A Randomized Controlled Study of the Use of Video Double-Lumen Endobronchial Tubes Versus Double-Lumen Endobronchial Tubes in Thoracic Surgery

A Randomized Controlled Trial Comparing Novel Triple-Cuffed Double-Lumen Endobronchial Tubes with Conventional Double-Lumen Endobronchial Tubes for Lung Isolation

“…The results of the present study suggest that lung isolation by using ANKOR DLT can be accomplished regardless of using FOB. Using ANKOR DLTs can reduce the need for multiple attempts of DLT placement for lung isolation, which entails inevitable risks of airway trauma, hypoxemia, and hypercapnia, particularly when non-thoracic anesthesiologists or trainees are conducting the procedure [19]. It is also notable that given this feature of ANKOR DLT, their use may be considered in situations in which FOB is not feasible, such as in cases of massive pulmonary secretion or bleeding.…”

“…In a previous case report, an ANKOR DLT was successfully placed to perform lung isolation in a lung transplant patient who exhibited massive secretion due to idiopathic pulmonary fibrosis [8]. Furthermore, given that there are substantial costs associated with the use, maintenance, and repair of FOB equipment, the use of ANKOR DLT may have some cost/benefit advantages with respect to reducing the use of FOB resources in developing countries or small-volume institutions [19]. Taken together, the advantage of using ANKOR DLT is that the accuracy can be increased in positioning the DLT by simply adding the carinal cuff located at a point between the distal opening of the tracheal lumen and the proximal margin of the bronchial cuff.…”

Dimensional Variations of Left-Sided Double-Lumen Endobronchial Tubes

“…In clinical practice, anesthetists or intensivists have learnt to live with these limitations for years, even though the problems associated with the use of (inappropriate) DLTs are considerable. Clayton-Smith et al [8] reported an incidence of airway injuries of close to 30%, and Heir et al [20], in a study, including the VIVASIGHT ® DLT reported a rate of DLT dislodgement during positioning in almost 2/3 and during surgery in almost 1/3 of their studied patients, respectively. Nevertheless, there is little to no access to the critical DLT dimensions (i.e., by package insert), despite the call for such detail to be more readily available, which was issued over 20 years ago [18].…”
