported artificial blood vessels are now basically unavailable.

Demand exceeds supply."

"Currently there are only two manufacturers of artificial blood vessels, namely Terumo of Sakura Country and McVei of Europa. The latter, in particular, occupies more than 70% of the market."

"In the past, only a few hospitals could perform artificial blood vessel replacement. Now more and more hospitals can do it, but the production of artificial blood vessels has not caught up, so it has become increasingly scarce."

"In addition, there was a problem with the relocation of Mai Kewei's factory. The old factory was closed, but the new factory has been unable to start operations. Now, imported artificial blood vessels are still in stock except for the tertiary hospitals in Beijing and Haicheng, and hospitals in other regions are out of stock.

Already."

"The domestic demand for artificial blood vessels has always been huge, with 20,000 to 30,000 artificial blood vessels needed every year, accounting for 10% of global consumption."

"If you think about it carefully, if there is a problem with the supply of foreign manufacturers, the first guarantee must be their domestic market supply. As for whether we are out of stock, or whether the patients are in danger, waiting for artificial blood vessels to save their lives, they don't care.

.”

"That's why we have to support domestic artificial blood vessels. This is a matter of principle. Otherwise, we will always be controlled by others and choked by foreign manufacturers."

"This is not just a quality issue, but a matter of life and death. Even if domestic artificial blood vessels are not as good as imported ones, we still have to use them, let alone Sanqing's artificial blood vessels that are inferior to imported ones, so we have no reason not to use them."

The doctors around him were silent for a long time and nodded.

"That's the reason. When it comes to the patient's life or death, you still have to hold it in your own hands."

"I can't even think about it. What if I need an aortic replacement surgery and need an artificial blood vessel, but there is no stock at all?"

"That's right, when have domestically produced products ever been out of stock? Only imported products are out of stock all day long, either because of strikes or relocations, for various reasons. Even if the factory has a power outage, they will be out of stock. This is frustrating.

No."

"That's right, since the production capacity is not enough, don't let them spoil it. We can produce it ourselves and we can have as much as we want."

Seeing that everyone was getting excited, Yunfeng quickly waved his hand and said: "As long as everyone understands, let's go, let's go see the next patient."

Guangdong Province, Yangcheng Zhongshan Hospital.

In the dark night, Dr. Cao, who was on duty in the emergency department, was extremely busy.

Suddenly, a rapid siren sounded, and a 120 ambulance rushed into the hospital.

Dr. Cao heard the familiar and harsh voice, looked at the long queue of waiting patients, and suddenly became desperate: "Again?"

Soon, a 40-year-old male patient was lying on a trolley and was pushed in by a nurse.

"The patient had a fishbone stuck in his esophagus while eating. He suddenly had difficulty breathing and suffered chest pain. So he quickly called 120 and was sent to the hospital."

Dr. Cao became a little uneasy when he heard this: "The fishbone punctured the esophagus wouldn't be so serious. It couldn't be that it penetrated and entered the trachea."

He immediately checked the patient's esophagus. After checking for a long time, he could not find any trace of fish bones.

"I suspect the fish bone has penetrated the trachea. Let's take a film."

After issuing the examination order, Dr. Cao lowered his head and continued to serve other emergency patients as he watched the patient being pushed into the night CT room.

Not long after, family members came over with the CT examination results.

When Dr. Cao took the film and looked at it, he couldn't help but take a deep breath.

On the CT film, a white fish bone more than 2 centimeters long was clearly displayed, but it did not appear at the tracheal position where he predicted.

Instead, it pierces the patient's aortic arch like a sharp arrow.

Thinking that with the slightest movement of the patient, the fish bone would pierce the thoracic aorta at any time, like a fish swimming into the sea, leaving a ruptured gap where blood would spurt out, Dr. Cao's forehead instantly became beaded with beads of sweat.

"Go through the hospitalization procedures first. I have already notified the experts to come for consultation."

He warned his family members, then stood up in a flash, picked up the phone at the speed of light, and called the doctors on duty at the Department of Gastroenterology and Cardiac Surgery.

When the patient was admitted to the ward, the doctors from the gastroenterology department and cardiac surgery department all gasped after looking at the CT images.

The fish bone had penetrated the esophagus, breached the mediastinum, and pierced the thoracic aorta near the sixth thoracic vertebra, causing two fatal injuries in the patient's body.

First, it penetrates the esophagus, and the risk of fatal infection increases exponentially.

Then it penetrates the aorta and forms a false aortic aneurysm. Once the aneurysm ruptures, the huge arterial pressure will cause the patient to quickly die from massive hemorrhage.

The thoracic aorta is the largest arterial blood vessel in the human body. The pressure in the blood vessel is very high. Once a breach occurs, the bleeding will be like a spurt, just like a dam bursting, making it difficult to rescue.

"According to the experience and data of colleagues at home and abroad, there were a total of 23 similar cases of patients with similar situations, 20 died, and only 3 were saved, which can be called a narrow escape."

The cardiac surgeon said with a serious face: "I can't handle such an operation. I have to wait for the director to come and perform the operation."

The gastroenterologist also shook his head and said: "The hospital in Haishi has shared a successful example. The operation needs to be carried out in stages. In the first stage, an esophageal fistula is performed, and at the same time, the thoracic aorta is removed and replaced, and in the second stage, an esophageal reconstruction surgery is performed.

Not only is the cost high, the patient will also lose his esophagus and his quality of life will be greatly affected."

An hour later, the directors of the cardiology and gastroenterology departments arrived one after another for a joint consultation.

Should surgery be performed directly? Or should interventional surgery be combined with endoscopy?

Time passed by, and after many discussions, the experts finally made a decision and chose to perform surgery to save the patient.

At this moment, the nurse suddenly rushed in.

"It's not good. The patient suddenly vomited blood, accompanied by hemorrhagic shock."

The director of the gastroenterology department looked at everyone, stood up and said: "Time is running out, we must do the operation immediately. I will go to the family to discuss it immediately, hoping to gain their support."

"Wait a minute, if you want to have surgery, there is still a big problem." The director of cardiology frowned and said.

"The patient's thoracic aorta had fish bones and hemangioma formed. No matter what, it had to be replaced with an artificial blood vessel."

"But," he spread his hands and said helplessly: "Now all the tertiary hospitals in Yangcheng have no inventory of artificial blood vessels. We must find supplies from Beijing and Haishi."

"Oh, there is such a thing?" The director of the gastroenterology department showed an expression of disbelief for a moment: "Don't you use a lot of artificial blood vessels? Are they still out of stock? Why don't you stock more?"

The cardiac director coughed lightly and explained: "Imported artificial blood vessels are purchased through agents, and now the agents have no surplus."
