abstract = {Background: Direct insertion of a double-lumen endobronchial tube (DLT) over a fibreoptic bronchoscope (FOB) is considered more difficult and traumatic than that of a single-lumen tube (SLT). We hypothesized that time to intubation over an FOB using a silicone left DLT would be non-inferior to that using a polyvinyl chloride (PVC) SLT.
Methods: Eighty patients were enrolled in this open-label, randomized controlled, non-inferiority trial. Patients were randomly allocated to fibreoptic tracheal intubation with either a silicone DLT or PVC SLT (DLT and SLT groups, respectively). Time to tracheal intubation [time to insertion of FOB plus railroading (advancement over the FOB) time]; total time for correct tube and bronchial blocker positioning; difficulty of railroading; and the incidence of sore throat, swallowing difficulty, and hoarseness were compared between groups.
Results: The median time to intubation over the FOB was 20 s in the DLT group and 23 s in the SLT group. The upper limit of the confidence interval of this difference was below the non-inferiority margin of 10 s (median difference: –2 s; 95% confidence interval: –4 to 0 s). Railroading time was significantly shorter in the DLT group than in the SLT group (median time: 10 vs. 11 s; median difference: –1 s; 95% confidence interval: –3 to 0 s; P=0.03). Railroading over the FOB (rated on a four-point scale) was less difficult in the DLT group than in the SLT group (P},
