Abstract
INTRODUCTION There is uncertainty about the optimal videolaryngoscope for awake tracheal intubation in patients with anticipated difficult airway. The use of channelled and unchannelled videolaryngoscopy has been reported, but there is a lack of evidence on which is the best option. METHODS We conducted a randomised clinical trial to compare the efficacy of the C-MAC D-Blade® vs. Airtraq® in adult patients (aged ≥ 18 y) scheduled for elective or emergency surgery under general anaesthesia with anticipated difficult airway who required awake tracheal intubation under local anaesthesia and conscious sedation. The primary endpoint was the first-attempt tracheal intubation success rate. Secondary outcomes included the overall success rate; number of tracheal intubation attempts; Cormack and Lehane glottic view; level of difficulty (visual analogue score); patient discomfort (visual analogue score); and incidence of complications. RESULTS Ninety patients (70/90 male (78%); mean (SD) age 65 (12) y) with anticipated difficult airways were randomly allocated to C-MAC D-Blade or Airtraq videolaryngoscopy. First-attempt successful tracheal intubation rate was higher in patients allocated to the C-MAC D-Blade group compared with those allocated to the Airtraq group (38/45 (84%) vs. 28/45 (62%), respectively; p = 0.006). The proportion of patients' tracheas that were intubated at the second and third attempt was 4/45 (9%) and 3/45 (7%) in those allocated to the C-MAC D-Blade group compared with 14/45 (31%) and 1/45 (2%) in those allocated to the Airtraq group (p = 0.006). There was no significant difference in overall tracheal intubation success rate (C-MAC D-Blade group 45/45 (100%) vs. Airtraq group 43/45 (96%), p = 0.494). DISCUSSION In patients with anticipated difficult airway, first-attempt awake tracheal intubation success rate was higher with the C-MAC D-Blade compared with Airtraq laryngoscopy. No difference was found between the two videolaryngoscopes in overall tracheal intubation success rate.

Abstract
Recent evidence has shown that fibreoptic intubation is still an indispensable technique for safe management of predicted difficult airways, despite the implementation of new technologies such as videolaryngoscopy. It is therefore our obligation as anaesthesia societies and as practicing anaesthetists to offer this technique to our patients in clearly designated situations.

Abstract
Awake fibreoptic intubation has been considered a gold standard in the management of the difficult airway. However, failure may cause critical situations. The aim of this study was to investigate the incidence and causes of failed awake fibreoptic intubation at a tertiary care hospital. The study was conducted at St. Olav University Hospital in Trondheim, Norway. Problems occurring during anaesthesia are routinely recorded in the electronic anaesthesia information system (Picis Clinical Solutions Inc.), including difficult intubations. We applied text search on all anaesthesia records between 2011 and 2021 and identified 833 awake fibreoptic intubations. The anaesthesia records were examined to identify failed awake fibreoptic intubations, the cause of failure and how the airway ultimately was secured. Among 233,938 patients who received anaesthesia, 90,397 received tracheal intubation and 833 received awake fibreoptic intubation. Twenty-nine of the procedures failed. In nine patients the failure caused loss of airway control with desaturation and hypoventilation. The major causes of failure were dislodged tube after induction of general anaesthesia (n = 8), patient distress (n = 5), tube not able to pass (n = 5), and airway bleeding (n = 3). The situations were primarily solved using direct laryngoscopy, with or without bougie, or with video laryngoscopy. Tracheostomy was performed in four patients. Awake fibreoptic intubation failed in 3.5% of patients, most often due to dislocation, problems passing the tracheal tube, or patient discomfort. The failure rate was higher than in previous studies.

