One common problem in preterm babies is respiratory disease. The lungs are the last organs to develop. But a medicine called surfactant can save babies struggling to breathe. The story of this lifesaving medicine begins with a discovery in nineteen fifty-nine by a researcher named Mary Ellen Avery. 早产儿常见的问题之一就是呼吸系统疾病,肺部是最晚发育的器官,但一种名叫表面活性剂的药物可以解救婴儿的呼吸困难。这种救命药的故事始于1959年一位名为玛丽.艾伦.艾弗里的研究员的发现。
