Novel co-axial, disposable, low-cost 3D printed videolaryngoscopes for patients with COVID-19: a manikin study.
Article in European journal of anaesthesiology and intensive care, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundCOVID-19 continues to present challenges to both patient management and the protection of the airway management team involved, in particular in resource-constrained low-income countries. Among the most concerning complications in affected patients is rapid hypoxemic respiratory failure requiring tracheal intubation and mechanical ventilation. Videolaryngoscopy without peri-intubation oxygenation is the recommended approach in COVID-19 patients. However, the absence of peri-intubation oxygenation during intubation attempts can lead to hypoxia, and result in life-threatening complications in already critically ill patients.
objectiveTo develop low-cost disposable 3D printed videolaryngoscope designs with integrated channels for oxygen, suction, WIFI-enabled camera and tracheal tube channels, as well as a flexible transparent barrier anchor to offer optional additional protection to the user and airway management team.
designA manikin study. SETTING AND
participantsThree experienced consultant anaesthetists in the Mater Misericordiae University Hospital, Dublin, Ireland.
main outcome measuresTo generate novel co-axial videolaryngoscopes that meet International Standards, ISO7376 : 2020 standards for anaesthetic and respiratory equipment (laryngoscopes for tracheal intubation), and to demonstrate successful tracheal intubation of a manikin trainer in a range of configurations ('easy' to 'difficult') in accordance with the Cormack-Lehane grading of laryngeal view.
resultsFinal design prototypes met the minimum criteria for strength and rigidity according to ISO7376 : 2020, including blade tip displacement under load (65 N and 150 N). Preliminary validation has demonstrated successful tracheal intubation of a manikin trainer in all configurations including 'difficult' (Cormack-Lehane Grade 3 view).
conclusionsThis low-cost, rapid in-house manufacture could offer a mitigation of supply chain disruptions that can arise during global pandemics. Furthermore, it could offer a low-cost solution in low-income countries where there is an infection risk caused by re-using most current videolaryngoscopes requiring sterilisation before re-use, as well as limitations in the availability of personal protective equipment.