Abstract
STUDY OBJECTIVE This systematic review and meta-analysis aimed to assess the superiority of airway nerve blocks versus airway anesthesia without nerve blocks for awake tracheal intubation (ATI). DESIGN Systematic review and meta-analysis of randomized controlled trials (RCTs). SETTING All studies that assessed the superiority of airway anesthesia technique for awake tracheal intubation were searched in PubMed, Web of Science, Cochrane Library, Ovid Medline, Embase and Chinese databases (including China National Knowledge Infrastructure, Wanfang database, and VIP databases) and trial registry databases from their inception to December 2022. PATIENTS Adult patients included in randomized controlled trials comparing airway anesthesia with or without airway nerve blocks for ATI. INTERVENTIONS Airway nerve (including superior laryngeal nerve, glossopharyngeal nerve, or recurrent laryngeal nerve) blocks for ATI. MEASUREMENTS The primary outcome was the intubation time. Secondary outcomes were quality of intubating conditions (including patient reaction to placement of the flexible scope and tracheal tube, coughing and gagging, and patient satisfaction) and overall complications during ATI. MAIN RESULTS Fourteen articles with 658 patients were identified for analysis. When compared with airway anesthesia without nerve blocks, airway nerve blocks significantly reduced intubation time (standardized mean difference [SMD] -2.57, 95% CI -3.59- -1.56, p < 0.00001), improved anesthesia quality of ATI with higher no reaction to placement of the flexible scope and tracheal tube (relative risk [RR] 9.87; 95% CI 4.10-23.75, p < 0.00001), lower cough or gag reflex during intubation (RR 0.35, 95% CI 0.27-0.46, p < 0.00001), higher excellent patient satisfaction rate (RR 1.88, 95% CI 1.05-3.34, p = 0.03), and lower overall complications (RR 0.29, 95% CI 0.19-0.45, p < 0.00001). The overall quality of evidence was moderate. CONCLUSIONS Based on current published evidence, airway nerve blocks provide better airway anesthesia quality for ATI with a shorter intubation time, better intubation conditions including higher no reaction to placement of the flexible scope and tracheal tube, lower cough or gag reflex during intubation, higher excellent patient satisfaction, and lower overall complications.

A learning curve of a novel multimodal endotracheal intubation assistant device for novices in a simulated airway: a prospective manikin trial with cumulative sum method. Transl Pediatr 2022; 11:1389-1397. [PMID: 36072535 PMCID: PMC9442200 DOI: 10.21037/tp-22-405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 08/23/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND Awake fiberoptic intubation is conventionally performed in anticipated difficult airways. However, obstruction by secretions and sputum makes it challenging for novices. A prototype of a novel multimodal endotracheal intubation assistant device (MEIAD) was developed for an indication of airway according to end-tidal carbon dioxide (ETCO2) and image. At the tip, 4 sampling tubes collected ETCO2 concentration. The airway direction is located according to an advanced algorithm based on 4 directions' concentrations. It assists awake intubation, especially with unclear view field. The objective was to analyze the learning curve of MEIAD for novices on a manikin by cumulative sum method (CUSUM) and evaluate the utility. METHODS A total of 16 novice residents with less than 2-year clinical experience were enrolled. After instruction, each individual exercised 40 insertions with MEIAD on a difficult airway simulation. Insertion success (defined as a visualization of the carina within 120 seconds), insertion time (the time from when the guiding scope entered the nasal cavity to the carina was visible), and self-confidence score (subjective score with a numerical rating scale from 0 to 10) were recorded. The acceptable and unacceptable failure rates of CUSUM were set as 15% and 30%, respectively. The exercises were divided into 2 phases (phase 1: 1-20, phase 2: 21-40) for further evaluation. All continuous data were expressed by median (IQR, interquartile ranges) and analyzed using Mann-Whitney test. All categorical variables were expressed as percentages and compared by the χ2 test. RESULTS Among the 16 residents, 15 were able to cross the lower decision boundary in an average of 21.27±9.51 attempts using the novel device. The insertion time [24.0 (17.0-42.0) vs. 17.5 (14.0-28.0) seconds, P<0.001] and success rate (88.4% vs. 97.5%, P<0.001) were improved with increased experience. The confidence score was significantly improved from 2.5 (1.3-4.0) to 7.0 (7.0-8.0). CONCLUSIONS MEIAD showed a satisfactory learning curve and efficacy on the manikin for novices. However, as a small exploratory manikin trial, the results cannot be replicated in clinical practice. MEIAD is expected to be further improved and potential to be an alternative device for difficult airways.
