It's still very cold in Ningyuan today, with snowflakes floating in the sky. It's so cold that it could freeze Ma Guoqun's feet into third-degree frostbite within four hours. However, it is obviously outdoors, and the door of the Nuclear Medicine Department of the Fourth Central Hospital is crowded with people. Many people.
After receiving the news, doctors and students from the Department of Imaging, Department of Nuclear Medicine, Department of Infectious Diseases and School of Public Health Management gathered together. They were all particularly curious about this Gamma Knife program. From a certain point of view, this time
The nature of the treatment plan is the same as that of the 3D printing atlantoaxial vertebra replacement surgery performed by Capital Tonghe. Both are treatment plans that have been performed on the human body for the first time. And compared to the atlantoaxial vertebra replacement surgery, the gamma knife plan is actually more difficult and risky.
big.
Radiation is required to be in place at once, while surgery can adjust the surgical plan as the process progresses. This alone makes the Gamma Knife plan immediately distanced from replacement surgery. One can be adjusted slowly and tried, while the other is a one-time deal.
What's more, the Gamma Knife plan is not even proposed by a specialized oncology or infectious disease hospital. It is a treatment plan proposed by a large comprehensive emergency center!
The Nuclear Medicine Department has never been the leading department of large emergency central hospitals. Even though the Fourth Central Hospital is a key point in the province and is also a regional demonstration unit, the Nuclear Medicine Department of the Fourth Hospital is only barely ranked in the annual rankings.
It's just "nominated", it can't even make it into the top five in the region.
If you want to use an analogy, this feels like the Shanghai Mental Health Center is preparing to perform atlantoaxial replacement surgery before the Capital Tonghe Association. Although the Mental Health Center is also a comprehensive tertiary hospital, and its strength is not weak, they still
It can be ranked among the top 100 hospitals in the country. However, such difficult spine surgery and neurosurgery are not their main focus, and their department's "industry reputation" does not support their rashness.
to do this kind of surgery.
But after all, a large emergency center is different from a mental health center. Yang Jianqiang’s treatment is imperative, and he does not dare to delay it at all. The attending doctor on duty at the Nuclear Medicine Center simply does not dare and is not qualified to take action. So he first made a phone call.
He asked the deputy director, and as soon as the deputy director heard about the treatment plan, he simply took the director out of the house.
Although Director Zhao Hua of the Nuclear Medicine Center has rich experience, emergency gamma knife treatment required him to irradiate brain Toxoplasma lesions without adequate assessment. This kind of thing he had never done before made him feel a little unsure.
In line with the principle of "the more you watch the excitement, the less panic you will feel", Director Zhao Hua made a few phone calls and called two professors from the School of Infectious Diseases and Parasitology of Ningyuan Medical College. At the same time, he also invited two professors from the School of Infectious Diseases and Parasitology of Ningyuan Medical College.
Although Professor Zhang from the Military Preventive Medicine School of the PLA is engaged in medical protection research, his doctoral supervisor is a nationally renowned expert in radiation sickness research.
It’s good to be a check!
Director Zhao Hua was calling for foreign aid, while on the other side, Zhou Jun and the others were also seeking support from industry experts as much as possible. The calls for help came one after another, and they even finally found the chairman of the Military Nuclear Medicine Professional Committee of the Fourth Military University.
Director Wang Hongjing. After a series of calls for help, the number of medical staff who decided to visit gradually increased to more than 50 people now.
In this group of people, there are about ten professors and seven or eight associate professors. Except for Sun Lien, the one with the lowest degree is also a master's degree student. Sun Lien, who has never been considered a top student, stood on the outside of the crowd. I don't know if it is because the weather is too cold or because
Suppressed by the aura of being a top student, his hands actually trembled a little.
"Is it so lively?" Sun Lien was shaking like a Parkinson's patient next to the crowd. Director Wang Jianpei, who came to watch the excitement, saw this kid at a glance. Director Wang has been eating mutton vermicelli soup three times a day since he installed the takeout app on his mobile phone.
The food was so comfortable. Naturally, Sun Lien was also very pleased with it. Now he saw that Sun Lien was a little out of place with the surrounding environment, so he came over and patted him on the shoulder with a smile. "This place with many people should be warm."
Yes, why are you so frozen? You didn't even bother to eat?"
"Director Wang." Sun Lien nodded quickly towards Wang Jianpei. In terms of seniority, this is his future uncle, and he cannot neglect his etiquette. What's more, Director Wang has a great appetite, and he killed Sun Lien in one meal last time.
It’s almost 200 yuan. If I get picked on again, it would be very bad. “I...I’m just a little nervous.”
"Why are you nervous?" Wang Jianpei was a little puzzled, but then laughed, "It's not like you go on stage to get a Gamma Knife. Just watch the excitement."
Sun Lien answered honestly, "This treatment plan... I told Director Zhou to talk about it..."
"Director Zhou?" Wang Jianpei frowned and pondered for a while before he realized that Sun Lien was talking about Zhou Jun. Then he asked curiously, "Did you come up with the idea of ​​irradiating Toxoplasma gondii with the gamma knife?"
