When the machines are used together, it seems like one plus one equals two, the effect is doubled, and it sounds wonderful.
In medicine, there is definitely no such thing as one plus one equals two. On the contrary, one plus one may result in countless variables and even become zero or negative.
To give a simple example, in clinical combination therapy, it is not certain whether different types of drugs will work well together. Doctors can use combinations for patients based on routine and clinical experience, but occasionally a patient has a different constitution, and the result will still be tragic.
Excluding extreme cases, what doctors need to do is to be aware of the shortcomings of certain drug combinations and take preventive measures.
The same principle applies to using two machines together.
Director Wang followed Dr. Liu and expressed his strong opinion: "Yes, yes, I want to know too."
Many people pricked up their ears and listened, obviously this was an important technical point.
Swish, take a note.
"ECMO uses anticoagulation, but CRRT basically does not need anticoagulation, unless low-intensity anticoagulation is used in very special circumstances. The specific situation is judged based on the patient's various indicators." said Xie Wanying.

Like ECMO, CRRT treatment requires the use of anticoagulants, which are also afraid of various bleeding or thrombosis. Therefore, the use of two machines together is an urgent need for attention. At present, Mr. Xie has provided a basic idea, so there is no need to double the anticoagulation.
Doctor Liu breathed a sigh of relief. She could tell that Teacher Xie was a real talent, and that what he said were all the key points of the work. Having someone like her would undoubtedly give her some technical confidence.
Director Wang also breathed a sigh of relief. He had been thinking about how to discuss this with Dr. Liu, but he had never tried it before and had no idea where to start. Now someone has helped him think ahead and solved a big problem for him and Dr. Liu.
"Teacher Liu's other concern should be how to connect the two machines without any problems," said Xie Wanying.
"Yes. Director Zhang said on the phone that there is a way." said Doctor Liu.
"She has the solution, not me." Boss Zhang immediately clarified it to the world. If you have any questions, please ask Teacher Xie again.
She had given a brief introduction to this point to Mr. Zhang before, so she only needed to explain it to the nephrology teacher in person and demonstrate it in a simulation.
After resolving the two most worrying issues in Dr. Liu's mind, Xie Wanying put on her surgical gown and stood on the other side of the bed to assist Senior Brother Shen.
The machine comes with a large box. When you open it, you can see a series of medical tools that come with the machine, such as puncture needles and puncture cannulas.
Most of the medical staff on the scene had never seen or used these things, including Shen Youhuan, and they were a little confused, so they had to ask the junior sister to help them.
The technique for puncturing the femoral vein and artery is essentially the same.
Xie Wanying gave Brother Shen confidence and said, "I will do the preparation and help you with the connection. Puncture and catheterization are similar to interventional surgery."
As she spoke, she introduced the procedure for using the tools to the surgeon and other doctors. It was not difficult to tell which was the femoral vein and which was the femoral artery. The longer catheter was for the femoral vein. The femoral artery only needed to be inserted about 15 centimeters.
The puncture tools should be similar in appearance and usage.
The operation steps are roughly as follows: After the puncture needle enters the accurate position in the blood vessel, insert the guide wire, withdraw the puncture needle, puncture the subclavian vein, and use a scalpel to expand the skin.
