Video Laryngoscopy Is Associated With First-Pass Success in Emergency Department Intubations for Trauma Patients: A...

We sought to (1) characterize emergency department (ED) intubations in trauma patients and estimate (2) first-pass success and (3) the association between patient and intubation characteristics and first-pass success.

We performed a secondary analysis of a multicenter prospective observational cohort of ED intubations from the National Emergency Airway Registry (NEAR). Descriptive statistics were calculated for all patients who were intubated for trauma at 23 NEAR EDs between 2016 and 2018. We evaluated first-pass success in patients intubated by (1) emergency or pediatric emergency physicians, (2) using rapid sequence intubation or no medications, and (3) either direct laryngoscopy or video laryngoscopy. We used propensity score matching with a generalized linear mixed-effects model to estimate the associations between patient and intubation characteristics and first-pass success.

Of the 19,071 intubations in NEAR, 4,449 (23%) were for trauma, and nearly all (88%) had at least one difficult airway characteristic. Prevalence of first-pass success was 86.8% (95% confidence interval [CI]: 83.3% to 90.3%). Most patients were intubated with video laryngoscopy, and patients were more likely to be intubated on first-pass with video laryngoscopy as compared to direct laryngoscopy (90% versus 79%). After propensity score matching, video laryngoscopy remained associated with first-pass success (adjusted risk difference 11%, 95% CI: 8% to 14%; and OR 2.2, 95% CI: 1.6 to 2.9). Additionally, an initial impression of difficult airway, blood/vomit in the airway, and use of external laryngeal manipulation were all associated with decreased odds of first-pass success.

Emergency physicians are successful at intubating patients in the setting of trauma, and video laryngoscopy is associated with twice the odds of first-pass success when compared to direct laryngoscopy.
