On March 30th, Chinese researchers explored the protection of heart for more than 6 hours of ischemia and the effect of such heart transplantation. The investigators selected 26 cases of cardiac ischemia for more than 6 hours due to objective reasons, reaching (401 ± 43) min. When cutting the heart, quickly reveal the heart, perform effective left and right heart chamber decompression, and then infuse 4°C from the aortic root to improve St. The Thomas solution was 500 ml, and the surface of the heart was washed with ice physiological saline to cool down. After removing the heart, 2000 ml of 4° CUW solution was antegraded from the aortic root and stored in UW solution. For patients with higher pulmonary arterial pressure, intraoperative thioprostone is given and continuous inhalation of nitric oxide to reduce pulmonary artery pressure. Twenty-six patients underwent double-chamber vein anastomosis for orthotopic heart transplantation. The results showed that all 26 patients survived, 21 patients had automatic re-jumping, and 5 patients had re-jump after electric shock. One week after surgery, echocardiography revealed that the size of each chamber of the 26 patients was within the normal range, the pulmonary artery pressure was in the normal range, and the left ventricular ejection fraction was normal. One patient was unable to discontinue cardiopulmonary bypass due to abnormal coronary opening, and the cardiopulmonary bypass was successfully stopped after re-surgery. One patient was unable to stop the ventilator due to cardiac insufficiency and had renal dysfunction, tracheotomy and bedside hemodialysis. Two patients developed I degree atrioventricular block. One patient had a moderate amount of pericardial effusion and was not treated. Therefore, the researchers concluded that under the premise of good myocardial protection from the heart to the transplant, the donor that moderately exceeds the safe storage time can obtain satisfactory short-term effects after transplantation. Even so, it should be advocated. Heart retention time should be within the safe time limit. Meditech Medical Network
