Iatrogenic pneumothorax: experience of a Moroccan Emergency Center

Abstract The incidence of iatrogenic pneumothorax (IPx) will increase with invasive procedures particularly at training hospitals, which is why we have made a retrospective study of the common diagnostic or therapeutic causes of IPx and its impact on morbidity. From January 2011 to December 2012, 36 patients developed IPx as emergencies, after an invasive procedure .Their mean age was 38 years (range: 19-69 years). Of the patients, 21 (58%) were male and 15 (42%) were female. The purpose was diagnostic in 6 cases and therapeutic in 30 cases. In 8 patients (22%) the procedure was performed due to underlying lung diseases and in 28 patients (78%) for other diseases. The procedure most frequently causing IPnx was central venous catheterization, with 20 patients (55%), other frequent causes were mechanical ventilation, 8 cases (22%) of whom we reported 3 cases of bilateral pneumothorax, 6 cases of thoracentesis (16%) and 2 patients had life-saving percutaneous tracheotomy. The majority of our patients were managed by a small chest tube placement (unilateral n = 30, bilateral n = 3).The average duration of drainage was 3 days (range: 1-15 days), sadly one of our patients died of ischemic brain damage 15 days after tracheotomy. At training hospitals the incidence of IPnx will increase with the increase in invasive procedures, which should only be performed by experienced personnel or under their supervision.
