Abstract

Objective
The study compared the first-attempt success and complication rates of endotracheal intubation (ETI) using video laryngoscopy (VL; GlideScope) with those of direct laryngoscopy (DL) in the emergency department (ED).
Methods
This was a retrospectively clinical study of adult patients who underwent intubation using from 2010 to 2014 in the ED. All data were collected from the electronic medical records. The primary outcome was the first-attempt intubation success of ETI. The secondary outcomes were occurrences of desaturation, hypotension, oesophageal intubation, dental injuries, and cardiac arrest. The between-device differences in outcome risks were examined.
Results
A total of 431 emergency ETIs were included. The first-attempt intubation success rate was higher in the VL than DL (93.8% vs. 74.8%, P<0.001). The non-expert emergency physicians (first and second-year residents) showed a higher first-attempt intubation success rate in VL than DL, but there was no difference in the first-attempt intubation success rate between the two devices between experts (third and fourth-year residents). The use of VL was associated with a lower rate of desaturation (0.0% vs. 5.0%) and tooth injuries (0.0% vs. 2.7%) compared to the DL.
Conclusion
The use of VL was associated with a higher first-attempt success rate compared to DL, particularly in inexperienced intubators. For complications related to ETI, VL showed a lower rate of desaturation and dental injuries in the ED than the DL.
