Abstract

Background Effective airway management is essential for anesthesia providers, yet failed laryngoscopy remains a significant challenge for trainees and can lead to severe patient harm (Natt et al., 2016). Education often emphasizes initial intubation attempts rather than structured redirection strategies following failure. This study evaluated whether a combined simulation and educational infographic intervention could improve NAT-2 trainees’ confidence and competency in redirecting after an unsuccessful first attempt. Methods A pretest–posttest design was used with NAT-2 participants who first completed a demographic and confidence survey. Trainees attempted intubation on a mannequin after being told the initial attempt failed. Performance on redirection steps was assessed using a standardized 6-point Likert-scale checklist. Participants were then introduced to a single-page infographic outlining evidence-based steps to take after failed laryngoscopy and repeated the scenario. Post-intervention performance and confidence were assessed. Results Checklist performance significantly improved in 4 of the 6 measured steps, and self-reported confidence increased across all survey items, indicating meaningful gains in both objective skills and perceived readiness. Conclusion A concise educational infographic combined with simulation effectively enhances trainee airway redirection performance and confidence after failed laryngoscopy.
