BMC anesthesiology
-
Airway management is crucial and, probably, even the most important key competence in anaesthesiology, which directly influences patient safety and outcome. However, high-quality research is rarely published and studies usually have different primary or secondary endpoints which impedes clear unbiased comparisons between studies. The aim of the present study was to gather and analyse primary and secondary endpoints in video laryngoscopy studies being published over the last ten years and to create a core set of uniform or homogeneous outcomes (COS). ⋯ 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.
