Looking at the actual machine, this artificial heart and lung machine seems to be a few large bottles in a string together, with a power device like a water pump, which can pump liquids around. It is a high-end medical machine, and it must be connected to a computer and a computer.
The display can monitor various operating parameters and data.
The artificial heart and lung machine is a little larger, with several drainage tubes and blood reservoirs, which can help doctors fully drain blood from the patient's left atrium during surgery. Without this thing, EMCO will increase the left heart pressure and expand the left ventricle.
Such a problem arises.
EMCO also has its advantages. It is a one-way closed cycle with fewer drainage tubes, which can reduce the contact between gas and blood. Since heparin must be used for extracorporeal circulation, the amount of heparin is guided by the activation of coagulation time ACT. EMCO ratio
The ACT required by artificial cardiopulmonary machine is short and the amount of heparin is small. It is safer if it is not used during the operation as a rescue for critically ill patients.
Now in surgical operations, artificial heart and lung machines are used. For artificial heart and lung machines, there are bubble oxygenators and membrane oxygenators. The membrane oxygenator was invented late, and compared with bubbles, it is less harmful to blood.
The overall effect is much better than that of bubble oxygenators. In some hospitals, the bubbles purchased in the early years cannot be thrown away and can be used. There are not many new membrane-type machines that are not enough for patients to use. In the end, it must be
The number of cases used in patients at this stage is higher. You can only wait until the backward machines are gradually eliminated. This process is the same as factory updates equipment, and there is a process.
Guozhi is considered relatively good, and the membrane type is more than the bubble type. Today, the patients use membrane type in the operation.
When the teacher was doing it, Xie Wanying was learning to observe. Teacher Pang occasionally said a few words. As a clinical teacher, he might say a few words, but every sentence is the key point and needs to be engraved in his heart.
According to Teacher Pang, patients should first undergo general anesthesia. During this anesthesia process, it can be seen that the anesthesiologist inserted an esophageal ultrasound probe into the patient. It can be seen that Guozhi, a specialized hospital, seems to be applying an esophageal ultrasound probe to an exocardial thoracoscope to an exoscopic thoracoscope.
A little attempt was made during the operation.
In the control room, a group of cardiovascular people from the National Association of China looked at this scene and thought that their department was still using this thing to assist in surgery. The reason why Fu Xinheng quickly accepted Xie's opinion that time was because the esophageal ultrasound was used in surgical operations.
There have been literature reports in the Chinese medical community, but it is an attempt to not be promoted on a large scale. If domestic doctors want to use it, they must take it step by step before large-scale applications. Starting from ordinary cases, be cautious and you will not make mistakes.
.
Furthermore, where did Xie use it? It was used for non-cardiac surgery. No foreign literature has reported such a thing. Therefore, it was shocked by all the surgeons at the exchange meeting at that time.
It seemed that he was remembering this incident, and Zhang Huayao's fingers were pinching his chin again. On the day of the exchange meeting, he secretly came to the scene after receiving the news. When he arrived, he happened to see the operation scene that surprised everyone. For this reason, he looked at it.
With the old mother, Teacher Lu, who was very surprised, she was also deeply surprised.
When did any doctor in China make the surgery so avant-garde? As a cardiac surgery master, he understands the situation of using this thing in surgery better than others.
