Flexible tip bougie - the new introducer for intubation during cardiopulmonary resuscitation: A randomized crossover manikin study

BACKGROUND: The aim of this study was to compare three intubation methods during cardiopulmonary resuscitation using an adult-manikin. METHODS: Thirty-nine paramedics were included in this study. Each participant performed endotracheal intubation during continuous chest compressions using 3 different methods: conventional Macintosh laryngoscope without additional intubation aids (MAC), conventional Macintosh laryngoscope with gum-elastic bougie (GEB), or flexible tip bougie (FTB). First attempt intubation success rate and intubation time was measured. RESULTS: Intubation success rate was 39% with the use of MAC, 92% with GEB and 95% with FTB. It was statistically lower with MAC than with GEB (P < .001) and FTB (P < .001). There was no difference between GEB and FTB in intubation success rate (P = .644). The mean(SD) intubation time was 28.43 (13.81)s with MAC, 25.69 (5.35)s with GEB and 21.41 (2.88)s with FTB. Intubation time was significantly longer with GEB than with FTB (P < .001). CONCLUSIONS: Within limitations, results of our study suggest that intubation aids facilitate tracheal intubation during continuous chest compressions. Using flexible tip bougie shortens the duration of the procedure compared to gum elastic bougie.
