Considering the difficulty of endotracheal intubation (ETI) during cardiopulmonary resuscitation (CPR), easy learning of ETI is attractive. This is first clinical study to compare the ease of acquisition of skill in ETI during CPR using direct laryngoscopy (DL) and video laryngoscopy (VL) (GlideScope). We performed a prospective, historically controlled clinical trial. Out-of-hospital cardiac arrest patients were intubated during CPR between May 2011 and April 2013 by novice emergency physicians (EP). DL was used for ETI during the first year, and VL during the second year. CPR data was automatically recorded by pre-installed video and subsequently analysed. The primary outcome was the success rate of the first attempt at ETI. In addition, the time to visualization of the glottis (T-view), time to successful ETI from visualization of the glottis (T-insertion), time to successful ETI from first attempt (T-complete), duration of interruption to chest compressions, and incidence of oesophageal intubation were compared. Of 305 patients undergoing ETI during CPR, 83 were intubated by novice EPs. The success rate of first attempt ETI in the VL group (n = 49) was higher than that in the DL group (n = 34, 91.8% vs. 55.9%; p < 0.0001). The median times to T-view, T-insertion, and T-complete were significantly shorter with VL than with DL. Oesophageal intubation was observed only in the DL group (n = 6, 17.6%). The median duration of interruption to chest compression was greater with DL (7 [3-16] sec) than with VL (0 [0-0] sec). Improved skills were observed in the VL group after the first 3 months, but not the DL group during regular use for 1 year. Novice physicians could rapidly acquire skill in ETI during CPR using VL, while skill was not easily achieved using DL.
