Well, now we have chosen the most difficult procedure, but the surgeon and his assistant don't have much time left. The numbers on the electronic clock on the wall kept ticking, and it jumped to five hours and thirty-two minutes.
The air in the operating room became scorching hot, and the doctors' faces were sticky with sweat behind their masks. I heard some movement in the operating room next door, and someone passing by in the operating room corridor said, "Is Dr. Han on his way back?"
"Yes. Fortunately, I was able to use it in time."
"Whether it can be used may have to wait until the heart arrives. How is the operation going, Doctor Cao?"
"It's hard to say. Their donor hearts are far away, and it takes a long time to get them back. Hearts are the most unwelcome for a long time. Maybe the two operations ended at about the same time."
Both operations tonight involved unusual donor heart limitations, challenging the transplant surgeons' technical limits.
"Almost finished? Both operations should be atrioventricular anastomosis."
"No. Doctor Cao said this one needs to have the entire heart transplanted in."
Oh my god. — This should be the unanimous cry of those who heard the answer.
...
...
Someone ran to the door of Cao Zhao's operating room and peeked in, trying to find out how the other party was going to complete this difficult operation.
Do you want to learn some magic like a god?
If surgeons have magic, it is expected to be a set of surgical techniques that are complete in theory and practice, just like the magic that Xie Wanying showed in pediatric orthopedics. To be more specific, in surgery, the doctor's handwork must be integrated with the instruments in his hands to achieve a superb effect. This is the warning that Xie received from Teacher Tan early in the morning.
In retrospect, the instructors I have been following for such a long time have their own secrets about the instruments they hold. For example, suturing, the most basic surgical technique, the materials selected by each instructor are closely related to their own specialty, and the skills they have learned are different, and it is impossible for them to be the same.
In pediatric cardiac surgery, we just talked about the difficulty of suturing the anastomosis. How do doctors solve this problem?
There are two basic elements of suturing: one is the suture material, and the other is the suture technique.
Let's talk about suture materials first. If the doctor does not use special instruments such as staplers, he will sew manually one stitch at a time, and the focus is on the suture line. It happens that when suturing the anastomosis of heart transplantation, doctors can only sew manually. The anastomosis angles of the blood vessels in this place are too tricky, and the flexibility of the suturing operation is too high. The rigid stapler cannot meet these demanding conditions.
How to choose sutures? First, let's talk about the diameter of the sutures. The number of zeros on the sutures represents the thickness, and the suture with six zeros is the thinnest. Here is an interesting point. Sutures with the same number on them may have different thicknesses. Some materials with six zeros may be thicker than others. Surgeons need to figure this out by themselves.
Okay, the surgeon made a sound: six zero lines.
Not surprisingly, pediatric devices are all very thin and small, so it is safer to use the thinnest thread.
What material of thread is used?
Without the surgeon's reminder, the skilled instrument nurse first threaded a polypropylene suture, a high-quality non-absorbable suture commonly used in surgical operations.
As soon as they hear that the sutures are non-absorbable, some patients may become very scared and question whether the doctor is using bad sutures because the patients have no money.
