After DLT insertion, clinical verification was made by auscultation, then FOB was applied. At lateral decubitus, the position of DLT was rechecked by auscultation, and then by FOB. The incorrect position including malposition and misplacement were compared between two routine methods of auscultation and FOB.Results: After blind intubation, 21.1% of DLTs were considered to be in an incorrect position. Meanwhile, FOB showed that 46.1% of DLTs were not placed correctly. Among all the patients, 53.9% of DLTs were in the optimal position. Misplacement was diagnosed in 35.5% and malposition in 10.5% of the patients. After positioning to the lateral decubitus, using auscultation, we found that 5.3% of tubes were dislocated, but according to FOB, it was 10.5%. The agreement coefficient between auscultation and FOB was 0.42 in the supine position and 0.64 in lateral position.Conclusion: Our results showed that although FOB needs more time to check the position of DLT, it should be used to confirm the exact position of DLT. %U http://www.jimc.ir/article_151499_66e636c37c74ea51a297167eab690f5e.pdf
