When the machines are used together, it's like one plus one equals two, the effect is doubled, and it sounds wonderful.
There is certainly no good thing like one plus one equals two in medicine. On the contrary, one plus one may have countless variables and even become zero or negative.
To give a simple analogy, in clinical drug combination, it is not certain whether the effect of different types of drugs will be good when combined. Doctors can use combinations for patients based on routine and clinical experience, but occasionally a patient with a unique constitution will still end up in a tragedy.
end.
To rule out extreme cases, what doctors need to do is to know in advance what combinations of medications will have their drawbacks and take preventive measures.
The same principle applies when two machines are used together.
Director Wang followed Dr. Liu and expressed his strong position: "Yes, yes, I want to know too."
Many people pricked up their ears and listened. Obviously this is an important technical point.
Oh, take notes and take notes.
"ecmo uses anticoagulation, and crrt basically does not require anticoagulation, unless there are very special circumstances where low-intensity anticoagulation is used. The specific situation is determined based on the patient's various indicators." Xie Wanying said.
As with ECMO and CRRT, anticoagulants need to be used during the course of treatment, and there is also a fear of various bleeding or blood clots. Therefore, the combination of the two machines is an urgent matter. Currently, classmate Xie has provided a basic idea, and there is no need to double the anticoagulation.
Dr. Liu was immediately relieved. She could tell that this teacher Xie was really talented and practical, and what he said were all the key points in his work. Having such a person would undoubtedly give her some technical confidence.
Director Wang was also relieved. He was originally thinking about how to discuss this with Dr. Liu, but he had never tried it himself and had no idea. He didn’t know where to start and was worried. Now someone could help him in advance.
Thinking of solving a big problem between him and Dr. Liu first.
"Teacher Liu's other focus should be on how to connect the two machines without causing problems," Xie Wanying said.
"Yes. Director Zhang said on the phone that there is a way." Doctor Liu said.
"It's her who has the solution, not me." Mr. Zhang immediately clarified to the world that if you have any questions, please ask Teacher Xie again.
She had briefly introduced this to Mr. Zhang before, and she only needed to explain it to the nephrology teacher in person and demonstrate it through simulations.
After resolving the two most anxious questions on Dr. Liu's mind, Xie Wanying put on a surgical gown and stood on the other side of the hospital bed as an assistant to Brother Shen.
There is a large box that comes with the machine. When opened, you can see a series of medical tools that match the machine, such as puncture needles and cannulas.
Most of the medical staff on site had never seen or used these things, including Shen Youhuan, who couldn't help but feel a little confused, so they had to ask the junior sister to help them.
The technique for puncturing the femoral vein and femoral artery is actually the same.
Xie Wanying gave Brother Shen confidence and said: "I will do the preparations and help Brother with the connection. Puncture, catheter placement and interventional surgery are similar."
With that, she introduced the tool usage process to the surgeon and other doctors on the spot. It is not difficult to distinguish which is the femoral vein tube and which is the femoral artery tube. The longer catheter is for the femoral vein. Only fifteen tubes need to be inserted into the femoral artery.
About centimeters.
The same puncture tools should be similar in appearance and usage.
The operation steps are roughly as follows: after the puncture needle enters the exact position inside the blood vessel, insert the guide wire, withdraw the puncture needle, puncture the subclavian vein, and use a scalpel to expand the skin.
