Insertion of double-lumen tubes (DLTs) (Mallinckrodt) is challenging and is carried out in lung, chest wall, mediastinal, and spine surgeries. DLTs are generally inserted for lung isolation and one lung ventilation in thoracic surgery. It is particularly employed for lung cancer surgeries (pneumonectomies). The indications for insertion of left- and right-sided DLTs are distinct and defined. There have been several instances of misplacement  of DLT during various stages of thoracic anesthesia. An experienced thoracic anesthesiologist is recommended for successful repositioning of a misplaced DLT. Left-sided DLTs are more commonly placed due to their greater safety margin  as compared to right-sided DLTs. Left-sided DLT can sometimes wrongly enter the right bronchus during placement. Confirmation of its position and tube readjustment is a risky procedure, which must be done under the guidance of a fiber-optic bronchoscope. We hereby present a set of four algorithms for repositioning of a left-sided DLT accidentally misplaced into the right main bronchus. The supplemental use of a direct laryngoscope in addition to fiber-optic bronchoscope during tube readjustment is also highlighted. An experienced thoracic anesthesiologist supported by a second anesthesiologist is recommended for a successful outcome. Care should be taken to ensure adequate patient oxygenation and hemodynamic stability during the repositioning. There is risk of loss of airway, hypoxia, bronchospasm, rupture of DLT cuff, airway trauma, and even dislodgement of fragile cancerous tissue during repositioning. These algorithms may prove helpful in the training of anesthesia residents in thoracic anesthesia. Step-wise following of these four algorithms can ensure a safe and successful tube repositioning, with improved outcomes in all thoracic surgeries, including lung resections [Figure 1], [Figure 2], [Figure 3], [Figure 4].
