Open an aircraft carrier to fight against Japan

The officer nodded and went.In order to find a place for Chen Xin to see a doctor, Lin Yuan specially asked someone to buy a big house. When he was outside, Lin Yuan ordered: "Secretize the five miles around this big house, and no one is allowed to approach it."

After the sentries were deployed, Lin Yuan brought Cixi and a group of guards into the house. Lin Yuan made people wait outside, and went in to find Chen Xin. Chen Xin was already waiting in the house. She was wearing a The white coat looks like a fairy in this era. Lin Yuan said to her: "The patient has arrived, but there are some troubles on the way, so you must be optimistic this time!"

Chen Xin smiled softly and said, "Don't worry, I've seen many cases of cataract, and it's not a problem."

Lin Yuan came out and said, "The fairy is ready, you can go in."

Cixi nodded and winked at Li Lianying. Li Lianying opened the door and went in. Chen Xin smiled at him. Li Lianying turned around and went out. When she came back, she said to Cixi: "Reporting to Lafayette, that's right, please come with Master Tianlin." The gods look exactly the same."

Lin Yuan said: "Since there is no problem, please go in."

Cixi took Li Lianying in, and Lin Yuan waited outside. After a while, Chen Xin came out from inside, her face was full of worry, Lin Yuan quickly asked, "What's wrong?"

Chen Xin pulled Lin Yuan aside and said, "I thought her illness was not serious, and I just needed to be prescribed some medicine, but now it seems that her illness must be operated to be effective."

Lin Yuan said: "Surgery? If she sees you holding a scalpel, she will definitely think you are an assassin!"

Chen Xin nodded and said: "I don't actually need a scalpel. We have an ultrasonic cataract emulsification device here. You only need to make a small incision on the eye, and the ultrasonic wave can emulsify and absorb the deteriorated crystals, and then you can implant them." Putting in a whole new lens, my real concern is the anesthesia process."

Lin Yuan asked: "What's so scary about the anesthesia process?"

Chen Xin said: "You are not a doctor. You don't know that many patients are not afraid of the scalpel. On the contrary, they are afraid of the anesthesia needle. The needle used for anesthesia has a very long needle. Needles go into the body."

"And the anesthesia process for cataract surgery is even more terrifying, do you know? There are two types of anesthesia, one is general anesthesia, which simply means that people are unconscious; the other is local anesthesia, that is, only the part to be operated is unconscious, cataract The operation is usually performed under local anesthesia, and the anesthesia needle is placed near the eyeball, and from the perspective of the patient, the anesthesia needle is piercing the eye straight!"

"A steel needle pierces the eye. You say you are not afraid. Some patients need general anesthesia for a small cataract operation because of this reason."

Lin Yuan asked, "What kind of anesthesia is general anesthesia?"

Chen Xin said: "There is inhalation anesthesia, that is, the inhalation of hypnotic gas, such as laughing gas, isoflurane, etc., which seems to be the most comfortable way of anesthesia; there is also injection anesthesia, which also requires injections."

Lin Yuan asked: "Then why don't you give her general anesthesia too? Why, didn't you bring that anesthetic?"

Chen Xin looked at Lin Yuan helplessly, as if looking at an ignorant child, and said, "Do you believe that anesthesia can kill people?"

Lin Yuan replied: "Of course, if you use too much, you will definitely die."

Chen Xin shook his head and said, "I'm talking about the proper dosage."

Lin Yuan thought for a while, then shook his head, Chen Xin said: "During general anesthesia, the muscles connecting the stomach and esophagus will become loose, so the food in the stomach cannot be locked, and the food in the stomach will flow back down the esophagus." To the mouth, in the human mouth, food enters the esophagus and air flows into the lungs at the same place, but people never swallow food into the trachea."

"This is because during the evolution of millions of years of animals, a swallowing reflex has been formed. When food enters the mouth, people will swallow it into the esophagus. However, during the process of general anesthesia, the swallowing reflex disappears, so the food will be swallowed. It enters the trachea and flows to the lungs, and then it will cause suffocation and death. This is the reflux phenomenon that needs to be prevented during surgery. Therefore, you can’t eat before general anesthesia. The Empress Dowager Cixi must be full to come. Yeah, how can we use general anesthesia?"

Lin Yuan said: "Then we let her sit, won't the food not flow up?"

Chen Xin shook his head and said, "It's useless, there is pressure in the stomach, which can push food up."

Lin Yuan asked: "So you mean, you can only use local anesthesia for surgery?"

Chen Xin nodded, Lin Yuan thought for a while, and said, "Do you think this Cixi has ever been beaten?"

Chen Xin asked suspiciously: "Why do you ask this?"

Lin Yuan said, "I'll go in and knock her out with a punch, and then you take the opportunity to inject anesthesia into her eyes."

Chen Xin opened his mouth in surprise, and said, "How dare you knock Empress Dowager Cixi unconscious! Are you not afraid that she will retaliate against you?"

Lin Yuan smiled and said: "When I was training at the air force base, such a thing happened. Once we were practicing the [-]-meter sprint. When I was running, an instructor suddenly walked up on the runway. I couldn't dodge it and hit him with an elbow. In front of him, the teacher was directly knocked unconscious by me."

"That time scared me, you know? The teacher didn't like me, and he would give me a few words from time to time. I thought it was over, I knocked him out, and he would find fault with me in the future. Yes, but when he woke up, guess what happened?"

Chen Xin asked, "What happened?"

Lin Yuan said: "The first thing he did after he got up was to touch his head and ask the people around him what happened. When others asked him, he couldn't remember what happened. At that moment, people will have short-term amnesia, so if I give Cixi a moment, she won't remember it."

Chen Xin instructed: "You must be careful, she is already 61 years old, if your hand is any heavier, she will die."

Lin Yuan said: "I will be careful." When the two returned to the house, Lin Yuan said to Cixi: "Can you let Manager Li go out first and wait for a while."

Cixi nodded in agreement, Lin Yuan waited for Li Lianying to leave, then locked the door, stretched out his hand and slapped Cixi on the back of the neck, Cixi's head drooped, and she fainted immediately, Chen Xin immediately rushed forward, opened her eyelids, I took a flashlight to shine on her pupils, and saw that the pupils were dilated normally, and then said: "It's okay, you beat her well, she passed out."

Only then did Lin Yuan let go of the stone in his heart, and Chen Xin said, "Hold her down, and I will give her an anesthetic." Lin Yuan fixed Cixi on the chair, and Chen Xin opened her eyelids, injected the anesthetic, Then he handed a sponge ball to Lin Yuan and said, "Help her press the eyes, once every ten seconds, three seconds each time! Last for 10 minutes."

Lin Yuan frowned and asked, "Why is it taking so long?"

Chen Xin said: "Ten minutes is too long! Some operations require two to three hours of anesthesia alone!"

Lin Yuan said, "I'm afraid the people outside the door won't be able to wait that long."

Chen Xin said: "There is no way, the operation must be done in this way, otherwise it will be fine!" As Chen Xin said, he turned on the emulsification machine, held the probe in his hand, and prepared for the operation.

At this moment, an anxious shout sounded from outside the door: "Lafayette, how are you? Say something, let this servant hear your voice."
