D Health officials in the United States reported last week on what they believe could be a medical first. Officials said doctors performed what could be the first double lung transplant on a person whose lungs were severely damaged from vaping( 吸电子烟 ). The operation reportedly saved the life of a teenager from the state of Michigan. The young man was admitted in early September to a Detroit-area hospital with what appeared to be pneumonia ( 肺炎 ), a common lung infection. The teen was later sent to Children's Hospital of Michigan in Detroit. On October 3, he was transported to Henry Ford Hospital, where the transplant was performed 12 days later. Hassan Nemeh, a surgical doctor at Henry Ford Hospital, told The Associated Press that the damage done to the teenager's lungs from vaping could not be undone. He warned parents to think about that and to tell their children to do so as well. A statement written by the teen’s family said, “We asked Henry Ford doctors to share that the horrific life-threatening effects of vaping are very real”. More than 2,000 Americans who vape have gotten sick since March. Many of them are teenagers and young adults. At least 40 people have died. Recently, the U.S. Centers for Disease Control and Prevention reported a discovery into what might be causing people who vape to become sick. They identified the chemical compound vitamin E acetate( 醋酸盐 ) as “ a very strong culprit ” . Researchers found the chemical compound in fluid taken from the lungs of 29 patients. In other studies, Vitamin E acetate was found in liquid from electronic cigarettes and other vaping devices. Dr. Lisa is a lung specialist and medical director of Henry Ford's Lung Transplant Program. She told The AP, “Vaping-related injuries are all too common these days. Our adolescents are faced with a crisis.” Hassan Nemeh added, “We hope sharing this patient's story prevents anyone else from experiencing a vaping injury that would require a transplant.” 32.
