"Neutral Head Position" and "Head-lift Position" for Orotracheal Intubation With "Trachway" Intubating Stylet in Adults
- Conditions
- Intubation; Difficult
- Interventions
- Procedure: Head-lift positionDevice: 7cm high pillow
- Registration Number
- NCT02578992
- Lead Sponsor
- Tri-Service General Hospital
- Brief Summary
The purpose of this study is to investigate two different patient's head and neck positions(neutral head position and head-lift position) for the effectiveness of orotracheal intubation with using the "Clarus Video System (Trachway®)" intubating stylet.
- Detailed Description
The sniffing position has traditionally been considered the optimal head position for direct laryngoscopy, However, it may aggravate cervical spine injury. The Trachway® video stylet is an intubating device that may avoid cervical movement during intubation. Nonetheless, the effectiveness of limited neck movement in patients with neutral head or head-lift position using the Trachway® video stylet remains unclear. The purpose of this study was to compare the intubation time of the two positions with the Trachway® video stylet.

Group Intervention Description Head-lift Position Head-lift position The patients' head was placed in the head-lift position(A 7 cm high pillow was set beneath the patients' head with head in neutral position) and then the patient was intubated with Trachway by single-handed chin lift technique Head-lift Position 7cm high pillow The patients' head was placed in the head-lift position(A 7 cm high pillow was set beneath the patients' head with head in neutral position) and then the patient was intubated with Trachway by single-handed chin lift technique
- Primary Outcome Measures
Name Time Method Intubation Time from the intubating stylet touched the mouth to the capnogram shown, up to 30 seconds, and the sum of all attempts the interval from the intubating stylet touched the mouth to capnogram shown, with all attempts, and was recorded by an independent observer with a stop watch.
- Secondary Outcome Measures
Name Time Method Modified Cormack-Lehane Grade during intubation, after epiglottis was identified on the video monitor The laryngeal view was graded by the observer with modified Cormack-Lehane grade after epiglottis was identified on the video monitor.
Scale range (1, 2, 3, 4). Grade 1 is considered to be a better outcome while grade 4 is considered to be a worse outcome.Mean Arterial Pressure before and after intubation, up to 5 minutes compare the mean arterial pressure between two groups.
Visual Analog Scale of Sore Throat after anesthesia emergence 30 minutest, at post-anesthesia care unit All patients were asked to rate the degree of sore throat, using a visual analogue scale after anesthesia emergence in the post-anesthesia care unit.
Scale range: 0-10. 0 is considered to be a better outcome while 10 is a worse outcome.
