Evaluation of a New Portable High-Definition Video Laryngoscope (Tuoren VLHM5A) for Tracheal Intubation in Adults: Technical Report and Service Assessment.

Videolaryngoscopy (VL) is increasingly recommended as the primary technique for tracheal intubation, supported by major international guidelines, which endorse VL for routine use to provide improved glottic visualization, higher first attempt success, and reduced complications, including failed intubation and airway trauma. However, despite these advantages, VL adoption remains low due to higher cost, variations in devices, training limitations, and restricted availability. This technical report summarizes early institutional experience with the Tuoren VLHM5A - a new portable, high-definition (HD) VL system - used in 50 elective surgical patients. The device demonstrated excellent visualization, rapid intubation, and 100% first-attempt success in both "normal" and "predicted difficult" airways when used by experienced anesthesiologists in this preliminary experience. However, these findings should be interpreted with caution given the limited sample size and the absence of a comparator device. If confirmed in larger studies, portable HD VL systems may help address some of the barriers to wider VL adoption and support guideline-based airway management.
