Single lung ventilation (SLV) with the double lumen tube (DLT) has been an effective process for providing surgical exposure in the thoracic cavity and has been applied effectively in the operating room. SLV also aids in protecting a healthy lung from the ill effects of fluid from an unhealthy lung, which may be blood, lavage fluid, or malignant or purulent secretions. Ensure correct placement, which is required and confirmed by a fiberoptic bronchoscope (FOB).The use of the DLT has been proven to be effective, but it has its challenges and drawbacks. This article proposes an alternative technique to the DLT in SLV without the use of a FOB. We have implemented this technique in 14 cases, however, we would like to discuss two challenging cases that have highlighted the advantages of this new technique.
