    Looking at the actual machine, this artificial heart-lung machine seems to be several large bottles strung together, with a power device like a water pump inside, which can pump liquid back and forth.  It is a high-end medical machine and must be connected to a computer and display screen to monitor various operating parameters and data.

    The artificial heart-lung machine is larger and has several more drainage tubes and blood reservoirs, which can help doctors fully drain the blood from the patient's left atrium during surgery.  emco does not have this thing, which will cause problems such as increased left heart pressure and left ventricular expansion in patients.

    emco also has its advantages. It has a one-way closed circulation and fewer drainage tubes, which can reduce the contact between gas and blood.  Since heparin must be used in extracorporeal circulation, the amount of heparin used is guided by the activated coagulation time act.  The emco requires a shorter act than an artificial heart-lung machine and uses less heparin. It is safer if it is not used during surgery to rescue critical and severe patients.

    Now in surgical operations, artificial heart-lung machines are used.  Artificial heart-lung machines include bubble oxygenators and membrane oxygenators.  Membrane oxygenator was invented late. Compared with bubble oxygenator, it causes less damage to blood, and the overall effect is much better than bubble oxygenator.  In some hospitals, the bubble-type ones purchased in the early years can be used even if they are not thrown away.  There are not enough newly purchased membrane-type machines for patients.  In the end, the bubbling method will definitely be used on more patients at this stage.  We can only wait for the gradual elimination of backward machines.  This process is the same as updating equipment in a factory and requires a process.

    Guozhi is considered to be better, with more membrane machines than bubble machines.  Today, the patient uses the membrane type during surgery.

    While the teacher was operating, Xie Wanying was studying and observing.  Teacher Pang occasionally speaks a few sentences. As a clinical teacher, he may speak less, but each sentence is the key point, which needs to be engraved in the hearts of students.

    According to Teacher Pang, the patient must first undergo one-lung ventilation under general anesthesia.  During this anesthesia process, you can see the anesthesiologist inserting an esophageal ultrasound probe into the patient.  It can be seen that Guozhi, a specialized hospital, seems to have made some attempts to apply esophageal ultrasound probes in extracardiac thoracoscopic surgery.

    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 application of esophageal ultrasound in surgical operations has been reported in the Chinese and foreign medical circles, but it was an attempt and has not been widely promoted.  If domestic doctors want to use it, they must take it step by step before applying it on a large scale. Starting from ordinary cases, it will not go wrong to be cautious.

    ¡°Moreover, where is Xie using it?  Used in non-cardiac surgery, such a thing has not been reported in foreign literature.  Therefore, it shocked all the surgeons at the exchange meeting.

    Seemingly remembering this incident, Zhang Huayao pinched his chin with his fingers again.  On the day of the exchange meeting, he arrived secretly after receiving the news. When he arrived, he happened to see the surgery scene that amazed everyone.  For this reason, he looked at the surprised expression of his old mother, Teacher Lu, and he was also deeply surprised.

    When did a doctor in China achieve such an avant-garde approach to surgery?  As a leader in cardiac surgery, he understands the use of this thing in surgery better than anyone else.

    At present, esophageal ultrasound is only used outside the heart in surgical operations. How can Xie use it outside the liver and gallbladder? It is simply strange.
