Brief Summary

The simple head extension is recommended for optimization of glottic visualization during Nasotracheal intubation via fiberoptic bronchoscope (FOB) . However, no study confirmed its superiority over"snifing position" and "Neutral Position". In a prospective, randomized study, the authors compared the snifing position , simple head extension and "Neutral Position" in Nasotracheal intubation via fiberoptic bronchoscope.

Conditions

Therapeutic Procedural Complication

Keywords

Snifing Position; Simple Head Extension; neutral position; Nasotracheal intubation

Outcome Measures

Primary Outcomes (1)

• Intubation Time

  The primary endpoints were the time to view the vocal cords (TVC) which was taken when the operator indicated verbally that he view the vocal cords and the time to successful tracheal intubation (TSI). TSI was defined as the time taken from insertion of the FOB between the teeth until the appearance of a capnograhy curve.

  Ten minutes

Secondary Outcomes (1)

• Occurrence of throat pain measured by VAS

  one day Postoperative]

Study Arms (3)

snifing Position

EXPERIMENTAL

Nasotracheal intubation via fiberoptic bronchoscope under snifing position.The snifing position was obtained by placement of a 7-cm cushion under the head of the patient. When the FOB was inserted into Nasal 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.

Other: Head position

neutral position

EXPERIMENTAL

Nasotracheal intubation via fiberoptic bronchoscope under snifing position.The Head Extension was obtained by the occiput of the patient close to the operating table. When the FOB was inserted into Nasal 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.

Other: Head position

Head Extension

EXPERIMENTAL

Nasotracheal intubation via fiberoptic bronchoscope under snifing position.The extension position with a 7-cm pillow underneath the shoulder and the occiput close to the operating table. When the FOB was inserted into Nasal 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.

Other: Head position
