In many clinical stories, extracorporeal membrane oxygenation puts patients' families in a dilemma, gives them emotional hope and makes people collapse economically. What is more binding is that the national stock of emergency extracorporeal membrane oxygenation is only about 400 (excluding Hong Kong, Macao and Taiwan), and supporting Hubei depends on the coordinated support of the whole country.
By the end of 20 18, 12 and 3 1 year, there were 260 extracorporeal life support centers and about 400 extracorporeal membrane oxygenation devices in China. Even in the United States, where medical technology is extremely developed, the number of hospitals providing extracorporeal membrane oxygenation in 20 19 is only 264, which is almost the same as that in China.
Detailed introduction:
Extracorporeal membrane oxygenation, also known as extracorporeal membrane oxygenation therapeutic instrument, is also referred to as "Yeke membrane", and many doctors also call it "artificial heart-lung machine". Its working principle is to expel venous blood from the body, oxygenate it with a gas exchange device, and then pump it back to the body with a driving pump, so that the heart and lungs can get a full rest.
Support for lung function can effectively improve hypoxemia and avoid oxygen poisoning caused by long-term inhalation of hyperoxia and airway injury caused by mechanical ventilation; For cardiac function, it can increase and maintain cardiac output, improve systemic perfusion, ensure stable circulation, and thus win time for the recovery of cardiopulmonary function.
At present, extracorporeal membrane oxygenation is the core support of severe heart and lung failure, and it is also called the "last straw" of severe patients, and the corresponding treatment is expensive.
