Remove the right atrium of the recipient, leaving only the left atrium, leaving everything else 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 quickly 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 vena cava length for 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 Shouer 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 make it easier for you to operate. 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 removed from the donor's body, the surgeon will perform preliminary trimming. Like before, if there are no requirements from the patient's side, 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, knew that the anastomotic ends of the pulmonary veins on both sides of the left atrium were the most difficult to deal with. As a doctor who takes the 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, turning it into two large The cuff and the anastomosis end of the receptor suddenly changed from four to two, reducing the number of suturing steps.
In this way, the matters that need to be coordinated are basically completed, and then it is verified that other situations are correct. Just waiting for Dr. Duan and classmate Pan to fly to the First Affiliated Hospital of Zhongshan Medical University to get the donor heart.
I estimate 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 classmate Wei can go to 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 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 a hospital ambulance to the destination hospital and back again, which was expected to take four hours. No wonder Xiaohui was pushed into the operating room early to prepare.
According to this time schedule, Xiaohui should be under anesthesia and ready to open her chest. The specific start time of the thoracotomy should wait until Dr. Han confirms that the donor heart has been obtained at the hospital where the donor is located.
The operation cannot be started too early, as long operation time will be harmful to the child. What's more important is the fear of variables when taking the offering heart. For example, when Dr. Han went there and found that the donor heart was not consistent with the previous report and was not suitable for his patient, he had no choice but to reject it. The probability of this variable is very low, but no one can tell before getting 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.
