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

Overview

The simple head extension is recommended for optimization of glottic visualization during awake orotracheal intubation whith fiberoptic bronchoscope (FOB) . However, no study to date has confirmed its superiority over "sniffing position" . In a prospective, randomized study, the authors compared the sniffing position , simple head extension and "Neutral Position" in awake orotracheal Intubation.

The study included seventy-five patients with anticipated difficult airways. The sniffing position was obtained by placement of a 7-cm cushion under the head of the patient. The extension head position was obtained by by placement of a 7-cm cushion under the shoulder. The head position was randomized as follows: neutral position group (NP group), sniffing position group (SP group) or extension position group (EP group) Randomization was performed by placing index cards with the letter NP or SP or EP into75 sealed envelopes , which were then placed in random order. At the time of a patient's enrollment, the next available envelope was placed with the patient's chart. At the time of intubation, the envelope was opened and the sequence was thus determined.
