Remove the right atrium of the recipient, leaving only the left atrium, leaving the rest unchanged. This can avoid the disadvantages of having two sinoatrial nodes, and at the same time save the most troublesome left atrium and pulmonary vein anastomosis time.
Dr. Ye Chuanguang soon heard that they might need to adopt a double-caval method or a whole-heart surgery, because if the double-chamber method was used, there was no need to be specially instructed to preserve enough length of the vena cava to facilitate the subsequent anastomosis during the donor-recipient surgery.
Whether such a nine-year-old child will be able to challenge the most difficult whole-heart method will probably have to wait until the donor heart is sent to the first child's operating room and placed in the chest and pericardium of the child to see how it goes.
Finally, now that he knew what surgery they might plan to perform, Dr. Ye Chuanguang said to them: "I will help you trim it as carefully as possible to facilitate your operation. After all, the journey is quite far."
The hospital across the street is willing to take the initiative to help, and Xie Wanying and Shou'er's teachers must be very grateful.
After the donor heart is taken out from the donor's body, the surgeon will do preliminary trimming. Like before, if there are no requirements from the patient, the surgeon will do it himself and will not specifically mention the length of the superior and inferior vena cava of the right atrium.
Knowing that they may need bicaval cava or whole-heart anastomosis, Dr. Ye Chuanguang, who is also a cardiac surgeon and has undergone a heart transplant, knows that the anastomotic ends of the pulmonary veins on both sides of the left atrium are the most difficult to deal with. As a doctor who removes a donor heart,
He can help his colleagues to repair this place in advance: remove all the tissue between the left superior and inferior pulmonary vein group and the right superior and inferior pulmonary vein group on the posterior wall of the left atrium, and turn them into two large cuffs, which are anastomotic with the receptor.
The number of stitching steps is reduced from four to two in one go.
In this way, the matters that need to be coordinated are basically over. After verifying that other conditions are correct, Dr. Duan and Pan will fly to the First Affiliated Hospital of Zhongshan Medical University to pick up the donor heart.
It is estimated that it will take several hours to fly back and forth, so there is no need to rush to send the child to the operating room. Before that, Xie Wanying and Wei can go to the picu to spend some time with little Zhu Xing.
Zhu Xing looked at his brothers and sisters and said, "When will my sister come back?"
After living here in picu for a while, this kid actually has the consciousness to be an older brother. Don’t worry about yourself, worry about the situation of the little sister in the bed next to you first.
Regarding Xiaohui's surgery, Xie Wanying and Wei remembered that they seemed to have heard other doctors mention it when they were in the doctor's office: the donor heart Xiaohui needed was not far from the capital. Dr. Han took the hospital ambulance to the destination hospital and came back.
, it is expected that four hours will be enough. No wonder Xiaohui was pushed into the operating room early to prepare.
According to this timetable, it is speculated that Xiaohui should be under anesthesia now and prepare for a thoracotomy. The specific time for the thoracotomy to start will be after Dr. Han confirms that the donor heart is obtained at the hospital where the donor is located.
The operation cannot be started too early. Too long operation time will be harmful to the child. More importantly, there is a fear of variables when taking the donor heart. For example, Dr. Han went there and found that the donor heart was not consistent with the previous report.
If the patient is not suitable for you, you can only reject it. The probability of this variable is very low, but no one can say for sure until you get the thing.
Later you will find that the size of the donor heart is by no means the most feared thing in organ transplantation.
After little Zhu Xing fell asleep, Xie Wanying and Wei Shangquan walked out of the picu.
