Brief Summary

The fiberoptic bronchoscope (FOB) has been the preferred instrument for many years in the management of difficult tracheal intubation, and it is considered as a gold standard. The disposcope endoscope (DE) is a medical device for endotracheal intubation used in clinical practice recently.This study compares FOB and DE for awake orotracheal intubation in obese patients with anticipated difficult airway.

Outcome Measures

Primary Outcomes (1)

  • Intubation Time

    36 months

Secondary Outcomes (1)

  • Occurrence of throat pain measured by VAS

    36 months

Study Arms (2)

Fiberoptic bronchoscope

EXPERIMENTAL

In case of FOB, the FOB was inserted into oral cavity, and the epiglottis and glottis were identified by the FOB. The anterior of FOB was inserted deep into tracheal after the glottis was exposed sufficiently then the tracheal tube was pushed into the trachea via the FOB

Device: Fiberoptic bronchoscope

Disposcope endoscope

EXPERIMENTAL

In the DE group, the operator gripped the chin and lower incisors of patients with the fingers and thumb to open the mouth adequately wide and grasped the wire body, which was enclosed within the endotracheal tube, by the other hand and held it parallel to,then inserted into oral cavity

Device: Disposcope endoscope
