Comparison of Different Bending Mode for Double-lumen Endotracheal Tube Intubation

Kaohsiung Medical University Chung-Ho Memorial Hospital66 enrolled

Overview

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

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.

Outcomes

Primary Outcomes

Main outcome measure is the successful rate of the first intubation compared with the two bending modes of DLT

Time frame: 12 month

Secondary Outcomes

Time frame: 12 months

the incidence of sore throat after extubation

Time frame: 12 months

the incidence of hoarseness after extubation

Time frame: 12 months
