Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study included ninety patients with anticipated difficult airways. The snifing position was obtained by placement of a 7-cm cushion under the head of the patient; the extension head position was obtained by placement of a 7-cm cushion under the shoulder; the neutral position with the occiput close to the operating table. The head position was randomized as follows: neutral position group (NP group), sniffing position group (SP group) or extension position group (EP group). Randomization (1:1:1) was based on the codes generated by Excel software, which were kept in sequentially numbered opaque envelopes until the began of study.

snifing Position

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.

neutral position

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.
