"You stay here. If there is any problem during the operation later and we need to brainstorm, you can help." Dai Ronghong said.
Others did not expect what she said at all.
The most surprising thing was Dr. Che, who immediately asked Dai Ronghong: "Who is she? Is she a colleague of yours in the hospital? She is very young."
Being very young is the focus of suspicion.
Dai Ronghong thought of the pitfalls she had fallen into, and said earnestly to Dr. Che: "Don't underestimate some young people today."
"Young people, I know, are becoming more and more powerful. How can I dare to look down on them?" Dr. Che said, clearly looking at the young doctors from the rival Guozhi Hospital.
Shen Youhuan glanced at the other party's star doctor, Dr. Cha, who was also considered a senior doctor, and shrugged his shoulders, thinking that he did not dare to underestimate the young people behind him, such as his junior sister.
Everyone in the operating room is ready. Director Gao is the assistant. There are several on-site assistants.
Dr. Che stood in the position of the surgeon and first performed a peripheral femoral vein puncture and cannulation. This step was not difficult at all for a skilled man who had performed many surgeries and could be completed within a few minutes.
The next thing that makes this surgery different from other interventional surgeries is that various test catheters need to be placed into the inner cavity of the heart.
The doctor in charge of the surgery pedals, adjusts the angle of the operating table and the C-arm of the machine, and makes various perspective cross-sections to ensure that the electrodes of each catheter are accurately placed at the designated position in the heart. Only when the position is accurate can the measurement
The electrophysiological diagram can be accurate.
Xie Wanying followed others to watch in the control room. Dr. Che's movements were slower than that of Brother Shen, like a slow-motion shot, but she would try her best to get to the point in one step. This is a characteristic of most older doctors, who pay more attention to being steady and taking the lead.
.
By taking pictures, you can see that the catheters are placed into the heart chambers one by one. Specifically, the right atrial catheter is placed in the upper part of the right atrium, and the recorded electrogram is displayed on the electrophysiology software analysis screen, code-named hra diagram. Atrioventricular
The bundle catheter is placed on the anterior inner edge of the right atrioventricular orifice, which is closest to the atrioventricular bundle and can most clearly and accurately record the atrioventricular bundle electrogram, code-named hbe diagram. The right ventricular catheter is placed on the apex of the right ventricle.
Now, the code is rva picture. The coronary sinus catheter is placed at the mouth of the coronary sinus, code is cs picture.
The above-mentioned catheter is placed through the right atrium to mainly solve the problem of right bundle disease of cardiac conduction. If you want to solve the problem of left bundle, you need to penetrate the interatrial septum and place the electrode to the left atrium.
Student Wei’s previous electrocardiogram showed that the problem was mainly the right bundle, and there was no need to go to the left bundle for the time being.
According to treatment needs, the surgeon places all electrometry catheters.
The electrophysiological chart data of each catheter was displayed on the screen of the instrument. The rows of white lines on a blue background were spectacular.
The surgeon looked at various graphs and analyzed the data.
As mentioned before, electrophysiological analysis is a very important step. It is to find the patient’s lesions and is directly related to the effectiveness of treatment. Only when this foundation is found, can the next step of ablation be achieved accurately.
Seeing this, Xie Wanying remembered the interventional surgery she had done with an acquaintance at a tertiary hospital before she was reincarnated. She saw with her own eyes that some cases lasted from morning to afternoon, and finally the surgeon had to give up. On that day, the doctor searched for almost a whole day and could not find the target. Analysis
If you don't know where the target is, you can rely on your experience to vaguely analyze it and then burn it to no avail.
This is the most critical technical threshold for this technology.
