Outcome of video laryngoscopy versus direct laryngoscopy for emergency tracheal intubation in emergency department: a propensity score matching analysis

Abstract: BACKGROUND: The high incidence of airway management failure in the emergency department (ED) necessitates a comparative analysis of laryngoscopy methods. This study aims to compare the success and complications associated with video-assisted laryngoscopy (VL) and direct laryngoscopy (DL) in emergency tracheal intubation in ED. METHODS: ). The outcomes assessed were success rates of intubation and occurrence of peri-intubation adverse events. Propensity score matching and multivariable risk regression analysis were employed for statistical evaluation. RESULTS: The study included 3,424 patients, with 342 in the VL group and 3,082 in the DL group. The initial analysis revealed no significant differences in the intubation success rates between the two methods. However, the VL group experienced fewer peri-intubation adverse events (33% compared to 40%). After propensity score matching, a higher first-attempt success rate was observed in the DL group (88.9% vs. 81.3%, risk difference: 7.6, 95% CI: 1.9 to 13.2, p=0.009), but there was no statistically significant difference in peri-intubation adverse events. VL had a lower first-attempt success rate among low-experience intubators. Subgroup analyses of intubators with moderate and high experience, as well as patients who received both induction agents and neuromuscular blocking agents, show results consistent with the analysis of the entire cohort. CONCLUSION: Both VL and DL have comparable first-attempt success rates and peri-intubation adverse events. VL is particularly beneficial when used by moderately or highly experienced intubator. The choice of intubation method, combined with clinical experience and technique plays a critical role in the success and safety of emergency intubations.
