"As for the harm, do you want to listen?" Guan Zheng asked tentatively.
Guan Zheng tangled for a moment and said, "Let me just say it. On the surface of the heart valve are attached vegetation composed of platelets, fibrin, red blood cells, white blood cells and the deposition of infectious pathogens. The latter can extend to the chordae chordae and the lining of the ventricular wall. The degree of healing of neoplasms in various parts of the heart varies. One place may be healed, but the inflammation in other places is in an active phase, and some can recur after healing and re-form the lesion. When the disease is severe, the heart valve can form deep ulcers. , And even perforation occurs.
The neoplasms of this disease are larger and more fragile than those caused by rheumatic endocarditis, and are easily broken into infection emboli, which spread to various parts of the body with the general circulation of blood to cause embolism, especially the brain, spleen, kidney and limb arteries. Many, cause infarction or abscess of the corresponding organ. Embolism hinders blood flow, or destroys the blood vessel wall, and the cystic expansion of the vessel wall forms a bacterial aneurysm, which is often a fatal complication. For example, aneurysms caused by embolization of nourishing blood vessels in the arteries of the brain can often rupture suddenly and cause intracerebroventricular or subarachnoid hemorrhage leading to death. Diffuse meningitis is more common than brain abscess.
This disease often has small vasculitis caused by microembolism or immune mechanism. Infecting pathogens and the corresponding antibodies produced in the body combine to form immune complexes, which are deposited on the basement membrane of the glomerulus, causing focal glomerulonephritis or diffuse or membranous proliferative glomerulonephritis, which can cause kidneys Functional failure. "
Shi Jinyu nodded and said, "Very well, the problem is coming, what's the solution?"
Guan Zheng said with a guilty conscience: "Uh, it's just taking antibiotics or surgical replacement of materials."
"Have you forgotten a sentence?" Shi Jinyu stunned Guan Zheng by this question.
Sekisei asked, "Are there any more?"
"Yes, there is usually a saying, early treatment will increase the cure rate." Shi Jinyu said lightly.
Guan Zheng smiled and said, "Yes, I almost forgot."
"Really?" Shi Jinyu asked, squinting.
Guan Zheng lay down on the table and said to Shi Jinyu like a baby: "I'm tired, let me lie down for a while."
In the end, Shi Jinyu didn't get serious and said, "Okay, I'll pour you a glass of boiled water."
After pouring a glass of water, Guan Zheng seemed to fall asleep. Shi Jinyu felt that something was not right, so he called: "Guanzheng, Guanzheng, wake up, go to sleep."
After shouting a few times, Guan Zheng did not wake up. Shi Jinyu cried secretly, put Guan Zheng into the car and rushed to the hospital.
Calling the doctor on duty at night, not only was the doctor on duty unhappy, but the nurse was unhappy.
The doctor on duty looked at Guan Zheng with a very different face, and instantly became sober a lot, and said, "What is the patient's situation?"
"He was discharged from the hospital this morning, a little more than a week after the heart repair operation." Shi Jinyu said quickly.
The doctor on duty was agitated, hung up a drip, put on various instruments, and was busy sweating profusely, saying: "You parents are too indulgent. Now young people are under a lot of pressure and are busy with work, but they are not. It’s not okay to stay in the hospital for a few more days, right? Normally, you will be discharged from the hospital in about two weeks. You are only a week, and there are four days in the intensive care unit. You can see this for yourself. But what about the boy Guanzheng, Heart surgery is okay. Many people have been successful, but the postoperative infection is more serious, part of the bacterial infection, and other effects. I think the patient is too stressed and overworked? This is not conducive to recovery."
Shi Jinyu heard the doctor complain and said, "I was negligent."
The doctor sighed and said, "Actually, this is all normal. When you are young and vigorous, who doesn't want to accumulate some capital for future life?"
Shi Jinyu said: "He doesn't do things for the purpose of accumulating capital, but for his conscience!"
The doctor froze for a moment, and said, "Conscience is not more important than life."
Shi Jinyu didn't say a word, but looked at Guan Zheng. The doctor said lightly: "You can see that you love him very much, but as a father, letting him live a healthy life is more important than prosperity and wealth."
Shi Jinyu nodded and said, "Thank you doctor."
"It's okay, I'll go busy first." After the doctor left, Shi Jinyu pulled up a chair and sat down by the bed, as if to say to himself: "If you don't listen to the old man, you will suffer. Now you know?"
Guan Zheng is like a sleeping child, lying there peacefully, without worrying about the case, without thinking, without being afraid, it's a beautiful time.
Shi Jinyu was startled by the sharp cry of the ECG monitor, and the nurse next to him was also awakened, so he hurriedly called the doctor.
The doctor looked at the messy data and said: "mg of adrenaline, fast!"
Shi Jinyu was standing not far away, watching the doctors coming and going. They didn't understand what they said, remembering that the doctors and nurses were all wearing them until the ECG monitor stopped beeping.
The doctor took off the mask, took a deep breath, and said, "My God, this night, I scared the living! But this kid is so fate, so difficult, he has survived."
Only then did Shi Jinyu hear the doctor's words clearly, and then said: "Yes, he is like a grass growing in a crack in the rock, strong and optimistic."
The doctor pointed to the scar on Guan Zheng's wrist and said, "What is this? Can't it be caused by suicide?"
Shi Jinyu shook his head and said, "Of course not. This is a bet on life."
The doctor did not go back to the lounge, and sat in the emergency room with Shi Jinyu, looking at Guan Zheng. Shi Jinyu asked, "How is he now?"
The doctor said: "It is still low cardiac output syndrome, combined with postoperative infection. Low cardiac output syndrome is the final result of the imbalance between myocardial energy supply and demand during hypothermic cardiopulmonary bypass. After the aorta is blocked, the metabolism changes from aerobic metabolism to anaerobic metabolism. Metabolism, energy production is drastically reduced, and it is difficult to maintain the normal metabolism of cells. The function of the cell membrane sodium pump is impaired, and a large amount of sodium ions stay in the cell, causing myocardial edema. The increase of anaerobic metabolism end product lactic acid causes intracellular acidosis, which makes myocardial cells Damaged. During the period of ischemia and hypoxia, the hypoxia of the left ventricular myocardium is the most serious, local metabolites accumulate, and subendocardial microvasculature is dilated. If the myocardium is not well protected, severe myocardial structural damage may occur during ischemia. The permeability of the cell membrane increases and the integrity of the capillaries are destroyed. After reperfusion, a large amount of water and electrolytes can enter the cells in a short time, aggravate myocardial edema, increase the subendocardial vascular resistance, reduce blood flow, and reduce the intima The imbalance between the supply and demand of oxygen is further aggravated, and eventually subendometrial hemorrhage and necrosis occurs. To put it bluntly, it means that there is not enough blood." (End of this chapter)
