About

The purpose of this study is to comparing the effects of different double-lumen endotracheal tube's bending type in tracheal intubation.

Full description

Intubation with the double-lumen endotracheal tube (DLT) remains a great challenge for anesthesiologists. Although new upper airway devices, such as GlideScope(R) videolaryngoscope, had been developed for facilitating airway management, the larger size and the complexity of DLT than single-lumen tube (SLT) makes the difficulties for DLT intubation. Therefore, the investigators designed this study to investigate the effects of different bending type of DLT in tracheal intubation.
