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 combination medication, it is not certain whether the effect of different types of drugs will be good when used together. Doctors can use combinations for patients based on routine and clinical experience, but occasionally a patient with a unique constitution will end up in tragedy.
To rule out extreme cases, what doctors need to do is to know in advance what combinations of drugs 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 the notes and take notes.
"ecmo uses anticoagulation, and crrt basically does not require anticoagulation, unless low-intensity anticoagulation is used in very special circumstances. The specific situation is based on the patient's various indicators." Xie Wanying said.
Similar to ecmo and crrt treatments, anticoagulants need to be used to avoid various types of bleeding or blood clots. Therefore, the use of two machines together requires urgent attention. At present, Xie has provided a basic idea, which eliminates the need to double 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 of his work. Having someone like this can undoubtedly give her some technical confidence.
Director Wang was also relieved. He was thinking about how to discuss this with Dr. Liu next, but he had never tried it himself and had no clue. He didn't know where to start and was worried. Now someone helped him think ahead and solve a major problem between him and Dr. Liu.
"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." Dr. Liu said.
"It's her who has the solution, not me." Boss Zhang immediately clarified to the world. 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 give a simulated demonstration.
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 Senior 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 make preparations and help Brother with the connection. Puncture, catheter placement and interventional surgery are similar."
As she spoke, she introduced the tool usage procedures to the surgeon and other doctors on the spot. It is not difficult to tell which is the femoral vein tube and which is the femoral artery tube. The longer catheter is for the femoral vein. The femoral artery only needs to be inserted about fifteen 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.
