This study investigate the utility of continuous oxygen insufflation during fiberoptic
bronchoscope-guided intubation.
One group receives oxygen via suction channel of fiberoptic bronchoscope during intubation.
The other group does not receive oxygen during fiberoptic bronchoscope-guided intubation.
Then, the velocity of deoxygenation difference of PaO2(baseline

Primary | Velocity of PaO2 decrease | After administration of anesthetic agents and manual ventilation of 5 minutes, arterial blood sampling is collected. Then bronchoscope-guided intubation performed and arterial blood sample is collected immediately after the intubation completed. Time for intubation (between 1st and 2nd blood sample) is recorded. The difference of PaO2(before & after intubation) is divided by the time taking for intubation. | from mask removal to 1st manual ventilation after intubation, up to 5 minute | |
Secondary | success of intubation | After 1st trial of intubation, the success of intubation is recorded. If it takes more than 300 sec, it will be considered failure. | 300 sec after the beginning of intubation | |
Secondary | PaO2 | arterial blood samples are collected before and after intubation. | 1. 5 minutes after manual ventilation / 2.right before 1st manual ventilation after intubation, up to 5 minute | |
Secondary | PaCO2 | arterial blood samples are collected before and after intubation. | 1. 5 minutes after manual ventilation / 2.right before 1st manual ventilation after intubation, up to 5 minute | |
Secondary | pH | arterial blood samples are collected before and after intubation. | 1. 5 minutes after manual ventilation / 2.right before 1st manual ventilation after intubation, up to 5 minute | |
Secondary | visual field | Visual field is evaluated by the blinded observer. It is evaluated as followed;excellent, good, poor, impossible | throughout the intubation with bronchoscope, upto 5 minute |
