Comparison of intubation techniques using standard geometric videolaryngoscope with bougie, hyperangulated videolaryngoscope, and videostylet in cadavers with only epiglottis visible.

ABSTRACT: Cormack-Lehane grade 3 airways, where only the epiglottis is visible, present significant challenges due to limited operator experience and poor patient positioning, with little evidence on the best videolaryngoscopy approach. This study evaluated the effectiveness of two emerging devices-a videostylet (VS) and a hyperangulated videolaryngoscope (HAVL)-in simulated grade 3 scenarios, compared to a standard geometry videolaryngoscope (SGVL) and SGVL with bougie assistance. Thirty-three second-year residents from various medical specialties, all with limited airway experience, were trained and randomly assigned to intubate two cadavers modified to replicate grade 3 views using each device. Outcomes included intubation success within 90 s, time to intubation, and difficulty rating via visual
