“…However, studies on this subject remain limited. Studies available in the literature produced new VLs based on the existing VLs and DLs as examples, in addition to developing their own unique devices [4,9,10,19,[27][28][29][30]. PLA material, which is considered biocompatible, was generally used in manufacturing these devices.…”

“…Cohen compared 3D-PVL with MCL and reported the superiority of 3D-PVL over MCL in terms of rst entry success rate, glottic imaging, and intubation time [29]. Papanaoum et al revealed that 3D-PVL was more successful than MCL [27]. Similarly, Lambert et al compared 3D-PVL with MCL and Pentax-AWS® and revealed that 3D-PVL is superior to MCL in terms of intubation time and success, glottic imaging, and ease of use [4].…”

Background: Video laryngoscopy (VL) outperforms direct laryngoscopy (DL) in both normal and difficult airway situations. However, VL seems far from being offered as a standard option in both healthcare delivery and educational activities in low-income countries, considering its high costs. Therefore, three dimensional (3D)-printed VLs may be considered an alternative to conventional VLs in low-income countries and other places with limited resources. Our objective was to compare the efficacy of AirAngel 3D-printed VL (3D-PVL) with those of commercially available Storz® VL (SVL) and conventional Macintosh® laryngoscope (MCL) in normal and difficult airway scenarios in the hands of inexperienced users. Methods: This is a prospective randomized crossover manikin study that included 126 senior medical students with no experience in intubation. The effectiveness of all three laryngoscopy devices in the hands of inexperienced users was evaluated in terms of intubation time, glottic visualization, ease of use, endotracheal tube placement and intubation success rate. Between 2020 and 2022, 126 last year medical students participated in the study. Results: MCL resulted in significantly longer intubation times than 3D-PVL and SVL in the difficult airway scenario, with no significant difference between 3DPVL and SVL (Wilcoxon test, p < 0.016; Bonferroni correction MCL: 28.54 s; SVL: 26.68 s; 3DPVL: 26.64 s). Both SVL and 3D-PVL resulted in significantly better Cormack−Lehane grades in both normal and difficult airway scenarios, and thus provided better glottic viewing than MCL, with no significant difference between 3D-PVL and SVL (Wilcoxon test, p < 0.016; Bonferroni correction, MCL: 1.73; SVL: 1.29; 3DPVL: 1.25). SVL was the easiest (1: very easy, 5: very difficult) device for normal airway scenarios, while MCL was the most difficult (MCL: 2.64; 3DPVL: 1.98; SVL: 1.49). Conversely, no significant difference was found between 3DPVL and other devices in terms of ease of use in difficult airway scenarios and in terms of accurate placement of the endotracheal tube and successful intubation attempts. Conclusion: 3D-PVL is a good educational and possible clinical alternative to conventional VL, particularly in places with limited resources, due to its low cost.

“…It is essential, therefore, to produce validated medical devices with set instructions for manufacturing and use. 'Vamo', a 3D-printed laryngoscope with a hyper-angulated blade, was introduced recently by Papaoum et al [8]. It was done without any indication of what materials and AM technology were used.…”

BACKGROUND COVID-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. OBJECTIVE To 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. DESIGN A manikin study. SETTING AND PARTICIPANTS Three experienced consultant anaesthetists in the Mater Misericordiae University Hospital, Dublin, Ireland. MAIN OUTCOME MEASURES To 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. RESULTS Final 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). CONCLUSIONS This 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.
