DOUBLE LUMEN TUBE TRIAL

After passing through the glottis and 90° counterclockwise rotation, the DLT is advanced into the LMB either blindly or by fiberoptic bronchoscopic (FOB) guidance.

DOUBLE LUMEN TUBE TRIAL

Trial registrationĬ Identifier: NCT01371773.įor one-lung anesthesia during thoracic surgery, a left-sided double-lumen endobronchial tube (DLT) is preferred over a right-sided DLT because of its greater margin of safety for correct positioning in the left mainstem bronchus (LMB). Moreover, we were usually able to reposition the misplaced DLTs into the left bronchus by using the blind techniques. Smaller left-sided DLTs were more frequently misplaced into the right mainstem bronchus than larger DLTs.

In 40 of the 48 (83.3 %) patients, blind repositioning was successful. All of these factors were significantly inter-correlated each other ( P < 0.001). DLT misplacements occurred more frequently in females, in patients of short stature or with narrow trachea and bronchi, and when small-sized DLTs were used. ResultsĭLTs were inadvertently advanced into the right bronchus in 48 of 1135 (4.2 %) patients. Moreover, when DLTs were misplaced into the right bronchus, the bronchial tube was withdrawn into the trachea and blindly readvanced without rotation, or with 90° or 180° counterclockwise rotation while the patient’s head was turned right. Patients’ clinical and anatomical characteristics were analyzed to investigate risk factors for DLT misplacements with logistic regression analysis. This was an observational cohort study performed on the data depository consecutively collected from patients who underwent intubation of left-sided DLTs for 2 years.

Therefore, incidence, risk factors, and blind repositioning techniques for right bronchial misplacement of left-sided DLTs were investigated. However, blind advancement may result in misplacement of left-sided DLTs into the right bronchus. Double-lumen endobronchial tubes (DLTs) are commonly advanced into the mainstem bronchus either blindly or by fiberoptic bronchoscopic guidance.
