A periscope-based, 3D printed indirect laryngoscope for resource limited settings: a non-randomized observational manikin trial.

ABSTRACT: In the United States and other resource-rich settings, video laryngoscopy is often favored for emergency intubation over direct laryngoscopy due to ease of use and improved performance in difficult airways. Video laryngoscopes pose a significant cost barrier against adoption in low- and middle-income countries (LMICs). In this study, we designed and tested a low-cost, 3D printable, periscope-based laryngoscope that achieves an indirect view of the vocal cords without the use of a video camera. The absence of expensive video components allows this device to be manufactured for $4.41 USD, making it well-suited for resource-limited settings. The periscope-based laryngoscope was manufactured from polylactic acid (PLA) filament using a 3D printer. Manikin testing of the laryngoscope was perform
