Faster Learning Curve with the GlideScope Than the Direct Laryngoscope

To compare learning curves for the direct laryngoscope (DL) and GlideScope video laryngoscope, researchers retrospectively analyzed adult intubations performed by first-, second-, and third-year emergency medicine residents over a 7-year period at a single academic medical center.

Of 1613 intubations, 1035 were initially attempted with the DL and 578 with the GlideScope. The GlideScope was chosen more often for trauma patients and those with difficult airway characteristics. First-pass success rates were similar for first-, second-, and third-year residents with the DL (about 70%). With the GlideScope, first-pass success rates improved with each year of training: 74%, 84%, and 90%.
