Chapter 736 The spirit of the meeting (Add 68 for leader Tobia A04)

PET scanning is a very expensive device. The price of a single machine of the most traditional PET-CT is about 3000 million.As for large-scale equipment, in order to prevent local hospitals from rushing to purchase machines and causing waste, the relevant departments have adopted the method of "setting plans and restricting audit purchases" for this level of equipment.If a local hospital wants to have its own PET scanner, it must first apply to the higher-level department through fixed channels, and only after it is determined that the amount does not exceed the amount in the five-year plan can it purchase it after approval.

When PET scanning technology first emerged, a single PET was planned and managed as a Class A medical device of the same level as the proton therapy tumor system.After more than ten years of development, more than 710 ordinary X-ray positron emission tomography scanners, that is, PET-CT, have been equipped nationwide.And it was moved down to be a Class B management.At present, what is still planned in Category A is the PET/MR (Positron Emission Magnetic Resonance Imaging System), which is equipped with only 33 sets in the country.

Compared with other imaging examination methods, the biggest feature of PET scan is that it can directly show the operation of various organs.After injecting radioactive 18F-FLT and other contrast agents, PET-CT scanning can quickly find abnormal tumor tissues that absorb a large amount of thymine.

This also makes PET scanning technology an absolute weapon for human tumor screening.The extremely high sensitivity and less damage than biopsy make it the core inspection content of high-end medical examinations.

Unlike the traditional rapid CT scan, since the contrast agent needs to be injected into the patient and it takes a while for the contrast agent to enter the tissue, PET scanning is a waste for a large emergency center like the Fourth Hospital.Cancer patients generally do not have emergencies, and most of them only have severe illnesses.

That's why Sun Li'en asked this question - after all, the current production of PET-CT and PET/MR is mainly monopolized by GE, Philips and Siemens.Japanese companies do not have related manufacturers, and the content donated by Takeda Pharmaceuticals probably will not include this.

"We can't do it in our hospital." Zhou Ce spread his hands, "If we want to do it, only the affiliated hospital in Ningyuan can do it. I remember that Ningyuan Medical College has an experimental PET/MR, but that thing... Anyway, it’s okay to put a mouse or something in it, but let’s put a beagle in it. Humans definitely won’t be able to use it.”

The First Affiliated Hospital of Ningyuan Medical College is the most capable comprehensive tertiary hospital in Ningyuan City.It is not surprising that they have equipment.Sun Li'en nodded, and after making a note in his notebook, he shifted the focus back to the inspections that the Fourth Hospital can do now.

"From a supernatural point of view, it is unrealistic to directly make a fistula for the drainage tube. At least there is no suitable space for other parts of the access." Xu Yourong timely mentioned the difficulties faced by neurosurgery on this issue. "Drainage tubes are generally ready-made integral devices, and it is difficult to make a hole for drainage. And even if a hole can be made, there is no place on the channel from the outside of the skull to the abdomen that is suitable for the drainage of a fistula—unless You do the fistula from the intracranial reservoir or from the intraperitoneal diversion."

Lateral ventricular drainage is a secondary operation that is not too difficult.But its core component is the key—the lateral ventricle drainage tube is a relatively sophisticated system.With this system, physicians are able to actively select the intracranial pressure at which drainage begins by selecting the valve and reservoir.

The fluid storage bag is generally located in the neck close to the body surface. Its main purpose is to check the working condition of the entire drainage system by pressing, and at the same time, it can also adjust part of the shunt pressure.

But the reservoir does not have a puncture function.In other words, traditional fluid storage bladders do not have this function.In order to facilitate the crossing of the brain-blood barrier, and also to facilitate the extraction of CSF for laboratory examination, some companies have introduced reservoirs with silicone domes instead of ordinary plastic shells.This newly designed fluid storage bag can withstand repeated small-angle punctures by fine needles, and can even be used as a channel for painless intrathecal injections directly through the cerebrospinal fluid barrier.

The problem is... this silicone dome reservoir is not the mainstream or standard design of the lateral ventricle drainage reservoir.To use such a reservoir, it is necessary to use the silicone dome component at the time of implantation.

"This..." Sun Li'en was a little embarrassed when he heard this, "Can you change the fluid storage bag?"

"It's not safe enough. It may affect the original drainage." Xu Yourong is very cautious about this proposal, "We don't have the original drainage plan here, and it is risky to replace the fluid reservoir rashly. I think it can be considered An injection port that can withstand repeated punctures is added at this location in the peritoneum."

The nature of the injection port is similar to that of the silicone dome reservoir, but it is used more frequently in the fourth hospital. As a mainstream development direction of deep vein injection of chemotherapy drugs, the injection port itself is not too expensive, and the technology is relatively Mature.

"Then I have to invite a general practitioner to come for a consultation." After Sun Lien made a note, he looked around and seemed to have nothing else to add, so he decided to adjourn the meeting, "Let's go, let's wake Yuan Pingan up."

When Dr. Yuan Ping'an woke up on his camp bed, the clock in the office had already pointed to the position of [-]:[-].

He didn't set his alarm clock when he fell asleep in his camp bed at four o'clock this morning.Yuan Ping'an was very sure that when his colleagues came to work in the morning, that voice would definitely be enough to wake him up.But what he didn't expect was that it was already [-]:[-], and the whole office was empty——except for himself, there was no one else.

It feels a bit like coming to the class early in the morning and waiting for the class, only to find out that there is no one else but myself after waiting.Yuan Pingan even wondered for a few seconds whether he was still dreaming—the work arrangement of the diagnostic center was still different from that of the school.At least there should not be such a situation where "only I have made a mistake, but the whole school is actually on holiday today".

Yuan Pingan sat up from the bed, packed his camp bed, and poured himself two cups of black coffee.Then he looked out the window to see the situation—fortunately, the Fourth Hospital has not been closed by the whole hospital, and there are already shadowy shadows of medical staff and patients walking outside.

That's... what happened to everyone else?Under the effect of caffeine, Yuan Ping'an's brain began to wake up gradually.He quickly turned on his mobile phone, and after roughly browsing the work group in the courtyard, he ruled out the possibility of a large-scale public health incident.

It wasn't related to emergency work... He ran out of the door suddenly, and nervously took out his stethoscope while running - at that moment, he really thought that there might be something serious wrong with Tang Min.

Then, Yuan Pingan ran out of the door and collided with Sun Lien and others.To be precise, he hit Dr. Brunn in the stomach.Then, Dr. Brunn shook slightly, and helped up Yuan Pingan, who was lying on the floor two meters away, with a look of surprise, "What's wrong?"

Seeing his colleagues talking and laughing standing in the corridor, Yuan Ping'an felt relieved when he raised his throat.He rubbed his sore lower back from being thrown, "I thought something was wrong...why didn't you come into the office?"

"Specially leave some time for you to sleep." Sun Lien took out the notebook from his body, showed Yuan Ping'an the handwriting inside, and then said, "Go, go back and convey the spirit of the meeting to you."

　Half of the debt is paid!
