Re-expansion Pulmonary Edema after Chest Drainage for Pneumothorax; Evaluation of Risk Factors in 630 Episodes

2021 ARC Journal of Surgery  
Re-expansion pulmonary edema (RPE) is a rare complication after chest drainage of spontaneous pneumothoraxs. We report RPE cases in our hospital over 5 years. Methods : Clinical records of patients treated for spontaneous pneumothorax from April 2012 to March 2019 at our institute were retrospectively reviewed. Chest tube placement was performed 630 times. RPE is diagnosed by chest x-ray or chest computed tomography within 24 to 48 hours after drainage. Patients were categorized into RPE and

Forty cases of 45 were 3rd degrees in lung collapse classification and 11 cases showed total lung collapse. Oxygen was administered in 15 cases. Thirteen cases presented with dyspnea after intense cough. Periods from onset to drainage, cough and aterectasis or lung collapse classification are significantly difference between RPE and non-RPE groups on univariate analysis and multivariate analysis Conclusions: Large pneumothorax or total lung collapse of greater than 4 days of duration is associated with RPE development in the presence of intense cough. Management of cough after pneumothorax treatment may be a potential therapy to prevent RPE. Abbreviations: RPE, Re-expansion pulmonary edema
