    Okay, now I have chosen the most difficult technique to perform, but there is not much time left for the surgeon and assistant.  The numbers on the electronic clock on the wall jumped to five hours and thirty-two minutes.

    The air in the operating room became scorching hot, and the doctors¡¯ faces became sticky with sweat behind their masks.  I only heard 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, right?"

    "Yes. Fortunately, I can use it in time."

    "Whether it can be used may have to wait until the heart arrives. How is the surgery going on Dr. Cao's side?"

    "It's hard to say. Their donor hearts were far away, and it took a long time to get them back. The heart was least wanted for a long time. Maybe the two operations ended at about the same time."

    ¡°Tonight¡¯s two surgeries both used unusual donor hearts and challenged the technical limits of transplant doctors.

    "It's almost over? Both surgeries should be atrioventricular anastomosis."

    "No. Dr. Cao said he wanted to transplant his whole heart."

    ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ¡ª¡ªThis should be the almost unanimous voice of those who heard the answer.

    Someone ran to the door of Cao Zhao's operating room and poked his head around, trying to find out how the other party planned to complete this difficult operation.

    ???????????????????????????????????????????

    If a surgeon has magic, it is expected to be like the magic revealed by Xie Wanying in pediatric orthopedics. It will be a complete set of surgical techniques with theory and practice.  Specifically, when it comes to surgery, the doctor's handwork must be integrated with the instruments in his hand to achieve superb results.  This is the warning that Xie received from Teacher Tan early in the morning.

    Speaking of which, after practicing for so long, the instructors I have followed each have their own martial arts secrets for the equipment and magic weapons they hold.  For example, suturing is the most basic surgical technique. The materials each instructor chooses are closely related to his or her specialty. The skills he has learned become like eight immortals showing off their magical powers across the sea, and they cannot be the same.

    In pediatric cardiac surgery, we just mentioned that the anastomotic suture is extremely difficult.  How can doctors solve this problem?

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

    Let¡¯s talk about the suture material first. If no special equipment such as a stapler is used, the doctor will sew by hand stitch by stitch. The focus of attention is on the suture line.  The anastomotic sutures for heart transplantation can only be sewn manually by doctors.  The anastomosis angle of each blood vessel in this place is too tricky, and the flexibility of the suturing operation is too high. The rigid stapler cannot meet these harsh conditions.

    How to choose sutures?  Let¡¯s talk about the diameter of the suture first. The thickness of the suture is represented by several zeros. The line with six zeros is the thinnest.  An interesting point to mention here is that the suture marks have the same number, but the thickness of different materials is different. Some materials may have six zeros thicker than another six zeros material.  These all need to be explored by the surgeon himself.

    OK, the surgeon made a sound: six zero lines.

    It¡¯s no surprise that the thinnest and small ones in pediatrics can be used securely with the thinnest thread.

    What material is used for the thread?

    The skilled instrument nurse does not need to be reminded by the surgeon, and first threads a polypropylene thread.  This is an excellent non-absorbable suture commonly used in surgery.

    As soon as you hear that the sutures are non-absorbable, some patients may become agitated and question whether the doctor is seeing bad sutures that the patient has no money to use.
