“Most of the white-collar jobs with impaired vision are carried out on the computer. Long-term exposure to the fluorescent screen will cause eye diseases such as vision loss and dry eye. Nowadays, there are not many office workers who are facing the computer for more than 10 hours a day, and we must pay attention to it! Do you remember the eye exercises when you were young? Massage the acupoints around the eyes after a long period of time to relieve visual fatigue. It is recommended that you take a short rest after using the eyes for a period of time. Do you remember the eye exercises when you were a child? Massage the acupoints around the eyes after a long time It can relieve visual fatigue. It is recommended to take a rest after using the eyes for a period of time.
White-collar workers have become a high-risk group of sudden heart disease deaths. Those who work over 3 hours a day have an increased risk of serious heart problems. So, don't ruin your body, it's not worth it. "
Xu Jiuyan looked at Brother Chuan suspiciously, and said: "Are you really okay to tell me?"
Brother Chuan shook his head and said, "I have nothing to say, just to remind you."
Xu Jiuyan learned a lot from Guan Zheng, and said, "This is what Guan Zheng asked you to tell me, right?"
Brother Chuan had no choice but to say: "Tell you the truth. Guan Zheng asked me to tell you. Just don't forget."
Brother Chuan fled and left the office. All of this made it difficult for Brother Chuan to speak. Guan Zheng is now unclear about his life and death. How should he talk to Xu Jiuyan
Guan Zheng's chest hurt all night, as if dozens of ants were biting the wound, and the body was hot and restless. Guan Zheng repeatedly had a high fever and talked nonsense. Shi Jinyu sat next to him and listened roughly. Don't run away, wait for me or something.
Suddenly Guanzheng fumbled for a while, waving his arms around, and said: "Teacher, Dad, Teacher, are you still there? Help me!"
Shi Jinyu clenched Guan Zheng's hands like ice cubes and said: "I'm still here, I'm still here, it's okay, I will protect you."
Guan Zheng slowly calmed down, and Shi Jinyu spent this day in fear again.
In the afternoon, the doctor told Shi Jinyu: "It is still a low cardiac output syndrome. This problem is really tricky. It is the final result of the imbalance between the supply and demand of myocardial energy during the hypothermic cardiopulmonary bypass. After the aorta is blocked, the metabolism changes from aerobic metabolism to aerobic metabolism. Anaerobic metabolism, energy production is sharply reduced, and it is difficult to maintain the need for normal cell metabolism. The function of 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 are damaged. During the period of ischemia and hypoxia, the hypoxia of the left ventricular myocardium is the most serious, the local metabolites accumulate, and the subendocardial microvasculature is dilated. If the myocardium is not well protected, more serious myocardial structure may occur during ischemia. Injury, cell membrane permeability increases, capillary integrity is destroyed, a large amount of water and electrolytes can enter the cell in a short time after reperfusion, aggravate myocardial edema, increase subendocardial vascular resistance, and reduce blood flow. The imbalance between the supply and demand of sub-intimal oxygen is further aggravated, and sub-intimal hemorrhage and necrosis eventually occurs.
Active use of various effective myocardial protection methods during cardiopulmonary bypass can prolong the tolerance time of myocardial ischemia and reduce the degree of myocardial edema and necrosis. Continuous perfusion with normal temperature oxygenated blood can continuously supply oxygen to the myocardium and block the myocardium during circulation. Changing from anaerobic metabolism to aerobic metabolism can avoid negative balance of myocardial energy metabolism, which is conducive to the recovery of myocardial function after surgery.
We are also actively treating. We first performed ventilation treatment of LCOS combined with hypoxemia. For some LCOS patients with refractory hypoxemia mainly due to poor lung function, appropriate pressure and time can be given under close monitoring. Positive end-expiratory pressure ventilation therapy. Then we also added blood volume, because we found pleural and abdominal effusion through B-ultrasound, so we also did puncture or drainage. In terms of drugs, we use inotropic drugs and vasodilator drugs. Dobutamine and dopamine are important drugs for the treatment of heart failure and anti-low cardiac output. They can increase cardiac output and help improve tissue perfusion and oxygenation. The two are often used in combination. There are also cardiotonics and diuretics. Milrinone can better reduce body and pulmonary circulation resistance, improve right ventricular diastolic function, and reduce the occurrence of postoperative LCOS. For severe LCOS, the combination of PDE-Ⅲ inhibitors and catecholamines can complement each other and help stabilize hemodynamic indicators. Correct acidosis, maintain water and electrolyte balance. Although LCOS is actively treated, it still has a high mortality rate, so it is extremely important to prevent the occurrence of LCOS.
But fortunately, there is no pericardial tamponade. The blood accumulation in the pericardial cavity caused by traumatic heart rupture or intrapericardial vascular damage is called blood pericardium or pericardial tamponade, which is the rapid cause of death of heart trauma. Due to the limited elasticity of the pericardium, acute pericardial hemorrhage up to 150 milliliters can limit blood return to the heart and heartbeat, causing acute circulatory failure, and then leading to cardiac arrest. So I’m really lucky. I don’t have a pericardial tamponade with such a serious complication. I should thank God. "
Shi Jinyu said: "Thank you doctor, thank you very much. But he has a high fever now, can't he keep burning, right?"
The doctor looked at the face of Guan Zheng's fiasco and said: "It's better to cool down physically. We also use medicine. I hope that he will heal faster with the combination of internal and external."
Guan Zheng was awake and lethargic from time to time, and when he was awake, he made Shi Jinyu happy, blurting out all kinds of jokes. When he was in a coma, Shi Jinyu wiped Guan Zheng's body over and over again to cool down.
Maybe it's really the husband and wife who joined the heart. They didn't show up for a few days after the government was shut down. Where did he go? Xu Jiuyan couldn't sit still, and repeatedly inquired about Guanzheng's news. Yu Shuhui was very unhappy when she saw Xu Jiuyan. Xu Jiuyan seemed to be busy every day, but most of the time she poured tea for Yu Shuhui in the office. Xu Jiuyan runs errands during the day and sorts out the evidence at night. It's harder.
Xu Jiuyan wanted to write an email to Guan Zheng, and wanted to leave a message with Guan Zheng. But when the mailbox opened, Xu Jiuyan saw Guan Zheng's letter. This email is Guan Zheng’s opinion on the case. He wrote a lot of carefully and carefully, and several attached files. Xu Jiuyan looked at the time just sent, it turns out that he has been busy with this file these days, but Xu Jiuyan is in her heart. It's warm.
Brother Chuan watched Xu Jiuyanle blooming, but he felt like a ball in his heart. Guan Zheng still didn't know what Guan Zheng was like now, and he had to do all these things by himself, which of course also meant Guan Zheng.
Shi Jinyu's heart really can't stand the toss. Guan Zheng's illness repeatedly makes people unable to stand it. How many times have I really wanted to fall to the ground and take a good rest? (End of this chapter)
