Comparing the "Snifing Position" , "Simple Head Extension" and "Neutral Position"

Not Applicable

Completed

• Conditions: Therapeutic Procedural Complication

• Registration Number: NCT05331287
• Lead Sponsor: The First Hospital of Qinhuangdao

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Intubation Time	Ten minutes	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.
