An Assessment of the Novel, Disposable, i-View Video Laryngoscope for far-Forward Endotracheal Intubation
Abstract
Introduction: Video laryngoscope (VL) technology improves first-pass success. The novel i-view VL device is inexpensive and disposable. We sought to determine the first-pass intubation success with the i-view VL device versus the standard reusable VL systems in routine use at each site. Methods: We performed a prospective, pragmatic study at two major emergency departments (EDs) when VL was used. We rotated i-view versus reusable VL as the preferred device of the month based on an a priori schedule. An investigator initiated interim analysis was performed. Our primary outcome was a first-pass success with a non-inferiority margin of 10 percent based on the per-protocol analysis. Results: There were 93 intubations using the reusable VL devices and 81 intubations using the i-view. Our study was stopped early due to futility in reaching our predetermined non-inferiority margin. Operator and patient characteristics were similar between the two groups. The first-pass success rate for the i-view group was 69.1 percent compared to 84.3 percent for the reusable VL group. A non-inferiority analysis indicated that the difference (-15.1 percent) and corresponding 90 percent confidence limits (-25.3 percent to -5.0 percent) did not fall within the predetermined 10 percent non-inferiority margin. Conclusions: The i-view device failed to meet our predetermined non-inferiority margin when compared to the reusable VL systems with the study stopping early due to futility. Significant crossover occurred at the discretion of the intubating operator during the i-view month.
