RESUMEN

BACKGROUND: The effectiveness of prophylactic continuous positive pressure ventilation (CPAP) after thoracic surgery is not clearly established. OBJECTIVE: The aim of this study was to assess the effectiveness of CPAP immediately after lung resection either by thoracotomy or thoracoscopy in preventing atelectasis and pneumonia. DESIGN: A multicentre, randomised, controlled, open-label trial. SETTINGS: Four large University hospitals at Madrid (Spain) from March 2014 to December 2016. PATIENTS: Immunocompetent patients scheduled for lung resection, without previous diagnosis of sleep-apnoea syndrome or severe bullous emphysema. Four hundred and sixty-four patients were assessed, 426 were randomised and 422 were finally analysed. INTERVENTION: Six hours of continuous CPAP through a Boussignac system versus standard care. MAIN OUTCOME MEASURES: Primary outcome: incidence of the composite endpoint 'atelectasis + pneumonia'. Secondary outcome: incidence of the composite endpoint 'persistent air leak + pneumothorax'. RESULTS: The primary outcome occurred in 35 patients (17%) of the CPAP group and in 58 (27%) of the control group [adjusted relative risk (ARR) 0.53, 95% CI 0.30 to 0.93]. The secondary outcome occurred in 33 patients (16%) of the CPAP group and in 29 (14%) of the control group [ARR 0.92, 95% CI 0.51 to 1.65]. CONCLUSION: Prophylactic CPAP decreased the incidence of the composite endpoint 'postoperative atelectasis + pneumonia' without increasing the incidence of the endpoint 'postoperative persistent air leaks + pneumothorax'.
