"You stay here. If there is any problem during the operation later and we need to brainstorm, you can help." Dai Ronghong said.
Others didn't expect what she said at all.
The most surprising thing was Doctor 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 underestimate 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. What he was thinking was that he did not dare to underestimate the young people behind him, such as his junior sister.
The operating room is fully staffed. Director Gao serves as an assistant. There are several on-site assistants.
Dr. Che stood at the surgeon's position and first performed peripheral femoral vein puncture and cannulation. This step is not difficult at all for a skilled man who has performed many surgeries and can 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 operation 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 measured electrophysiological picture be accurate.
Xie Wanying followed others to watch in the control room. She saw that Doctor Che's movements were slower than that of Brother Shen, like a slow-motion shot, but he would try his best to reach the point in one step. This is a characteristic of most older doctors, who pay more attention to being steady and in charge.
Through the photograph, you can see the catheters being inserted 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. The atrioventricular bundle catheter is placed on the anterior inner edge of the right atrioventricular orifice. The position here is closest to the atrioventricular bundle and can record the atrioventricular bundle electrogram most clearly and accurately, code-named hbe diagram. The right ventricular catheter is placed at the apex of the right ventricle, code-named rva diagram. The coronary sinus catheter is placed at the mouth of the coronary sinus, code-named 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 the left bundle, you need to penetrate the interatrial septum and discharge 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.
The surgeon places all electrometry catheters as needed for treatment.
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 crucial 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 accurate ablation be achieved.
Seeing this, Xie Wanying remembered the interventional surgery she had done with an acquaintance at a tertiary hospital before she was reborn. She saw with her own eyes that some cases lasted from morning to afternoon, and the surgeon had to give up in the end. On that day, the doctor searched for almost a day and couldn't find the target. I can't analyze where the target is. I can vaguely analyze it based on my experience and it will have no effect after burning it.
This is the most critical technical threshold for this technology.
