Double-lumen bronchial tube (DLT) had been demonstrated to benefit for thoracic surgery and also played an important role to achieve one-lung ventilation (OLV) for exploring the surgical fields. However, compared with the single-lumen endotracheal tube (SLT), the DLT had larger OD (outer diameter), longer length, and was more complex in its structure. For avoiding oral tissue trauma and shortening the DLT intubating time, thus, an adequate and complete glottic viewing under laryngoscope was needed. Over the past decade, several video-assisted laryngoscopes had been developed to facilitate the tracheal intubation in the difficult airway. Among these devices, the GlideScope® videolaryngoscope (GVL) (Verathon, Bothell, WA, USA) was a reusable video laryngoscope with a 60° curvature blade. A light source and a digital video camera were installed at the tip of the laryngoscope blade and the pictures of the glottis and the vocal cords were displayed on an LCD monitor. We could insert the endotracheal tube passing the vocal cords into the trachea more precisely and had less tissue damaging under the GVL's guidance. Compared with direct MacIntosh laryngoscope, the GVL had been reported that it can decrease the intubation time and increase the successful rate of first intubation in normal and difficult airways. However, the efficacy of the GVL in intubating the DLT was unclear and had never been evaluated. Therefore, the aim of this study was to compare the intubation conditions, safety, and patient comfort between using the GVL and the direct Macintosh laryngoscope in a specific population of patients needed DLT intubation. Main outcome measures were intubation success rates and the time needed to intubate the DLT with the two devices.
