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% 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% compared to 84.3% for the reusable VL group. A non‐inferiority analysis indicated that the difference (−15.1%) and corresponding 90% confidence limits (−25.3% to −5.0%) did not fall within the predetermined 10% 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. [ABSTRACT FROM AUTHOR]
