Can pneumoconiosis be cured by changing lungs?

However, there are only a handful of hospitals in China that can do lung transplantation, and the effect is not good, and the mortality rate is extremely high, because the lung is the organ with the strongest rejection in the human body, and the lung has a reticular membrane structure. Not after rejection, the human body will die of lack of oxygen. In addition, when transplanting a lung, after one lung is removed, the other lung can temporarily assume the respiratory function of the human body, which buys some time for the operation and is relatively less dangerous. When two lungs are transplanted at the same time, it is difficult to ask the newly replaced lung to start working immediately within two or three minutes. Therefore, changing lungs should be carefully considered.

Pneumoconiosis is a systemic disease mainly caused by diffuse fibrosis (scar) of lung tissue caused by long-term inhalation of productive dust in occupational activities. In severe cases, symptoms such as cough, expectoration, chest pain and dyspnea occur. Pneumoconiosis patients should be treated comprehensively according to the needs of their illness, and actively prevent and treat complications such as tuberculosis, so as to relieve symptoms, delay the progress of their illness, prolong their life and improve their quality of life. At present, conservative symptomatic treatment is still adopted, and try not to change lungs.

Successful cases of lung exchange:

West China Daily reported: "On September 1 1, 2007, news came from west china hospital that the first double lung transplant operation in Sichuan was successful. Huang Yi, a patient with complete pulmonary fibrosis, successfully put on a new lung before his birthday. At present, the function of both lungs has returned to normal, and the patient can be discharged in a few days. The success of the operation also indicates that patients with lung diseases such as end-stage emphysema and pulmonary fibrosis will be treated. "

According to Yangzi Evening News, in 2005, Chen Ting, a 26-year-old girl from Wujiang, Suzhou, was diagnosed with mixed connective tissue disease, which led to severe pulmonary fibrosis. She struggled with the disease for nearly eight years and was sentenced to death by the doctor, with only three months left at most. The only chance to prolong life now is a lung transplant. April 20 12, she met a "Bo You" who successfully received a lung transplant in Wuxi People's Hospital in Weibo. From there, Chen Ting learned that lung transplantation in Wuxi People's Hospital is very professional and authoritative. So, with a glimmer of hope, Chen Ting found Chen Jingyu, a national lung transplant expert in Wuxi People's Hospital, through Weibo. The situation in Chen Ting is very special and complicated. She is the first patient with pulmonary fibrosis secondary to mixed connective tissue disease who received bilateral lung transplantation in China. "She has been ill for more than 7 years and has been using high-dose hormones to treat fibrous heart failure. Lung transplantation is the last chance ... "Chen Jingyu wrote in Weibo.

God always thinks of Chen Ting, a brain-dead patient who donated his lungs. 12 at noon on August 5th, Chen Ting was pushed into the operating room. After the operation, Chen Jingyu "restored" the operation process in Weibo: she was accompanied by pulmonary hypertension and right heart failure due to fibrosis, and we gave her extracorporeal membrane oxygenation assisted artificial heart-lung machine. Extracorporeal membrane oxygenation is a kind of extracorporeal circulation, which replaces the traditional extracorporeal circulation. After resection of a lung, the ventilation function of the remaining lung is insufficient or the pulmonary circulation resistance of the remaining lung is too large, and cardiopulmonary bypass support is needed until a new transplanted lung is implanted. Its principle is that venous blood in the body is pumped out of the body, oxygenated by artificial cardiopulmonary bypass made of special materials, and injected into the artery or venous system of patients to play the role of cardiopulmonary replacement and maintain the oxygenated blood supply of human organs and tissues.

Subsequently, the doctor first opened Chen Ting's left chest, removed the original left lung and implanted it into the donor's left lung. At this time, the right lung relies on 100% pure oxygen to maintain systemic blood circulation and air circulation. After 1 hour, bronchus, pulmonary vein and pulmonary artery were anastomosed one after another. When the vascular clamp clamped on the left pulmonary artery was loosened, blood suddenly poured into the new left lung, and the left lung suddenly turned from pale to bright red. Then open the right chest, take out the original right lung and implant it into the donor's right lung. At this time, the newly transplanted left lung undertakes all the oxygenation functions of the body, ensuring the smooth progress of the right lung transplantation. After another 1 hour, the right lung transplantation was successfully completed. When the two bronchi, two pulmonary arteries and two left and right atria of the donor lung were sutured in turn, blood suddenly poured into the newly replaced lung, and the pale lung turned rosy instantly and began to work normally, and the blood flow in both lungs was smooth.

At 8: 45 pm, bilateral lung transplantation was successfully completed, ***5 hours. 16 noon 1 1: 54, after 13 hours of mechanical ventilation, Chen Ting successfully removed the machine and extubated! She can breathe freely now. Chen Ting's father said, "The total cost of surgery is about 800,000 yuan."

Explain again:

The special problem of lung transplantation is that the transplanted lung is at risk of infection because it is preserved in ventilated air with bacteria and the cough mechanism is destroyed by transplantation. The survival time of lung transplant recipients 1 year is about 70%. Without transplantation, these patients have no chance of survival. The long-term survival rate of lung transplantation is unknown. The rejection loss rate of transplanted organs seems to be lower than that of transplanted organs. The function recovered well after transplantation: due to high ventilation, most recipients can resume their daily activities.

If there is something wrong with the lungs, then there will be something wrong with the heart. So simple lung transplantation is rare, but heart-lung transplantation is very common. If a heart-lung transplant can be done, a simple operation will cost about 500 thousand, and there must be a suitable donor. Every month after operation, 10 thousand to 8 thousand anti-rejection drugs are used.

Conditions for changing lungs: first, there must be a donor, that is, someone who gives you lungs; Second, there is nothing wrong with the heart.

I hope the above information can help you. I hope to adopt this answer.
