摘要


Background: The choice between a double-lumen tube (DLT) and a bronchial blocker (BB) for lung isolation remains controversial. The aim of this study was to determine if the features of these lung isolation devices affect postoperative pulmonary outcomes. Methods: We retrospectively identified claims by patients who underwent surgery under lung isolation in 2000-2012 in the Taiwan National Health Insurance Research Database. After matching for age, sex, and year of surgery, 1,898 patients were enrolled in a BB group and 5,694 in a DLT group. The risks of readmission in the first postoperative year with pulmonary complications, in-hospital death, and one-year mortality were estimated using conditional logistic regression analysis. Results: Patients in the BB group had higher risks of readmission with pulmonary infection (adjusted odds ratio [aOR], 1.46; 95% confidence interval [CI], 1.22-1.74) or respiratory failure (aOR, 1.38; 95% CI, 1.09-1.76) in the first postoperative year as well as in-hospital death (aOR, 2.03; 95% CI, 1.40-2.94) and one-year mortality (aOR, 1.94; 95% CI, 1.60-2.35) than those in the DLT group after adjustment for the types of the surgeries, hospital accreditation level, underlying comorbidity, and a potentially difficult airway. Patients in the BB group had longer median (interquartile range) stays in the intensive care unit (1 [0-4] vs. 1 [0-3] days, P < 0.001) and in hospital (16 [10-26] vs. 13 [8-22] days, P < 0.001). Conclusion: Patients undergoing thoracic surgery are more likely to experience postoperative pulmonary complications if a BB than a DLT is used.
