SEPARATION
Dealing with patients who have a difficult airway and require lung separation remains a challenging task for anaesthesiologists. Moreover, using a double lumen tube (DLT) for lung separation is more difficult compared to the use of a single lumen tube (SLT) due to the length, width, and other noncompliant characteristics of DLTWith the development of a silicone DLT (HumanBroncho, Therefore, we evaluated the intubation performance of silicone DLT and polyvinyl chloride SLT with fiberoptic bronchoscope in patients who reproduced a difficult airway with a semi-rigid neck collar.
