A randomised controlled trial of interventional versus conservative treatment of primary spontaneous pneumothorax

原发性自发性气胸（PSP）是一种肺萎陷，发生在没有潜在肺部疾病的健康人群中。目前的标准治疗方法是将胸腔引流管插入胸腔，排出萎陷肺周围的空气，使肺迅速重新膨胀（“介入治疗”）。我们将决定什么都不做，即让肺部在几周内自行缓慢重新充气（“保守治疗”），对患者来说是否同样好，甚至更好。

Primary spontaneous pneumothorax (PSP) is a collapsed lung that occurs in otherwise healthy people without underlying lung disease. Current standard treatment is to insert a chest drain into the chest to remove the air around the collapsed lung so that the lung re-inflates rapidly ("interventional treatment"). We will determine whether doing nothing, i.e. letting the lung re-inflate slowly on its own over several weeks ("conservative treatment"), is just as good or even better for patients.
