Wu Mian knew that Aunt Feng was just chatting and didn''t take it seriously. He said with a smile, "aunt Feng, if conditions permit, who will dig by hand?"


    "Xiao Wu, it doesn''t cost money to hire an excavator. You see what you said." aunt Feng chatted with Wu Mian very well. "If you hadn''t said that the free clinic for eugenics and child care, I guess the granddaughter would have been delayed."


    "Hehe, it''s OK."


    "Xiao Wu, you said you couldn''t judge if you didn''t take a look at this thing?" aunt Feng asked again, looking at the fundus mirror in Wu Mian''s hand.


    "Neither," said Wu Mian with a smile. "Let''s say, when I was a doctor, I took my younger martial brothers and sisters and called them miserable every day."


    "What are you training them for?"


    "I can''t do anything." Wu Mian said, "there is a younger student who can''t even see the films of cerebral infarction and cerebral hemorrhage. Tell me, I don''t scold them. What can I do when I go to the hospital in the future. One of these two diseases needs to stop bleeding and the other needs to activate blood. I can''t make a mistake."


    "That''s true." aunt Feng didn''t understand what Wu Mian said, but she couldn''t tell such a simple disease.


    "This is a CT. How do you guess the doctor before CT?" Wu Mian asked.


    "Yes, it was different to see a doctor at that time."


    "I am a teacher of neurosurgery and a top expert in China. I am famous all over the world. Not only in China, but also all over the world."


    Aunt Feng stared at Wu Mian, wondering what he was going to say.


    "The first CT machine in the world was only manufactured in 1972. With the active promotion of imaging leader Li Guozhen, the first CT machine in China was introduced into DIDU hospital in 1979." Wu miandao said, "now just take a film. Before CT, it mainly depends on... Guess."


    "Guess..." aunt Feng was speechless.


    Is that what doctors should say? Compared with Wu Miangang''s guess, those vague words are the gentlest love words in the world.


    "Before CT, in the face of a patient with acute cerebrovascular disease, if you want to diagnose whether it is cerebral hemorrhage or cerebral infarction, you can only guess by history. Otherwise, you can stick a needle into your brain and smoke it to see if you can pump blood."


    "..." aunt Feng was startled.


    "The scientific name of this operation is called ventriculocentesis, and now almost no one knows it. The risk is very high. Patients who can''t guess will take the risk to solve it with puncture." Wu Mian said with a smile, "puncture should be inserted around the patient''s head based on experience. If you are lucky to be inserted into the hemorrhagic focus, you can lead to the blood accumulated in the focus."


    "..." aunt Feng was silly. "Xiao Wu, you''re kidding me."


    "No, what I said is true." Wu Mian said, "or scientific progress."


    "I always think it''s strange," said Mrs. Feng. "Why do I remember that the former doctors were very powerful."


    "The survivors are deviant, and the unfortunate patients are all dead." Wu Mian said, "now there is a stroke center. Our medical university has a green channel of one water.


    It takes an average of 42 minutes for a patient to enter the hospital, receive a doctor, check his physical history, take blood tests, take oxygen infusion, take CT of the head, and use thrombolytic therapy. Of course, I''m talking about the imperial capital. The provincial capital may be a little slower, but it won''t be much slower. "


    "Is it so fast? I have the impression that it''s too slow to go to the hospital. I have to queue up all day."


    "Yes, in the age without CT, there may not be results in three or five days. Some patients die, and the doctors don''t know how to die. Tell me, how can the former doctors be more powerful." Wu Mian said, "this is not the top expert in the novel. The older they are, the more valuable they are."


    "Your teacher is not better than you," said Aunt Feng.


    "Hey." Wu Mian smiled. "My teacher said personally that I was better than the blue when I was 25 years old."


    "..." aunt Feng was speechless.


    "Let''s also say that CT patients with cerebral infarction will lose 1.9 million more brain neurons every minute. You said that without diagnosis every day, how many neurons are dead enough. You said that''s the reason."


    "It seems so, but I always think it''s strange."


    "Tell you the truth," said Wu Mian. "My teacher''s teacher is an old expert in the early days of the founding of the people''s Republic of China. At that time, there was no CT, only plain film. It was good to take an X-ray."


    "Once I caught a cold, my grandmaster... Aunt Feng, be serious." Wu Mian said when he saw that Aunt Feng was overjoyed.


    "I''ve never heard the doctor say the word" grandmaster. "Aunt Feng was overjoyed.


    "Most doctors are college students on the assembly line. At least they have to get a doctor. Hey, don''t say this. My grandfather''s X-ray is all right. Listening to the stethoscope, he found both wheezing and wet rales.


    At that time, considering that his old man often smoked and had long-term symptoms such as shortness of breath and wheezing, and the patient developed disease in autumn and winter, he was preferentially diagnosed as COPD with acute infection, that is, COPD. "


    "Well, I know the disease."


    "First anti-inflammatory treatment, but after 2 weeks of antibiotics, he didn''t alleviate, and there was a tendency to worsen. At that time, let''s rule out" pneumonia "and consider that it might be a" pulmonary tuberculosis "with less obvious clinical signs."


    "You really rely on guessing."


    "Of course, I tell you, before I became a doctor, I thought all diseases could be cured. But after graduating from University, I thought it would be good to treat half of the diseases. After graduation, I found that only 20% of the diseases could be cured. After graduation, I thought less than 10% of the diseases could be cured."


    "Now?"


    "Alas, there are really not many diseases that can be cured. Even if you give me all the most advanced instruments, many diseases still need to be guessed." Wu Mian shook his head slightly and said.


    "Aunt Feng, don''t listen to my brother." Chu Zhixi said with a smile, "he said Taiji. Ordinary minor diseases can be cured."


    Hearing Chu Zhixi say so, aunt Feng''s face looked better, "what happened later?"


    "At that time, diagnostic treatment was carried out at the same time as the test of pulmonary tuberculosis.


    But when I was admitted to the hospital, I always found that the old man had lost several kilograms of weight, and his cough symptoms were more serious. Recently, the old man had new hemoptysis, and the wheezing sound somewhere on the chest wall was more obvious by using a stethoscope. Finally... Lung cancer was diagnosed. "


    "..." aunt Feng was speechless.


    "Now, if a 64 row CT goes up and finds that there are high-density shadows, edge burrs and suspected lung cancer in the lungs. There is no need for puncture, direct surgery or interventional radiofrequency ablation, and you will be discharged three days later." Wu Mian said, "you say, if it''s your choice."


    Wu Mian looked at Aunt Feng and seriously gave her the importance of popular science instruments.
