Of course, Xia Hongyuan's illness is dangerous, and if it is not dangerous, it will not be seriously ill. But because he was worried that the parents, who were not too young, would not be able to fully understand, Sun Lien could only make his words more clear - although he himself had not had such an experience, it is said that sometimes, family members will have the idea that "this disease does not seem to be very serious" because the doctor described the condition as "not serious enough".

There is a difference between the family's thinking and the actual situation, and the worst result is that the patient is seriously ill and dies, and the family members have an emotional breakdown as if they have been struck by lightning. You may even attack the doctor directly, or complain to the end. Therefore, effectively communicating the severity of the disease to the patient's family is not only to protect the patient's and family's right to know, but also to protect the doctor himself.

"The most troublesome part of this disease is that all the blood vessels in his body are basically at risk of sudden blood clots. Sun Lien looked at Xia Hongyuan's parents who were crying silently, and felt very unbearable. The crying appearance of the two gave Sun Lien the illusion that "I turned their children from healthy to near-dead". But this is his job, and the only way to try to save Xia Hongyuan's life. "Catastrophic antiphospholipid syndrome is characterized by the fact that it is difficult to predict exactly where the blood clot will occur, and most of the locations where the blood clots occur are tiny blood vessels that are beyond the reach of our mechanical means. In other words, if a blood clot occurs elsewhere, there is basically no other way to use it than to use drugs to try to dissolve the clot. ”

Xia Hongyuan's father wiped his tears, forcibly stabilized his emotions, and listened to Sun Lien's speech. His intuition told him that this passage was probably the most important part, and that it might even determine whether his son would survive or not.

But now there is another difficulty, which is the necrosis of his small intestine. Sun Lien took out the CT imaging photos taken before, "The location you see now is Xia Hongyuan's necrotic small intestine." According to our calculations, a small part of the small intestine of about three centimeters is avascular necrosis - the cause is probably capillary thrombosis. ”

"But, haven't you already used the medicine?" Xia Hongyuan's mother couldn't help it, she asked loudly, "After using the medicine, after the blood clot is dissolved, isn't it all right?"

"After the clot is dissolved, the blood can re-enter those organs. But cells that have died do not come back to life. Sun Lien shook his head, "What's even more terrifying is that after re-entering the dead organ part, the blood may carry a large amount of waste and even toxic substances. This will have a more serious impact on Xia Hongyuan's body. But in order to relieve uncontrollable pain and other symptoms, we must first dissolve the blood clot. This means that his body is currently in a state where blood cannot clot smoothly – which prevents us from operating on his necrotic intestines. ”

Xia Hongyuan's mother covered her mouth.

"But in his case, we still believe that surgery is a more realistic and appropriate treatment. Yuan Ping'an interjected, "However, with his current condition, it is too risky to perform open surgery." There may be a risk of heavy bleeding during the operation, which can directly endanger his life. So we decided to use a safer method to replace the plasma in his body with plasmapheresis. This can reduce the amount of heparin in his blood, and at the same time, it can also control the abnormal antibodies in his blood, which are the main cause of Xia Hongyuan's abnormal blood clotting. ”

"In other words, this treatment will not only prepare his body for surgery, but also treat his current problems?" Xia Hongyuan's father's voice was a little more stable, and this treatment seemed to be the most suitable for his son.

"Yes. "This time it was Dr. Pascal's turn to speak. "Plasma exchange is a very effective way for us to deal with diseases of our own immune system. At the same time, through the use of hormones and immunosuppressants, theoretically, we should be able to suppress the abnormal immune antibodies in his body to a very low level, so as to control the disease. ”

Dr. Pascal's words contain two of the family's least favorite words to hear, "theoretically" and "should." The appearance of these two words means uncertainty. And when this uncertainty happens to one's loved ones, it means that life is in danger. No one can readily accept that their relatives are worried about their lives, and Xia Hongyuan's parents are naturally no exception.

"Why should it be?" Xia Hongyuan's mother was anxious, "You are doctors, don't you know if you can't cure a good disease?"

There was an awkward silence in the small conference room. Sun Lien was silent for a while and then replied, "That's why we're going to issue a serious illness notice - this disease is very dangerous, and it's ...... There is still no perfect treatment plan in medicine. What we can't be sure of is not whether it can be cured or not, but whether Xia Hongyuan has a good enough response to this treatment. ”

Xia Hongyuan's mother seemed to have something to say, but was stopped by her husband, who had calmed down.

"I know that you doctors, you don't usually dare to talk too much. Xia Hongyuan's father asked with red eyes, "But, at least can you tell us first, he ...... What are his chances of surviving?"

Sun Lien had a bitter face, desperately wondering if there was a gentler way to explain. And Xu Yourong, who had been silent, suddenly spoke.

"According to the current statistics, the mortality rate is about 50%. Xu Yourong said calmly, "Actively receiving treatment, he probably has half a chance of surviving." ”

"This is the statistics of your hospital?" Xia Hongyuan's father's question was almost straightforward to the point of being rude, "Will it be better to go to other hospitals?"

"That's a statistic for the entire medical community. Of course, there may be some lag in the data. Xu Yourong's answer was still calm and ruthless, "After all, in the previous statistics, there may not be the impact of plasmapheresis." But we can't estimate how big this impact will be, so let's calculate it on a half-and-half basis. ”

Sun Lien sighed, and let Xu Yourong continue to talk like this, maybe he would have to fight, "As for other hospitals—there must be hospitals that are better at treating autoimmune diseases than us." But the problem is that the hospitals that can be stronger than us are all outside the province. It is mainly concentrated in the capital and Shanghai. Transferring to these two places, even by helicopter, would take at least six hours. It's hard to say whether there will be other variables in these six hours - the anticoagulant drug we used for Xia Hongyuan is low molecular weight heparin sodium, which will decay by half in about three and a half hours in the human body. After six hours, the concentration of the drug drops to at least a quarter of what it is now. If clotting occurs during the descent, it can be fatal. ”

"We are doctors, probably the people in the world who want their patients to recover the most, apart from their families. "Yuan Ping'an used to see the families of these patients who wanted to be transferred to the hospital for treatment when he was in the association. "Whenever there is an opportunity to get a better outcome through a hospital transfer, we will not hesitate to bring it up. However, now the risk of transferring to the hospital for treatment is even greater for Xia Hongyuan. And when it comes to the treatment of this disease, there is really no better means in other hospitals. ”

The words had already been said very clearly, and Xia Hongyuan's parents fell silent as they looked at the serious illness notice in front of them.