Wang Jianpei's loud voice carried far away along the cold north wind. Many experts present immediately turned their heads and looked at Sun Lien and Wang Jianpei curiously. In particular, more people paid attention to Sun Lien. Everyone seemed to want to take a look.
, how many arms and legs does a doctor who dares to use this treatment method risk his life to have?
Sun Lien was already nervous, but when he was stared at by these big guys, his hands trembled even more. But before it was his turn to defend himself, a flatbed truck was pushed out from the passage next to the tarmac.
There were many doctors in white coats surrounding. They held up two white sheets on top of the flatbed truck with their hands, and followed the flatbed truck like a mobile tent. Zhou Jun was pushing the cart at the back, while Liu Pingchuan and others were
Other nurses holding white sheets nervously monitored the cardiopulmonary monitor placed next to the bed.
Yang Jianqiang had a tube inserted into his mouth. When Sun Lien saw this moment, he felt a chill in his heart.
Could it be that the cerebral edema area at the base of Yang Jianqiang's skull has squeezed into the brainstem, causing his breathing to be suppressed?
Taking a closer look, Sun Lien felt a little relieved. Although the tube was inserted into the throat, it was not connected to a respirator commonly known as a "ball". It seemed that they were preparatory measures to prevent the condition from worsening, and that in case Yang Jianqiang showed signs of breathing,
Exhaustion symptoms, this can at least buy some time for intubation.
Mrs. Yang walked at the front of the team. She was like a Valkyrie in Nordic mythology, holding up the umbrella in her hand like a sword, trying her best to block the wind and snow for the doctors behind her and her husband.
"You are quite fast." The group of people walked to the door of the Nuclear Medicine Center. Zhou Jun raised his head and saw Sun Lien standing at the outermost side of the team. He waved to Sun Lien, "For the patients you diagnosed, you mentioned
"What's wrong with the treatment plan? You just pretended to be okay when things happened?" Zhou Jun pretended to be angry, "Why don't you come over and push the bed quickly?"
The senior brother was angry, and of course he had to show off. Sun Lien ran to the bed in three steps and started pushing the bed with his head lowered. The gazes directed at him by the top students around him seemed to become a little more intense.
The radiation treatment plan for Gamma Knife has been finalized during discussions in the conference room. Considering that there is only one chance of treatment, experts from the Fourth Central Hospital did not adopt a relatively conservative approach after extensively soliciting opinions from professionals in the industry.
The total radiation dose is 170gy/min for the abscess area, 80gy/min for the edema area, and the total radiation dose is 1000gy.
This amount of radiation exceeds five times the dose prescribed for the general clinical treatment of brain tumors. It is extremely risky for any patient to receive such a large dose of radiation. Although the gamma knife has an accurate radiation area, it is not suitable for other patients.
It has the characteristics of small organ damage. However, it still cannot completely prevent the patient's remaining tissues from being affected. And this effect will be more obvious especially under huge amounts of radiation.
For Yang Jianqiang, there are three most fatal risks of gamma knife. The first is that the radiation may cause serious damage to his small intestinal villi, which is also the main cause of most acute radiation sickness. The second is the large dose.
Delayed microvascular damage that may occur after radiation. When this damage occurs in the brain area, microvascular edema is likely to occur, leading to cerebral thrombosis or insufficient blood supply. The third risk is under high-dose radiation
, may cause associated brain tissue death.
Of the three risks, the first can be avoided by precisely controlling the scope of radiation influence, and the second can be avoided by strengthening anticoagulation after treatment. However, the third risk is somewhat difficult to deal with.
The main way to avoid the third risk in clinical practice is multiple irradiation. The tolerance of normal brain tissue to radiation is actually stronger than that of tumor tissue. Irradiation of about 80gy will cause fatal damage to tumor tissue, but for
The impact on normal brain tissue is not that serious. Generally speaking, about six hours after irradiation, the brain tissue affected by 80gy dose irradiation can begin to repair itself. Therefore, when treating larger or multi-focal brain tumors,
During the period, the radiation treatment course is usually divided into three or even longer phases. A certain amount of radiation is received every day to protect normal tissues and kill tumors at the same time.
But Yang Jianqiang does not have this opportunity. No one knows whether multiple radiations have enough killing effect on Toxoplasma gondii. And it is unlikely that he will have the opportunity to split the number of treatments. For him, there is only one chance to survive or die.
Chance. If one dose of radiation can suppress Toxoplasma gondii, he may still survive. If the radiation is too strong and causes serious complications, or if the radiation intensity is not strong enough and Toxoplasma gondii continues to reproduce, Yang Jianqiang will be dead.
Sun Lien, Zhou Jun and others sent Yang Jianqiang to the gamma knife bed. Several young and strong male nurses worked together to lift him to the bed. The rest of the work had to be left to professionals. Sun Lien and Zhou
Jun got into the rest room outside the Gamma Knife treatment room together, and the two of them drank tea uneasily. There must be something wrong with the hot water machine in the Department of Nuclear Medicine. The temperature of the water used to make tea is not even as hot as the water for soaking feet.
