Short Attention Span Summary
For experienced physician intubators, video laryngoscopy (VL) didn't improve first-pass success and may have decreased it slightly. But for less experienced, non-physician intubators, VL almost doubled first-pass success. This meta-analysis of 8 studies was limited by significant heterogeneity, including use of a variety of VL devices: C-MAC, Airway Scope, GlideScope Ranger, Airtraq, and King Vision.
VL is a good way to improve first-pass success in the prehospital setting, especially for care providers who don't intubate frequently. For a rant on VL, see Minh Le Cong's PHARM podcast, and Chris Nickson has a short post - DL vs. VL on LiTFL.
