  The air in the operating room became scorching hot, and the faces of the doctors behind the masks were a little sticky and sweaty. I only heard the movement in the operating room next door. People passing by in the corridor of the operating room were saying, "Dr. Han is on his way back, isn't he?"

   "Yes. Fortunately, I was able to use it in time."

   "Can we wait until the heart arrives. How is the operation on Dr. Cao's side?"

   "It's hard to say. They donated hearts from a long distance, and it took a long time to get them back. The hearts are the least expected for a long time. Maybe the two operations will end at about the same time."

  Tonight's two surgeries are all about the unusual heart donation limit, challenging the technical limit of the transplant doctor.

   "It's almost over? The two surgeries should be anastomosis."

   "No. Dr. Cao said he wanted to transplant it with all his heart."

   OMG. ——This should be the almost unanimous voice of the people who heard the answer.

  Someone ran to the door of Cao Zhao's operating room to probe his brain, trying to find out how the other side was going to complete this difficult operation.

   Do you do magic like a fairy?

   If a surgeon has an immortal technique, it is expected to be a complete set of surgical techniques with theory and practice, just like the magic revealed by Xie Wanying in the pediatric orthopedics department. To put it into surgery specifically, the doctor's handwork must be integrated with the instruments in his hand to achieve superb results. This is the warning Xie got from Teacher Tan early in the morning.

   Having said that, several instructors who have been practicing for so long have their own martial arts secrets for the magic weapon they hold. For example, in suture, the most basic surgical technique, the materials selected by each instructor are closely related to the specialty they belong to.

  In Pediatric Cardiac Surgery, I just talked about the super-difficulty of anastomotic sutures. How can doctors solve this difficulty?

The basic elements of   suture are two, one is the suture material, and the other is the suture technique.

   Let’s talk about the suture material first. If special instruments such as staplers are not used, the doctor stitches by hand one by one, and the focus of attention is on the suture. It happened to be sutured on the anastomotic stoma of the heart transplant, which can only be sewed manually by the doctor. The anastomosis angle of each blood vessel in this place is too tricky, and the flexibility of the suture operation is too high. The rigid stapler cannot meet these harsh conditions.

  How to choose the suture? Let’s talk about the diameter of the suture first. The thickness of the suture is represented by several zeros, and the line with six zeros is the thinnest. Here is an interesting point, the number of the suture marks is the same, but the thickness of different materials is not the same, and some materials may be thicker with six zeros than another material with six zeros. These all need to be figured out by the surgeon himself.

   Well, the main knife makes a sound: six zero lines.

  No surprise, all kinds of pediatrics are thin and small, and it is safe to use the thinnest thread.

  What material thread?

   The skilled instrument nurse does not need to be reminded by the chief surgeon, and first wears a polypropylene thread to come out. This is an excellent non-absorbable suture commonly used in surgical procedures.

   As long as they hear that they are non-absorbable sutures, some patients may change their tone, questioning whether the doctor sees bad sutures that the patient has no money to use.
