简要总结
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.
详细描述
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.

结局指标
主要结局
Intubation Time
时间窗: 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.
次要结局
- Occurrence of throat pain measured by VAS(one day Postoperative)
