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

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.

About this study

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.

Influence of different head position on nasal endotracheal intubation

Primary outcomes

  1. Intubation Time

    Time frame: 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.

Secondary outcomes

  1. Occurrence of throat pain measured by VAS

    Time frame: one day Postoperative]
