[Needle exsufflation could be the first line treatment of complete primary spontaneous pneumothorax at emergency room].

Primary spontaneous pneumothorax (PSP) is associated with a low attributable morbidity-mortality because of absence of acute respiratory consequences in young and health subjects with normal baseline respiratory functions. In opposite, intercostal tube drainages, first-line surgical drainage or chemical pleurodesis are associated around 5% of complications or adverse effects. Guidelines were controversial, primary exsufflation becomes recommended, from now on.
