"As for the harm, do you want to listen?" Guan Zheng asked tentatively.

Shi Jinyu said: "Don't you say that I can access Baidu." ”

Guan Zheng was entangled for a moment and said, "Then let's talk about it." Vegetations consisting of platelets, fibrin, red blood cells, white blood cells, and deposition of infectious pathogens are attached to the surface of heart valves. The latter may extend to the chordae tendinae and the lining of the ventricular wall. Growths in various parts of the heart may heal to varying degrees, from one part of the body to active inflammation elsewhere, and some can recur and re-form lesions. When the lesion is severe, the heart valve can form a deep ulcer or even perforate.

The vegetations of this disease are larger and brittle than those produced by rheumatic endocarditis, and are easy to break into infected embolism, which spreads to all parts of the body with the large circulation blood flow and produces embolism, especially the arteries of the brain, spleen, kidneys and limbs, causing infarction or abscess of the corresponding organs. Embolization obstructs blood flow or destroys the walls of blood vessels, causing cystic dilation of the walls to form bacterial aneurysms, often fatal complications. For example, if an artery in the brain causes an aneurysm to thrive a vessel, it can often rupture suddenly, causing intraventricular or subarachnoid hemorrhage and death. Diffuse meningitis is more common than brain abscess.

Microthrombosis or small vasculitis due to immune mechanisms is common. The infectious organism and the corresponding antibodies produced in the body bind to the immune complex and settle on the basement membrane of the glomeruli, causing focal glomerulonephritis or diffuse or membranous proliferative glomerulonephritis, which can cause renal failure. ”

Shi Jinyu nodded and said, "Very good, the problem is here, what is the solution?" ”

Guan Zheng said with a little humility: "Well, it's to take antibiotics, or surgery to replace materials." ”

"Have you forgotten a word?" Shi Jinyu's question also stunned Guan Zheng.

Guan Zheng asked, "Is there anything else?" ”

"Yes, there is usually a saying that early treatment will increase the cure rate." Shi Jinyu said lightly.

Guan Zheng smiled and said, "Yes, I almost forgot about it just now." ”

"Huh?" Shi Jinyu asked with a squint.

Guan Zheng lay on the table and said to Shi Jinyu: "I'm tired, let me lie down for a while." ”

Shi Jinyu finally didn't give up and said, "Okay, I'll pour you a glass of boiled water." ”

After pouring a glass of water, Guan Zheng seemed to be asleep. Shi Jinyu felt that something was wrong, so he called: "Guan Zheng, Guan Zheng, wake up and go to bed." ”

shouted a few times, but Guan Zheng didn't wake up. Shi Jinyu secretly screamed badly, and immediately put Guan Zheng in the car and rushed to the hospital.

When the doctor on duty was called up at night, not only the doctor on duty was unhappy, but the nurse was also unhappy.

The doctor on duty looked at Guan Zheng's face very badly, and instantly sobered up a lot, and said, "What's the patient's condition?" ”

"I was discharged from the hospital this morning, a little more than a week after heart repair surgery." Shi Jinyu said quickly.

The doctor on duty was agitated, hung up a drip, put on various instruments, sweated profusely, and said: "You parents are too indulgent, right, now young people are under a lot of pressure and busy with work, but they can't stay in the hospital for a few more days, right?" Normally, you would be discharged from the hospital in about two weeks, but you're only a week, and there are four days in the intensive care unit here, so you can see for yourself. But what about Guan Zheng, this young man, heart surgery is okay, it can be regarded as a success, but the postoperative infection is more serious, some bacterial infections, and other effects, I think the patient is too stressed, overworked, right? This is not conducive to recovery. ”

Shi Jinyu listened to the doctor's complaint 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 your future life?" ”

Shi Jinyu said: "He doesn't do things to accumulate capital, but for conscience!" ”

The doctor was stunned for a moment and said, "Conscience is not as important as life." ”

Shi Jinyu didn't say anything, but looked at Guan Zheng. The doctor said lightly: "It can be seen that you love him very much, but as a father, it is more important for him to live a healthy life than to be prosperous and rich." ”

Shi Jinyu nodded and said, "Thank you, doctor." ”

"It's okay, I'll get busy first." After the doctor left, Shi Jinyu pulled a chair and sat down on the edge of the bed, as if talking to himself: "If you don't listen to the old man, you will suffer in front of you, now you know, right?" ”

Guan Zheng is like a sleeping child, lying there peacefully, not worrying about the case, not having to think, not having to be afraid, such a time is beautiful.

Shi Jinyu was startled by the sharp scream of the ECG monitor, and the nurse next to him was also awakened and hurriedly called the doctor over.

The doctor looked at the mess of data and said, "Adrenaline mg, hurry, hurry!" ”

Shi Jinyu stood not far away, watching the doctors come and go, they didn't understand what they said, and remembered that the doctors and nurses were all going around until the ECG monitor stopped ringing.

The doctor took off his mask, took a deep breath, and said, "My mother, this night, scared the living to death!" But this kid's life is so good, he survived such a difficulty. ”

Shi Jinyu only heard the doctor's words clearly at this time, and then said: "Yes, he is like a grass growing in the cracks of the stones, strong and optimistic. ”

The doctor pointed to the scar on Guan Zheng's wrist and said, "What is this?" It can't be caused by suicide, right? ”

Shi Jinyu shook his head and said, "Of course not, this is a life bet." ”

The doctor didn't go back to the lounge, and sat in the emergency room with Shi Jinyu, looking at Guan Zheng. Shi Jinyu opened his mouth and asked, "He, how is it now?" ”

The doctor said, "It's still low cardiac output syndrome, complicated by postoperative infection." Low cardiac output syndrome is the final result of the imbalance between myocardial energy supply and demand during the cryogenic cardiopulmonary bypass, and the metabolism changes from aerobic metabolism to anaerobic metabolism after aortic blockade, and energy production is sharply reduced, making it difficult to maintain the normal metabolism of cells. The function of the cell membrane sodium pump is impaired, and a large number of sodium ions are retained in the cells, causing myocardial edema. Cardiomyocytes are damaged by increased lactate, an anaerobic metabolic end product, resulting in intracellular acidosis. The left ventricular submyocardial hypoxia is most severe during ischemia and hypoxia, with local metabolites accumulating and subendocardial microvascular dilation. Poorly protected myocardium, during the ischemic period, more serious myocardial structure damage can occur, the permeability of the cell membrane increases, the capillary integrity is destroyed, a large amount of water and electrolytes can enter the cells in a short time after reperfusion, aggravating myocardial edema, increasing the subendocardial vascular resistance, reducing blood flow, further aggravating the imbalance between supply and demand of submetrial oxygen, and finally subintimal hemorrhage necrosis. To put it bluntly, there is not enough blood. ”
