Difficult airway management in adults: Insights from an observational cohort study on the use of videolaryngoscopy and fiberoptic bronchoscopy in a direct laryngoscopy-based practice.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVideolaryngoscopy has significantly improved the management of unanticipated difficult airways and replaced other intubation techniques. The goal of this study was to identify the indications for using videolaryngoscopy and fiberoptic bronchoscopy for adult patients, where direct laryngoscopy is the standard intubation technique.
methodsOver a one-year period from January to December 2018, anesthesiologists were surveyed on their reasons for using a videolaryngoscope or fiberoptic bronchoscope for tracheal intubations. Additionally, retrospective data on all direct laryngoscopy intubations were collected for the same period from the anesthesia information management system.
resultsOut of 6251 tracheal intubations with direct laryngoscopy and 502 with videolaryngoscopy or fiberoptic bronchoscopy, data from 450 (89.6%) cases were collected. We excluded 46 cases where videolaryngoscopy and fiberoptic bronchoscopy were used for non-airway management reasons, resulting in 404 cases for analysis. Videolaryngoscopy was initially used in 356 (88.1%) patients. The primary reasons for using videolaryngoscopy or fiberoptic bronchoscopy were anticipated difficult intubation (218, 54.0%) and cervical pathology (109, 27.0%). Among the 42 cases of unanticipated failed direct laryngoscopy, videolaryngoscopy was used in 41 cases and fiberoptic bronchoscopy in 1 case. The overall rate of unanticipated failed direct laryngoscopy was 0.7%.
conclusionsThe routine use of videolaryngoscopy and fiberoptic bronchoscopy for anticipated difficult tracheal intubations led to a very low incidence of unanticipated failed tracheal intubations with direct laryngoscopy. Therefore, routinely using more expensive videolaryngoscopes for all intubations would prevent only very small numbers of unanticipated failed direct laryngoscopic intubations and is not financially justified.
