According to statistics, the incidence of aortic coarctation is about three out of 100,000, and the proportion of Rh-negative blood (commonly known as “panda blood”) in Han Chinese is about one in a thousand, and this three-out-of-a-million chance thing came to an old man in Deqing, Zhejiang. Fortunately, after the hospital’s cardiothoracic surgery team, Zhejiang Province central blood station and other cooperation, the old man was able to come back from the dead. Last December 30 at about 5:00 pm, 64-year-old Luo old man in the chopping wood suddenly felt a sharp pain in the chest and back tear-like, family members rushed him to the local hospital. After initial treatment and examination, doctors at the local hospital suspected that he was suffering from an extremely dangerous and fatal disease: acute aortic coarctation (type A). The mortality rate of this disease increases by 1% every hour that passes, and Luo was rushed to Zhejiang Provincial People’s Hospital. The emergency room of Zhejiang Provincial People’s Hospital notified Cui Yong, deputy director of thoracic surgery, as soon as Luo’s condition was confirmed. Cui Yong, who then arrived at the hospital, realized that this was a very dangerous sign and the hospital immediately started an emergency channel for aortic coarctation. This is one of the largest surgeries a person can undergo under current medical conditions, and requires a team of about 10 people to complete. The principle of the operation is like needing to replace a water supply line, which can only be done by turning off the pump, and in the human body, the doctor needs to drop the patient’s body temperature below 25°C and stop the blood circulation throughout the body in order to replace the broken blood vessel and save the patient’s life in the limited time available. When the operation was ready, another problem was in front of the doctor: Luo Lao-Be was type A Rh-negative blood! Cui Yong immediately contacted Chen Bingyu, director of the hospital’s blood transfusion department, who immediately asked the Zhejiang Provincial Blood Center for help. Zhejiang central blood station emergency use of 1,200 ml of frozen red blood cells, blood station staff and overnight notification of the “panda blood” blood type rushed to donate 800 ml, to solve the urgent need. Eventually the critical condition of the old man was sent to the operating room, his heart stopped beating when the chest cavity was opened. All the conditions were ready at that moment, and the doctors immediately started the extracorporeal circulation, and the patient was safe. Luo’s surgery lasted 6 and a half hours and was completed successfully. He was taken off the ventilator on the fourth day after surgery and transferred out of the intensive care unit on the fifth day. Recalling the scene, Cui Yong exclaimed, “It was really very, very lucky. In a case like Lao Luo’s, even if we wasted 10 more minutes, we might not have been able to return.”
