“…Cormack-Lehane (C&L) scoring is used to grade the glottic appearance during direct laryngoscopy. So far, there is no definitive grading system for video laryngoscopes [10]. The present study recorded the C&L score by direct laryngoscopy employing a Macintosh laryngoscope in all patients before endotracheal intubation.…”

Background and objectives: In patients with Covid-19, using a video laryngoscope as an alternative to direct laryngoscopy is recommended to protect the intubator from infection and reduce intubation failures due to personal protective equipment. The cost of video laryngoscopes limits their availability in all healthcare institutions. The present study aimed to compare the efficacy and safety of 3D printed video laryngoscope and conventional video laryngoscope on intubation. Material and methods: 30 ASA I-II patients who were not considered to have a difficult airway were included in the study after obtaining the ethics committee approval from Adnan Menderes University Clinical Research Ethics Committee. Patients were randomly divided into two groups, group 1 and group 2. After the induction of anesthesia under standard monitoring, the Cormack Lehane score was recorded by direct laryngoscopy in all patients. Patients in group 1 were intubated with a 3D-printed video laryngoscope. In contrast, patients in group 2 were intubated with a conventional video laryngoscope (STORZ C-mac videolaryngoscope). Intubation time, number of attempts, and hemodynamic values of patients with early postoperative complications were recorded. The data were recorded and statistically evaluated. Results: There were no significant differences between the groups regarding demographic data, BMI, and hemodynamic data. The Cormack Lehane score was calculated as 1.6±0.51 in group 1 and 1.4±0.51 in group 2 (p=0.38). Intubation times of the groups were 32.6±18 s and 27.06±11.37 s, respectively (p=0.4). The number of intubation attempts was 1.2±0.63 in group 1 and 1±0.01 in group 2 (p=0.31). The image quality of the camera by the intubator, intubation conditions, and intubation satisfaction was similar in the two groups. Conclusion: Comparing a 3D-printed videolaryngoscope with a conventional videolaryngoscope, no differences were observed in intubation times, number of intubation attempts, hemodynamic changes, and early postoperative complications. Intubation satisfaction values by the practitioner were found to be similar. It was concluded that the 3D-printed videolaryngoscope, which is cost-effective and easy to access, can be used instead of conventional videolaryngoscope in patients with a normal airway.

“…VDL, which relies on video technology to transmit images from the distal part of the laryngoscope to the eyepiece or monitor, has strong maneuverability and wide visibility and can clearly show the physiological and anatomical structures of the throat and airway, which are designed to assist in difficult intubation and reduce failure, trauma, and complications. [ 8 , 9 ] However, in China, most studies have been focused on the application effect of VDL in tracheal intubation under general anesthesia and not on its effect on emergency critically ill patients. [ 10 , 11 ] Therefore, the aim of the present study was to compare the effect of VDL and conventional direct laryngoscopy in endotracheal intubation in critically ill emergency patients to help clinicians establish a rapid endotracheal intubation program.…”

To investigate the safety and efficacy of video laryngoscopy for endotracheal intubation in critically ill patients. A total of 106 critically ill emergency patients treated at our hospital between January 2021 and June 2022 were randomly divided into 2 groups, the visual and direct groups, with 53 patients in each group. Both groups were treated with endotracheal intubation; the visual group was treated with video laryngoscopy, and the direct group was treated with conventional direct laryngoscopy. The Cormack–Lehane grade, percentage of glottic opening score, success rate of one intubation, intubation time, number of intubation attempts, hemodynamic values, and complications were compared between the 2 groups. The success rates of glottis exposure and one-time intubation were significantly higher while the intubation time and number of intubation attempts significantly lower in the visual group than in the direct group. The heart rate, mean arterial pressure (MAP), or blood oxygen saturation did not differ significantly between the 2 groups 10 minutes after entering the room (T0) or after anesthesia induction (T1). MAP was significantly lower in the visual group than in the direct group during immediate intubation (T2). The heart rate and MAP were significantly lower in the visual group than in the direct group 1 minute (T3) and 5 minutes (T4) after intubation. The incidences of intubation-related complications in the visual and direct groups were 7.55% and 22.60%, showing a significant difference. Endotracheal intubation under videolaryngoscopy is safer and more effective for critically ill emergency patients than conventional direct laryngoscopy. This can improve the success rate of intubation, reduce the intubation time, and reduce its effect on hemodynamics. Therefore, it is worthy of further clinical application.

The Use of the Shikani Video-Assisted Intubating Stylet Technique in Patients with Restricted Neck Mobility

Among all the proposed predictors of difficult intubation defined by the intubation difficulty scale, head and neck movement (motility) stands out and plays as a crucial factor in determining the success rate and the degree of ease on endotracheal intubation. Aside from other airway tools (e.g., supraglottic airway devices), optical devices have been developed and applied for more than two decades and have shown their superiority to conventional direct laryngoscopes in many clinical scenarios and settings. Although awake/asleep flexible fiberoptic bronchoscopy is still the gold standard in patients with unstable cervical spines immobilized with a rigid cervical collar or a halo neck brace, videolaryngoscopy has been repeatedly demonstrated to be advantageous. In this brief report, for the first time, we present our clinical experience on the routine use of the Shikani video-assisted intubating stylet technique in patients with traumatic cervical spine injuries immobilized with a cervical stabilizer and in a patient with a stereotactic headframe for neurosurgery. Some trouble-shooting strategies for this technique are discussed. This paper demonstrates that the video-assisted intubating stylet technique is an acceptable alternative airway management method in patients with restricted or confined neck motility.
