Homemade 3D-Printed Affordable and Practical Alternative Videolaryngoscope: First Step

Abstract

Objective: Changing economic conditions make it difficult for clinics to access the medical devices they need. Videolaryngoscope is one of the devices needed in many units such as operating rooms, intensive care and emergency services. Our study aims to design a low-cost videolaryngoscope (VL) using three-dimensional printing technology and offer clinics a cost-effective alternative to traditional VLs. Materials and Methods: Initially, three-dimensional images were obtained from the website www.thingeverse.com to form the basis of the videolaryngoscope blade. The Ultimaker Cura 4.0 program (Ultimaker B.V. Netherlands, Utrecht) was used to create three-dimensional drawings of the handle and blade prints. This drawing was produced on a 3D printer using polylactic acid as raw material. Finally, the wireless camera with 1080p HD resolution was positioned on the handle and blade. 3DPVL was tested on an intubation mannequin by a group of 30 anesthesiologists, each with at least 4 years of experience. The intubation times of the participants and their satisfaction with this process were recorded. Results: In the study, the intubation times performed by 30 anesthesiologists on a mannequin were recorded. It was determined that the average intubation time for 3DPVL was 24.3 seconds. 90% of participants rated the experience as good or excellent. Similarly, satisfaction levels were rated as good or excellent by 60% of participants. Conclusion: The affordable and practical of production associated with 3DPVL make it a potentially viable alternative to traditional VLs for clinicians. In the second step, a case series focusing on easy airways is planned regarding our device. In later steps, randomized controlled studies are planned between our device and traditional VL in easy and difficult airways.
