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 it must be connected to a computer and computer.
The display monitors 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 blood from the patient's left atrium during surgery. EMCO does not have this feature, which will cause the patient's left heart pressure to increase and the left ventricle to expand.
Such problems arise.
EMCO also has its advantages. It is a one-way closed circulation with fewer drainage tubes, which can reduce the contact between gas and blood. Since extracorporeal circulation must use heparin, the amount of heparin used is guided by the activated coagulation time ACT. EMCO is better than
The artificial heart-lung machine requires a short ACT and a small amount of heparin. It is safer if it is not used during surgery to rescue critically ill patients.
Nowadays, artificial heart-lung machines are used in surgical operations. Artificial heart-lung machines include bubbling oxygenators and membrane oxygenators. Membrane oxygenators were invented late and cause less damage to blood than the bubbling type.
The overall use effect is much better than that of bubble oxygenators. In some hospitals, the bubble oxygenators purchased in the early years can be used without throwing them away. There are not many newly purchased membrane oxygenators for patients. In the end, it will definitely be
The bubble type has been used on more patients at this stage. We can only wait for the gradual elimination of outdated machines. This process is the same as updating equipment in factories, and it requires a process.
Guozhi is considered to be better, with more membrane machines than bubble machines. The patient used the membrane machine during the surgery today.
While the teacher was operating, Xie Wanying was studying and observing. Teacher Pang occasionally spoke a few sentences. As a clinical teacher, she may speak less, but each sentence is the key point and needs to be engraved in the hearts of the 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 applied the esophageal ultrasound probe in extracardiac thoracoscopy.
There was a little bit of experimentation during the surgery.
In the control room, a group of cardiovascular people from the National Association of China looked at this scene and thought that their own department was still using this thing to assist in surgery. The reason why Fu Xinheng quickly accepted Xie's opinion that time was because esophageal ultrasound is used in surgical operations.
There have been literature reports in the Chinese and foreign medical circles, but they are attempts and have not been promoted on a large scale. If domestic doctors want to use it, they must take it step by step before applying it on a large scale. Start with ordinary cases, and there is nothing wrong with being cautious.
.
Furthermore, where did Mr. Xie use it? It was 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 at that time.
As if remembering this incident, Zhang Huayao pinched his chin with his fingers again. On the day of the exchange meeting, he sneaked in after receiving the news, and when he arrived, he happened to see the surgery scene that amazed everyone. For this reason, he hoped
Looking at the surprised expression of my old mother, Teacher Lu, I 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 could Xie use it outside the liver and gallbladder? It is simply strange.
