“… 4 Among them, the Ovassapian airway (Teleflex Inc.) ( Figure 1 ), the Williams airway (SunMed Inc.), and the Berman airway (Vital Signs) are widely studied as typical devices. 3 , 5 , 6 In terms of the difference in structure, the distally curved portion of the Williams airway and Ovassapian airway 9 has no anterior and posterior walls, respectively. Conversely, the Berman airway has both walls.…”

The Sanuki airway is a single-use intubation oral airway designed for fiberoptic bronchoscope intubation. Sanuki airway has a bite block function and a wide lumen for the tracheal tube to pass through. Here, three cases are reported in which Sanuki airway was used for oral fiberoptic bronchoscope intubation. Case 1 is a patient who presented with reduced mouth opening and intraoral edema due to facial bone fracture. Case 2 is a patient who suffered from severe neck stiffness and had reduced mouth opening due to systemic psoriatic arthritis. Case 3 is a patient who suffered from multiple facial traumas and was in a full-stomach state. In all patients, advancing the tip of the bronchofiber into the larynx using Sanuki airway was possible under dexmedetomidine sedation, which contributed to the successful tracheal intubation. Using Sanuki airway may be considered an option for oral fiberoptic bronchoscope intubation in patients anticipated with difficult airways.

“…Sample size calculation was based on the hypothesis that intubation time in group L is not inferior to that in group S. Using a non-inferiority margin of 10 s, based on the ndings of previous research, [16,17] the minimum sample size was calculated to be 80 patients to achieve a power of 80% and a 2.5% risk of a type I error (one-side test). Non-inferiority would have been declared if the upper limit of the 97.5% con dence interval (CI) of the mean difference (VDLT intubation time in group L minus that in group S) in the intubation time was below 10 s.…”

Background: Video double-lumen tube (VDLT) intubation in lateral position is a potential alternative to intubation in supine position in patients undergoing thoracic surgery. This non-inferiority trial assessed the efficacy and safety of VDLT intubation in lateral position. Methodsː Patients (18-70 yr) undergoing right thoracoscopic lung surgery were randomized to either the left lateral position group (group L) or the supine position group (group S). The VDLT was placed under video larygoscopy. The primary endpoint was the intubation time. Secondary endpoints included VDLT displacement rate, intubation failure rate, the satisfaction of surgeon and nurse, and intubation-related adverse events. Resultsː The analysis covered 80 patients. The total intubation time was 52.0 [20.4]s in group L and 34.3 [13.2]s in group S, with a mean difference of 17.6s [95% confidence interval (CI): 9.9s to 25.3s; P=0.050], failing to demonstrate non-inferiority with a non-inferiority margin of 10s. Group L, compared with group S, had significantly lower VDLT displacement rate (P=0.017) and higher nurse satisfaction (P=0.026). No intubation failure occurred in any group. Intubation complications (P=0.802) and surgeon satisfaction (P=0.415) were comparable between two groups. Conclusionsː VDLT intubation in lateral position was inferior to supine position in terms of intubation time. Given that no patient in group L suffered from hypoxia or intubation failure during intubation and group L had a lower VDLT displacement rate, it is possible that patients with a body mass index of less than 30 kg/m2, no cardiorespiratory disease, and no difficult airway could be successfully intubated using VDLT in lateral position.

“…The idea of using laryngoscopy to facilitate other airway management tools (e.g., to achieve a better glottis visualization) is not new. In numerous reports, either DL or VL has been used to assist fiberoptic bronchoscopy (FOB) in various clinical scenarios [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. DL was also reported in combination with the fiberoptic stylet to assist in clinical and simulated difficult airway cases [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ].…”

Video-Twin Technique for Airway Management, Combining Video-Intubating Stylet with Videolaryngoscope: A Case Series Report and Review of the Literature

Direct laryngoscopy (DL) and videolaryngoscopy (VL) have been the most commonly used airway management modalities in the last several decades. Meanwhile, various optional airway tools (e.g., supraglottic devices, fiberoptic bronchoscopes) have been used for alternative rescue modalities when anticipated or unexpected difficulties in airway management has occurred. In recent decades, optical stylets and video-assisted intubating stylets have become another option for difficult airway scenarios. In contrast to other approaches, we have adopted the Shikani video-assisted intubating stylet technique (VS) for both routine and difficult airway management scenarios. In this case series report, we present the video-twin technique, combining a videolaryngoscope with a video-assisted intubating stylet in various clinical case scenarios. We propose that such a combination is easy to learn and employ and is particularly beneficial in situations where an expected difficult airway (EDA) is encountered.
