“…Thus, jaw thrust was maintained until the tracheal tube passed into the vocal cord along the bronchoscope in the present study. The first-attempt success rate for tube advancement was 68% in the supine position and 66% in the 25°semi-sitting position, which are comparable to a previous study in which the firstattempt success rate was higher in the jaw-thrust group than the control group (71% vs 34%, respectively) [17].…”

SummarySecuring a clear airway is important for successful fibreoptic intubation. We investigated whether the jaw-thrust manoeuvre in the 25°semi-sitting position improves airway clearance compared with the supine position in 88 anaesthetised patients randomly assigned to the two positions. After induction of anaesthesia, the fibreoptic bronchoscope was advanced into the mouth along the dorsum of the tongue during the jaw-thrust manoeuvre. Airway clearance was assessed at the level of the soft palate and epiglottis. Patients in the 25°semi-sitting position had clearer airways (judged subjectively by a three-level scale) than those in the supine position at the soft palate level (p = 0.012). At the level of the epiglottis, airway clearance was equally good in both positions. The mean (SD) times to view the vocal cord and carina were shorter in the 25°semi-sitting position (4 (1) s and 8 (1) s, respectively) compared with the supine position (6 (3) s and 11 (3) s; p < 0.001, respectively). The time to achieve intubation was also shorter in the 25°semi-sitting position (21 (5) s) than in the supine position (25 (7) s; p = 0.018).

“…External methods of creating such an air space include applying chin lift or jaw thrust [55], or gentle positive pressure ventilation using an adapted face mask [56,57]. These manoeuvres improve the success rates at first attempt and decrease intubation times [58]. Internal methods include using intubating oral or nasal aids to splint open the airways; positive pressure ventilation via a 'modified nasal trumpet' [59]; tongue traction with Magill's forceps or with applied suction; lower mandibular lift with the operator's thumb; concomitant use of direct or indirect laryngoscopy devices; or SAD which then acts as a conduit [60].…”

“…In intubation using fiberoptic bronchoscope (FOB), partial or complete obstruction of upper airway makes the FOB insertion difficult [1], and many methods to relieve the obstruction have been reported. As FOB has become a strategic tool for endotracheal intubation [2,3], efficient positions for fiberoptic endotracheal intubation including patient head position, have been studied [4][5][6][7][8].…”

Background: In intubation using fiberoptic bronchoscope (FOB), partial or complete obstruction of upper airway makes the FOB insertion difficult. Thus, maneuvers to relieve such obstructions are recommended. There have been no studies to determine whether the sniffing or neutral position is superior for this purpose. Therefore, this study was performed to examine the effects of these two positions including vocal cord view. Methods: Fifty-four patients scheduled to receive general anesthesia by orotracheal intubation were eligible for inclusion in the study with informed consent. After confirmation of proper head positioning depending on the group, the view of the vocal cord was acquired in each position. Images were reviewed using the percentage of glottic opening (POGO) score. Results: A total of 106 images of vocal cords from 53 patients were obtained. The mean of difference of POGO score was 11.09, higher for the neutral position and standard deviation was 23.73 (p = 0.002). Neutral position increased POGO score in 31 patients and decreased POGO score in 13 patients compare to sniffing position (p = 0.017). There were no significant differences between the two head positions with regard to intubation time or degree of convenience during intubation. Conclusions: Neutral position improved the view of glottic opening than sniffing position during oral fiberoptic intubation. However, there was no difference in the difficulty of tube insertion between the two positions. Trial registration: Clinical Trials.gov identifier: NCT02931019, registered on October 12, 2016
