Lung transplantation is mainly divided into single-lung transplantation, double-lung transplantation and lobe transplantation. Depending on the type of surgery, the surgical procedures are not the same, but in general, an incision is made to take out the diseased lungs and then do the transplantation of the new lungs, and then the lungs are sutured up and observed at the end. 1. Removal of donor lungs: single-lung transplantation and double-lung transplantation have the same method of removal, usually using a median incision in the sternum, after the donor lungs are removed, they are put into a protective fluid at 4 degrees Celsius. 2. Recipient lung resection: Bilateral lung resection is usually performed by a median sternal incision in the lying position, and single lung resection is performed by a posterior lateral 6th rib incision on the affected side, in which extracorporeal circulation should be established first for bilateral lung resection. 3. Lung implantation anastomosis: unilateral lung implantation anastomosis should be sequentially end-to-end anastomosis of the left atrium and pulmonary artery, and the last needle should be opened to open the atrial clamp and then anastomosed after blood flows out of the pulmonary artery anastomosis. Bilateral lung implantation should be performed under extracorporeal circulation, and the left atrium and pulmonary artery should be anastomosed sequentially after intermittent end-to-end anastomosis of the trachea. 4. Postoperative monitoring: after the end of the operation, the patient needs to be observed in the intensive care unit, and then enter the ward monitoring room after the condition is stabilized. Depending on the patient’s condition, the type of surgery used may be different, and it is recommended that the patient go to a regular hospital in time to listen to the advice of a professional doctor.
