Comparing Combined Video Laryngoscope with Video Stylet Versus Combined Video Laryngoscope with Fiberoptic Bronchoscope for Simulated Difficult Airway Intubation

What this Trial Is About

This research aims to compare two advanced intubation techniques used in managing simulated difficult airways combined video laryngoscope with video stylet VL with VS and combined video laryngoscope with fiberoptic bronchoscope VL with FOB. This study addresses the lack of direct comparisons between these two combined approaches in Malaysia, with the goal of guiding airway management protocols and improving outcomes in challenging airway situations. It is a randomized comparative crossover trial involving experienced anaesthesiology medical officers and trainees. Participants will perform intubations in a simulated difficult airway setting using three methods video laryngoscope VL alone as the control, combined VL with VS, and combined VL with FOB. Each participant will randomly receive the sequence of combination techniques with a five-minute washout period between attempts. Standardized devices, including the C-MAC4 video laryngoscope, video stylet, and Karl Storz fiberoptic scope, will be used alongside a manikin with a cervical collar to simulate a difficult airway. During the study, participants will be timed for each intubation phase and asked to rate the ease of intubation using a 5-point scale. Successful intubation is confirmed via video monitoring and chest inflation within 60 seconds, allowing up to three attempts per technique. Data collected will include first-pass success rate, intubation times, glottic visualization scores, and participant preferences. The study concludes on the same day of simulation, with dropouts noted if participants do not complete all procedures or withdraw.
