Stylet Angle for McGrath Videolaryngoscopy

March 2, 2017 updated by: Jiyoung Lee, Ajou University School of Medicine
The McGrath videolaryngoscope (VL) provides excellent laryngoscopic views, but directing an endotracheal tube is not easy, so routine using of stylet is recommended. The goal of this study is to determine the appropriate angle of stylet by comparing time to intubation (TTI).
