Outcomes in video laryngoscopy studies from 2007 to 2017: systematic review and analysis of primary and secondary endpoints for a core set of outcomes in video laryngoscopy research.

In recent video laryngoscopy studies, many different and inhomogeneous parameters were used as outcome descriptors/endpoints. Based on these findings, we recommend that 19 specific parameters (e.g., "time to intubation" (inserting the laryngoscope to first ventilation), "laryngeal view grade" (C&L and POGO), "successful intubation rate", etc.) should be used in coming research to facilitate future comparisons of video laryngoscopy studies.
