n/a: not available, data was not made available in the paper. : complications definition includes persistent air leak more than 7 days or bleeding requiring a blood transfusion. : complications related to surgery included postoperative air leak, pneumothorax, subcutaneous emphysema, bleeding, and wound infection. : persistent air leak through chest tube postoperatively, postoperative pneumothorax, postoperative hemorrhage (>500 mL blood loss in first 24 h), postoperative myocardial infarction, intraoperative desaturation (oxygen saturation, 90% or PaO2, 60 mmHg) and persistent air leak postoperatively, intraoperative hypotension (>20% reduction in blood pressure), and postoperative pneumothorax. : prolonged air leak (>4 days) and massive subcutaneous emphysema. : air leaks (leaky chest tubes without pneumothorax, pneumothoraces requiring chest tubes, subcutaneous emphysema without pneumothorax, and bronchopleural fistula after chest tube removal) and bleeding. : required blood transfusion during the 48 hr period following OLB, for a hemothorax, mechanical complication beginning during the 48 hr period following OLB pneumothoraces, and moderate air leaks from operative chest tubes for 24 hrs that did not require surgery. : persistent air leak (longest air leak lasted 14 days), bronchopleural fistula, and patients requiring reintubation with prolonged mechanical ventilation. ∧∧: includes interstitial pneumonitis, interstitial fibrosis, Pneumocystis carinii, bronchiolitis obliterans, lung carcinoma, metastatic carcinoma, infectious and other pathological diagnosis on lung biopsy. : prolonged air leak requiring prolonged chest tube drainage but no surgical therapy. μ: persistent air leak, bronchopleural fistula, empyema, and wound infection. : added or dose changed. |
