Abstract
Endotracheal intubation is the gold standard for airway management. Direct laryngoscopy is a difficult procedure with a high failure rate. A 3D printed video laryngoscope can be used as a more affordable replacement for a laryngoscope. The aim of this study was to evaluate the success rate and time of endotracheal intubation in manikins using the Alba 3D printed video laryngoscope, the C-MAC video laryngoscope and the Macintosh operated by medical students. This study was conducted using a cross sectional randomised study method involving 36 medical students. This study found that the mean endotracheal intubation time using Alba 3D Print was significantly shorter than using Macintosh, but not better than C-MAC (VL3D-25 vs LDM-50.5 vs VLC-21.5 s) with a p-value of <0.001. The success rate of endotracheal intubation using Alba 3D moulds was significantly better than using Macintosh, but not statistically significant when compared to C-MAC (VL3D-91.7% vs LDM-97.2% vs VLC-75%) with p-value <0.05). This study concluded that the use of Alba 3D prints has a better success rate and time compared to Macinctosh and can be an affordable alternative to commercial video laryngoscopes such as C-MAC for educational purposes.
