Comparing the "Snifing Position" , "Simple Head Extension" and "Neutral Position"
- Conditions
- Therapeutic Procedural Complication
- Interventions
- Other: Head position
- 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.

Group Intervention Description neutral position Head 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. snifing Position Head 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. Head Extension Head position Nasotracheal intubation via fiberoptic bronchoscope under snifing position.The extension position with a 7-cm pillow underneath the shoulder and the occiput 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.
- 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.
- Secondary Outcome Measures
Name Time Method Occurrence of throat pain measured by VAS one day Postoperative]
